I recently purchased a stock 7970, and decided to hook up my HDTV as well as a monitor. When in single display mode, my temps run at 40C idle, voltage is 800mV, and the core clock is 300 mhz.
When selecting duplicate displays, the clock goes to 500 mhz, voltage to 1150 mv, and temps to 60C. All of this is idle at the desktop. No overclocking. I haven't tried gaming with the displays dupicated, but I have no issues when gaming in single display mode.
This seems very abnormal. Nothing like this happened with my old GTX 570. Both displays at 1080p and running at their native rez. How should I proceed? Is this a hardware error? Driver error? BIOS? I really don't have much experience with diagnosing video card issues, and none with AMD cards. I'm used to them just working
Any help is appreciated
