HDR
Automatically provide an optimal HDR effect based on the video source.
If an HDR signal has been processed by some devices (graphics card/player, etc.), the signal will not 
output any HDR metadata and thus will not be recognized as an HDR signal. In this case,  Local Dimming 
needs to be enabled manually so as to ensure optimal HDR effects.
The HDR (High Dynamic Range) technology implements video images that are very similar to the images 
seen through human eyes by finely adjusting the contrast of the source.

logo, the HDR effect can be enabled.
3 When the Xbox One S plays a Microsoft Xbox HDR game or a UHD Blu-Ray disc with the UHDA (or 
HDR) logo, the HDR effect can be enabled.
4 When PS4/PS4 Pro plays a Sony PS HDR game, the HDR effect can be enabled.
 ― For information about the Xbox One S/PS4 (Pro) games that support HDR, visit the official Xbox/PS4 
websites.

Horizontal Frequency
The time required to scan a single line from the left to the right side of the screen is called a horizontal cycle. The reciprocal number of a horizontal cycle is called horizontal frequency. Horizontal frequency is measured in kHz.
 ― Vertical Frequency
Repeating the same picture dozens of times per second allows you to view natural pictures. The repeat frequency is called "vertical frequency" or "refresh rate" and is indicated in Hz.
 ― This product can be set to only one resolution for each screen size to obtain the optimum picture quality due to the nature of the panel. Using a resolution other than the specified resolution may degrade the picture quality. To 
avoid this, it is recommended that you select the optimum resolution specified for your product.
