What it is

This 3-pack of Certified Ultra High Speed HDMI cables delivers 48 Gbps bandwidth as defined by the HDMI 2.1 standard. Each 6.6 ft cable supports 8K resolution at 60 Hz, 4K at 240 Hz and HDR formats including Dolby Vision. They are built for gamers and home-cinema users who need reliable 8K connectivity.

Deciding specification

The 48 Gbps certified bandwidth is the single figure that determines whether the cable can carry uncompressed 8K 60 Hz or 4K 240 Hz signals. Without this certification a cable may fall back to lower colour depth or refresh rates, so the Ultra High Speed logo is the go/no-go test for 8K gear.

Capacity and headroom

The cables handle 8K 7680 × 4320 at 60 Hz, 4K at 240 Hz, 1440p and 1080p with 4:4:4 RGB HDR 12-bit colour and 32 audio channels at 1536 kHz. They run out of headroom for any resolution or refresh combination that exceeds the 48 Gbps ceiling such as 8K above 60 Hz or 4K beyond 240 Hz.
