Online streaming services such as Netflix and Amazon Prime Video launched videos in 4K resolution in 2014 [3] and are actively expanding their collection of videos in 4K resolution. As 4K content becomes more common, the usefulness of 5K displays in ...
Also known as Category 3 HDMI or "Ultra High Speed" HDMI, the cable is designed to support the 48 Gbit/s bandwidth of HDMI 2.1, supporting 4K, 5K, 8K and 10K at 120 Hz. [82] The cable is backwards compatible with the earlier HDMI devices, using existing HDMI type A, C and D connectors, and includes HDMI Ethernet.
It is therefore possible to run at 4K 144 Hz using the HDMI interface. If that's what you mean by "support" then yes, HDMI 2.1 supports 4K 144 Hz. HDMI allows any arbitrary video format, as long as it is within the restrictions of the HDMI Specification, such as the maximum aggregate bit rate of 48 Gbit/s. This is established in section 6 of ...

The CEA definition does allow manufacturers to use other terms—such as 4K—alongside the Ultra HD logo. [4]: 9 Since the resolution in CEA's definition is only a minimum requirement, displays with higher resolutions such as 4096 × 2160 or 5120 × 2880 also qualify as "Ultra HD" displays, provided they meet the other requirements.
Earlier versions of HDMI, such as HDMI 1.1, support PCM audio, where the player decodes the audio and transmits it losslessly as PCM over HDMI to the receiver. Some receivers and players support analog surround sound, and the player can decode the audio, and transmit it to the receiver as analog audio. Most receivers and players support S/PDIF.
Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
