Samsung's 85-inch 8K TV will cost you $15,000 – CNET


Ready or not, the first 8K TV widely available is the US is now available to buy -- but it's going to cost you a pretty penny to be cutting-edge.

The Q900 sits atop Samsung's QLED TV line for 2018. It's not quite The Wall, but it's still huge in every way. The Q900's 85-inch screen is packed with more than 33 million pixels, four times the resolution of conventional 4K TVs. And its price tag is mammoth, too: $14,999. It's available to buy now. (Brits can preorder the UK version here for £6,999. It's not yet available in Australia.)

The appeal of 8K, according to Samsung, is that with ever-larger screen sizes you'll need higher resolutions to appreciate them. And other companies are on-board too. The Q900 is the first 8K TV you can buy in the US, but Sharp's 70-inch LV-70X500E 8K monitor started shipping earlier this year to Europe (for 11,000 euros) after going on sale in late 2017 in China, Japan and Taiwan. Whether 8K TVs actually look any sharper than 4K TVs, however, remains to be seen. Even at screen sizes this vast, all those pixels might be so much overkill. 

As we've explained many times with 4K TVs, there's a point of diminishing returns when it comes to resolution. The human eye can only see so much detail, and extra pixels beyond what you can discern are basically wasted. To get anything out of higher resolutions and their proportionally tinier pixels, you need to sit closer, get a bigger TV, or both.

Plenty of sources exist in 4K resolution today, including Netflix, Amazon, YouTube, Vudu and 4K Blu-ray discs, but there are basically no 8K movies or TV shows available right now. The exception is a few YouTube videos, but Samsung's rep says that the Q900 will not be able to play them in 8K yet (that may change in the future, says the rep, once the compression technology is ready). The Q900 has an HEVC decoder that can handle 8K streaming up to 60 frames per second, once the services deliver it. The TV's USB port can also handle 8K/60.

For now with the vast majority of stuff you'll watch, the Q900 has to rely on upscaling standard HD and 4K content to fill its higher pixel count.

Expanding upon the Q9S it showed at CES, Samsung says it has completely redesigned the scaling on the Q900 for 8K. It uses a new 8K Quantum processor and artificial intelligence to improve texture, smooth jagged edges and reduce noise and blurring. "A database analyses millions of sets of low and high resolution content and uses machine learning to develop algorithms" used for upscaling, Samsung says, and it can update the TV over time with improved formulas.

That sounds pretty cool, but if the past is any indication, upscaled 4K or 1080p will still look worse than native 8K content. Assuming you can tell the difference.

Based on the math of human visual acuity, you'll need to sit really close to an 85-inch 8K screen to get any benefit of the extra resolution. Carlton Bale's superb home theater calculator, for example, says you'll need to sit 3 feet or closer (to a screen that's more than 7 feet diagonal) to see all the detail of 8K, and 5 feet or closer to see the full benefit of 4K. In other words, from further than 5 feet away you won't be able to see any benefit of an 8K TV compared to a 4K TV.

Having not tested Samsung's 85-inch 8K TV next to one with 4K resolution, I can't say for sure whether that's true. But based on past comparisons of lower resolution 1080p versus 4K TVs, I expect any increase in sharpness to be minor at best.

Beyond upscaling and resolution, the Q900 will be Samsung's brightest TV. It can belt out 4000 nits in HDR highlights, which almost doubles that of the current Q9, and should lead to punchy HDR, especially in combination with the Q900's full array local dimming. Its number of dimming zones is "slightly" higher than the Q9, but as usual Samsung didn't specify a number. 

The Q900 has all the other extras of the Q9, including ambient mode, the external OneConnect input box with an "invisible" connection, HDR10+ compatibility and all the smart TV fixins.

On the other hand, Samsung can't confirm that the Q900 has HDMI 2.1-capable inputs, something I expected to see on the first 8K TVs because it delivers higher bandwidth than HDMI 2.0. Samsung's rep said the issue was that the HDMI test specification wasn't ready yet, so he couldn't comment on whether the TV would be HDMI 2.1-certified in the future. 

The rep did specify that (like other Samsung sets) the Q900 supports some aspects of HDMI 2.1, specifically Variable Refresh Rate (VRR), High Frame Rate (HFR) and Dynamic HDR. The TV's HDMI inputs will not handle 8K resolutions at 60 frames per second, however, maxing out at 8K/30. It will handle 4K/60, and may handle 4K/120 with a forthcoming firmware update.

The only 8K TV Samsung announced for the US is the 85-inch Q900, but it did say other global markets would get smaller 8K QLED TVs, namely 65, 75, 82 and 85-inches. Further details weren't immediately available.

Since it's so large, the 85-inch Q900 doesn't face much direct competition at the high end of the TV market. The flagship TVs of competitors, namely the Sony Z9F and the LG C8 OLED TV, max out at 75 and 77 inches respectively. For that reason it will probably be the best TV available at its size, regardless of whether 8K makes a visible difference. At least until LG's 88-inch 8K OLED comes out.
