Is HDR a competitor to Dolby Vision? How about QLED (which I saw at Sams Club and liked)? Which do I need?
UHD = Ultra High Definition 3840 x 2160 resolution
Dolby Vision is a higher standard than HDR.
If you get Dolby Vision, you're going to get HDR.
QLED is a Samsung technology. It offers a purely wavelength frequency for the LED backlight. This is supposed to lead to purer/more accurate colors with less washout (better gamut reproduction). However most experts agree that is still inferior to OLED color gamut and contrast. There have been numerous scattered reports of expensive QLED Samsung sets failing after a year.
OLED is visually superior over LED (even FALD (Full array local dimming) backlight) in terms of contrast and color. But it isn't as bright. So HDR has less of an impact. But LG's OLEDs do reach HDR-10 levels. There is concern by some about what HDR does to the OLED lifetime as it's being over driven.
I take both issues with a grain of salt. One thing is for sure, if you buy a unit with HDR make sure the processor handles 18Gbps data rate with HDMI 2.0a at least.
Or like me, wait a few years for HDMI 2.1 and all the HDR rendering content issues are ironed out. Right now it's like the early days of DVD processors where there's a lot of variance source and of how one processor handles the data stream to another. Some might be strong in one area, and poor in another.
TCL units are a decent buy and they have built in Roku HDR support. (They are consistently highly rated as a best buy) But I'm not a fan of built in smart hardware as you never know what information they are skimming off you or when support will end.
