R9 290 Eyefinity Screen Tearing
Hi guys,
Just having an issue with my eyefinity setup and wanted to know if there was a solution?
So first, my setup. I have an R9 290 connected to four screens. The first screen is a Dell monitor plugged into the first of the DVI outputs, and this is my PC desktop. I then have three identical screens plugged into the remaining outputs and connected via HDMI (one native, one converted from a DVI, and one converted from a displayport) and set up as a triple screen eyefinity group for gaming. I don't run them all at once, so when I am using my desktop I don't have the eyefinity group up, and when I amusing the eyefinity group, I don't have the desktop up (so a maximum of three screens running at any one time).
My issue is that on one of my eyefinity screens I get constant tearing about a third of the way up the screen at all times. I first noticed it gaming, but it is very repeatable with just the windows desktop running. The other two identical displays in the eyefinity group are fine, and oddly enough the display exhibiting tearing is the one plugged in to the native HDMI rather than converted.
I thought that the 290 cards had three hardware screen clocks and shouldn't have timing issues with multiple displays. Can this be solved? Is one of the clocks shared between two outputs so that if I jiggle my connectors about I can have three happy screens at once, is there some CCC setting that I can play with to remedy the tearing, or is the only solution to spend £80 on a displayport hub (to get functionality which the card should have out of the box) and run the eyefinity group from this?
I previously had a 7970 which needed active displayport dongles to make this work, which whilst a minor annoyance was at least reasonably cheap to solve.
