1280 x 800 via HDMI possible?
My projector is native 1280 x 800 but 3d doesnt work in it (red message).

Is this a limitation of HDMI, or is there a way arround it. it has no DVI input. (its an optoma GT720)

Cant help but feel like im wasting the projectors full potential by having it at 720p...

thanks!

Some say yes, you should search 1280x800. May require inf. hack, I think its locked by nvidia and optoma for quality reasons. The pj may not be able to display 800p 3d fast enough, resulting in ghosting at top or bottom.

Considering they build in a little extra room for extraneous data of some sort into the frame packing template, seems like it should be possible.

Currently there are 2 projectors on the Nvidia 3D Vision requirement list that are capable of 1280x800. The NP-V300X and the NEC NP-V300W http://www.nvidia.com/object/3d-vision-system-requirements.html

That site shows the gt720 as being 800*600 which it isn't...

Probably was a data entry error or an error with the submitted EDID. You can always submit a new EDID.

The NP-V300X is native 1024x768 according to NEC's own site. The NEC NP-V300W does list as 1280x800 though.

If your DLP chip is the same as the NEC NP-V300W, you could obtain an .inf file from one and could probably do an EDID override. I agree, unused resolution going to waste is a bummer. I played for a short while in 1280x800 but was plagued by the warning as well. I've heard you can change the overlay color to something a little more transparent/annoying. Unfortuneately EDIDs have been suppressing resolutions worldwide since their inception, as well as being the source of a whole slew of video/audio problems.
