For consoles such as PS5 and Xbox Series X, the relevant maximum gaming mode is generally up to 4K@120Hz where supported. Higher modes such as 4K@144Hz or 240Hz are intended for compatible PC and display configurations.

Dynamic HDR

The UGREEN 70321 supports Dynamic HDR, allowing compatible source devices and displays to transmit dynamic HDR information for enhanced presentation of supported HDR content.

This is useful for:

• HDR Gaming
• UHD Movies
• Streaming
• OLED / QLED TVs
• Home Theater
• High-resolution media

The final HDR quality depends primarily on the capabilities of the source, content, and display.

eARC Audio Support

eARC (Enhanced Audio Return Channel) provides high-bandwidth audio connectivity between compatible TVs and audio equipment.

It is particularly useful when connecting:

• TVs
• Soundbars
• AV Receivers
• Home Theater Systems

With compatible equipment, eARC can carry advanced high-quality audio formats over HDMI.

Dolby Audio Support

The UGREEN 70321 supports HDMI transmission of Dolby audio formats when used with compatible source devices and audio equipment.

This makes it suitable for gaming, UHD movies, Blu-ray playback, streaming, and home-theater applications.

3D Video Support

The cable also supports 3D video transmission, allowing compatible source devices and displays to handle supported 3D content.

Nylon-Braided Construction

The UGREEN 70321 features a braided outer jacket designed to improve durability and resistance to everyday bending, pulling, and tangling.

This makes it suitable for gaming desks, entertainment centers, and frequently used AV setups.

Zinc-Alloy Connector Housing

The connectors feature a durable zinc-alloy shell, providing additional protection around the HDMI connector housing and helping improve overall cable durability.

Steam Deck & Nintendo Switch Note

The Steam Deck itself does not have a full-size HDMI port, so an appropriate dock or USB-C-to-HDMI adapter is required.

Similarly, a standard Nintendo Switch uses HDMI through its dock. The cable's 8K/high-refresh capabilities do not increase the maximum video-output capabilities of either device.

MacBook Pro Compatibility

Compatible MacBook Pro models with a built-in HDMI port can connect directly.

MacBook models with only USB-C/Thunderbolt ports require a suitable USB-C/Thunderbolt-to-HDMI adapter or dock.

The maximum output resolution and refresh rate depend on the specific MacBook model.

Important Note

To achieve high-end modes such as 8K@60Hz or high-refresh 4K, the complete connection must support the required video mode:

Compatible Source → UGREEN 70321 → Compatible Display

The cable cannot increase the resolution or refresh-rate capability of a console, graphics card, dock, TV, or monitor.

For example, connecting a Nintendo Switch through this cable does not make the Switch output 8K, and using it with a 4K@60Hz TV will still limit the final output to the capabilities of that TV.
