120HZ 3D Over Long Run HDMI - Loses Resolution when Full Screen Optoma HD65
I got the HD65's 3D to work with 3DVision after using the Acer inf and it looks awesome. The 120HZ signal works great when the HD65 is plugged into my PC directly via VGA; however, it isn't working over HDMI in full screen. I can get the 3d to work in Stereoscopic player non-full screen, but I lose 3d and the signal goes down to a crazy resolution (1024x768 at 75HZ or something like that) when I enable full screen in any game, stereoscopic player, or TMT. My original thought was that there is insufficient bandwidth in the HDMI cable, but I know it can carry a 1080p signal when I tried out an Optoma HD20 1080P projector - I'd think the bandwidth of 720p 120hz would be right around the bandwidth of 1080p. I did the whole home theater install in November 2010, a 45 foot hidden 22AWG Monoprice is carrying the signal from the projector to the wall plate and another 6 ft hdmi cable goes directly to my GT240's HDMI input (bypasses my Onkyo 806 Receiver). Can anyone confirm/deny that it's the long run HDMI that's doing it? Maybe it's just a driver issue? I can just go with a long run vga cable from the HD65 to PC, but it's ceiling mounted and requires a lot of moving around the PC to do so and kills the whole point of hiding the wires. Any help would be appreciated. Thanks everybody!

Sorry - I'm using the Optoma HD65, which is a 720p 120hz projector. I just mentioned the 1080P projector to give an idea of how bandwidth my cable is pulling - sorry.

if i'm not mistaken 1080p 120hz can only be obtained with Dual-Link DVI if you try to use that with hdmi it will not work.
1080p 3D only works in HDMI at 24hz if i'm not mistaken...

You are completely correct, It was a shame too because I wanted to try my computer on my 120Hz TV to see true 120FPS but alas HDMI fails again and it could only push 60Hz...
Why can't more TVs have DL-DVI? /wallbash.gif' class='bbc_emoticon' alt=':wallbash:' />
EDIT: How long is this HDMI cable, I have run into issues in the past with long HDMI cables only able to push small resolutions with low Hz rates due to slow bandwidth limitations of HDMI.
EDIT2: Wow I am just not reading well today, yeah I can say that the first HDMI cable is too long to push the proper resolution + Hz rate you desire and the extra 6foot cable to connect to the video card is most likely adding another bandwidth bottleneck. As you even said, the VGA works fine so it is not a videocard/driver issue, just HDMI limitations.

The cable is a 40 or 45 foot HDMI cable. I got the thickest and best available at the time from Monoprice (22 AWG); this was in November 2010, so I think it was before the advent of High Speed/HDMI 1.4, etc.

Oops - missed that second edit. That makes sense - I'll try a 3 footer instead of the 6 footer and see how that works. Every little bit counts! Either that or rewire the HDMI through the ceiling... Thanks for the help and I'll let you know how it turns out.
