Flickering in Witcher 3

So im playing witcher 3 in 4k matte for several days now and im experiencing flickering. I dont know if its the game or the monitor. Sometimes monitor become black and after one second it reappers again. Is this an issue? cause i never experienced it before with my other previous monitors

Issue has been documented extensively. Are you using G-Sync and have you you updated to the latest firmware version?
