On MWC event last January LG introduces Wireless Ultra HD Transmission Technology. This technology allows multimedia content in a smartphone sent on TV at faster speeds with smoother results. Even its technology claimed to be able operate better than the video compression technology and data transfer which previously already known.
By minimizing the existence of barriers such as lag and loss of data during the transmission takes place, this technology uses WiFi as connection. During the transfer, multimedia content will automatically adjust with resolution on the TV screen receiver to produce a perfect visual. The specialty technology from LG Wireless Ultra HD Transmission exists on a smaller power requirements. The latest technology from this LG only needed half of the power that needed other multimedia transmission technologies.
What is 4K?
Technically, 4K shows a very specific screen resolution of 4096 x 2160. Although many people use 4K to refer on each resolution screen that has 4000 horizontal pixels.
Ultra HD has a little lower resolution from it, which is equal to 3840 x 2160. And it was four times higher than full HD resolution of 1920 x 1080. Many film cameras now have over 4K resolution, such as Epic RED which has 5K resolution of 5120 x 2700 and Sony F65 which has resolution of 8K or at 8192 x 4320.
