8K@60Hz and 4K@120Hz

The UGREEN 80401B provides the bandwidth required for UHD video and high-refresh-rate gaming.

*The available resolution, refresh rate, color depth and HDR format depend on the source, HDMI ports, display and content. Some recently updated regional pages advertise 4K@240Hz for base model 80401, but 4K@120Hz is the consistently documented maximum for the original HD140 revision.

48Gbps HDMI 2.1 Bandwidth

HDMI 2.1 bandwidth up to 48Gbps provides the capacity required for demanding display and audio formats.

This makes the cable suitable for:

• 8K@60Hz video
• 4K@120Hz gaming
• PlayStation 5
• 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-rate gaming monitors
• Home-theater equipment

4K@120Hz Gaming

Support for 4K at up to 120Hz makes the UGREEN 80401B suitable for compatible modern gaming platforms.

Compatible equipment can include:

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

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

VRR and ALLM

Variable Refresh Rate

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

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

Auto Low Latency Mode

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

VRR and ALLM must be supported and enabled on the source and display.

QMS and QFT

Quick Media Switching

QMS helps compatible equipment switch between different video frame rates with reduced blank-screen interruption.

Quick Frame Transport

QFT reduces the time required to transport individual frames between compatible equipment, potentially improving gaming responsiveness.

Dynamic HDR, HDR10+ and Dolby Vision

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

These formats can provide improved:

• Contrast
• Brightness
• Color reproduction
• Highlight detail
• Shadow detail
• Image depth

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

eARC Audio Support

eARC provides increased audio bandwidth compared with standard ARC and supports advanced audio formats between compatible televisions, soundbars and AV receivers.

Supported formats can include:

• Dolby Atmos
• Dolby TrueHD
• Multichannel PCM
• High-resolution surround sound
• Other object-based audio formats supported by the equipment

eARC must be supported and enabled across the connected television and audio equipment.

HDMI Ethernet Channel and CEC

HDMI Ethernet Channel

Allows compatible HDMI equipment to share a network connection without requiring a separate Ethernet cable between those devices.

Consumer Electronics Control

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

These functions depend on the capabilities and settings of the connected devices.

Premium Shielded Construction

The UGREEN HD140 is designed for stable signal transmission and improved physical durability.

Its construction includes:

• Oxygen-free copper conductors
