LG Announces "Super UHD" TV Lineup (digitaltrends.com)

An anonymous reader writes: LG Electronics will be showing off a new line of 4K Ultra-HD television sets at CES this week and a 98-inch 8K Super UHD giant. Digital Trends reports: "The UH9500 (screen sizes 55-86 inches) UH8500 (screen sizes 55-75 inches) and UH7700 (screen sizes 49-65 inches) share several traits in common. All will offer what LG is calling HDR Plus, which means all of the sets in this series can process and display High Dynamic Range content from a variety of sources, include LG's Color Prime tech for enhanced color brightness. These sets will also apply processing that aims to improve non-HDR content for an HDR-like experience."

Selling spyware as a feature, the sales department should be congratulated. No, the whole industry.

And this is only about that particular company's products, other smart tvs from other companies spy as well.

Firewalls in home routers need to get better. My TV is only able to access YouTube and Netflix, and nothing else. Not even the ad severs for YouTube.

Consumers need this level of choice now.

Can't wait to see these in public

Comming to a waiting room near you, thete will be one of these 4k+ TVs on the wall, only they will be connected to a cable or even an OTA digital converter box either which is outputting letter boxed SD which somehow still manages to get cropped by the set, or better yet a 4:3 SD Apicture in Strech-O-Vision! Just like I see most HD sets in public spaces today

Fun fact -- OTA HDTV was for a long time one of the highest (technical) quality sources available. Fairly high-bit-rate MPEG2 can look VERY good, and generally doesn't suffer from the recompression artifacts of a cable or satellite provider working to maximize the number of channels rather than the quality of any particular channel. Yes, a good Blu-ray or stream can provide better quality now, but for a waiting-room situation, OTA HDTV is probably the best bet going.

Not that there will be anything to watch, but at least your daytime TV will only be crappy due to content.

The naming for this is getting a little ridiculous. HD I could understand. But then to go to ultra high definition seemed a little silly. Super ultra high definition is a whole lot of silly. I suppose they have to give it some sort of name as most TV's that are being sold as 4K truly aren't. I'm going to stick with my 1080p HD for now. At least until the Extra big ass double plus good venti glorious super ultra high definition televisions are released with 8 billion K resolution. At that point, I'll need to wear a pair of 16 inch telescopes with 750X magnification to truly appreciate the resolution while sitting 10 feet away from it on my couch. Except there won't be any content and everything will have to be unconverted from 1080p blurays that were remastered in 4K.

DPI is a meaningless measure without viewing distance. Since 20/20 vision means 1 arc minute or 1/60th degree resolution, the maximum field of vision (FOV) the screen should cover is easy to calculate.

For 20/20 vision ("normal" = does not need correction):
1920 pixels * 1/60th degree = 32 degrees
3840 pixels * 1/60th degree = 64 degrees
7680 pixels * 1/60th degree = 128 degrees

If you have 20/20 vision then FullHD at 55" / 7 feet = 31.9 degrees is all you can see. That's a fairly normal couch distance, but 28" / 3.4 feet is much further away from a desktop screen than is normal. A UHD monitor at 28" / 1.7 feet = 61.8 degrees is plenty though.

For 20/16 vision (normal in young and healthy):
1920 pixels * 1/60th degree * 16/20 = 25.6 degrees
3840 pixels * 1/60th degree * 16/20 = 51.2 degrees
7680 pixels * 1/60th degree * 16/20 = 102.4 degrees

If you have 20/16 vision as about 1/3rd of the population does, then UHD at 79" / 6 feet = 51.1 degrees is the limit of your vision. For a monitor 28" / 2.1 feet is slightly on the far side, maybe get a 5K monitor.

For 20/12 vision (the sharp-eyed):
1920 pixels * 1/60th degree * 8/20 = 19.2 degrees
3840 pixels * 1/60th degree * 8/20 = 38.4 degrees
7680 pixels * 1/60th degree * 8/20 = 76.8 degrees

Most people will won't ever see this good in their life ever, rare but also not truly exceptional. With UHD then 65" / 7 feet = 37.3 degrees is their limit, for a monitor 28" / 3 feet is clearly too long. An 8K monitor would actually be useful.

For 20/8 vision (the very, very few):
1920 pixels * 1/60th degree * 12/20 = 12.8 degrees
3840 pixels * 1/60th degree * 12/20 = 25.6 degrees
7680 pixels * 1/60th degree * 12/20 = 51.2 degrees

This is near the true limit of the human eye, there are a few elite baseball players like this. Since they have twice the vision of 20/16s, 8K at 79" / 6 feet = 51.1 degrees is the limit of their vision. For a monitor probably around 10K.

That became a much longer post than I expected...

11K.

I'm holding out for 11K.

... the first HD TV's came out in the late 90's...

I'm going to be nit-picky here and point you towards Wikipedia's article on HDTV.

In 1949, France started its transmissions with an 819 lines system (with 737 active lines). The system was monochrome only, and was used only on VHF for the first French TV channel. It was discontinued in 1983.

In 1958, the Soviet Union developed ransformator (Russian: , meaning Transformer), the first high-resolution (definition) television system capable of producing an image composed of 1,125 lines of resolution aimed at providing teleconferencing for military command. It was a research project and the system was never deployed by either the military or consumer broadcasting.

In 1979, the Japanese state broadcaster NHK first developed consumer high-definition television with a 5:3 display aspect ratio.[4] The system, known as Hi-Vision or MUSE after its Multiple sub-Nyquist sampling encoding for encoding the signal, required about twice the bandwidth of the existing NTSC system but provided about four times the resolution (1080i/1125 lines). Satellite test broadcasts started in 1989, with regular testing starting in 1991 and regular broadcasting of BS-9ch commencing on November 25, 1994, which featured commercial and NHK programming.

These are systems dating back to the start of the Korean War pretty much, and are "high definition" resolutions. Regardless of how popular they were (or were not) they existed, and therefore display devices capable of using them also existed. You can discount the first two if you want because they were military applications or false-starters, but the Japanese system was definitely in the consumer market.
