Odd video and gaming display problem

[dancingmatt]

Hi all

Plugged my new rig into my 1280x720 Sanyo Z3 projector last night. I've got a 7900GX2 (the massive dual card precursor to the 7950GX2, identical in all but size) and I'm running Win XP MCE and nVidia 91.45 drivers.

I can't run any games on the projector in the native resolution - for example, Medieval II Total War only displays the top 30-40% of the logo screen during loading, and eventually the hourglass freezes and I can't do anything but press the reset button.

I also can't play any DVD films from my hard drive in PowerDVD v6, again I only get the top 30-40% of the film. The bottom majority of the screen is black. I worked through the Media Centre display calibration video and had similar problems, although on the first video file it started off displaying the fullscreen, and then gradually, about 10 pixels at a time, lines disappeared from the bottom. For all the other files I can't see any of the bottom 60-70%. I can, however, play WMV HD files in WMP.

Never had a problem with any of these video files or video playback in 1024x768 on my little monitor, nor had a problem playing games or DVD files on the projector in 1280x720 from my old PC.

Is this a driver issue? Is there some problem with widescreen? In summary when playing games, DVD .VOB files or the MCE calibration video, the bottom majority of my screen vertically is black.



Hope you can help, ta

Well, Ok, we can try. Is your monitor capable of displaying the 1280 resolution? if so, does the problem persist on the monitor? If not, then theres nothing wrong with the system and the problem lies with the projector.

Is the cable you use a Known good cable? try swapping the vga cable with another one, just to confirm.

Have you tried the projector at 1024 * 768 resolution?

is the projector setup to display 1280, if it doesn't re-adjust itself automatically.

Just trying to get the bigger picture, cheers!
