So I got my GPU and tried several games and videos at 1440P and I love the clarity of the picture. I am using a Pixio PX329 monitor which I know is not top of the line but works fine. So for the most part I am really pleased, except when we play Minecraft on this PC.  The graphics seem...dirty. Flowers and mobs sometimes appear with a shimmer around them or a halo type thing. It happens mostly with bright colors like you can see in the picture.  The flowers should not look superimposed on the screen. Does anyone have any ideas of what settings to manipulate to clean the picture? Sorry had issues with the file upload
