Hi everyone,

This is one of four major issues I am having with the Intel G35 chipset in my Asus P5E-VM HDMI motherboard. I am using it in my HTPC.

Here is my setup. I am using all of the latest drivers and updates from the various manufacturers:

*** Hardware ***
Intel E8400 CPU
Asus P5E-VM HDMI motherboard w/ BIOS 0405 (2008/01/02)
OCZ 2x2GB DDR2-6400 SLI 5-4-4 memory
Aver PCIe Combo (R780) Media Center Upgrade (SDTV, ATSC/QAM, S-video inputs)
SMC 802.11a/b/g 108Mbps PCI wireless

*** Software ***
Windows XP SP2 + all updates (4/14/2008)
Intel Graphics Driver v6.14.10.4935 (3/20/2008)
Intel Chipset Driver v8.3.1.1009 (9/24/2007)
Realtek Audio Driver v1.90 (2008/3/31)
Aver R780 Driver v2.5.0.19 (10/03/2007)
Aver MediaCenter v1.6.1.2 (10/03/2007)
Epson Home Cinema 720p (1280x720 @ 60Hz)
Creative Inspire 7800 (7.1 speakers)


My desktop resolution resets from 1280x720 to 640x480 when I boot WinXP with display turned off. Happens every time, even when PC wakes from powersave while display is off (ex: bump mouse, PVR software kicks in). The only workaround is to turn on the display before booting or waking the PC. Since I am using the PC as a HTPC to drive a 720p projector, I cannot leave the display on. Projectors run hot, they use a lot of power (200W/230W), and bulbs have a limited life (2000/3000 hours).

Intel customer support's response was nonsensical. I think they tried to power cycle the display while the PC was still on. That is not the problem I described at all. :pt1cable:

Any help or information you can give me would be greatly appreciated.

Is this a known problem with the Intel Graphics Media Accelerator 3500 drivers? Is it a problem in the G35 chipset? Perhaps the problem is in Windows itself. I have no idea, but I really don't like the inconvenience of having to change my desktop resolution over and over again.

The EDID on your projector is supposed to work even when the power is off. Contact the projector people.

Or, go into the registry and disable all resolutions except 720p.
