I've recently been in the market for a high quality display and I've found nothing that comes even close to my 15 year old NEC MultiSync LCD2490WUXi in terms of black quality. That monitor has the "A-TW" or "Advanced True Wide" (or is it "Advanced True White"? No one knows for sure...) polarizer which eliminates IPS glow in exchange for color shifting when viewed off axis -- see the album for a demonstration, and remember that cameras greatly exaggerate the color shift caused by the polarizer similar to how they exaggerate the effects of IPS glow and backlight bleed.
Why was this polarizer technology abandoned? In the last few weeks I've bought and returned an Asus PG279QZ (twice), Acer XB271HU, Acer XB271HK, and a Nixeus NX-EDG27s v2 because they all look terrible compared to my ancient NEC. On these modern monitors I can see glow in the corners during normal usage (movies and games), and some (Asus) had such bad backlight bleed that it was visible in the daytime with the sun shining directly on the panel.
It's insane to me that we've been stuck with the same trash-tier AUO IPS panel for the last 5 years with zero improvement (in fact, a regression) in image quality over its decade-old predecessors. I remember when the Asus PG279Q first came out it seemed like the perfect monitor until the bleed, glow, and QC issues came up; the "revised" PG279QZ is a worse monitor in all respects, having lower brightness and thicker bezels without any accompanying improvements. Innolux's IPS panel and other VA panels are all cursed with stupidly slow response times and ghosting issues.
I will give these newer monitors credit where it is due, though - variable refresh rate technology is amazing, input lag is essentially a non-issue now (my NEC has >100ms input lag), and modern IPS panels can have response times which once were thought to be exclusively achievable by TN panels.
But why did we give up improving on black quality? The common refrain nowadays is "wait for OLED" or "wait for microLED", but why should that stop us from improving what we already have? Emissive displays aren't going to be economical for some time yet, and the other paths forward that are being explored are misguided (FALD) or similarly uneconomical (stacked LCD; Eizo sells this, but for $30,000).
