Overview
A 6.6 foot braided HDMI cable rated for 8K at 60Hz and 4K at 120Hz, aimed at gamers and home theater setups that need eARC and HDR support between a console or PC and a modern TV or monitor.
Acer's cable is built around the full HDMI 2.1 spec rather than the older, slower 2.0 pinout, so the 48Gbps bandwidth is real rather than a label carried over from an HDMI 1.4 cable. The main caveat is length: at 6.6 feet it suits a desk or console setup better than a wall mounted TV run, where a longer cable would be needed.
- 48Gbps HDMI 2.1 bandwidth
- 8K at 60Hz and 4K at 120Hz
- EARC and ARC audio return
- Braided jacket with aluminum connector shells
Who it's for
Anyone connecting a PS5, Xbox Series X or a gaming PC to a TV or monitor that supports 4K at 120Hz or 8K at 60Hz will get full use of this cable. It also fits home theater setups that route audio back to a soundbar over eARC. Buyers who only need basic 1080p or 4K at 60Hz do not need the extra bandwidth.
Strengths and trade-offs
Drawn from this product's published specifications.
- Full 48Gbps bandwidth for 4K at 120Hz and 8K at 60Hz
- EARC support for lossless audio to a soundbar
- Backward compatible with older HDMI 2.0 and 1.4 gear
- 6.6 feet is short for a wall mounted TV run
- No listed VRR certification detail beyond general support
Performance notes
The cable's 48Gbps ceiling is what actually enables 4K at 120Hz and 8K at 60Hz signals to pass without dropping frames or falling back to a lower resolution. HDCP 2.2 support matters for streaming apps and 4K Blu ray players that refuse to output picture without it. The braided jacket and aluminum shell mainly protect against connector wear and cable memory rather than changing signal quality, since HDMI is a digital, error checked format.
