they are both 4th gen gcn so there should be little to no difference in graphic output
other than the fps each card can spit out.
from what i can see they are basically the same card with bits lopped off the 470 to reduce price.
so i would think its likely a new cable, or your amd gfx control panel has changed the defaults.
if not maybe some other system process that dimmed the screen is no longer active after the card swap.
Are you using the same HDMI/Display port on your monitor? Most monitors have per-input brightness/contrast settings, so this is my guess. Otherwise try resetting your screen and GPU settings to default. If you’re using linux try using a live USB to check colours there.
This - I mostly own nVidia cards so it doesn’t translate directly, but I’ve had multiple instances of changing either a monitor or video card and this box in the control panel sets itself to limited dynamic range:
It wouldn’t surprise me at all if AMD has a similar option buried somewhere in their control panel and you’ve been in some kind of reduced dynamic range mode this whole time.
I’ve been busy with new job, and haven’t had time to check this post. But good information to know.
I definitely am not complaining, but it just seemed odd to me. I guess I wasn’t getting the full potential of my graphics quality before the swap. Everything is much brighter, and clearer. So no complaints here.
I doubt it, but it could be possible. I did not move the monitor when hooking up new graphics card. But when I set it up originally, i could have, and now the monitor is on it’s default settings maybe? All I know, is it looks great, and I am happy.
