3 Helpful Tips for system installation and setup a. Select digital input to get better image and avoid image position shift. b. If 4k signal connection distance is more than 10m, please select a certified HDMI cable to avoid unstable signal connection. Usually [High Speed HDMI + Ethernet] cable will be better. c. The quality for signal adapter or converter, such as HDMI to DVI adapter and DisplayPort to HDMI converter, may downgrade the signal quality and cause issue. Please select qualified ones. d. If user can see blue background image with [Power Saving Mode] message, it means the signal connection between projector and GeoBox is OK but no input signal detected by GeoBox. Please check signal source or replace a different input source to test. e. If user can t see [Power Saving Mode] message or splash screen, please check the connection between GeoBox and projector. User can connect to a monitor to check the output from GeoBox. [Loop out] port is for raw signal daisy chain connection and is not an output to projector. f. The output resolution setting shall be the same as projector native resolution to get the best video quality. After geometry alignment, this output resolution can t be changed. Otherwise, geometry position will be shifted and required further adjustment. g. In the application with short throw ratio projector on curved screen, it is possible that the image location is beyond the maximum adjustment range in manual adjustment. In this case, Gwarp PC tool is required to double the adjustment range. h. During installation setup process, please apply FHD signal to the system for easy setup. After finish the setup, user can select optimized EDID from OSD menu to get optimized video quality. i. The optimized EDID resolution should be the final resolution after edge blending. For instance, if user uses three XGA projectors for edge blending with 250 overlapped pixels, then the best signal for this setup will be 1024*3-250*2=2572. It means 2572*768 will be the best signal resolution for this setup. User can customize EDID with this resolution in GeoBox. Some PC may not be able to output the same custom resolution. In this case, user needs to set PC output resolution as close this timing as possible. GeoBox can support none-vesa standard input timings. j. In addition to the resolution settings, user needs to provide content with the same aspect ratio as screen to ensure no distortion on the screen. k. To reset all projectors before edge blending to get the same settings in all projectors. l. To turn off auto keystone function to avoid image shift. m. In order to avoid interference among multiple GeoBox during the installation, user can set ID number for each GeoBox through [Options] Menu. Press number keys in Remote Controller for the control of multiple GeoBox: 850: simultaneous control for all GeoBox 851: control GeoBox ID No. 1 853: control GeoBox ID No. 3 User will see flashing LED on front panel after press 85x number keys. It means the OSD menu in GeoBox with flash LED is locked and will not be controlled by remote controller. n. OSD Lock / Unlock: When continuously press [OKD Lock] key on Front Panel or [Menu] key in IR Remote Control for 5 seconds, the OSD function will be locked to prevent from setting change by 4
negligence. To press [OSD Lock] key or [MENU] key for 5 seconds again, it will unlock OSD and user can manipulate the OSD again. o. [Image Setup] menu will not be activated if the input source is not from VGA. p. Please reset GeoBox before any new application to avoid unexpected settings in the system. If deeper reset is required, user can turn on GeoBox and press both [Menu] + [Pattern] key on front panel and power on GeoBox again for 5 seconds. It will reset the system q. To set [Menu Time Out] to 0, the OSD will appear till the OSD Menu has been turned off manually or system input timing change. r. Default Internal Grid Pattern represents 32x32 pixels no matter which input resolution is selected. s. Only HDMI-A input port can provide HDMI raw signal loop out for daisy chain connection. This loop out signal has no any processing. t. When [Gwarp] PC tool is used, user needs to save the setting into GeoBox through the OSD menu: [Anyplace] [Gwarp Pro] select [UserMap 1-10] to save the settings. Then PC can be removed. u. When Power Off/ON GeoBox, it will maintain the final settings. v. User needs to save the final setting into [Profile] under [Options] menu for long tern stored inside the system. Even the system is reset, the [Profile] settings will be kept without change. w. Continuously press PATTERN button, internal test pattern will show different colors for easy installation: White Red Green Blue Blank. When in Blank, user can see OSD and the image from signal source. In this case, PC test pattern can be applied. x. Please use INFO hot key on front panel or remote controller to check the input and output timing. The indicators on the front panel will show the input/output connection status. y. User can set black background while no input signal is detected and input timing change under [Options] [Accessibility] menu. z. Below hotkeys are available in remote controller: [Warp] geometry alignment, [Video wall], [Edge Blend], [Info], [CH A/B] switching. 5
4 Edge blending procedures 4.1 System connection a HDMI Loop Out port is for daisy chain connection. It is not an input port. b Only the input signal from HDMI-A input port can be looped out. c Two outputs from will come from the same signal source. It is not for 2 independent displays. d User needs to use Micro USB cable for PC & connection if Gwarp PC Tool is used. User can extend USB control distance through USB extension cable. e IF GeoBox is installed in control room, please extend IR receiver to a place for easy remote controller access. User can use audio cable as extension cable. f User can execute OSD operation through Ethernet connection. g Select input port and set GeoBox output resolution to be same as projector native resolution. h User needs to apply a signal source while video wall [Overlap] value setting. Signal source resolution should be the same as Excel calculation. To apply 1080p signal is recommended. i Press [INFO] hotkey to check if the final in/out timings are the same as expected. 4.2 Excel Spread sheet calculation a User needs to get below data for edge blending plan: (3x projectors as Example) Input signal resolution: (3840*800) Number of projector.(3 projectors) Projector resolution and lumens. (1280*800, 3200 Lum) Required image size (screen size: 6.5m*1.5m) 6
Overlap pixels and dimension. (8 grids=8*32= 256 pixels) Projector throw ratio: 1.2-1.7 Based on these data, user can make a layout plan and decide the installation dimensions and locations. b The above is the calculation result. Please contact dealer or factory to get necessary assistance for these data. Final image size for each projector: 2.500m*1.563m User can use geometry alignment to draw the vertical height to the dimensions you need. In this example, the final image height is 1.5m after geometry alignment. Optimized content resolution: 3328*800 (This is the ideal resolution to set EDID) Installation distance: 3m-4.25m It is calculated from throw ratio and image wide for each projector. (2.5m*1.2=3m) The overlap value in video wall setting: -Projector LH: select RH edge: +197 -Projector (Center): LH edge=+98, RH edge=+99 (total 197) -Projector RH: LH edge: +197 -After finish setting, user can check the image, if some overlap area is still blurred, user can increase or decrease Overlap Value with 1-2 steps and select optimized one. The final luminance is 819 Lux. It will be enough for inside room environment. c It is allowed to have different overlap pixel among all projectors. Irregular Spread Sheet is required to calculate the result. 4.3 Mark image location After Excel Spread Sheet calculation, user can understand the final image position for each projector. Please mark image position by paper adhesive tape on the screen. The positions should include 4 corners of the image for each projector and horizontal center line of the screen. Please select a tape that will not damage the screen. 4.4 Set overlapped region size 7
a During Excel Spread Sheet calculation, user has some flexibility to determine the overlap region size by different projector resolution, lumens and number of projector. b Please reserve 200-500 overlapped pixels or 40cm-70cm overlapped region (it will also depend on screen size and Excel calculation). maximum edge blend region is 900 pixels. If it is over 900 pixels, user can change the projector installation location, lens shift adjustment, projector display aspect ratio or reduce overlap region by geometry alignment. c [9x5 Curved] will cut the horizontal image into 8 sections and the image in each section can be independently adjusted. In different output resolutions, there will be different pixel number in each section: XGA: 1024/8=128, WXGA: 1280/8=160, 1080p: 1920/8=240. Usually, [9x5 Curved] alignment is enough for most of the curved screen edge blending. d If the overlapped area between two adjacent projectors has the same or multiple number as above, the geometry alignment in overlap region will have less flexibility. User can increase or decrease one or two grids (32 or 64 pixels) in overlap area to increase the flexibility for accurate alignment between adjacent projectors. e Below figure is an example for [9x5 Curved] alignment in 1024 resolution: If the overlap is 256 pixels (25%) in XGA resolution, total adjusting points are 15. User will have less adjustment flexibility. If increasing two grids (64 pixels) to 320 overlap pixels, user can have 30 adjusting points to get more accurate geometry alignment. It can align the images from two projectors on curved screen with good quality without Gwarp PC Tool. i. Below is the list for the accuracy of geometry adjustment in different overlap pixels: GeoBox output resolution 1920*1080 1280*800 1024*768 Min. adjustment flexibility 240/480/720 320/480/640 256/384/512 Max. adjustment flexibility 352/608/832 224/256/384/416/544/576 192/320/448/576 4.5 Projector settings a Reset projector to default setting. b Disable dynamic color adjustment and DLP Brilliant color adjustment. c To disable Auto Alignment function if user wants to use VGA analog input signal to avoid image shift during projector switching ON/OFF process. d Disable Auto Keystone function. 8
e Select a Display Mode with 2.2 gamma curve will reduce the color difference in overlap area. User needs to test with different Display Mode setting based at final color fine-tune stage. f Use projector internal color adjusting function to adjustment the color variation among projectors before implement edge blending. g Install projectors at a place with image size that just can cover required image area and with minimize keystone to get better video quality. 4.6 GeoBox Settings a Reset GeoBox to default setting. b Select input port. c Select output resolution to be the same as projector native display resolution. d Check input/output LED indicators to make sure to have correction system connection. 4.7 Geometry alignment by OSD menu (use [4 CORN] & [WARP] hotkey) a Please be familiar with OSD operation from front panel and remote controller, including activate grid pattern, channel A/B switching and shortcut keys for [2x2], [Warp], [Video Wall], [Edge Blend] and [Info]. b [OSD Time Out] is default to 0. It will ensure the grid pattern will not be turned off automatically. Input mode change will disable OSD and grid pattern. c User can install IR extender receiver near each projector for easy GeoBox operation. If multiple units of GeoBox are used and IR receivers are put together, please set [Box ID] for each so that user can control each separately through [85x] command. Press number keys in Remote Controller following OSD menu for the control of multiple GeoBox: 850: simultaneous control for all GeoBox 851: control GeoBox ID No. 1 853: control GeoBox ID No. 3 d Use [Pattern] & [CH A/B] hot key to show grid patterns in all projectors. e Please follow the sequence [2x2] [3x3] [5x3] [9x5] to do geometry alignment. f Apply [2X2 Corner] geometry alignment and draw the corners to expected locations. g Apply [3x3 Curved] geometry alignment to do further corner, edge center points and center line position adjustment through 9 adjustment points. 9
h If user doesn t use Excel file to calculate the image size for each projector, please try to set the same projection height prior to geometry adjustment. In this case, the image width for all projectors will be also similar. i If user finds the grid size between adjacent projectors is different. It means the projection image sizes between two projectors are different. Please measure the difference and try to make them have the same dimensions. j Please use [5X3] & [9x5] for further geometry alignment and fine-tune. After finish the alignment, user can use [2x2] for complete image position fine tune. If user applied [3x3] alignment after [9x5] alignment, [9x5] grid position will be reset and only keep [3x3] grid points. k In ideal condition, all grids between two adjacent projectors should be overlap together. In some special case, the vertical lines in edge blending area have some gap and can t match 100%. User can adjust [Overlap] value in video wall settings to compensate this deviation and keep reasonable image quality. l After the above processes, if the grid pattern in edge blending area still can t stack together, then [Gwarp] PC tool should be applied. m Geometry alignment range from remote controller can be up to 300 pixels in [2x2] + 300 pixels more in [3x3] for one corner/edge. If more geometry alignment range is required, please use Gwarp PC tool to do geometry alignment. PC tool will double the alignment range. 4.8 [Video Wall] settings (use [V.WALL] hotkey) After geometry alignment, it is required to capture image for each projector. a Click [INFO] to check if correct input and output timing modes are set in the system. If no input signal or input signal resolution is not the same as Excel calculation, [Overlap] value in Video Wall setting will be wrong. b [Video wall] settings for three projector horizontal edge blending as example [Zoom]: all GeoBox set to H=3, V=1 [Pan]: LH projector (1 st ): H=1, Center projector (2 nd ): H=2, RH projector (3 rd ): H=3 [Overlap]: select the right edge and apply the value calculated from Excel file LH projector: RH edge, Center projector: both RH/LH edges, RH projector: LH edge For dual projector edge blending, user can use below equation to calculate overlap pixel. Assumption: Input signal:1080p, Output to projector: XGA, Overlap 224 pixels (7 grids) 10
Overlap value= (1920/2)/(1024-224/2)x(224/2)=118 pixels. User can also adjust [Overlap] value simultaneously and see the image in edge blending area comes closer till without double image. Two projectors shall have the same value. c If user still sees some blurred image in edge blending area, please increase or decrease [Overlap] value in [Video Wall] setting to improve video quality. If the adjusting value is more than 1, please divide this value for adjacent projectors. For example, if the value should be 2 in center projector LH edge, then please add 1 in RH edge of the 1st projector and 1 in 2nd projector LH edge. 4.9 [Edge Blend] setting (use [E.BLEND] hotkey) a Select correct Edge for the edge blending: LH projector: RH edge, Center projector: RH & LH edge, RH projector: LH edge b RED and GREEN color indicating lines will appear when increase edge blending pixels. c User needs to adjust the color indicating lines to match together (green to green, red to red) and will see the final result. 4.10 Overlap region gamma correction (under [Edge Blend] menu) a Please activate [Gamma] sub-menu under [Edge Blend], select [Transition] and change the [Gamma] value to get the optimized video quality. b [Gain] menu next to [Gamma] can do further gamma curve change in each projector. It is to do further edge blending area color fine-tune. User will see significant improvement when each projector has different gamma curve. c If there is still some color difference, please try to change projector Display Mode first. If it is still can t fix the issue, user can do further color adjustment in projectors or use [Color] sub-menu under [Edge Blend] menu to adjust individual projector color. 4.11 Black level uplift ( [Offset] adjustment under [Edge Blend] menu) a If the ambient light is dark, audience will see grey region in Edge Blending area. It is due to light leakage from projector optical system. Low contrast ratio projector will be more serious. Please apply [Offset] menu to uplift the color in non-transition area and [Corner] menu to do accurate position alignment. 11
b Under [Offset] menu, user can try [Gain] and [Offset] color compensation to let non-transition and edge blending area to have the same color as overlapped area. After this step, user will see grey bars near the borders of edge blending area. User can use [Corner] to eliminate these grey bars. 4.12 Final Image quality fine-tuning a The final performance will be a combination of many factors projector characteristics, projector setting, screen, ambient light and GeoBox setting. b Banding in overlap area under dark environment is caused by light leakage in the projector optic system. It is not possible to be fixed by signal manipulation. The only way is to raise the black level in none transition area through [Offset] menu. c GeoBox edge blending default setting is for projector with 2.2 gamma settings. To select projector display mode near 2.2 gamma setting will get the best result. d The projector may retain light leakage near the border of the imager (micro display DMD or LCD). It is not possible to be fixed. e The factors affect final image quality i. GeoBox settings: Edge Blending settings: Gamma, gain, Offset, Color Image Properties: To select Preset Mode to Neutral, srgb or Bluish Individual projector color adjustment [Color] function under [Edge Blend] menu. ii. Projector: To adjust image position of the projector and reduce keystone angle. Increase Overlap region & reduce off axis angle To change Display Mode, usually Standard, srgb/neutral will get better result. To disable projector Brilliant color adjustment or Dynamic color adjustment. Try different color settings in the projectors. iii. Screen: To use lower gain value screen. Short throw projectors with high gain screen will have color difference in different viewing angle and cause different overlap area banding from difference viewing angles. 4.13 System power ON/OFF setting a User can access [Options] [Accessibility] [Standby Time] to do automatic System Power ON/OFF setting by the control of signal source. 12
b If the time is set to 60, GeoBox will automatically turn off output signals when no input signal is detected for 60 seconds. c If the projector can also automatically shut down when no input signal is detected. User can control signal source to turn ON/OFF the system. d If the time is set to [Off], user needs to do manual Power ON/OFF in the system as default. 4.14 Enable [Black Screen] while no input signal or mode change a The default screen color when no input signal is detected or during input timing change is Blue. b User can set it into Black color by below OSD operations: [Options] [Accessibility] [Black Screen] [Enable]. 4.15 Save all settings into [Profile] [Index] a Activate [Options] [Settings] [Profile] [Save] to save the final settings. User can save up to 5 different display profiles. [Profile] menu will save/load two channel settings at the same time. b After finish all the procedures, please power off and power on the system again to check if the result is the same as expected without change. If any position shift is found, please check if Gwarp value had been properly download into GeoBox. c EDID settings in different input port will be also saved into [Profile] 4.16 Thermal drift in projector image position Projector will have some image position shift in different working temperature. Image position will be not stable at the first 15-30 minutes after power on. During this period, user many see some image position shift in overlap area. This is called thermal drift. Different projectors may have different phenomenon. The range for image thermal drift may be up to 5mm. 4.17 PC output resolution setting If PC is used as signal source for Microsoft Office, please select the right output resolution. Too high output resolution may cause blurred image in text. 1280x800 or 1366x768 output resolution is good for two projector edge blending system. 4.18 Possible issue in Edge blending with VGA signal a If PC VGA is used as signal source, please connect this PC during setup stage. In this case, GeoBox will automatically execute position auto-alignment while 1 st time connection and maintain the same without adjustment until new PC is connected or new PC timing is applied to GeoBox. After edge blending setup, please use the same signal source to avoid position shift. b If the projector is connected through VGA, user needs to use HDMI to VGA converter. Projector will execute automatic image position alignment. The 1 st automatic position alignment will be executed before GeoBox implement geometry alignment. After user finishes system setup, the image for projector will be changed. Once power on GeoBox or projector again, projector may execute position auto-alignment again and cause edge blending issue. c Please disable projector VGA input automatic alignment function to avoid image shift. 13
d If possible, please apply digital signals for both input and output in GeoBox. 5 Geometry alignment by Gwarp2 PC tool 5.1 System connection a Connect and PC via Micro USB cable. Gwarp2 is HID interface and no drive is required. b User can create different language for Gwarp2. c Open [Gwarp2.exe]. Click [Connect] to connect COM port. After connection, it will show input signal resolution and [Disconnect] icon. If unable to connect, please re-plug Micro USB cable in PC side or re-open Gwarp2 PC tool. d After connection, please select CH1 for RH channel and CH2 for LH channel for further operation. e Please download Gawrp2 PC tool and user guide from website at www.vnstw.com. 14
2 4 1 3 5 5.2 [Warp adjust] (hotkeys are available through keyboard and mouse) a Before [Warp Adjust] operation, please enable [Pattern] (1) and select one color and Enable the pattern to show grid pattern on the screen. The pattern default grid size is 32x32 pixels. b Select [Warp adjust], grid type and adjusting Step (2) (default is 8 pixels) for the adjustment. BLUE direction keys are for control point selection and RED direction keys are for value adjustment. c [2x2] alignment is for quick image corner alignment. Usually, user needs to apply [2x2] geometry alignment first to draw image 4 corners to the required positions, then go to [3x3] or [5x5] for further geometry alignment. After [5x5] or [9x9] alignment, if user want to re-adjust 4 corners position, user can go back to do [2x2] alignment. d For most of the applications, we propose to follow [2x2][3x3] [5x5][9x9][17x17] sequence for geometry alignment. Please note that if user executes [9x9] or [17x17] and back to [5x5], it will only keep data under [5x5] and reset all the rest. e For edge blending application, please align all the grids in edge blending area stacked together to ensure clear image can be obtained. 5.3 Save [Gwarp] result into GeoBox a User can save [Warp Adjust] result in PC through [Save setting] (4) and load back for further modification or copy to other channels. b After finish Gwarp alignment, please select the number and press [Save to Gwarp Pro] (3) to store [Warp Adjust] result into GeoBox. Please disable [Pattern] under [Warp Adjust] so that user can activate OSD menu in GeoBox. Keyboard [CTRL + P] will also close pattern and allow user to activate OSD menu. 15
c Manually activate OSD menu via remote controller and access to [Anyplace] [Gwarp Pro] menu and select the [UserMap #] to load Gwarp settings into. Channel A/B warp settings shall be loaded separately. e After finish geometry alignment, user needs to execute [Video wall] setting and [Edge Blend] in Gwarp2 or in GeoBox through remote controller to complete the whole edge blending process. f If PC tool is used, before save to Profile (5), user needs to save [Warp Adjust] and [Uniformity] adjustment into Gwarp Pro first. Otherwise the result will be not saved into Profile. User can recall Profile settings and modify in the future. However, modification in geometry result can only be done by [2x2 Corner] adjustment up to +_50 pixels in H&V directions. 6 Keyboard Hotkey for convenient Gwarp2 operation 6.1 System Reset [CTRL + Shift + R]: Reset selected channel [CTRL + Shift + A]: Reset all channels (from CH1-CH4) Input/Output resolution and Profile Index settings will remain the same without reset 6.2 [Warp Adjust] [M]: Change Adjust mode from [2x2] [3x3] [5x3] [5x5]...

User can also create any EDID timing through the menu [Custom]. The timing range are as follows: H: 1024-3840 V: 720-2400 17
d Some PC may not follow EDID from GeoBox and show different result. If it happens, please open resolution setting window and select desired output from PC. e User can also set non-vesa standard output timings from PC, GeoBox can accept this kind of output timing under the conditions that the maximum clock rate shall be under 330MHz and the resolution shall not exceed 3840x2400. 8 System bandwidth and system crash Due to hardware bandwidth limitation, it is possible to see some abnormal image during some settings. It is due to processing bandwidth limitation. It may happen in below conditions: 1. High resolution input source like 3840x2160 with different video wall ZOOM and Overlap settings. 2. When implement extreme geometry alignment. 3. When implement active 3D 120Hz input/output. 4. We suggest to select the image vertical resolution same as projector. If user uses 1280x800 projectors, then 3840x800 or 3840x1080 signal resolution should be selected to avoid the above bandwidth issue. 5. Once it happens, please reset the system and select different settings. Once it normally displays, no side effect will happen again. 9 Screen Selection a. Gain value less than 1.5 will be recommended for Edge Blending application. Higher gain value will be more sensitive to color difference among projectors. In short throw projector edge blending, viewer may see different edge blending result while viewing at different angles. b. Motorized screen position may be shifted from time to time. It will affect the image stacking in edge blending area and may cause blurred image. Fixed screen is recommended. c. If ultra-short throw ratio projector is used, the screen gain value should be under 1.00. The flatness of the screen will be also more important in this kind of projector. 10 Projector Selection and settings a. The projectors for the edge blending should be the same model and the same production lot. If they are not the same models, it may create some difficulty and performance issue. b. Usually, higher contrast ratio in the projector will have better black level performance. The projector with contrast ratio more than 3000:1 is recommended for edge blending. In a dark environment, video projector with 10,000:1 contrast ration or higher will be better. This contrast ratio should be native contrast ratio but not dynamic contrast ratio. c. If possible, please shut down Brilliant color and Dynamic auto color adjustments. They may affect edge blending result. d. All the projectors shall have the same setting including optical zoom ratio, color temperature, color characteristics, lamp setting, display mode...etc. e. Please select a display mode with the best performance. Usually, Standard or Native display mode will provide easier color fine tune. 18
f. Please select gamma 2.2 for edge blending. Different gamma settings and affect the video quality in overlap region. g. The mechanical stability in optical system is important. It should be rigid with less thermal drift. h. A projector with big ZOOM and lens shift will be more convenient for the installation. i. Throw ratio will affect installation distance, Please select right one based on the installation space. j. If ultra-short throw projector is used in curved screen, it will cause big image position shift and may also cause focus issue. Carpentry screen and curved screen are not recommended. 19
