Why 8K TVs Matter

An in-depth look - complete with actual science and stuff - at how 8K takes the AV experience to a new Despite what its detractors might say.

Why 8K TVs Matter

Curated via Twitter from Forbes Tech’s twitter account….

Although this is not something Lee mentions in his research, it’s worth noting that HDR also introduces the potential for images to contain small, intense light peaks that you don’t get in SDR, and here again, provided a screen’s light management is good enough, the extra fineness in an 8K image has the potential to render these highlights – and the tiniest differences in them – more effectively than lower resolution screens.

The thinking is that the way your brain interprets the raw data being fed to it by your eyes amplifies the “stepping effect” angled lines exhibit when they appear on pixel-based screens, since it always tries to compile the information from your eyes into the sort of analogue, non-pixel based viewing experience we all see as we look at the real world.

A good way to start thinking about this is to recall that a lot of 4K high dynamic range content these days is mastered on the Sony BVM-X300: An OLED mastering monitor that crams its 4K resolution into a mere 30-inch screen.

Dr Lee’s findings that higher resolution displays increase a picture’s dynamic signal to noise ratio (reducing the amount of work your brain has to do and thereby making the viewing experience feel more immediate and immersive) opens a discussion about the need for high frame rates to really maximize 8K’s potential.

So that approach has been supplanted by a much superior AI “machine learning” system, where comparative analysis of different resolutions of the same content has been used to build huge databases of different picture sources and picture types. 8K TVs can call on these (regularly updated) databases in real time when figuring out how best to deal with sub-8K content.

Even with heavily compressed standard definition broadcasts or web streams, though, while you don’t tend to still get a sense of much extra resolution, both Samsung and Sony’s 8K sets do a strikingly good job of at least suppressing MPEG and other noise in such low-grade sources.

This explains why many viewers feel that higher resolution images look more three-dimensional – and it’s another resolution-related picture benefit that you can appreciate even from perfectly typical viewing distances.

The bottom line, though, is that even the first generations of 8K upscaling processing are good enough to give sub-8K sources at least some of the big-screen benefits of 8K described in ‘The Science Bit’ of this article without generating nearly as many unwanted problems as you might expect.

It tries to ‘upscale’ the pixel-based images the screen is showing to the essentially infinitely high resolution imagery it’s used to dealing with in the real world.

What’s more, because the way your brain interprets what your eyes feed to it so strongly amplifies even quite tiny ‘stepping’ issues, this sense of extra realness will still be visible from a substantially greater viewing distance than you’d be talking about if you were making calculations  based on just the Snellen visual acuity approach.

And so the less resolution your brain has to go on from a TV image, the harder its upscaling processor will have to work – and the less satisfying and real the final results will feel.

Samsung video expert Seungho Park suggested at the recent 8K Summit that research is also being done into a Deep Learning approach to upscaling, since the complexity this provides has the potential to deliver another sea-change in upscaling performance.

At the recent 8K Summit, Samsung America Marketing Director Sonia Chen presented data from research group IHS showing that by 2021 it’s estimated that 42% of North American households will have moved to TVs with screens of 65 inches or more.

Sharp has also launched a range of 8K monitors that have been available for a few months to consumers who don’t need built-in tuners (though they’re aimed more at the commercial display market), and LG is going to launch the first 8K OLED TV this year in the shape of the OLED88Z9PUA.

Also fascinating from the perspective of an 8K future for home video is the fact that already some studios have started making 8K rather than 4K digital remasters of movies originally shot on film, as they’re finding that you need a huge number of pixels to fully capture digitally every nuance of an analogue format like film.

Partly because he’s found that 8K is “a whole new ball game when it comes to revealing the subtle textures and colors found with nature and wildlife”, but also because in the work he does with the fashion industry, he’s been able to lift still frames from 8K video that retain enough resolution to appear in print magazines.

Remarkably, though, the 8K upscaling systems I’ve seen so far on the first 8K TVs from Samsung and Sony have been remarkably effective.
