Answer: The full name of EDID is Extended Display Identification Data (extended display identification data), a total of 128 bytes. It contains parameters about the monitor and its capabilities, including vendor information, maximum image size, color settings, factory presets, limits on frequency ranges, strings for monitor name and serial number, and more. Figuratively speaking, EDID is a collection of ID cards, household registration books, skill certificates and other documents on the display. The purpose is to tell others who I am, where I come from, and what I can do.

A: In order to allow PC or other image output devices to better identify the display properties

Answer: RGB is a color representation, generally 24 bits are used in the computer to store, and each color occupies 8 bits. Many LCD displays support RGB24

A: There are two main reasons for the emergence of a color representation, YUV, one is to make the color signal compatible with black and white TV sets, and the other is to reduce the transmission bandwidth. In YUV, Y represents luminance, and U and V represent chrominance. There are also many YUV formats, but the common ones are 422 and 420 formats.

Answer: H.264, MPEG-4, MPEG-2, etc. are all compression algorithms. The biggest advantage of H.264 is that it has a high data compression ratio. Under the same image quality, the compression ratio of H.264 is More than 2 times that of MPEG-2, and 1.5 to 2 times that of MPEG-4. H.264 has high quality and smooth images while having a high compression ratio. For example, for mobile TV, the image signals we receive are generally in H.264 format.

Answer: "YUV444 = bandwidth*1 YUV422 = bandwidth*2/3 YUV420 = bandwidth*1/2"

A; ARC's full name in English is Audio Return Channel, and Chinese is Audio Return Channel. Its function is to transmit sound signals. Specifically, on the HDMI interface that supports ARC, the TV can send the audio signal back to the audio device with HDMI ARC function through the HDMI cable through ARC, which can save a separate digital output wire.

Answer: "The difference between 2.4G: 2.4G transmission is farther, and the band frequency is relatively short, so it can be received in very far places, but the disadvantage is that it is unstable and easy to be interfered. Even if it is full, the network may be very poor. slow.

5G difference: It has a higher wireless transmission rate, stronger anti-interference, stronger wireless signal, higher stability, and is not easy to drop. The disadvantage is that the wavelength band is long, the transmission distance is short, and the penetration is poor. But it will be stable within the effective distance. "
