LG 105-inch, 21:9 Curved Ultra HD TV Debuting at CES

LG is getting a jump on CES 2014 by announcing the 105UB9, a 21:9 aspect ratio, 105-inch curved 4K Ultra HD TV. LG says it's the largest curved TV ever.

Ultra HD TVs are extreme by sheer nature of the new technology, but LG’s new 105UB9 105-inch curved 4K Ultra HD smart LED TV takes extreme to the extreme.

Aside from being really big, it’s also super wide. The 105UB9 is LG’s first 21:9 aspect ratio Ultra HD TV, and it’s curved to making it the largest curved TV ever.

The CinemaScope shape of the TV better mimics the screen shape of most theatrical movies, making it better for true home theater use than a 16:9 aspect ratio TV. Many projection-based home theaters use ultra-wide screens with masking that can move between CinemaScope shape and HDTV shape.

The extra-wide shape also means this TV has more pixels than a standard 16:9 4K TV. The 105UB9 features a resolution of 5120 x 2160

LG says that light uniformity issues were overcome by making improvements to the thin film transistor (TFT) pixel circuit technology to help prevent color leakage and maximize viewing angle. Other curved TVs use OLED technology (this model is an LED LCD TV) which offers great viewing angles due to the fact that it doesn’t require backlighting.

More information on the 105UB9 105-inch Ultra HD TV will be revealed at CES in January, but we can assume it includes the same smart TV features of other LG models, including the magic remote with voice and gesture control. The TVs speakers are integrated into the base.

Wow…just read about an almost identical set being shown from Samsung.  I get the feeling that these two companies are in a “anything you can do, I can do better” type of rivalry.

Curved TVs are stupid. Anyone who wants a curved TV hasn’t actually watched one for any considerable amount of time. They are disorienting when viewed from a steep angle and when there is glare, it is made much worse because of the curve.

And the 21:9 aspect ratio is just ridiculous. That guarantees you will have black bars either on the top or sides of everything you watch unless you zoom/crop the image or distort it by stretching or squishing it. These are possibly the dumbest TVs made in the past decade. What a waste of effort.

The exception of course, is if you primarily watch movies, most of which have been produced in roughly a 2.35:1 A/R for the past decade or so. Poof! No more black bars….

I see you point on the curved TV (the screen would have to be considerably larger for that to be necessary) but I believe you are overlooking the fact that the 21:9 aspect ratio is a new resolution that is supported by HDMI 2.0.

In fact, the 21:9 aspect ratio guarantees we will NEVER see the top and bottom black bars we all live with on 16:9 sets since both 16:9 and 21:9 (basically anamorphic 2.39:1) content will fill the full height of the screen without any stretching, zooming, or hocus-pocus! The viewer will be able to watch 2.39:1 video using every pixel available and will have black bars on the far left and right side of the screen when watching 16:9 content. The side black bars will not be as distracting as top/bottom black bars since will be in our peripheral vision. One feature I would love to see in these new wide screen sets is pixel blanking or video masking to eliminate any light that may come from these side black bars.

The 2.39:1 aspect ratio has been our design of choice in front projection viewing areas for years now because of these benefits. It’s about time someone has decided to make a HDTV that is suitable for all of the aspect ratios we watch regularly!

It’s a gimmick. Press people eat it up. Today I got this announcement: “Massive Audio Unveils Worlds Loudest & Largest Portable Bluetooth Speaker @ CES 2014!”

Ok, now we REALLY need to get the interior designer involved.  A HUGE curved TV that does not hang on the wall or hide in the wall will require a rather large stand for it to sit on.  The base appears to be silver in color, so it will stand out ever so nicely in the room.  The interior designers will absolutely LOVE IT!!

Julie, our business has always endured silly gimmicks.  Eventually they become the butt of some joke.

Entertainment content is either TV based (everything that originates in video) or movie based. Movies, which are considered an American art form (see National Film Registry for example), are 1.33:1 (mostly pre-1950’s), or widescreen which since the 1950’s were either 1.85:1 or 2.35:1. The 21x9 format was made for movies and if implemented well, becomes a cinema style display showing all content at the same height, with no letterboxing or overscan, only the width changing based on the artistic format. That’s how the best movie houses have always done it. That’s how the best home cinema designs have been built since Runco introduced Cinewide in 2003 (got a Technical Emmy for their AR control of cinema content at CES 2013 just this year for work they began 20 years ago!). The problem with 21x9 TV’s to date (Philips, Vizio) has been implementation. I use the 58” Vizio (yes, I’m the guy who bought one) as a cinema format monitor flanking my several times larger front projection scope screen. But their aspect ratio control is atrocious with an auto detect mode, and greatly distorted stretch modes we would never accept in a real theater. However, when you pick the right content and show it on a true scope format display, even a small one, the magic of that artistic format makes it something special. Five years ago Runco International introduced a flush mount 21x9 TV of about the same size as the 105” LG, based on DLP technology. It was hidden behind a curtain and unveiled as a surprise to a room of about 150 dealers at CEDIA. To this day it is the only product I’ve seen unveiled like this that got an unprompted standing ovation. It had the uniformity and image accuracy of DLP, and the cool room aesthetic of a scope format TV, with none of the image quality problems of ordinary TVs (relative to cinema standards). I hope LG’s implementation is better than Vizio’s, which caused them to sell none and then drop it after only one tiny production run. The Runco CinemaWide TV unfortunately had a $50k retail, which was out of touch with the practical realities of the market for even a very cool TV back then…but we sold a few, and it was very, very cool. And isn’t ‘cool’ what we seek out for our clients? Now curving a flat panel? That might be a case of style over substance, time will tell. Cheers, & Merry Christmas to cinema designers everywhere:-)
