The different types of HDMI and HDMI cables are:

HDMI Versions

HDMI 2.0 – Known for its 4K capability and can run at 60Hz at 4K output as well as 120Hz at 1080P, without any frame stutter or lags, also support backward linking and bandwidth up to 18Gbps.

Most HDMI 2.0 cables have the capacity of displaying up to 15 to 25 feet length of the cable after that they show a reduction in Quality. Whereas fiber optic HDMI cables have a significantly longer range. Fiber optic HDMI cables typically have a range of 50 to 200 feet.

HDMI 2.1 – Also known as 8K ready, or 8K capable bandwidth cable it supports bandwidth up to 48Gbps and is capable of running at 4K 120Hz as well as compaitable with an older generation of HDMI.

HDMI 2.1 cables only support lengths of up to 50 feet, after which the signals start to degrade.

HDMI Cable Types

The Standard Cable– These cables come standard with TVs and DVDs with an output range of 720p to 1080p with bandwidth upto 5 Gbps .

Premium High Speed-These cables pack some power in them as they are built to handle 4K/UHDR resolution upto 60-120 Hz and 8K 30Fps with bandwidth speeds upto 18-48 Gbps depending upon your HDMI version.

What Factors Affect the Length of an HDMI Cable Run?

When it comes to HDMI cable length and how far can you run it, there are some factors which you should check before extending the capacity.

  1. The first is the gauge length of the wire. The thicker the wire, the longer it can travel without losing signal .
  2. The second factor is the type of cable. There are two main types of HDMI cables: standard, high-speed, and ultra-high-speed. Standard cables are only meant for runs up to 15-20 feet, also it depends upon the HDMI technology whether it is HDMI 2.0 or 2.1.
  3. The third factor is the resolution that you’re trying to achieve. For 1080p resolutions, you can run the cable up to 20 feet without any issues. But for 4K resolutions, you should keep the length under 20 feet, reason being 4K resolution needs higher bandwidth and with higher length quality depreciates.

So, when it comes to figuring out how far your HDMI cable can run, it usually depends on a few factors. But as a general rule of thumb, you should not go beyond 20 feet for the sake of picture quality and frame rates. The shorter the cable, the better output will be produced.
