    I connected my Dell Optiplex 745 running Vista Business to my HDTV using the VGA output from the onboard video drivers, Intel(R) Q965/Q963 Express Chipset Family, through a VGA to HCMI converter box and am using the 1280x720 85 hz. setting. Everything is good when I get it set, but here's my problem. I have to setup the video mode by plugging the computer into a monitor and then switching the output through the converter box to the HCTV, which is considered a non-Plug and Play device. When the computer reboots for whatever reason, the video chipset sees a non-PnP monitor and goes into a display mode that the HDTV says is unsupported. According to the Intel site 1280x720 display mode is not a "static display mode":

    Static modes for non Plug and Play monitors without an EDID. The set of basic static display modes (at 60Hz and up to 32bpp colors) include 640x480, 800x600, 1024x768, 1280x1024, and 1600x1200.

    Is there anyway that I can program or "lock" the display mode so that the computer will always boot with the 1280x720 display mode?
