Just an FYI to anyone looking for a portable-ish second screen for their framework 16 or 13 (AMD), I Kickstarted this one on the assumption that it MIGHT work (but got nervous when some other folks on the forum reported difficulties with some other monitors).
Happy to report that this one (the 16" ‘pro’ version) works just fine with a single cable off the USB4 port on win11 on both my framework 13 (AMD mobo) and 16.
