DVI Problems with TV ATI cards (9800)

Athfar · #1 08-03-2005, 12:36 PM

I'm sure that most ATI card do the following:

When using the DVI output on my 9800 Pro & turn my TV off it seems to give up on emitting the DVI signal until I change my resolution again (using remote desktop). So everytime I want to turn my TV off I have to RD into my computer & change the resolution back and forth to make it use DVI again.

Anyone know a fix for this or can redirect me to the right thread?

Thanks,
Chris

I have the same setup. I found that if you turn off any screensaver or monitor blanking timeouts in windows, the signal doesn't drop/

I've gone through all the power/screen saver stuff in sage & windows and its all disabled. I just tested that it does it when I simply turn the TV off and then back on. Once I do that the DVI signal just drops.

As far as your setup you are using the DVI dongle, which may effect the "staying on" of the DVI signal. I am plugging straight into a Samsung DVI on the 46" DLP.

What is your catalyst driver version?

I have an ATI 9600 Pro connected to a Sammy DLP via straight DVI and I have never had this happen to me. Whether the TV is on or off Windows or Sage first goes to a screensaver then blanks the video signal. Moving the mouse or pressing a key brings me back to Sage or the Windows desktop depending.

I'm not sure why your resolution changes when the TV is turned off but it shouldn't act like that.

The res doesnt change, but i have to change the resolution to something else and then back to the original after I turn the TV off to get the DVI to work again.

I'm thinking its something to do with the drivers.

I'm going to time it and find out how long it takes to actually stop emitting signal... because i can turn it off/on quickly. I'll post the time and maybe it will answer something

It takes it probably around 2-3 mins to drop the dvi signal and its not a screensaver or power option because im using Radmin and moving the mouse and its not getting a signal.

It in fact has something to do with the drivers that causes the DVI to time out. I'm using the newest 5.7 catalyst (without the CP or whatever other garbage ati give you).

I'll give the omega drivers a try, let me know what versions you two are running so I can download them.

Yea its the catalyst 5.7 drivers that screw it up...

Thanks
