Well... I didn't say "affordable." I spent as much on this monitor as I spent on a laptop in grad school ($700ish). Three factors for me here: I transitioned to working from home and the expense was tax-deductable; I'm not in grad school anymore; I'm very frugal, so when do make a rare purchase, I go for quality.
This is not an endorsement. I've got some issues with the monitor -- it does something weird displaying certain patterns, which comes up for me occasionally. Also, sometimes, the curved screen bugs me, because straight lines aren't straight. YMMV
It's quite decent, I use that when I work at the office, it can be bought for 550$cad if you wait for a sales.
When I work from home I use a Samsung 49" ultrawide (5120x1440p@120Hz). Moving the taskbar vertically on the left and using Windows FancyZone make that a wonderful and productive experience. My wife says that I appear to work for mission control at NASA with that setup; this make my inner nerd happy!
I got a decently inexpensive 2k curved Phillips monitor at the beginning of the pandemic. Pretty happy with it (lucky buy, given that I didn't know it would be my window to the world for a couple years). At the time at least, 4k was still quite expensive. I don't know how much benefit 4k provides at typical desktop usage distances.
(328E9FJAB but I suspect you can find plenty that are just as good in the 2k range).
What model do you use?
