15.6" 4K Portable Displays?

[H8rlequin]

This is probably a long shot, but has anyone ever dealt this lot? https://cforcedesign.com/products/cf015c-4k-ultra-slim-portable-display

I'm currently using a Dell 5290, 2-in-1 lappy, which I love very much, but it does not have a 4K display, which I don't love.
I didn't even know portable displays were a thing until I saw a special from Takealot a couple of days ago (1080P monitor only), so never thought it was an option, but since I've seen it I'm itching to get something.

Any thoughts on this? Positives and negatives on portable monitors?

Can't say much about portable monitors, but I have an HP EliteBook which has a 15.6" 4K display.

Honestly: it's not necessary at that physical size. 1920x1080 is fine. Using 4k either makes everything too small to see with human eyes, or you have to scale the resolution up and use four pixels instead of one... so you may as well just have gotten a 1080p display.

Just my 2c.
