Heya guys, I just bought a 4k screen off my friend for 350 quid. I couldnt past the offer so I went ahead and bought it. Now I already see something thats insanely annoying me and am not sure if its the pannel or if its ment to be like that because if thats a feature its going back 
Monitor Model: U28D590
Monitor Id: SAM0B80
Native Mode: 3840 x 2160(p) (59.997Hz)
Samsung U28D590 28" 4K 60Hz 1ms Gaming Widescreen LED Monitor - Black **OcUK Exclusive**
So, Everytime I play a game, As soon as you move the mouse or if theres ANY movement you see washed out colours/ something that looks like cell shaded? It's the best in words I can say but I have no idea whats going on with the screen. Is it my graphics card or the 4K itself?
Also on a note, While the 4K is plugged in it makes my 1080p screen look way off what it used too. More blurry? I guess Am starting to think it could be my GPU but hopefully someone can help me.
