Meanwhile, for the average Joe computer user (like me) who just wants a decent productivity-but-also-sometimes-gaming monitor with half-decent colour and a good refresh rate, Dell upgraded their
UltraSharp TB 4K monitors a few weeks ago.
$700 gets you a really decent 4k 120Hz monitor with very good picture and colour accuracy, a plethora of connectivity options (including TB4 upstream and downstream with 140W power delivery for budget-conscious Mac users who might want two good monitors but not spend a small fortune on them), and some other kind of neat options like 2.5G Ethernet and a bunch of downstream USB-C and USB-A ports (including 2 C's and 1 A in a front-facing pop-down hub).
EDIT: I forgot two of the coolest features: It actually includes
both the HAS and VESA mount hardware in the box,
and it has a removable power cable!
