I use an AMD RX580 with 2 Displays: 1 LG ultrawide with only HDMI input, native resolution 2560x1440 on the DisplayPort and 1 LG 4K TV on the HDMI port.
It had installed version 18.3.4 of Radeon Software Adrenalin and worked well on both displays with 2560x1440.
When I updated to version 21.2.3, DisplayPort is diseable the 2560x1440 resolution. The maximum resolution is now 1920x1080.
What can I do to have the resolutions of 2560x1440 on both displays again?
