This might just be an issue with the blurbuster ufo test www.testufo.com but I'm seeing stutter on this test where I shouldn't be. I've got a Rog Swift monitor running at 144hz and an HP ZR24W 60hz monitor on each side of it. If I leave the two ZR24W monitors unplugged from the graphics card (GT980) then the test works at 144hz with no stutter.
As soon as I connect the 60hz monitors, the test shows an awful stutter but it's not saying that on the test -- just valid. All 3 monitors are connected to the card's displayports. I've tried another GPU and isolated the Rog Swift from the other monitors with it and had the same issue so I don't think it's related to the GPU hardware.
If I change the colors from 32-bit (true color) to 16-bit (high color) on one of the 60hz monitors while the test is running, it'll immediately become buttery smooth at 144hz. One or both of the 60hz monitors can be set to 16-bit and all is well. Unfortunately, if you restart the test with a monitor in 16-bit color mode, the test will only go to 60hz. If you change the 60hz monitors to 32-bit color even after the test starts at 60hz, it'll then detect the higher refresh rate and do a 144hz test but again have the stutter. As soon as I change a monitor back to 16-bit, the test continues at 144hz and buttery smooth.
If I set the refresh rate of the Rog Swift to 120hz, I basically have the same results as 144hz documented above. The testing was done with Chrome.38.0.2125.111 m.
Anybody have a clue as to why this is happening? Is this a known issue with mixing refresh rates with Windows 7?
