UGREEN HDMI 2.1 Extension Cable 1 m — 8K@60Hz and 4K@240Hz Pass-Through
A 1 m HDMI male to female extension that adds reach to an existing HDMI cable, or saves a hard-to-reach port on a TV or console from repeated plugging. It is built to the HDMI 2.1 bandwidth of 48 Gbps, so it carries 8K@60Hz, 4K@240Hz and 4K@120Hz, with VRR, ALLM, Dynamic HDR and eARC passing through. The cable is triple-shielded under a braided nylon jacket, with 30 AWG conductors and nickel-plated connectors. UGREEN model 40447.
PS5, Xbox Series X and Gaming PCs
When a console or graphics card sits a little too far from the screen, the extension adds 1 m without dropping HDMI 2.1 features: 4K@120Hz or more, VRR to match the frame rate, and ALLM to switch the TV to game mode.
Wall-Mounted TVs and Soundbars
Leave the extension plugged into a wall-mounted TV's port and connect devices to its socket instead, so the TV's own port is not worn out. eARC passes through for a soundbar or AV receiver.
Full HDMI 2.1 Resolution Support
UGREEN's chart shows the 8K HDMI 2.1 extension passing 1080p, 4K@60, 120, 144 and 240Hz and 8K@60Hz, while HDMI 2.0 stops at 4K@60Hz and HDMI 1.4 at 1080p.
48 Gbps Transmission Speed
The bar comparison shows 48 Gbps for HDMI 2.1 against 18 Gbps for HDMI 2.0, the extra bandwidth that high-frame-rate 4K and 8K need.
HDMI 2.1 Gaming Features
Variable Refresh Rate, Auto Low Latency Mode, Quick Media Switching and Quick Frame Transport pass through the extension to a TV that supports them.
Durable and Flexible
The 8K-marked male plug and the UGREEN female socket sit on a braided nylon jacket that UGREEN bend-tested more than 10,000 times.
