The more detailed versions of the guidelines matter if you want more than just a basic TV signal: If you play video games at more than 30 frames per second, for example, or you intend to make full use of an HDR TV, or you want an HDMI cable that can also carry data over ethernet (most people do not, but that bandwidth can be used for other things).

For these types of scenarios, you must take refresh rate (measured in cycles per second, stated as Hertz, and abbreviated as Hz), the level of color precision (aka color depth, measured in bits; e.g., 8-bit, 10-bit, or 12-bit), and color data compression (i.e., chroma subsampling) into consideration. The higher you go with refresh rate and bit depth—and the less color data compression you opt for—the more data that will be pushed to your TV.

There are understandably some key similarities between the two, such as image quality, but their differences should not be overlooked. DisplayPort and HDMI cables are intended for different purposes, feature different connectors, and cannot be used interchangeably.

DisplayPort is primarily used on PCs, laptops, and tablets for video transmission. Unlike HDMI, it is very rarely used on consumer electronics. Another key difference is that DisplayPort is subscription-free for producers, whereas HDMI must be licensed by the manufacturer.

An incident where three men allegedly cut an undersea cables raises the question of how vulnerable the world's submarine internet cables are to damage, whether intentional or accidental.

An HDMI cable is just a conduit between your TV and media device, be it a DVD, Blu-ray, or 4K UHD Blu-ray player; media streamer; video game console; or PC. Different types of HDMI cables do exist, but their designations indicate how much data they can carry. (Spoiler: There’s really no such thing as a 4K HDMI cable.)

When pared down to the most basic information, the video resolution guidelines—as set by the HDMI Forum Technical Working Group that defines the specification—are:

Standard HDMI: Up to 720p or 1080i resolution at a 30Hz refresh rate

High Speed HDMI: Up to 4K resolution (including 1080p) at 30Hz

Premium High Speed HDMI: Up to 4K resolution with high dynamic range (HDR) at up to 60Hz

Ultra High Speed HDMI: Up to 10K resolution with HDR at a 120Hz refresh rate (4K video can refresh at up to 240Hz)

The more detailed versions of the guidelines matter if you want more than just a basic TV signal: If you play video games at more than 30 frames per second, for example, or you intend to make full use of an HDR TV, or you want an HDMI cable that can also carry data over ethernet (most people do not, but that bandwidth can be used for other things).
