Packed Pixels

Its 2,048 x 1,536 resolution, packed into a 9.7-inch panel, might beat your own laptop. It hangs neatly in landscape or portrait mode, powers itself via USB, and plugs in via DisplayPort or – via an adapter – through a USB-C port. £149, packedpixels.com

Asus MB169C+

Asus’s 1,920 x 1,080, 15.6inch panel is a tremendous laptop add-on for one key reason: you can power it and send signal to it via a single USB-C connector. The case converts to a stand, too, for true portable convenience. £200, asus.com

AOC E1759FWU

This AOC is huge at 17 inches, cheap, and compatible with just about every laptop since it works fine with older USB connectors; but don’t expect stellar performance unless you’re on a modern machine. Driving its 1,600 x 900 res at USB 2.0 speeds causes some display lag. £132, aoc-europe.com
