There does not seem to be a limit on how dark or bright a display can be when presenting SDR content considering some displays providing SDR can get brighter than an OLED providing HDR, and an OLED providing SDR can get darker than some displays that are providing HDR. So is it safe to say there is still not a perfect SDR display available on the market, probably until a display technology such as microLED matures? Does anyone know if there is a maximum limit for the color gamut of an SDR display, such as DCI P3 or Rec 2020? post edited by boylerya - Thursday, November 29, 2018 4:31 AM United We Stand...Six Feet Apart.

Thursday, November 29, 2018 8:34 PM (permalink) IMHO HDR is just a nice sounding buzzword for a bunch of newer protocols, and is not really applicable directly to the PC space. SDR/HDR are just the signalling standards, and yes HDR does have more color space and luminance information, but it's mostly just extensions/upgrades of the protocols used for SDR. HDR could well be called SDR 2.0, it's more that we finally started making consumer displays that have good enough color reproduction to need a better standard. PCs have been capable of higher color space for a long time before HDR came around (how do you think they master the HDR content in the first place). #2
