Very few "HDR" TVs on the market today can pass DisplayHDR testing.
Every single TV with Ultra HD Premium certification - which is the only HDR TV's you should buy - will get VESA's DisplayHDR 1000. Compare the requirements and you'll see.
"Ultra HD Premium" is about peaknits, black level, resolution, 10 bit color depth, color space etc. No TV that can't fulfil those minimum requirements won't get the certification and this certification is like a DisplayHDR 1000 stamp. It was made because there were tons of TV claiming HDR, even tho they were using 8 bit panels and/or didn't have the nits to show HDR properly. PC needed DisplayHDR because HDR was (
and still is) a mess on PC monitors.
Ultra HD Premium has nothing to do with HDR standards like HDR10, HDR10+ or Dolby Vision. It's all about panel and hardware.
It is supposed to create clarity for customers, just like DisplayHDR. TV market does not need a guideline like DisplayHDR, because it's already present and have been for a long time now. If it has the logo, HDR experience will be good. DisplayHDR 400 is practially useless, 600 is "bad HDR", 1000 is needed for a decent HDR experience.
That OLED you linked will easily deliver better HDR than any DisplayHDR 1000 monitor - Because it's OLED. Nits requirement is for LCD tech. Please don't compare LCD with OLED. OLED has crazy blacks and contrast, they don't need those peaknits. Because of self emitting pixels.
Ultra HD Premium nits requirement is only 540 nits on OLED. Because black levels are simply night and day difference compared to backlit LCD (also much better than FALD LCD).
VESA's DisplayHDR is for PC ONLY and LCD TECH ONLY.
From their own homepage:
"Creating a specification for the PC industry that will be shared publicly and transparently"
VESA simply took Ultra HD Premium requirements for LCD and called it DisplayHDR 1000, then created 400 and 600 for a crappy HDR experience. Probably because monitor manufacturers could call their monitors "HDR". Take a look at member participants on DisplayHDR.org. Hardware and PC monitor manufaturers.
Also 75hz is far better than 60Hz.
Not really... Basicly both are bad. Needs at least 100+ Hz to be much better than 60. I prefer 120 Hz minimum tho.
60 Hz does not give you headache, it was probably the monitor itself; Not flicker free. This can give some people headache.
