I took and installed today Sapphire RX580 nitro + and immediately got a problem - the resolution of my monitor (LG 29UM59) 2560x1080 disappeared in the system. The maximum that is is 1920x1080, which is why the image looks stretched.
The monitor is connected with an HDMI cable (monitor side) - DVI-D (video card side).
I tried to install drivers versions 19.1.1 and 19.4.1 - to no avail. With the old GTX 660, a resolution of 2560x1080 is available even without installing drivers.
