Released a new format of HDMI 2.0a. The new format HDMI 2.0a was a change in the communication protocol, which means that all cords and existing ports will be able to maintain it without the need to replace them.
The only condition, changes in device software ports HDMI 2.0.
The difference between the new standard HDMI 2.0a only affects video with support for HDR (High Dynamic Range).
HDR allows you to make the image more realistic in practice, this happens as when shooting video shoot multiple frames of video but with different exposures, then compares the frame and several frames recorded one but with good quality, best portrayal of shadows and dimming on highly bright areas. Since it is necessary to convey more information about the video data portion of the image is recorded as additional data.
When viewing the HDR video than a standard video and metadata to be transmitted to the brightness …
If the TV does not have support for HDR only port HDMI 2.0, and the video is transferred to the HDR metadata can not be read correctly applied to the video, we see a standard video.
The main condition for viewing video HDR has support for both HDMI devices 2.0A.
It should also be borne in mind that technical standard TVs can not display HDR video as the need to support at least in 10bit color depth and thus good screens to show the video.
Therefore, the TV screen IPS, and VA are usually no support for HDR. Support for HDR implemented in TVs with OLED screens or quantum dots.
