Features

Shielded From the Inside Out

Solid copper conductors, individual foil wraps on each pair and a tinned-copper braid keep interference from power cords and Wi-Fi off the signal.

Seats Firmly, Bends Gently

The aluminum plug locks into the HDMI 2.1 port with an 18N grip, while the flexible neck makes a 32mm turn inside a 1.5-inch wall gap.

Full Bandwidth, First Try

Your TV and source agree on 4K 120Hz, VRR, Dolby Vision and eARC Atmos in under a second, with no flicker and no lip-sync drift.

Zero Bit Errors in 72 Hours
It held a full 48Gbps link for three days on a professional analyzer, including hours under heavy interference.
Dolby Vision and eARC Atmos
It passes Dolby Vision 4K 4:4:4 to your TV and uncompressed Atmos to your soundbar, and the handshake stays locked when you switch inputs.
48Gbps Zero-Blackout Core
Solid 30AWG tin-plated oxygen-free copper carries a full FRL6 link (12Gbps × 4 lanes), so 4K 120Hz, HDR and VRR can run together without dropouts.

How to use it

1
Uncoil and Uncap
Unwind the cable and pull the clear caps off both gold-plated ends.
2
Plug Into the 2.1 Port
Seat one end in your TV's HDMI 2.1 or eARC input and the other in your console, PC or soundbar. Either end works either way.
3
Turn It On and Play
Enable enhanced HDMI mode on that input, then confirm 4K 120Hz, VRR and HDR in your source's display settings.

In the box

1 × Cosari HyperLink 48G 6.6ft (2m) braided HDMI 2.1 cable
1 × pair of clear protective connector caps
1 × reusable silicone hook-and-loop cable strap

Care & safety

Hold the aluminum shell, not the braid, when unplugging, and pull straight out to protect both the cable and your device's port.
Keep bends at or above the 32mm radius, and fit the clear caps if you store the cable so dust stays off the gold contacts.

Questions

Does the Cosari HyperLink 48G support 4K 120Hz/144Hz with VRR and ALLM at the same time?

Yes. It carries the full 48Gbps HDMI 2.1 bandwidth, so 4K at 120Hz or 144Hz, 10-bit RGB 4:4:4, HDR, VRR and ALLM can all run at once. We confirmed this on a PS5 Pro, an Xbox Series X and an RTX 4090 connected to an LG C4.

Will it work with eARC for Dolby Atmos and DTS:X?

Yes. Plug it into your TV's eARC port and it passes uncompressed Dolby Atmos and DTS:X to soundbars and AV receivers, including the Sonos Arc and Bose models.

Is it backwards compatible with older HDMI devices?

Yes. It works with HDMI 2.0 and 1.4 ports on devices like the Nintendo Switch, PS4, Fire TV Stick and 1080p or 4K60 monitors. Those devices will run at their own maximum settings.

Is the cable directional?

No. Both ends are identical, so either end can go into the TV or the source device.

Will the connector fit in tight or recessed ports?

The aluminum shell is 19.5mm wide and 10.2mm thick, which is slim enough to sit side by side with other plugs on recessed TV panels and graphics cards.

Is 6.6 feet long enough for a wall-mounted TV?

For most setups, yes. 6.6ft (2m) reaches from a low media console to a wall-mounted TV with some slack, and it is short enough to carry full 48Gbps passively with no signal loss.
