Has anyone tried to drive two 4k screens with a 280X? I have a 5.1 with a non-flashed MSI R9 280X 3GB. It has two MiniDisplay ports. The Dell P2715Q is a $699 UHD monitor that checks these boxes: 60Hz IPS technology SST panel 99% sRGB and around 75% Adobe I'd probably default to a higher end monitor, but the price/performance ratio seems good here. And most reviews are positive. Nice way to save some money with a two monitor setup.
