UMax 18.5" FHD

Uperfect is fine. If its really is 125% srgb, that is more than enough to show you all the colours. 2000:1 contrast is also above average compared to the usual 1000:1 for screens that sized. It loses massively to any normal monitor its size, but is good for a portable one.

Running into a similar issue with Uperfect monitors that claim 120hz+ but can't run that stable. I have to downgrade to 60hz. Unfortunately, there aren't a lot of alternatives for something you can fit in a backpack. Curious to see responses.
