The advantage in range remains strong as the video quality gets lower. At 4K and 30Hz, you can reach 20 meters in both directions, or 66 feet. That’s a total range of over 130 feet. And at 1080p and 60Hz, you can reach 30 meters in both directions, or a total range of about 200 feet. That’s four times the range of a standalone HDMI cable.
That's fine for the average living room setup, connecting your new Xbox Series X, PS5, or RTX 3000/4000 graphics card to your HDMI 2.1 TV, but you'll need an active cable to go further if you want to maintain the full 48Gbps bandwidth of HDMI 2.1. HDMI cable length for active HDMI 2.1 connections can increase dramatically whilst retaining full

In order to minimize signal loss and maintain placement flexibility, experts recommend keeping hdmi cable lengths below 20 feet. However, the maximum reliable length for passive hdmi cables that still maintain good signal transmission is generally considered to be 25 feet.

DisplayPort 1.0 gives a maximum of 8.64 Gbit/s over a 2-meter cable, whilst DisplayPort 1.1 gives the same speed while adding the ability to allow devices to implement alternative link layer and allowing for much longer lengths between the source and display.

HDMI 2.1 raised the HDMI bandwidth to 48Gbps, enabling it to handle the demands of modern gaming with support for higher resolutions of up to 8K, faster refresh rates of up to 120Hz in 4K, and
The maximum effective length for a 4K HDMI cable can vary, but for optimal signal quality, it’s generally advisable to keep standard copper HDMI cables up to 3 meters. For longer distances, specialized solutions like active HDMI cables or fiber-optic HDMI cables can extend the reach up to 25 meters (approximately 82 feet) without sacrificing mxYoe.
