Resolution loss problem in LG 29UM59-P

Discussion created by cis774 on Apr 25, 2020

I'm using the LG 29UM59-P.
Although I used it with the resolution 2560×1080 until the day before yesterday, resolution was suddenly dropped to 1920×1080 from yesterday, and it did not return.
When I removed the AMD Radeon Vega(TM) 11 graphics driver, reinstalled the monitor's driver and rebooted, the resolution returned to 2560×1080 for a moment, but again the AMD driver was automatically installed and the resolution was dropped.
Do you have any solutions?
