Alright. I am currently having a problem with my new AOC FreeSync display. I have two displays connected to my computer, one is my new AOC monitor (1920x1080 @ 144Hz on display port) and the other is a Sanyo 50" LED TV (1920x1080 @ 60Hz on HDMI) I like to have movies or shows playing on the TV while I play games on the monitor. Windows does NOT like this. I have read many, many, MANY posts and such from both ATI (which I have) and NVidia users describing the same issue I am getting. When you use multiple monitors with differing refresh rates, you get horrible stuttering on one or both monitors. Apparently this is due to WDM (Windows Desktop Manager) and some application of VSync to the desktop. IE whenever you have two displays with different refresh rates connected and something is moving (a video, dragging a window around, etc) with WDM/Aero enabled you will get horrible stuttering. Before I got my new monitor, I was using a standard 1080P 60Hz monitor and therefore did not get the issue because the refresh rates were matched, but as soon as I got the new monitor hooked up I started getting stuttering.
There are a few "fixes" around but they are not 100%. Most dont work for everyone, some only help a little bit and some introduce more issues. There apparently was a registry edit that fixed it completely, but it was for pre-service pack 1 and those values have since moved (and I cannot find them). The only thing that has helped so far was to disable aero entirely, and therefore the VSync, but unfortunately that makes any video tear horribly, along with just generally making the desktop look crappy (weird visual errors when dragging windows around and stuff like that). I have done hours of searching and so far I cannot find any other "fixes".
The only two options I can find at this time would be to either buy a second (cheap) graphics card and run my main display off my good one (an ASUS Radeon R290X) and run the TV off the second one, but this may introduce more issues, even buying another ATI card its always possible to get driver conflictions and stuff like that. Or I could set my main display to 60Hz in the display settings, but it seems a waste to have a 144Hz monitor running at 60Hz. Unless the FreeSync properties of the monitor/video card will override this, and that is my question. If I do set my display to 60Hz in the monitor settings, will the FreeSync feature override this when I am playing a game? It SEEMS to me that it might, depending on how FreeSync and the graphics card drivers operate. If the FreeSync portion of the drivers bypasses the set refresh rate in the settings, and I imagine this could easily be the case (since it cant really have a "set" refresh rate for FreeSync to work), then it wouldnt be a problem. But it could also be the case where the "set" refresh rate in the settings ends up being a "maximum" that applies to FreeSync as well.
So if anyone could weigh in on this I would appreciate it.
For the record my system specs are as follows:
Windows 7 Ultimate x64
MSI Gaming 970 motherboard
AMD FX-8320 x64 8-core @4.0 GHz
16GB Patriot Viper DDR3 2400
ASUS Radeon R9 290X
1000W power supply
120GB SSD for Windows, 480GB SSD for games/programs and a 3TB HDD for storage
