“Portable monitor” on Amazon turns up some choices, from monitors that stand alone to ones that clip onto your laptop and fold out. Here is a 4K choice: https://www.amazon.com/Corkea-3840×2160-Resolution-Touchscreen-Cellphone/dp/B08131MVGT/ref=mp_s_a_1_9?dchild=1&keywords=17+inch+portable+monitor+4k&pd_rd_r=fb7b1849-566f-4333-a447-e213605dffea&pd_rd_w=VbmJT&pd_rd_wg=wltNS&pf_rd_p=9ab5c07f-ecbc-469e-955f-4dd6d65646b8&pf_rd_r=6S53EDQNGKNXR3X1X5A8&qid=1601979925&sr=8-9

The iPad + Sidecar idea is interesting too.

I, too, have a hard time working with just one screen. I think it would be interesting to take two or three portable monitors, come up with a collapsing and slim stand, and have a multi monitor rig that could be quickly unfolded and set up in a hotel room etc.
