The UGREEN CM800 6-in-1 Steam Deck Dock (75126) is a versatile USB-C docking station designed to expand the connectivity of handheld gaming consoles such as the Steam Deck, Steam Deck OLED, ROG Ally, ROG Ally X and Lenovo Legion Go.

Its HDMI 2.1 output supports up to 4K@120Hz, along with VRR, FreeSync and G-Sync compatibility when the connected host, display, cable and software support those technologies. The dock also provides 100W PD input and up to 85W power delivery to a compatible host, making it suitable for high-performance handheld gaming setups.
The dock includes two USB-A 3.0 ports and one USB-C 3.0 data port, all supporting up to 5Gbps, plus a Gigabit Ethernet port for stable wired networking. Its foldable aluminum-alloy stand and detachable USB-C host cable make it convenient for both desktop gaming and travel.
Common Problems with Handheld Gaming Devices
Handheld gaming consoles are convenient and portable, but their built-in ports may limit desktop-style gaming setups.
Common limitations include:
- Limited USB ports
- No full-size HDMI connection
- Lack of wired Ethernet
- Limited charging connectivity while using accessories
- Difficulty connecting multiple peripherals
- No convenient stand for desktop gaming
- Limited display connectivity
- Cable clutter around the gaming setup
A dedicated docking station can turn a handheld console into a more complete desktop or living-room gaming system.
Smart Solution for Handheld Gaming
The UGREEN CM800 6-in-1 Steam Deck Dock combines essential connectivity into one compact docking station.
Connect your handheld through the detachable USB-C host cable, connect a monitor or TV through HDMI, plug in your keyboard, mouse or storage devices through USB, connect Ethernet for wired networking and use the USB-C PD port to power the setup.
This allows compatible handheld gaming devices to function more like a desktop gaming system while remaining easy to disconnect and take on the go.
Key Features
1. 4K@120Hz HDMI 2.1 Output
The CM800 features an HDMI 2.1 output supporting up to 4K@120Hz with a compatible host device, HDMI cable and display.
This provides high-resolution and high-refresh-rate video output for gaming and entertainment.
The HDMI output also supports backward-compatible modes such as 1440p@144Hz and 1080p@360Hz according to UGREEN’s exact-SKU documentation.
Important: 4K@120Hz is the maximum supported HDMI output capability. Actual gaming performance depends on the handheld’s hardware, game, display, cable and graphics settings.
2. VRR, FreeSync & G-Sync Support
The CM800 supports Variable Refresh Rate (VRR), AMD FreeSync and NVIDIA G-Sync compatibility on supported setups.
These technologies can help synchronize the display refresh rate with the source’s frame rate, reducing tearing and improving gaming smoothness.
Actual functionality depends on the handheld, monitor, cable and software.
3. 100W USB-C Power Delivery
The dock accepts up to 100W USB-C PD input and can provide up to 85W to a compatible host device.
This provides additional power for demanding handheld gaming sessions while simultaneously powering the dock and connected accessories.
Important Charging Note
The 100W figure refers to the dock’s PD input, while host-device power delivery can reach up to 85W when supported by the connected device and charger.
For example, different handhelds may negotiate different charging levels depending on their power requirements.
4. Three 5Gbps USB Data Ports
The CM800 provides three high-speed USB data ports:

- 1 × USB-C 3.0
Each is rated for up to 5Gbps data transfer, making the dock suitable for connecting keyboards, mice, controllers, USB drives, SSDs and other peripherals.
The USB-C port is a data port, not a second display output or the PD charging input.
5. Gigabit Ethernet
The built-in Gigabit Ethernet port supports wired networking up to 1000Mbps, providing a more stable network connection than Wi-Fi in many gaming environments.
It is useful for:
- Online gaming
- Game downloads

- Software updates
- File transfers
- Streaming
Actual network performance depends on your router, Ethernet cable, internet service and network conditions.

The stand supports multiple viewing positions and can adjust up to approximately 90°, helping position the handheld comfortably while it is connected to external accessories.
The foldable structure also makes the dock easier to carry when traveling.
7. Detachable 25cm USB-C Host Cable
The CM800 uses a detachable USB-C host cable measuring approximately 25cm.
A detachable cable can make the dock easier to store and provides more flexibility when positioning a handheld on the stand.
8. Compact Aluminum-Alloy Construction
The docking station uses an aluminum-alloy and PC+ABS construction, providing a durable base while keeping the overall design compact.
The foldable construction is designed for both desktop use and portability.
