4K VIdeo

"Roger M. Jenson" <r...@eyedigix.com>: Dec 17 11:20AM -0600 My journey to 4K video began with the purchase of a GoPro Hero 10 camera and editing drone video for a friend. My laptop computer had a 4K output so I went shopping for a 4K monitor. My laptop computer has Nvidia graphics for high resolution graphics so I looked for a monitor that supported G-sync. To avoid video issues I have always used AMD graphics cards in my desktop computer. After a bit of research I purchased a 27" LG Ultragear UHD Nano IPS monitor. This works great with both of my computers but the story does not end there. I have had intermittent video lockups while the audio keeps playing and the computer does not to keyboard or mouse input. Searching the logs I found GPU errors in syslog. Is this a hardware or software issue? Since it is easier to replace the hardware I took this opportunity to upgrade to a 4K AMD GPU. I purchased a XFX Radeon RX 580 GTS GPU, backed up my desktop computer, installed the GPU with only one issue. All the text was so small that it was hard to read. I am running Pop!_OS 22.04 LTS so I enabled Fractional Scaling and decided 150% worked the best for me. The Thunderbird email program did not follow the system font scaling so I changed the font size by doing to the menu bar > View > Font Size to adjust it.   I am on the second day without a video lock up so I may have solved my problem.   Having Fun, Roger M. Jenson
