Laptop FPS player looking for monitor

Hello, Im currently using a laptop and I love playing fps games like cs2 and Valorant. I know a desktop PC would be better but right now its not an option for me because I move around a lot, so I need something portable.

Performance isnt an issue, but the small screen is. My eyesight is good, but im thinking about getting an external monitor for more comfort.

Can anyone recommend monitor in the 20-22” range thats lightweight, easy to carry, and doesnt take up too much space? Once my situation stabilizes i will probably switch to a desktop setup. Also if it matters, my laptop gets around 200 fps in these games, sometimes even more.
