#Linux mint change resolution and display stopped working 1080p
However, it only lets me do 1080p max in my display settings. Just got a new display (Samsung LC27JG50QQU, 1440p, 144hz) which is plugged into my AMD Radeon HD 6950 (DVI-D, DVI-I, HDMI 1.4, 2x Mini DisplayPort) graphics card using HDMI.
