Issue:
Want to add a new resolution (2560X1440) to the external monitor (Lenovo ThinkVision E27q-20 27). The highest resolution available is 1920X1080. Getting an error when trying to output new mode that was added.
Steps taken:
Verified that the desired resolution is supported using the following command:
cvt 2560 1440
2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync
Added a new mode using the xrandr command and it is reflected in the xrandr list.
