Using TV

[dan958]

Hi,

Everything runs fine normally. I have a HD 7870 connected to my monitor using DVI. I recently decided to connect my tv to the HDMI so I can game with a controller a little more comfortably (with rpg's and games that are awkward with M&k)

I have the antec cooling for my GPU but I find once I turn my TV on, even at idle it reaches just over 60 degrees.

Is this normal? Without the tv plugged in it gets just above that at full load.

Do you have both the game on your monitor and TV at the same time?

No, extending the display - not duplicating.

When you go from 1 screen to 2 attached to your 7870, the card cannot drop as far on idle. If you check CCC, GPUz, or any other monitoring tool, you'll find your core will idle higher (probably 500 rather than 150 with 1 screen) and your RAM won't downclock at all. This is by design and is to stop people having issues when running two (or more) screens, and is to do with the card having to produce 2 (or more) signals so it won't matter if the second screen is extended or duplicated.

Easiest way to see this is to open CCC, check the clocks in Overdrive, then disable one screen and check them again - you should see the clocks and temperature drop when disabling the second screen.

So are you saying that if I want to game on my TV, I should just disable my monitor?

Okay. Since I mentioned this problem, it seems to be running ok now. The idle temp with dual monitors is a little hotter than usual, but that's expected. But it doesn't reach he very high temp that it did before, maybe the fans auto speed wasnt working properly and was fixed on a reboot - who knows!

Thanks for the help
