New TVs

Samsung says its latest Smart TVs will be able to detect finger-based gestures

Televisions are always one of CES's biggest categories, right back to its first show in 1967.

The two biggest manufacturers - Samsung and LG - will square off once again at this year's event with similar sounding products.

Both have already announced 105in (267cm) sized 4K Ultra HD screens in the extra-widE 21:9 aspect ratio.

• Japan's Sony, Sharp, Toshiba and Panasonic will also have new Ultra HD models on show, as will China's HiSense and TCL Corp. But the firms are expected to pursue different strategies.
• "The Chinese manufacturers are pushing 4K as a common technology in a lot of their models, while the Japanese and Korean brands are still looking for it to be more of a premium feature," explains Edward Border from the consultancy IHS Technology.

• Move-Eye allows older TVs to accept gesture controls
• "So, for some brands you will mainly see 4K at the higher-end, but for others it could appear in high 30in and low 40in sets."
• Polaroid's decision to sell a 50in Ultra HD set for less than $1,000 could also be disruptive.
• Watch out too for third-party add-ons that transform older sets into "smart TVs".
• For example Bob is an Android-powered stick that plugs into an HDMI port to offer YouTube and video games.
• And Tarsier will demo special glasses called Move-Eye that monitor the wearer's hand movements, allowing them to switch channels using gesture controls.
