Sony Corp. has announced that it will begin the phased launch of its latest Bravia LCD television in all global regions from the end of the year. The new Bravia boasts a 84" LCD panel with 4K (3840*2160) resolution. The TV incorporates Sony's “4K X-Reality Pro” super-resolution high picture quality engine. Sony follows LG Electronics with its 4K ultra high-definition TV-set (UHDTV) and both are driving the new level of visual perfection to the masses.

The new 84” Bravia 4K LCD TV comes equipped with a panel comprising approximately 8.29 megapixels (52 ppi), which is 4 times the resolution of Full HD standard, and incorporates special 4K X-Reality Pro video processor optimized for 4K TV. This engine is capable of upconverting a variety of content (including that in stereo-3D) with different resolutions, such as HD digital broadcasts or Blu-ray discs content, into crisp, high-quality images with 4K resolution. The UDHTV also comes with "10 unit live speaker" 50W side speaker system, with Sony's own signal-processing technology to provide accurate three-dimensional sound.

I might like one of these ....after they come down in price....

Would make a heck of a monitor....browsing from 10 feet away.

I love my 37” Visio HD. We sit close enough to where it fits our vision nicely. And it fits perfectly in our entertainment center. There’s only one problem; nothing worth watching.

An 84” TV? We’d have to rearrange a lot of deck chairs to get that to fit in.

How do you back pedal Pythagorus to get an idea what an 84 inch might be in the real world ?

I'm at 32" so I am dreaming big.....

My daughter has a Sony 55" hanging on a wall....I think an 84" would cove a better chunk of it.

TYPO correction:

would cover a better --

[ContraryMary]

I have a 55”. I can’t imagine an 84”; it would be too large for my living room.

84" 4K LCD TV
Will FLY out of the stores just like the 3D models. Oh wait ...

I’ve had a 54 incher for 2 years now and I can’t imagine ever going with anything smaller. I’ve got it in a small room too. I just measured it and the screen is exactly 5’ from the front edge of my couch. I would not have a problem upgrading to an 84 incher in that same space.

[bcsco]

We live in a bungalow. We’d have to eliminate the entertainment center. Even then, the wall space is limited.

No insurmountable issue except, the top of the entertainment center is where the Christmas village goes during the Christmas season. We have no other viable place to put it. And we like it there. One answer would be a lower, credenza style unit below the TV. But that’s throwing extra money into simply upgrading your TV. Maybe even close to what the TV would cost. I think I’ll wait...

I say you put this on your dock.

According to my TV screen comparison spreadsheet an 84 inch 16:9 TV would have a screen about 73 inches wide, 42 in height. If viewing a program in the old 4:3 ratio it would be the equivalent of a ~ 68 inch TV.

52 dots per inch?

No, thanks, I'll keep my 32" 1080P.

I bet the lag between audio and visual on these beasts in UHDTV mode across satellite will be untenable. I know when I first got my HDTV, there was a 3 second delay between audio and visual and it made watching TV painful. They finally had to implement buffering to fix the problem. This is going to drive us back towards much bigger dishes, because a 60% signal quality simply wont cut it.

I have a 60”, and could see going to 70”, but beyond that it starts to be a space issue. 80”+ TVs are HUGE - something you ought to have a pretty big room for, which most people don’t have.

How do you back pedal Pythagorus to get an idea what an 84 inch might be in the real world ?

84 = (W²+H²)^1/2   Doesn't help much unless you know the relationship between W & H.

In the case of HD TV the aspect ratio relates screen width (W) and screen height (H) as 16:9 or 1.78:1 which is independent of screen size. This ratio was a compromise between the old 1.33 AR which was utilized by "standard" TV and dates back all the way to the AR of 35MM film. The 1.78 AR was adopted prior to the flat screens now in wide use and was designed to minimize the cost to manufacture HD vacuum tubes. Since vacuum tube displays have virtually disappeared and the choice was locked in to the technical specifications, we are stuck with 1.78 until the "next big thing" in TV hits the scene (holographic displays?).

Why do I say "stuck"? Because 1.78 does not fit any of the aspect ratios currently in use for motion pictures. Original format movies are 1.33, 1.85 "flat", 2.40 (anamorphic), and 2.35 (Panavision). None of these formats will display with out distortion on a 1.78 AR screen. The answer is either to over-scan the picture and clip the parts that don't fit, or to display some black area at top and bottom and both sides.

Since manufactures are no longer constrained by the economics of manufacturing vacuum tubes their flat screen products do not necessarily follow the 1.78 AR rigidly and therefore calculations based on 16/9 should be considered approximations. OK? so hear goes;

We know that 84=(W²+H²)^1/2   and we are guessing the W/H = 16/9 therefore we can say that;
W/H = 1.78 or W = 1.78H further W² = (1.78H)² therefore;
84 = ((1.78H)²+H²)^1/2

H = 84/((1.78² + 1²)^1/2

H = 41.14" and W = 1.78H = 73.23"
Assuming AR = 16/9

Proof:
D =(41.14²+73.23²)^1/2
  = (1692.4996 + 5362.6329)^1/2
  = 83.9948"

PS It took a while to shake the cobwebs out but it's pretty much straight algebra.
