Hey guys, I recently got a brand new Acer XF240H (144hz, FreeSync), and I'm having problems when using Display Port. The image will jitter, and often flicker on and off. Im running two R9 290x, but I've tried using the other GPU, swapping GPU in PCI slots, tried two different DP cables, and still no improvement. I have also noticed that any refresh rate, 30, 60, 120, 144, all will have the same problems. Display drivers are up to date as well.
When I use a DVI cable, the maximum refresh is 120hz, but there is no FreeSync capability. However, the image is perfectly good and the monitor seems to work just fine. Thats nice and all, but I really want to get freesync capability as well.
I have also tried using the monitor on my roommate's pc. He has an Nvidia GPU, but regardless, his rig doesnt show ANY of the problems that I'm having when using display port, so that kind of eliminates the monitor/cables being the source of the problems.
