8K@60Hz and 4K@120Hz

The UGREEN 40178 provides the bandwidth required for high-resolution video and high-refresh-rate gaming.

*Actual resolution, refresh rate, HDR format and color depth depend on the source, HDMI ports, display and content. Some recently updated regional listings additionally advertise 4K@240Hz for SKU 40178, but 4K@120Hz is the consistently documented mode for the original HD150 version.

48Gbps HDMI 2.1 Bandwidth

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

This makes the cable suitable for:

• 8K UHD 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 monitors
• Home-theater equipment

4K@120Hz Gaming

Support for 4K at up to 120Hz makes the UGREEN 40178 suitable for modern gaming systems.

Compatible equipment can include:

• PlayStation 5/PS5 Pro
• Xbox Series X|S
• Gaming PCs
• NVIDIA GeForce RTX GPUs
• AMD Radeon GPUs
• 4K 120Hz gaming monitors
• OLED gaming televisions
• QLED gaming televisions

The console or computer and display must both support 4K@120Hz through their selected HDMI ports.

VRR and ALLM

The cable supports HDMI gaming technologies including VRR and ALLM.

Variable Refresh Rate

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

• Screen tearing
• Stuttering
• Uneven motion
• Input disruption

Auto Low Latency Mode

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

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

QMS and QFT

Quick Media Switching

QMS helps compatible equipment switch between video modes with reduced blank-screen interruption.

Quick Frame Transport

QFT can reduce transport latency between a compatible source and display, helping improve responsiveness during gaming.

Dynamic HDR, HDR10+ and Dolby Vision

The UGREEN 40178 supports the transmission of advanced HDR formats, including Dynamic HDR, HDR10+ and Dolby Vision.

These formats can provide enhanced:

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

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

SBTM Support

Source-Based Tone Mapping allows compatible source devices to perform part of the HDR tone-mapping process before sending the image to the display.

This may improve HDR presentation when both the source and display support the feature.

eARC Audio Support

eARC provides greater audio bandwidth than standard ARC and supports advanced home-theater audio formats with compatible televisions, soundbars and AV receivers.

Advertised audio support includes:

• Dolby Atmos
• Dolby TrueHD
• DTS-HD Master Audio
• DTS:X
• 5.1-channel audio
• 7.1-channel audio
• Uncompressed multichannel audio

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

HDMI Ethernet and CEC

The cable supports HDMI Ethernet Channel and Consumer Electronics Control.

HDMI Ethernet Channel

Allows compatible HDMI devices to share a network connection without a separate Ethernet cable between them.

CEC

Allows compatible HDMI-connected equipment to control certain functions of other devices, such as power, volume and input selection.

Feature availability depends on the connected equipment.

Durable Braided Construction

The cable features a flexible braided exterior designed to improve resistance to bending, abrasion and everyday wear.

Its construction includes:

• Braided outer jacket
• Protective PVC layer
• Copper conductors
• Multiple internal shielding layers
• Reinforced connector strain relief
• Corrosion-resistant HDMI contacts

The short 1-meter length is particularly convenient for nearby equipment and helps minimize excess cable behind a television or gaming desk.
