Hell, modern displays are just now starting to catch up to CRTs in the input lag and motion blur department.
It was brutal putting up with these shitty LCDs for two whole decades, especially the fact that we had to put up with 60Hz and sub-1080p resolutions, when my CRT was displaying a 1600x1200 picture at 85Hz in the 90s! It wasn't until I got a 4K 120Hz OLED with VRR and HDR couple years ago that I finally stopped missing CRTs, cause I finally felt like I had something superior.
Twenty fucking years of waiting for something to surpass the good old CRT. Unbelievable.
LCDs came in just in time for me to be attending LAN parties in uni. Got sick of lugging my CRT up the stairs once a week pretty quickly and was glad when I managed to get my hands on an LCD. I can't even remember if I noticed the downgrade, I was so thrilled with the portability.
Not just input lag (I mean I literally mentioned other things too but you obviously didn't read my entire comment) but also contrast ratio, brightness in LUX, color volume and accuracy, response time, viewing angle, displaying non-native resolutions clearly, flicker, stutter... Should I go on?
All things that LCDs struggled on and still struggle on. OLED fixes most of these issues, and is the only display tech that I'd consider superior to a CRT.
Most people didn't own a CRT capable of 1600x1200@85Hz, most were barely if any better in resolution department than your average "cube" LCDs (one which I'm currently using besides my main 32" QHD display). I have owned a gargantuan beast like that with a Trinitron tube, I could run it at 120Hz at 1024x768 and at higher resolutions without much flicker, but it had issues with the PCBs cracking, so it was replaced to a much more mediocre and smaller CRT with much lower refresh rates.
A 10 year old LCD is not good. The resolution and refresh rate is irrelevant if it's not an OLED, which as I said, is the only display tech good enough to replace a CRT.
Not an OLED, in an IPS LCD. You're asserting that OLED is the only tech good enough (which is not true, QLED displays are also starting to get good enough to surpass OLED, they're just more expensive), but the response time of IPS displays frequently got under 10ms as long ago as 2014, and that's fast enough to be imperceptible by humans. Any other drawbacks of IPS compared to OLED were far worse with CRTs.
And they don't make that annoying high-pitched shriek.
I have an Asus proart 23" from twelve years ago that's great in terms of color (contrast and response time, not so much) but it produces a high pitched sound when at full brightness. I wondered if that was due to the panel tech itself
