so i just built a new pc because i couldnt figure out what makes the bad display in my old rig.
other then the psu, (formated)ssd and 16 g 2666mhz ram every thing else is brand new and i have the same display problem.
the monitor works fine on my laptop with the same hdmi caple and i have the same issue on 2 different monitors.
