Keep Getting Blank Screen... Resolution Resetting?

608 Views 2 Replies 2 Participants Last post by  amadeus00
I have been experiencing a very annoying problem. My HTPC is hooked up to my Toshiba HDTV via component cables (no DVI or HDMI). The HTPC is always on and no standby mode, just 'Turn off monitor' after 5min in the power setting. Everynight, something happens and when I go turn on the TV, the screen is blank. The computer is working as you can use hot key to turn off the computer. It seem like the resolution is resetting itself to something the TV can't use. On top of that, I tried to trouble shoot by hooking my LCD as a clone display but it can't recognise the resolution either! The only way I can get things back is to boot in safe mode and do a system recovery to the last time I was able to watch TV. Any ideas what's going on? No driver updates, just the usual MS and virus scan updates.

Well, I'm no expert, but I'll share something I just learned about my new display. It is a DLP projector (720 X 1280 native), and I feed it with an HTPC. After closely reading my user manual, I learned that there is a plug-and-play standard called "VESA" with certain resolutions supported by the projector. This is a way for the PC and PJ to communicate and sync up with one another without the need for extensive trial and error in setting a proper resolution. My manual lists numerous resolutions that have VESA support. The thing is...and I quote: "For VESA plug-and-play to function properly, the projector must be turned on before the computer." I'm not sure whether this operational sequence is mandatory for VESA, or if this is just how the manufacturer of my display chose to implement the function.

Anyway, I was thinking that this sort of thing might apply to your situation. Since your HTPC is always on, the display device would never be turned on first. Of course, this whole issue may have nothing to do with your problem, but I thought I'd mention it just in case. :)

I am still plagued with this problem. I've tried different drivers and the results are the same. Sometimes I can go a couple of day without getting the blank screen and sometimes I get them everyday. Anyone have any idea what might be causing this?
