Seems to be the way of it. When you start wanting things like 4k, good HDR, or (heavens forbid) low latency for games, the selections get a lot tighter.
Actually, my employer tried to get a Sceptre as a reasonable accommodation for someone with low vision (needed everything to be huge). That panel was so unusable not even the legally blind want to look at it.

Didn’t spent much time looking at Walmart however.
