Are you using an ATI card?

This sounds like the issue where in 2D mode, the drivers drop the clocks too low to handle 2 monitors. You might want to try the latest Catalyst drivers. It usually never happens unless you use the Catalyst Overdrive options. You could fix it by simply turning that off most the time. The newer drivers may have fixed this as well.

im using a5830 and yes i use over drive to over clock the card. this happen on my 4870 as well. i updated to the lastest drivers. whats do i need to change to stop it?

I remember 10.9 drivers fixed this, even with overdrive working. Or maybe it was 10.8. However, other than that set of drivers, the only fix was to disable Overdrive.

how do i disable over drive?

There is a checkbox at the top of the Overdrive area. I'm no longer using that card, so I can't tell you the exact name of the box.

If you lock it, then hit apply at the bottom of the tab, that should disable overdrive.

If you look at the bottom of the tab, it should show your clocks, if the memory clocks is below 900, we are on the right track, but if it's over 900, your problems may be something else.

i have my clocks at 850 1100 and its stable in gpuid it shows the right clocks but in over drive it shows 400 by 800

ya, that would be helpful. And if you could, just make it a link, so I can see it full sized.

Btw, what is the frequency of the flickering? If it just happens once in a while, then unfortunately, I never could resolve that. If it's the horrible out of control flickering on 1 monitor only, then I can help you.

The once a few minute flickering is the reason I no longer use an ATi card.

im working on the screen shot now. the flickering gets really horrible when i play a game or watch a movie. it varies between screens. sometimes it will be on the full screen sometimes the wide screen. the other night it was so bad i had to stop everything it was jsut randoly happening while i was brosing the web. it does it every 3-5 seconds

Ya, this has to do with the low power mode and memory clocks. Turning off Overdrive seemed to fix it for most drivers. You may want to try installing a different set of drivers if this doesn't fix it. I believe 10.9 or 10.8 fixed it. 10.3 worked with overdrive locked.

Edit: with it locked

i jsut reinstalled ati drivers

The check box I was refering to is just below the Lock button. It says, "Enable ATI Overdrive". You just have to uncheck that box and apply.

The unlock button is a one time use button.

Your memory clocks are in lower power state, and is the same problem I had. Unchecking the "enable ATI Overdrive" button should fix it.

If you do want to use Overdrive, you could try an older set of drivers, I believe 10.9 (+ or - 1) allowed me to use overdrive, and keep the higher memory clocks. In fact, someone earlier was having issues with his 10.10 drivers doing that, even with 1 monitor, and installing 10.11 fixed his issue. That may also mean 10.10 would allow you to use ATI Overdrive and have the higher memory clock.
