UBegin J1

I have one for traveling, 2.5k 16 inch ips with a hole in left bottom corner. Works very well for 2 years already, probably was on for 24/7 in 6 month totally. Sound is crap (expected), max brightness could be better but is ok, powered via same type-c that connects it to computer (but also has another one for additional power if need). Actually I am surprised it working so good for that price, so could recommend. edit: I have UPerfect one

I don't have a PS5, but I use a 16" 1600p portable as one of my secondary displays. Something to keep in mind with the portable monitors is they're almost universally B-tier laptop panels shipped at max brightness settings with only volatile memory. They set them to run at max brightness by default and every time they're powered down they reset to default settings. I didn't realize that with my first one and burned it in within six months, this time I've got it set to stay powered and at half brightness. As long as you're mindful of the burn in risks it's not bad at all though, I bought the same exact uperfect display this time because despite the failure I genuinely like the panel, it has great pixel density and looks great.

I use UPerfect 16 inches, 2.5K almost two years as the secondary one for my MacBook 14 in. Still love it, even as it has a some glow zones on the top of the screen, not visible at all, especially with the light theme.

Flipgo from Jsaux. I have two of the 16in version and a 16in laptop and a Ugreen 16in portable monitor, 6 screens altogether, all fit in a small backpack. For small stays I just take the Ugreen with me. Every screen is 1600p vertically, I could never use only one screen of 1080p like the one in the glasses some people suggest, not that I did not try it. Flipgo exists also in 14inch Edit: sorry Uperfect not Ugreen is the brand of my single portable monitor

I know a lot of people just say to get 1080p monitors, but I recommend a 2560x1600 or 2560x1440 monitor so you can just run games at the Deck's 1280x800 or 1280x720 resolutions and have it scale nicely. For brands, Azorpa and Uperfect seem to get recommended a bit if you're looking on Amazon. I have a 16" Uperfect 2560x1600 and it works great for me. I don't know exactly what you mean by small-ish.

I bought a bunch of “ used “ portable monitors from this company on eBay . I paid $30 ish for about this spec and it’s brand new as far as I can tell. Think it’s called upperfect
