In 2012, television manufacturers began focusing on Ultra HD, 4k sets, and at the 2015 Consumer Electronics Show in Las Vegas, the top manufacturers debuted Ultra HD, 4k sets that offer at least four times the detail of 1080p HD.

Missing from CES 2015 is Vizio, the No. 2 TV manufacturer in the U.S. The company announced in February it would not have a showcase at the trade show, which is a surprise considering its 4K TVs have become a popular choice with consumers.

Here are 4k and Ultra HD televisions that debuted at CES 2015 that boast the best eye-dazzling imagery:

LG OLED TVs

LG announced its lineup of organic light-emitting diode (OLED) televisions. These TVs are famed for displaying vibrant colors, deeper blacks and being more energy efficient than liquid crystal displays (LCD).

LG offers seven new OLED sets for sale, including a mammoth 77-inch model (model 77EG9900) which allows the viewer to adjust the display from curved to flat with a button press. The sizes include a 55-inch (model 55EF9500) and 65-inch (model 65EF9500), and an upgraded 65-inch model (model 65EF9800).

Sony X900 C Series 4K TV

Sony's Mike Fasulo showed off the X900 C Series 4K TV that will operate on the Android TV platform. He said the TV is also compatible with Google Cast, Google Play, voice search and Smart Watch. With a width of 0.2 inches, it is the thinnest LCD TV ever made.

Samsung SUHD TV

The South Korean company unveiled a new line of curved SUHD TVs that deliver a crystal clear picture with maximum color via millions of tiny, nanocrystal semiconductors. It is the company's first application of quantum-dot technology screens with crystals that are more than 50,000 times smaller than the width of a human hair. The technology creates sharp, vivid colors and optimal brightness. The smart TV with user interface is based on the Tizen operating system. There are nine screen sizes ranging from 48-88 inches.

Sharp 80-inch AQUOS Beyond 4K Ultra HD TV

Sharp debuted its version of the 4k TV with claims it squeezes more "subpixels" into its set than manufacturers do. The result is a 4k TV with 66 million subpixels instead of the usual 24 million. The company's signature Pixel Splitting technology creates a near-8K (7,680 x 4,320) picture. The impressive set has an improved LED backlight and better upscaling. Consumers can expect the TV to be available with competitive pricing late this year.

As typical for CES announcements, most television manufactures have not yet disclosed prices and availability.
