after installing graphics driver screen is weird

I just did a fresh install of windows 10 on my pc and this time when I started windows update it went all weird

I have a rx480 desktop drivers hdmi on a tv I have an i5-6500

and a 800 watt power supply and 8gb of ram



this is what my screen looks like I don't know what to make of it really

you cant see the bottom of the screen and when I move the mouse it makes a trail so does everything elseIMG_0077.JPG
