long time lurker first post lol i work on a 4K screen next to a 1080p one all day, and today was unbearable. flicker, flicker, flicker on teh secondary screen.

The Mobility Catalyst Display Drivers 11.3 Vista/7 32-bit update went in last night. Ive tried swapping DisplayPort and HDMI and moving the monitors to different outputs. The primary screen stays perfect. Can a driver realy do this to just one screen?? The flicker is subtle enough that I sometimes doubt myself, then it happens three times in a row and I wanna throw the monitor across the room ;) Any ideas on what to test first? im about to throw this thing out the window lol
