[Note, I'm not an AMD engineer.] In some monitors, such high modes are actually exposed by presenting multiple "tiles" as separate screens. As far as the GPU is concerned, it's 2 actual monitors (this can only work with DisplayPort, of course). Can you check if this is the case? I believe "xrandr" should report 2 separate monitors in this situation. You mention you have a 49WL95C-W, which the internet suggests is indeed just 2 panels placed next to each other in a nice plastic case. And in such cases, I believe the AMD drivers clock to the highest rate, since reclocks will cause flickering (since the vsync's of the 2 monitors aren't sync'd to one another). -- You are receiving this mail because: You are the assignee for the bug.
