I am a newcomer to these forums, but I am sort of fan of 3D format, using DLP projectors dating back more than five years. But the bad PC 3D support, crappy Nvidia 3D vision implementation + paywall, low resolution, high input lag, convergence issues, never did it for me. Since the complete removal of 3D vision from 3D drivers I thought all hope is lost! However, the introduction of Geo-11 rekindled my interest, and here I would congratulate the developers for the amazing work!
I am a little bit tech savvy, and I thought maybe I can contribute something worth for the discussion that will make 3D more accessible: I want ask the developers of Geo-11 to add native support for the (hdmi) frame packed 3D protocol. At first glance this seems awfully complicated, but after some testing; I came up with a solution that it can be done without 3D vision completely! It will work on any GPU, plus a compatible HDMI device given proper Geo-11 support. Here come the details.
Step One: The user must set a custom resolution that confirm to the frame packed specifications, either through the graphics control panel or through the Custom Resolution Utility (CRU). Frame packed protocol as it turns out is nothing else than special a full top-bottom 3D mode with a blank space between the pictures. Here are the specs (https://etmriwi.home.xs4all.nl/forum/hd ... action.pdf) :
frame_packed_720p : resolution 1280x1470, 60Hz
- horizontal: 1280 active; 110 front, 40 sync, 220 back (1650 total)
vertical: 1470 active; 5 front, 5 sync, 20 back (1500 total)
- horizontal: 1920 active; 638 front, 44 sync, 148 back (2750 total)
vertical: 2205 active; 4 front, 5 sync, 36 back (2250 total)
- After you set these and your device accepts them; they you most likely be able to enable frame packed mode if your device supports the feature.
- I have couple projectors, I was able to get 3D with above custom resolutions:
- Benq W1400 (old hdmi 1.4a projector), 1280x720p@60Hz frame packed, 1920x1080@24Hz frame packed
Acer GM550 (1080p 120Hz projector), 1280x720p@60Hz frame packed, 1920x1080@60Hz frame packed
Benq W1720 (faux-4K projector), 1280x720p@60Hz frame packed, 1920x1080@60Hz frame packed, 1920x2160@60Hz top-bottom.
Step Two: Geo-11 should add native support for the above resolutions, however, Geo-11 only needs to enforce the screen resolution, doesn't need to know the rest. The proper HDMI signal is handled by the video driver via the custom resolution above.
frame_packed_720p : force screen resolution 1280x1470; scale the left and right images to 1280x720. The put the left image on top, then a 30 pixel tall blank space, then put the right image on the bottom.
frame_packed_1080p : force screen resolution 1920x2205; scale the left and right images to 1920x1080. The put the left image on top, then a 45 pixel tall blank space, then put the right image on the bottom.
That's it, it is basically top-bottom full mode. However I want to emphasize that the scaling of the game's resolution to 720p/1080p is a necessity to take advantage to supersampling AA. I think Geo-11 and 3Dmigoto have the capability to do this.
Then after these have been done, 3D gaming steps could be:
0. Set 1280x1470 custom resolution in the graphics drivers (once).
1. Install a DX11 Game and its HelixMod fixes.
2. Install Geo-11 and select direct_mode = frame_packed_720p or something like it.
3. Launch the game. Enable 3D on the projector/device. You get 720p frame packed 3D.
Then, first time like ever, 720p/1080p frame packed 3D gaming just work, universally.
