This affects me too. I have a Radeon HD 7970/8970 OEM / R9 280X and the display is a Samsung U28D590D. Using an HDMI cable works perfectly. Using DisplayPort makes the display be disconnected when light-locker kicks in. I have to manually reconfigure the display until it shows me images again. I do notice that the display receives some sort of signal when I active my computer. But it shows no image and then goes back to idle.
I have a seconday monitor connected via DVI and that monitor keeps working perfectly.
