Dell Inspiron 15 7559 4k Horizontal screen tearing
When I installed windows it automatically found a driver for both the nvidia 960m and intel hd 530. I went to nvidia site and installed the latest drivers even though they warned it may cause instability. When I realized things were going wrong with the screen tearing I immediately uninstalled and installed the correct video drivers from the website here. However I am still having problems with screen tearing horizontally across the whole screen at least with videos playing through steam. At the time of the screen tearing I did have my laptop connected to my 1080p tv via hdmi. Any ideas? Do I need to reinstall windows completely to get rid of the newest nvidia driver I installed?
