LAS VEGAS: HARDWARE VENDORS Samsung, Sony, LG and Toshiba are a few of the major players attending the Consumer Electronics Show (CES) this week that have added Ultra High Definition (UHD) TVs to their lines of products.

UHD includes both 4K UHDTV, which has a 2160p signal format with 3840x2160 resolution - four times the pixels of HD 1080p - and 8K UHDTV, which has a 4320p signal format with 7680x4320 resolution - 16 times the pixels of existing HD 1080p TVs.

Pixels in UHD are so small that they are almost invisible on TV sets and as a result the format has the level of detail seen in 70mm IMAX movies.

As a trend that has spawned TV announcements across the CES trade show floor this week, UHD is likely to become the norm, built into mainstream TV sets seen in the home over the next few years. However, there isn't much UHD content available yet, so those intrested in buying a TV set will have to wait while the movie and television industries catch up.

One of the first to reveal its UHD televisions at CES this year was Toshiba, announcing a flagship L9300 84in UHD TV, which is set to be joined by two other 4K models in 65in and 58in sizes later this year.

All of the Toshiba models will feature an ultra-slim bezel with gun metal trim and stand. Powering the ultra-high resolution video is Toshiba's CEVO 4K quad and dual core processor, which also helps upscale the content. It also has Toshiba's Clearscan 240Hz refresh rate for smoother fast motion video.

Next up, LG unveiled two UHD TVs to add to the firm's 4K range, which already features an 84in model. These include the new 55in 55LM90V and 65in 65LM90V models.


These two new TVs come with all the latest functions, including Smart TV, HbbTV, motion interpolation and a passive 3D mode with Dual View functionality for full-screen two-player gaming. The TVs will also ship with four pairs of 3D glasses and LG's Magic Remote motion controller, which works like a Nintendo Wiimote. LG hasn't announced pricing or release dates for these new UHD TVs.

Japanese TV maker Sony also expanded its Bravia 4K UHD XBR LED TV lineup with 65in and 55in models.

Both are WiFi enabled and can tap into various Sony Smart TV features, like linking with mobile devices and sharing content via NFC.

Sony said the X series of 4K LED TVs will be available this Spring at Sony Stores, however it has not announced pricing yet - though we expect that they won't come cheap.

Korean electronics firm Samsung also showed off an upgrade to its TV lineup at CES this year, the S9 UHD TV, which is available with a 4K 85in or whopping 110in display.

This UHD television has a host of new features, such as a proprietary up-scaling engine that can up-convert HD or Full HD content to UHD level picture quality. Along with this there is also Samsung's Precision Black Pro technology, LED dimming and a high contrast ratio.

This is all bundled within a strangely shaped chassis that's different than most televisions on the market now, though it's probably not to everyone's tastes.

As with the rest, Samsung also has failed to provide us with any release date or pricing information. µ
