Samsung demos 82" quad-HD panel
Author: Gareth HalfacreePublished: 19th May 2008
The new Samsung LCD panel measures an impressive 82" and features LED backlighting and a 120Hz refresh rate.
According to the Korea Times the troubled company has presented its latest achievement at the Society for Information Display show in Los Angeles – and it's a monster.
Measuring a whopping 82” on the diagonal, the ultra-high definition LCD display can not only muster a 120Hz screen refresh rate – double that of most models, which run at 60Hz – but has a native resolution of 3840x2160, some four times as much as a traditional 1080p display. The display is rounded off with a LED backlight that increases the contrast ratio and improves the black level when compared with a fluorescent backlight.
Kim Sang Soo, executive vice president of the corporation's LCD Technology Centre, stated that he “personally [hopes] that the next-generation ultra-high definition level in the LCD panel market will open soon, with increasing consumer demand for clear viewing in households and public spaces.” It's clear that he believes this product has a market outside the business world, but the question is – what would you use to drive it?
Putting aside the possibility of using it as a large PC monitor for the particularly well-heeled gamer, can a display running at a resolution of 3840x2160 really offer an improvement over a 1920x1080 unit when fed with the most common HD sources – 1080p Blu-Ray discs and 720p/1080i HD broadcasts via satellite? I'm not entirely convinced – but that's not to say I would refuse one for the living room, if any Samsung reps are reading this.
Also demonstrating new products at the SID show was LG Electronics, who have perfected a roll-printing technology designed to replace the traditional photolithography process used in the production of LCD panels. The technology holds the promise of reducing the quantity of nasty chemicals required in the production of LCDs and also the possibility of flexible display screens at a sensible price.
The Society for Information Display 2008 International Symposium, Seminar and Exhibition will run until the 23rd May.
Anyone here fancy getting their hands on a quad-HD 82” screen, or are you still suitably impressed by standard 1080p panels? Share your thoughts over in the forums.

Aside from some pretty esoteric AV gear, nothing can output/scale to 2160p anyway.
I was under the impression that 2560x1600 was the max that dual-link can accomodate, let alone the fact that even tri/quad SLI would struggle with modern games at that obscene res

When you read the specs, you hope it has 10 hdmi ports, loads of scarts, a few optical in/out, dvi, display port etc, especially considering that's not a cheap piece of equipment, having said that, it's a Samsung, so it's already £1000 less than any Similar spec Sony/Panasonic.

if you can afford that screen im sure the 1000 pounds less wouldnt worry you at all
3840x2160 is 2160p so this is the same res as the Panasonic.
A "mere" 82" with 2160p res has about the same dot pitch as a 40/42" 1080p LCD. It annoys me when people say "you'll only see the benefit of 1080p on a TV of size x or larger" - a 40" TV from 4ft has exactly the same perceived size as a 20" from 2ft or a 60" from 6ft. That is, it fills the same portion of your vision and each pixel fills the same portion so appears the same size. So you'd have to sit closer to an 82" 2160p TV to see the benefits than you would to a 150", but sitting at that (closer) distance from a 150" would be as uncomfortable as using a 50" LCD as a normal desktop monitor 18" in front of your nose - not pleasant!
To see the full benefits of 2160p on an 82" you're going to have to sit pretty close.
The bigger the TV, the bigger the room its likely to sit in, the further away someone is going to be sitting.
For home use, I feel that 2160p is a little bit pointless in anything but a dedicated cinema, where you're likely to have a truly mahoosive screen (ie, the 150" Panny) and sit relatively close to it, as compared to a standard TV.
What I'm saying is, the distance one is likely to be sitting from an 82" TV is unlikely to show the benefits of 2160p (not that there's any content in this res to start with), whereas you're more likely to see it on the 150" Panny, simply due to the fact that a screen like that isn't going to live anywhere but its own dedicated room.
Sitting close to a 150" watching a film is also a lot different to sitting close to a 50" using it as a monitor. I've done both, the former is heavenly, the latter is simply uncomfortable.
Totally pointless if you ask me.
Not quite as interesting as the field emission displays I saw at the NAB show in Vegas recently, which offer all the advantages of both LCD and CRT with none of the disadvantages:
