4k resolution coming

Westinghouse shows off 4K TV
While the 4K format has yet to make an impact on the consumer market, budget brand Westinghouse is preparing its D55QX14K TV for release in 2013.

That TV is not techically a 4k TV, the term 4k is derived from the 4096 resolution.

That TV is 3840 so it's not 4k

It's close enough and it's in 16:9 format. Consumer products will use that resolution and it actually is classified as 4K also.

The HDMI 1.4 specification adds support for extremely high video resolutions that go far beyond today’s 1080p systems. 4K is shorthand for 4,000 lines wide by 2,000 lines high, or roughly four times the resolution of a 1080p display. The term actually covers two formats, both supported in the HDMI 1.4 specification:

3840 pixels wide by 2160 pixels high
4096 pixels wide by 2160 pixels high

That's like saying 1680x1050 is Full HD....

Umm.. No it's not. Those two resolutions in the spec have the same vertical resolution and PPI, but the 4096*2160 just has a wider than 16:9 cinema aspect ratio.

Because the tubes were massive and expensive.

FYI, my old 32" flat-screen CRT television has 60+kg of glass in the tube!

Most 4k sets have less than 4000 columns. 3840 x 2160 is a close resolution at a simple doubling of each dimension of 1080p, which is good for upscaling and I guess good for manufacture. The official standard UHD is this 3840x2160. 4k column displays/projectors aren't 16:9 either. Thus 4k has been adopted as the simple term for describing the increased res, instead of QTHD (quad-true HD) or 3.8k. It's not really different to CRTs having less visible screen than the given diagonal dimension, or car manufacturers rounding their engine capacity (rather optimistically). Of course, if they'd stuck with 2160p we could be exact and consistent.

Some of the first HDTVs were sub 720. Especially the CRTs and the early plasmas.

Took a couple of years before they hit actual 720p, 1080i and then eventually 1080p.

Doesn't pay to be an early-adopter to new formats and will probably be the case with 4K TVs.

 

[Shifty Geezer]

4k sets have a standard similar to the EU's HD Ready standard. And given stats are available, I don't think being an early adopter is a major risk. You won't be buying a 4k set today only for next-year's model to have a higher resolution. The only risk I see is the connection. If HDMI is replaced prior to mainstream adoption...it's still immaterial. If you're shelling out thousands of bucks on a 4k TV, you must be ready and able to replace it if a new tech comes out. Otherwise you shouldn't be spending that much on a TV!

They re-branded 4K to UHDTV / Ultra High-Definition Television last week.

There you go, then. A marketing term has been coined. 4k remains a casual reference though, and will remain in technical conversation, I'm sure, as it's used in cinema

 

[Davros]

This should really be in the pc section as that is the natural home seeing as pc's already support this resolution and a few people are playing at higher than 3840x2160 (although at a lesser ppi)

 

[I.S.T.]

Not really, given it's about TVs mostly.

I wouldn't be surprised if 4k remains in marketing. Just like HD and FullHD never fully replaced 720p and 1080p in marketing.

Especially when 4k looks so much larger than 1080.

The LG 84" 4k TV has just or is just hitting the market. I noticed that a store in Finland is selling it for 12k€ . Cheaper than what I expected at this point and I'm guessing in 2-3 years something like a 65"-70" could be quite a bit cheaper. I would love to see that LG in action.

I just got a 60" Sharp for myself, but hey maybe my next TV will be something like that

It has no bearing on (console) gaming, so no, we're not overly interested.

Have moved it to 3D Hardware, Software & Output Devices. Is that better?

Yup, definitely it looks cool now Thanks

The difference in image quality between SD and HD even on a HD Ready 32 inch LED TV is staggering. I can imagine that the difference in details, sharpness and crispness between HD and 4K would be even more pronounced.

Let's hope they will push it and soon we will enjoy more beauties
