Hi
About a year ago i bought a U28E590 4K monitor. after a few days when i turned it on it would just flash a black screen and the power light would blink (This does not happen in HDMI mode). Also after about an hour when i am playing games the monitor drops back to desktop. I have a stock HP Pavilion with a 600w PSU and a NVidia 980 GTX GPU

Hey @Choccyshop.
Have you tried a different cable and reset the Monitor? If these steps have been taken, it would be best to get in touch with the manufacturer of your PC - they'll be able to run through some diagnostics with you.
