Hello everyone who is seeing this article. I bought a new Msi Armor Rx480 OC 4gb to replace the old 270x.
Everything works just fine, from the installation of the card itself to installing the driver(16.11.4/ 16.9.2), then the problem appears.
After installing the driver, the monitor starts displaying 'purple-ish' lines which look like adding a blank line between every 'vertical pixel-line' and add a purple filter on it.
Then I turn off the GPU scaling in Radeon setting and everything looks fine until i playing games with full-screen mode except league of legend.
I am using and old Acer monitor-'p235H', HDMI 2.0 cable, RX480 with driver(16.11.4/ 16.9.2, same problem with both version)
PLZ~~~I need some help....
btw, if i change the resolution to 1776 x 1000 in full screen it looks perfectly within black border, all mess up in 1920 x 1080 fullscreen.
