Connection logic
How it fits into your setup
Plan the complete HDMI route before installation
Place the matrix between the HDMI source devices and the two HDMI displays. Each output chooses one of the four inputs, so the unit can mirror one source to both screens or route a different selected source to each screen. It passes a compatible HDMI signal; it does not create, scale or compose the source picture.
A fully populated installation can require four source-side HDMI cables and two display-side HDMI cables. Audio extraction is optional and needs a separate optical or 3.5mm connection only when an external audio system is part of the plan.
The negotiated format is shaped by every device and cable in the selected route. Mixed displays, long cable runs or an older source can reduce the stable resolution, refresh rate, colour format or audio mode even though the matrix itself is rated for a higher maximum.
Real-world workflows
Use scenarios
Use scenario 1
Keep a media player, game console, computer and set-top box connected while choosing which source appears on two room displays.
Use scenario 2
Send one presentation source to both a confidence monitor and projector, then route another source to either display when needed.
Use scenario 3
Use in a classroom, meeting room or test bench where two displays need flexible access to several HDMI devices.
Use scenario 4
Extract compatible audio to a sound system while the selected HDMI picture continues to a display.
Step-by-step
Setup and usability guidance
Power off the source devices and displays before making the first connection.
Connect up to four HDMI sources to inputs 1–4 and connect display A and display B to the two HDMI outputs.
If external audio is required, connect the appropriate optical or 3.5mm output to compatible audio equipment.
Connect a correctly rated 5V/1A DC supply, then power on displays first and sources afterward.
Use the front controls or remote to assign an input to each output. Select a common resolution if mixed displays do not sync reliably.
If picture or sound is missing, test one short HDMI route at a time, then add the remaining source and display connections.
Match the complete system
Compatible devices and systems
Compatibility check 1
Use with source devices that provide standard HDMI output and televisions, monitors or projectors that accept HDMI input.
Compatibility check 2
For 4K 60Hz, every source, display and HDMI cable in that route must support the required format and bandwidth. Older HDMI equipment can be used at a mutually supported lower resolution.
Compatibility check 3
Optical and 3.5mm audio operation depends on the source audio format and the connected amplifier, speaker or headset input.
What this product does
- Selects and routes one of four HDMI inputs to each of two HDMI outputs.
- Can mirror one source to both displays or show two selected sources, one per display.
- Passes compatible digital video and audio and provides audio-extraction connections.
- Keeps sources connected while switching from the panel or remote.
What this product does not do
- It does not combine several sources into a quad-view or picture-in-picture image.
- It does not create extra computer desktops; the graphics device still controls mirror or extended-display behaviour.
- It is not a KVM and does not switch USB keyboards, mice or storage.
- It does not convert DisplayPort, USB-C, VGA or wireless video to HDMI.
- It cannot add 4K, HDR, HDCP or surround-audio support to equipment that lacks those capabilities.
Important limitations
Check before buying
Use this checklist to confirm the exact model suits the intended job.
- Confirm that you need a matrix with independent output selection, rather than a simple splitter or a multi-viewer.
- Count the HDMI cables required and verify that each one is rated for the intended resolution and distance.
- Check that both destination displays accept HDMI and share a usable resolution and audio format with each selected source.
- Allow access to the front controls or a clear line of sight for the infrared remote receiver.
- Plan a ventilated position near the specified 5V/1A power connection; this is a powered device.
What to do
- Use certified HDMI cables rated for the intended resolution and keep high-bandwidth runs as short as practical.
- Set source resolution and audio format to values accepted by the destination display or audio system.
- Allow ventilation around the powered unit and keep the infrared receiver visible when using the remote.
- Label inputs and outputs in permanent installations so routing changes are easy to reproduce.
What not to do
- Do not expect two unrelated images on one screen; that requires a multi-viewer.
- Do not hot-plug repeatedly during unstable playback if a controlled power cycle can be used instead.
- Do not force optical, HDMI or DC connectors, and do not use a supply with an unverified voltage or polarity.
- Do not cover the unit, expose it to moisture or route cables where connector weight pulls on the sockets.
Safe and realistic operation
Warnings and limitations
Warning 1
Mixed displays can force a lower common resolution, colour format or audio capability. A 4K display and a 1080p display may not both receive their individual optimum format.
Warning 2
4K 60Hz and HDR require compatible sources, displays and cables; the matrix cannot repair an inadequate cable run.
Warning 3
ARC availability depends on the connected output path and equipment configuration. Confirm the intended ARC and audio route during setup before depending on it.
Warning 4
The 3.5mm connection is analogue stereo; do not assume it carries multichannel formats intended for optical or HDMI.
Warning 5
Always use the specified powered connection. Unpowered or incorrectly powered operation can cause loss of picture, repeated handshakes or instability.
Practical first checks
Troubleshooting guide
| If you notice | Check this first |
|---|---|
| No picture on either display | Confirm the 5V/1A supply, select the intended input for each output, and test one short source-to-display route before rebuilding the full installation. |
| One display works and the other does not | Test the second display alone, then set the source to a resolution and refresh rate accepted by both displays. Replace or shorten the failing HDMI cable if necessary. |
| 4K 60Hz is unstable | Verify the source, destination and both cables in that route support the required bandwidth. Temporarily choose 4K 30Hz or 1080p to isolate a bandwidth problem. |
| Picture appears but external audio is silent | Choose an audio format supported by the connected optical or analogue destination. A 3.5mm output should be treated as analogue stereo. |
| Remote switching is unreliable | Keep the infrared receiver visible, check the remote battery and use the front-panel controls to confirm that routing works independently of the remote. |

Helpful answers
Product-specific FAQ
Can the two outputs show different sources?
Yes. A matrix switch is designed so output A and output B can select inputs independently. Both outputs may also select the same input for mirroring.
Can it show four sources together on one screen?
No. It routes sources; it does not compose a quad-view, picture-in-picture or video-wall layout.
Will every setup run at 4K 60Hz?
Only when the selected source, both relevant HDMI cables and the destination display support that format. Otherwise choose a mutually supported lower resolution.
Does it create a dual-monitor extended desktop?
No. The matrix routes HDMI signals. Extended or mirrored desktop modes must be generated by the computer or graphics hardware before the signals reach the matrix.
Can I use optical and 3.5mm audio at the same time?
The product provides both connection types, but usable output depends on the selected source format and receiving audio equipment. Choose stereo PCM when an analogue 3.5mm destination cannot decode multichannel audio.
Why does one display lose picture when both are connected?
The displays may report different capabilities. Test each route separately, set a common resolution and refresh rate, and replace any cable that cannot carry the selected bandwidth.
Is the remote required?
No for basic routing because front-panel controls are provided. The remote is useful when the matrix is installed out of easy reach.
Are HDMI cables included?
HDMI cables are not confirmed as included. Plan one cable for every connected source and display.
Is this the same as a basic HDMI splitter?
No. A splitter normally duplicates one source to several displays. This 4×2 matrix lets each of two outputs select from four connected inputs, while still allowing both outputs to choose the same source.
Does the matrix upscale a 1080p source to 4K?
No upscaling is promised. It routes the source signal in a format accepted by the selected display path; source and display settings determine the actual output format.
Can it switch a keyboard, mouse or USB storage with the video?
No. Model 70435 switches HDMI video and compatible audio only. A separate KVM or USB switch is required for USB peripherals.

Research and source note
Research basis: the exact live Shopify product and variant record, the product-owned Shopify CDN media attached to that record, and the exact-SKU UGREEN references already cited in this draft. Regional claims were not blended when they conflicted; the conservative verified value is used instead.
Model-specific decision: Exact SKU 70435 is a powered 4-input/2-output HDMI matrix. The exact remote artwork includes an ARC button, but a detailed ARC route and procedure are not promised here because the verified source set does not publish a complete ARC workflow or full manual. Follow the supplied manual for that control.
- No external or unrelated media used.
- No unverified package accessory list or unsupported ARC procedure added.
