I have a x850 XT with the current catalyst control center and drivers. My TV is a Panasonic TH-42PX80U.


I have a DVI to HDMI cable (25ft) going from my DVI port to my TV's HDMI port. Whenever I turn on the TV and the cable is connected and resolution / monitor enabled I get a no signal found error. But when I turn on the display and then enable my second monitor with the same resolution settings the display works correctly!


It is a pain to have to manually enable the monitor every time I want to use the TV. I have not been able to figure this out for a while and am last posting here for someone to hopefully have had this problem before / know what is going on.


The resolutions I use do not matter, it happens for all of them. The TV works fine on that port with a xbox 360 its just this computer that has the problem.

Are you using clone mode or extended desktop mode for the two displays?

Which display is set as the Primary Display?

What is the resolution setting of the second monitor?

I finally found out what is happening. It is a problem with ATI's drivers that is still not fixed (even though they said they did)


Here is a workaround for anyone interested or has this problem. Seems like it is only the older generations that have it.
