8K@60Hz and 4K@120Hz

The UGREEN 40181 supports high-resolution entertainment and high-refresh-rate gaming with compatible HDMI 2.1 equipment.

*Actual resolution, refresh rate, HDR format and color depth depend on the source, HDMI ports, display and settings. Shared family pages sometimes advertise 4K@240Hz, but exact 3-meter 40181 listings consistently document 4K@120Hz as its high-refresh 4K mode.

48Gbps HDMI 2.1 Bandwidth

HDMI 2.1 bandwidth up to 48Gbps provides the capacity needed for 8K video, 4K high-refresh gaming and advanced digital audio.

This makes the cable suitable for:

• 8K@60Hz video
• 4K@120Hz gaming
• PlayStation 5/PS5 Pro
• Xbox Series X|S
• Gaming PCs
• NVIDIA GeForce RTX graphics cards
• AMD Radeon graphics cards
• 8K and 4K televisions
• OLED and QLED gaming TVs
• High-refresh gaming monitors
• Advanced home-theater equipment

4K@120Hz Gaming

Support for 4K at up to 120Hz makes the UGREEN 40181 suitable for modern gaming systems.

Compatible equipment can include:

• PlayStation 5/PS5 Pro
• Xbox Series X|S
• Gaming PCs
• 4K 120Hz gaming monitors
• OLED gaming televisions
• QLED gaming televisions
• NVIDIA and AMD graphics cards

Both the source and display must support 4K@120Hz through their selected HDMI ports.

VRR and ALLM

Variable Refresh Rate

VRR allows compatible gaming systems and displays to synchronize refresh behavior dynamically, helping reduce:

• Screen tearing
• Stuttering
• Uneven frame presentation
• Motion disruption

Auto Low Latency Mode

ALLM allows a compatible display to switch automatically to a low-latency mode when gaming content is detected.

These functions must be supported and enabled on both the source and display.

QMS and QFT

Quick Media Switching

QMS can reduce blank-screen interruptions when compatible equipment switches between different video frame rates.

Quick Frame Transport

QFT reduces frame-transport time between compatible sources and displays, potentially improving gaming responsiveness.

Dynamic HDR, HDR10+ and Dolby Vision

The UGREEN 40181 supports advanced HDR signal transmission, including Dynamic HDR, HDR10+ and Dolby Vision.

These formats can provide improved:

• Brightness
• Contrast
• Color reproduction
• Highlight detail
• Shadow detail
• Scene-by-scene image presentation

The source, content and display must support the selected HDR format.

eARC Audio Support

Enhanced Audio Return Channel provides greater audio bandwidth than standard ARC and supports advanced home-theater audio formats between compatible televisions, soundbars and AV receivers.

Advertised format support includes:

• Dolby Atmos
• Dolby TrueHD
• DTS-HD Master Audio
• DTS:X
• Uncompressed multichannel audio
• Object-based surround sound

eARC must be supported and enabled on the connected television and audio system.

HDMI Ethernet Channel and CEC

HDMI Ethernet Channel

Allows compatible HDMI devices to exchange network data without a separate Ethernet cable between them.

Consumer Electronics Control

CEC allows compatible devices to control selected functions of other HDMI-connected equipment, including power, volume and input selection.

Availability depends on the connected equipment and its configuration.
