Cool 49U2 as the newly launched 49-inch 4k TV, also invited the international design community Oscar IF red dot design team to build, 0.59cm extremely narrow frame, highlighting the traditional industry of fine craftsmanship.

Hardware Configuration As a 4K quality 3D smart TV, the screen resolutions of the 2nd generation of the millet and the cool 49U2 TV all reached a resolution of 38402160 and a ratio of 16:9. LeTV S50 Air uses 1080P50 inch soft screen, support 60HZ refresh rate, picture quality and of course, there is a certain gap between the previous two, but in the current 4K film source is not yet popular today, this gap in the picture quality is not obvious .

In this piece of video content, Xiaomi and Cool haven't had much advantage at the beginning. Xiaomi continues to cooperate with ICNTV.

At the same time, the 3D film Sources are also limited to previews, and more and more paid items have been criticized by users who previously purchased Xiaomi TV. LeTV relies on Levi's powerful source library of genuine video clips to provide high-definition film sources. At the same time, it cooperates with many TV stations to buy exclusive online programs to ensure that it can update programs quickly and quickly. CoolTV has cooperated with HuaZhan and ICNTV to compete with LeTV in terms of video quality and quality.
The purchase of LeTV is subject to an audiovisual service fee of RMB 998 for 2 years. This is the mode of LeTV’s profitability for late-stage services through low-priced hardware.
