Brightness Wars.... Over before the fight even started?

There have been two major things to happen over the last few years (since 2015) which have had the biggest impact on TV picture quality. Those two things are HDR and high brightness. I did not mention 4K (or 8K) as those are pretty much non-factors for most everything but viewing pictures up close on a large screen.

HDR wise, things have been a bit dissapointing, with the Vizio PXQ having the highest rec. 2020 % of every modern TV to date, while the OLED score quite a bit lower. Thing seemed to slow down on meeting 100% and no one is really pushing or even advertising rec 2020.

Even more disappointing is we are no where near 5000 nits with any TV with, again, the Vizio PXQ at the top of this category (pretty good for a 75" that can be found well under $2K). There was a time when brightness was heavily touted and Dolby was giving regular demos showing how more realistic a 5,000 nit picture can look, it is not about hurting your eyes, but adds realism to viewing.

It seems that now that Samsung and Sony are going OLED at the high end and some of the new tech TCL is using with dual panels makes achieving at very high nit count impossible. Therefore, they are pushing better blacks but not pushing brightness or more color gamut covered.

I have a dark room but I refuse to go OLED, not only due to pricing, but also burn in concerns and lack of brightness. I have watched some quality content on the Vizio PX and absolutely love it for it's picture quality. If it had better apps, a better CPU and a 85" size, this will be my choice and luckily, it will be a cheaper option for 2020.

Are you an alien who lives on the sun if that's the case then I get it but if not then something must be seriously wrong with you when a lg oled with a peak brightness of 800 nits is not bright enough for your dark room. Its sad when people who are clueless think that if the picture is very bright then it must be beautiful, they have no understanding of contrast, black levels and how blooming detracts from the picture.

I watch my 82" Q70R in a dark room (on SDR) with the backlight set to about half. I'm guessing that's around 300-400 nits. Its on the edge of being too bright. 5000 nits? Do you plan on watching with welding goggles?

Maybe you should know what you are talking about before opening your mouth? I have actually viewed demos at 4000 nits or close to it, in a darkened display area, and no, you are not blinded, the picture looks more realistic with quality content.

Although some experts have warned against going too far with peak luminance in next-generation televisions designs, Tyler Pruitt, technical evangelist with display calibration specialist Portrait Displays/SpectraCal and a SMPTE member, said existing standards aren’t nearly high enough.

Speaking at the Insight Media/Samsung-sponsored QLED and other Advanced Display Technology Summit in Los Angeles last month, Pruitt said that many have balked at Dolby’s 4,000 nit aspirational brightness levels for displays, warning that specular highlights would be blinding to audiences watching in dark rooms. But Sony demonstrated at CES 2018 that 10,000 nits “might not be high enough,” at least not for professional cinemas.

“Sony had a demo at CES that pretty much put to bed the notion that 10,000 nits was going to require sunglasses,” Pruitt told the gathering of content grading and production professionals. “They played pretty much the same image on their 2,000-nit Z9D and an 85-inch 8K prototype display and it made the Z9D picture look like SDR. It was in a dark room. It didn’t make your eyes hurt, and it made images look like they were right in front of you.”

Well at least it's not all about peak brightness. The single most important factor in picture quality, is contrast. And OLED right now, is the only one doing it perfectly. That's why it has the best picture despite a lower peak brightness.


People are finding that OLED strikes the perfect balance of brightness and contrast. and I'm sure the tech will continue to evolve to push out more nits but for now 800 nits is plenty with perfect contrast.

The point you are missing is brightness by itself cannot make a great picture you also need deep blacks, contrast and no blooming. I have the z9d which is twice the brightness of oled but yet HDR movies looks better on my oled tv in the home theater, which proves the importance of black levels and contrast. Oled will continue to provide the best picture quality until Microled becomes available to the consumer.
