Extended display is grey after update

Hey, i was wondering if anyone here could help me with a problem. I have my computer hooked up to a 24" gaming monitor, and a 60" TV. It all worked great until i installed a update today, and now my TV has a grey color when i use both screens.

If i just use my TV it has the correct colors, but if i try to use extended or duplicate it get a really grey hue, while my gaming monitor works fine.

I tried updating my graphics driver, but it didnt fix anything.

Any tips i could try would be greatly appreciated.
