They've gotten cheaper and then expensive again. In recent years you have niggers paying $500 at a minimum for some bogus features like VRR, HDR, VRR 2.0 with HDR, full array local dimming, wide gamut version 774317, a few extra Hz, ultrawide + fixes to make it work, some other shit features that we forgot existed 5 months after shilling ended, etc. Shit even the marketing campaign of renaming LCD screens to "LED monitors" had everyone trashing their current trash and buying a new trash with LED backlight instead of CCFL.
>Larger and cheaper
The standard has been ~24" for like 10 years now, with lots of people moving to 27" recently (in the 16:9 market). Not that any of that makes a huge difference. Pixel density only became a thing (outside the sane 0.1%ers) recently too.
And to top this all off, not only does each generation have 10x more bugs, but each improvement necessarily trades something off. Like going to 120Hz/144Hz resulted in tons of horse-shit response times.
