In an OLED? They weren’t affordable 10 years ago.
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
I have never heard of an LCD making a high pitched noise like that, I think your monitor may be haunted
