Oddly enough a number of good Windows features showed up first in Vista. I think people just weren't ready for the barrage of security permission dialogs and having their printer drivers broken. ;-)

A lot of Vista's issues were driver quality-- Creative Labs and NVIDIA played chicken with Microsoft over the "no more kernel drivers" decision and it took a lot of time for the post-XP drivers to get even remotely good. Creative Labs never did get caught up-- they decided to just do the bare minimum necessary.

> …essentially the only 5K displays available are the LG one made in partnership with Apple, which is over a grand and has numerous quality issues… Are these documented anywhere? I have one (it's glorious) and I've not had a problem with it, but it'd be interesting to see the list.

I’ve seen lots of reports of interference with WiFi and/or Bluetooth on the older models (I believe since fixed). Recent models have lots of reports of bad backlight uniformity: https://forums.macrumors.com/threads/lg-5k-ultrafine-27md5kl...

Interesting, thank you!

I think I must be some weird outlier on HDR. I recently upgraded to a display that supports it, and when I turn it on, everything just looks darker to me. As though the brightness went to half at the same time that contrast was cranked up high. Playing with color and exposure and other settings just made things worse.

HDR needs a bunch of things to work correctly: 1) the software needs to render with the correct gamut profile (typically "P3.display") 2) the OS needs to have a reasonable color profile for the display that knows about the higher gamut 3) the display needs to be in the correct mode to interpret and render in the correct gamut. My LG HDR400 display only has 1 obvious setting for HDR as a "quick" setting, but it behave…

If I'm on a standard Win10 Pro box, any idea what I should look for? I'm running a amd vega 64.

It sounds like your display is not really HDR but is just advertised it. Monitors that are IPS (i.e. most monitors) with HDR are more mostly fake. If you want real HDR600, try the Samsung Odyssey G7; but even that does not have full-array local dimming (which you'd expect to spend $2k for).

It's not IPS: Asus gaming monitor with standard HDR10 support.

Having some similar issues. The thing is that the OSD controls are nice and bright- so the brightness is there, but all the actual video content seems mostly darker than the previous non HDR TV.

I actually just got an HDR tv too, in addition to the computer display... Luckily HDR wasn't a selling point for either decision. On the TV (samsung q70 qled) I just don't notice a difference on or off.

HDR10 isn’t really “HDR”. You want at least HDR600.

Anything else, in my opinion, is like selling LTE as “5Ge”.

I have one regret from this article, and that’s the explanation that sRGB hex color #ffffff (255, 255, 255) is being remapped. It’s not. The OS simply isn’t restricting the display pipeline to sRGB anymore, and that allows content which exceeds sRGB to do so. #ffffff is L=100%. What is L=800%? It exists in HDR content, and we can’t just make the web color #ffffff a dim gray to the eye. We must start thinking in terms…

I'm not sure why you would say it's not really HDR. It is. It's the base standard, the others use the same 10bit dynamic colors range. The 400/500/600 just refer to the maximum brightness of the display, something that may be a benefit but is not related to whether or not something is "true" HDR. HDR10 is true HDR. All HDR600 etc are also HDR10 with the added benefit of increased brightness.

Don't take it personal, it's just an objective view on things. I'm aware many people here have some emotional attachment to Apple products, but this doesn't warrant such a passive-aggressive response.

HDR600 etc are not just a maximum required brightness but also a minimum required black value. That gives you an actual dynamic range; 10bit is not a range, it's a resolution.
