Every review here is a display you carry with a laptop: single USB-C or HDMI portable screens and clip-on triple-screen extenders. We compare what each listing states about ports, refresh rate and power, and say where it is silent.
One USB-C cable carries picture and power only if the port supports DisplayPort Alt Mode or Thunderbolt. Otherwise you need the monitor's HDMI input plus a separate power cable.
Check your laptop →A triple-screen extender takes one connection per panel. Base M1, M2 and M3 MacBooks drive one external display with the lid open; DisplayLink models are the workaround.
The laptop port, the cable and the monitor input all have to support it, and the operating system has to be set to it. Any one of them caps you at 60Hz.
Why it stays at 60Hz →Many laptops cannot power a bright portable screen on battery. A second USB-C port on the monitor lets a charger feed it directly.

They work over one USB-C cable only when the laptop's USB-C port carries video (DisplayPort Alt Mode or Thunderbolt). Laptops without that can use the monitor's HDMI input with a separate power cable, or a DisplayLink model that runs over ordinary USB with a driver.
Not natively on base M1, M2 or M3 models, which drive one external display with the lid open. The second panel needs DisplayLink software, or it mirrors the first. M4 and Pro/Max chips drive two.
The port, the cable and the monitor input must all support 144Hz, and the refresh rate must be selected in the display settings. A USB-C port that only does DisplayPort 1.2 over two lanes, or an HDMI 1.4 port, can hold it at 60Hz.
