im relatively embarrassed to say i can't fix this. i've no idea where to start, its just something i've never seen before.
so ive got a decent nvidia card and a dell 28" 4k display. so decent enough kit. both less than a year old.
ive got the following colours on the homepage, absolutely no red in there to my untrained eyes. and i can't work out if i've set it or if its an actual failing conponent.
ive looked in display, i've looked in color management, ive reset the settings on the monitor.
is there anywhere else to look?
should add windows 8.1 up to date, latest nvidia drivers.
