Losing colours when changing resolution

scouser_jmc · 9 Mar 2019 at 18:54

Hi everyone,

I'm having some problems that I've been unable to solve myself and I'm hoping for some advice!

I've got my pc hooked up to my TV, everything looks great at 4k, but if I change the resolution to anything but 4k all my colours get messed up. They're mostly purples.
Anyone come across anything like this before?

I guess it looks like in this case?

Anyway use GPU scaling instead of TV's scaling if you don't want to use native resolution.

Thanks for the reply!!

Gave that a try but no luck

I have no option to select gpu scaling, just display scaling

After playing with settings it seems to be that the tv is fine at 4K and 60hz
But any other resolution has to be on 30hz.
The tv supports 1080p at 60hz according to the manual, and I’m sure that’s what my PS4 uses, so I don’t know why the tv won’t get the colours right from the pc?
Iv tried different hdmi cables and different ports with no luck

GPU scaling is selected in graphics card's control panel.

Thanks for the link, but the options missing from my drop down box. I can only select "Display"
:confused:

AMD's control panel should allow selecting option always, but if you have Nvidia not sure if that option is selectable when having native resolution selected.
