First time using multi monitors
I'm just dipping a toe into multi-monitor use and have some questions. I have a 24 inch, and a 17 inch monitor at the moment (have another 17 and 19 to use if need be later) I have a 5870 ATI card. I have both monitors plugged into the video card. I've noticed when I extend the desktop to both screens I have some "flickering" on the second 17 inch monitor. Almost like its trying to adjust itself to something automatically. It only flickers when I scroll the mouse wheel up and down a page or move a window around, etc. Seems to happen when one screen has a browser at full screen and something might be leaking over to the other screen, not sure if I can explain it better than that. When I create an eyefinity group even though the monitors are different I see no flickering at all, all is well. Just wondering if this is some setting on the smaller monitor I need to look into? Its a Dell 1704FPV. ALSO, I am assuming this videocard with two monitors on it may take a performance hit if I use it while gaming? For example have the 24 inch be the gamer monitor and have the 17 inch showing the desktop with a browser window, or teamspeak on it? Also, I'm looking through my parts here and I have some older video cards I may look into adding one just for the second monitor on the desktop. Thoughts?

Hi, This should be a setting issue, based on my experience, you could try the following methods to check if you can get rid of it: Try to update the graphics drivers. You should download them from the official websites.Update the BIOS to the latest version.Correct refresh rate, try to set the largest refresh rate: http://windows.microsoft.com/en-us/windows7/Correct-monitor-flicker-refresh-rate Alex Zhao TechNet Subscriber Support If you are TechNet Subscription user and have any feedback on our support quality, please send your feedback here.Alex Zhao TechNet Community Support

I turned off the overdrive feature on the ati video card and that stopped the issue. I found a youtube video of the same issue and it was exactly what was happening on my side.
