Page 34: Edge Blend]
G-700 a、 [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, it is enough for most of the curved screen edge blending. -

Click [Save file] will save the file into PC and need to use press [Load file] to load back settings. Click the # under [Save to Gwarp Pro] will save Gwarp result into G-700. User can create up to 10 different Gwarp results into GeoBox. - Page 44 [OSD Time Out] is default to ”0”. It will ensure the grid pattern will not be turned off automatically. If multiple units of GeoBox are used and IR receivers are put together, please set [Box ID] for each G-700 so that user can control each G-700 separately.
- Page 45 G-700 Select channel and use [Pattern] hot key to show grid patterns in all projectors with different color for easy alignment. Apply [2X2 Corner] geometry alignment and draw the corners to expected locations. Please make sure the image size in all projectors should be similar. Otherwise, user can’t align the grid patterns on the overlapped area correctly.
- Page 46 For dual projector edge blending, user can use below equation to calculate overlap pixel. Assumption: Input signal:1080p, G-700 output to projector: XGA, Overlap 224 pixels (7 grids) Overlap value= 1920/(1024x2-224)x(224/2)=118 pixels. 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.
