UGREEN 70607 CM311 Bi-Directional HDMI Switch – Flexible HDMI Connectivity
The UGREEN 70607 CM311 HDMI Bi-Directional Switch is a compact HDMI 2.0 switching device designed to simplify connections between multiple HDMI sources and displays.
Its bidirectional design supports two practical connection configurations: connecting two HDMI source devices to one display or connecting one HDMI source to two displays with manual selection.
This makes it useful for home entertainment systems, gaming setups, office workstations and multimedia installations where HDMI connections need to be changed regularly.
Instead of repeatedly disconnecting and reconnecting HDMI cables, users can select the desired connection using the integrated button.
The switch supports up to 4K Ultra HD at 60Hz, HDMI 2.0 bandwidth of 18Gbps, compatible HDR formats and supported digital audio technologies.
An HDMI cable is also included with the product.
Two Operating Modes in One HDMI Switch
The UGREEN CM311 provides bidirectional switching, allowing it to operate in either of two configurations.
Mode 1: Two HDMI Inputs to One HDMI Output (2 In 1 Out)
Connect two HDMI source devices to a single HDMI display.
For example:
- PS5 and Xbox connected to one television
- Desktop PC and laptop connected to one monitor
- TV box and Blu-ray player connected to one TV
- Gaming console and media player connected to one projector
Press the selection button to choose which HDMI source appears on the connected display.
Only one source is active at a time.
Mode 2: One HDMI Input to Two HDMI Outputs (1 In 2 Out)
Connect one HDMI source device to two separate HDMI displays.
For example:
- One desktop computer connected to two monitors
- One laptop connected to a monitor and projector
- One gaming console connected to two televisions
- One media player connected to two HDMI displays
The button selects which display receives the HDMI signal.
Important: The UGREEN CM311 cannot send video to both displays simultaneously. It is a selectable HDMI switch, not a simultaneous-output HDMI splitter.
It also cannot extend a computer desktop across two monitors.
4K Ultra HD Resolution at 60Hz
The UGREEN 70607 supports video resolutions up to 4K@60Hz with compatible HDMI equipment.
Supported video modes listed in the supplied product information include:
- 4K Ultra HD at 60Hz
- 4K Ultra HD at 30Hz
- 2K at 120Hz
- 1080p at supported refresh rates
- 3D video with compatible equipment
The switch is designed for connecting compatible high-resolution televisions, gaming displays, computer monitors and projectors.
To achieve 4K@60Hz, the HDMI source, display, HDMI cables and relevant settings must all support the required video format.
The manufacturer’s guidance recommends standard HDMI 2.0 cables and short cable connections for reliable 4K@60Hz transmission.
HDMI 2.0 with 18Gbps Transmission Bandwidth
The CM311 supports HDMI 2.0 transmission bandwidth of up to 18Gbps.
This provides the bandwidth required for supported high-resolution video and compatible digital audio signals.
Its integrated processing chip manages HDMI signal switching between the selected connections.
Actual transmission performance depends on the quality and length of the connected HDMI cables, as well as the capabilities of the source and display.
The switch does not improve the resolution or refresh rate of an unsupported source device.
HDR, Dolby Vision and HDCP 2.2 Compatibility
The UGREEN CM311 supports several video technologies used by compatible entertainment equipment.
These include:
- HDR video
- Dolby Vision
- HDCP 2.2
- 3D video
These features are useful when connecting supported streaming devices, media players, gaming consoles and televisions.
HDR and Dolby Vision functionality requires compatible content, source hardware and display equipment.
HDCP 2.2 compatibility supports protected content workflows when all devices in the connection meet the necessary requirements.
Dolby Atmos and Digital Surround Sound Support
The UGREEN 70607 is designed to pass supported digital audio signals through the HDMI connection.
The supplied product specifications identify compatibility with:
- Dolby Atmos
- Dolby TrueHD
- Dolby AC-3
- DTS-HD
- DTS
- LPCM 7.1
- DSD
This makes the switch suitable for compatible home entertainment systems where digital video and audio need to travel through the selected HDMI connection.
The actual audio format available depends on the source device, connected display or audio equipment, and the content being played.
The switch does not independently decode or generate surround sound.
One-Button HDMI Switching
The CM311 features a physical selection button for changing the active HDMI connection.
Press the button to switch between the two selectable HDMI channels.
This provides a straightforward alternative to repeatedly unplugging HDMI cables when changing between devices.
The manufacturer notes that switching can require approximately 3–7 seconds while the connected devices establish the new HDMI signal.
This delay is normal and should not be confused with continuous video transmission latency.
Blue LED Channel Indicators
Two LED indicators show which HDMI channel is selected.
The indicators help identify the active connection, particularly when multiple devices are connected to the switch.
The manufacturer also states that the switch does not have a memory function.
After initialization, HDMI channel 1 is the default selection.
No External Power Adapter Required
The UGREEN CM311 is powered through the connected HDMI equipment.
A separate power adapter is not required for its normal operation.
This helps reduce cable clutter around televisions, gaming consoles, computer desks and entertainment cabinets.
The switch must be connected to compatible powered HDMI equipment to operate correctly.
Compact ABS Housing
The CM311 uses a black ABS housing designed for everyday desktop and entertainment use.
Its compact dimensions allow it to fit near a television, monitor, gaming console or computer workstation without occupying substantial space.
The ABS enclosure houses the HDMI switching electronics, selection button and LED indicators.
The product weighs approximately 110 grams according to the supplied product information.

For example, a user can connect a PS5 and Xbox to the same display and select the desired console using the button.
It also allows one console to be connected to two displays, with one selected at a time.
The switch supports up to 4K@60Hz, but 4K@120Hz gaming and HDMI 2.1-specific features are not specified for this model.
Users requiring 4K@120Hz should select an HDMI switch explicitly rated for that capability.
Convenient for Office and Computer Workstations
The CM311 is also useful for computer setups involving shared displays.
It can connect a desktop computer and laptop to one monitor, reducing the need to disconnect HDMI cables when changing devices.
Alternatively, it can connect one HDMI source to two displays and allow the user to select the active screen.
The switch is not a KVM switch and does not switch USB keyboards, mice or other USB peripherals.
