I'm using a 570 with extended display just fine. It flickers when I open a game, but goews back to normal quickly.

Seems fine on extended display its just on clone mode have u tried it through clone yourself

I thought this was going to be a thread about fermi cooking the inside of your pc when you hook 2 monitors up.

Not tried cloned myself.. don't want to lose my desktop shortcut arrangements sorry.

Nah lol think was only only 400 series that did that temps are fine

Well not genuinely cook, but with 2 screens plugged in my 580 jumps from mid 30s idle to high 40s idle. -__-!

When something like this is happening. Its normally to do with overclocking and v-sync. Or maybe your refresh rates are set differently on each monitor.

Yeah that prob happens we all cards yeah mine does we me gtx 590

I made sure that they both on same refresh one is a led full hd tv set through hdmi and my monitor is a full led monitor through dvi I already looked into if that was a problem

Why would you want to run surround with 2 monitors?

Bezel in the middle would not work well....

Just to test

To all.

When you put a second monitor onto a 4/5 series Nvidia it automatically goes under full load. Meaning, your adaptive performance stops working and there's nothing you can do about it as it's intentional.

Basically Nvidia cards can not drive two monitors whilst down clocked. So you're stuck with it.

It should !

I nearly returned my 470 because I thought it was faulty.

Common issue, no fix.

According to EVGA OC Scanner it drops to have clock speed when idling, is that what you're referring to?

Got a monitor in HDMI and DVI-VGA

Yes, adaptive performance. If you connect two monitors it has to remain at 100% clock and a load put on to stop the screens from flickering.

That's strange, hasn't happened on mine!

Maybe it is different on the 460 then? I know for sure that it definitely applies to the 470, 480, 570 and 580.

That's fair enough, not something I'd heard before that's all. I really like that modern stuff will downclock when idle, makes a lot of sense. I wonder why they can't with 2 screens, hopefully this isn't an issue that future ones will have.
