The best HDMI switchers for 4K 120Hz are HDMI 2.1 models that explicitly list 4K at 120Hz support. The OREI 8K 3-port and 2-port switches and UGREEN 3-port model fit that need based on their listed specifications. The UGREEN 5-port and Kinivo 5-port models are better suited to setups where adding inputs matters more than 4K 120Hz output; their provided specifications do not confirm that resolution and refresh rate.
| Product | Best For | Listed 4K 120Hz Support |
|---|---|---|
| OREI 8K 3-Port | Three sources and gaming features | Yes |
| UGREEN 8K 3-Port | Three sources and remote switching | Yes |
| OREI 8K 2-Port | Two sources and 48Gbps bandwidth | Yes |
| UGREEN 8K 5-Port | Five sources; lower listed refresh rates | Not specified |
| Kinivo 4K 5-Port | Five sources at up to 4K 60Hz | No |
OREI 8K 3-Port HDMI 2.1 Switch
Best for: Gamers and home-theater users connecting three HDMI sources to one display. This OREI switch lists 4K at 120Hz, 8K at 60Hz, and 48Gbps bandwidth, along with HDMI 2.1 and HDCP 2.3 compliance.
It also supports VRR, ALLM, and QFT, features intended to support responsive gameplay, plus HDR10+, Dolby Vision, CEC, and 3D. Listed audio formats include Dolby TrueHD and DTS-HD Master Audio. Choose it if gaming features and broad audio-format support are priorities.
Limitation: The product information does not specify included cables or a remote, so check the listing for what comes in the box.
UGREEN 8K 3-Port HDMI Switch
Best for: People who want to connect three sources and switch between them with a remote. The specifications list 4K at 120Hz, 144Hz, and 240Hz, as well as 8K at 60Hz, 40Gbps bandwidth, and HDMI 2.1.
VRR, G-Sync, and FreeSync are listed for compatible gaming setups. The switch also supports Dynamic HDR 10+, Dolby Atmos, and HDCP 2.3. A 5V/1A power cable is included, but the product details say the power adapter and HDMI cables are not included.
Limitation: This is a switch, not a splitter; it does not display one source on multiple monitors at once. The listed cable-length guidance for high refresh rates is within 3 meters for both input and output cables.
OREI 8K 2-Port HDMI 2.1 Switch
Best for: A two-source setup that needs 4K at 120Hz without extra input capacity. The switch lists 8K at 60Hz, 4K at 120Hz, 48Gbps bandwidth, HDMI 2.1, and HDCP 2.3/2.2/1.4 support.
It offers both manual and automatic switching. The automatic mode activates when the active source is completely powered off; manual selection remains available. Gaming features include VRR, ALLM, and QFT. Listed video and audio support includes HDR10+, Dolby Vision, Dolby Atmos, and DTS 7.1.
Limitation: It accepts only two sources. The product details list HDMI cable lengths up to 10 feet and recommend OREI fiber-optic HDMI cables for longer runs.
UGREEN 8K 5-Port HDMI Switch
Best for: Users who need five connected sources, such as consoles, a streaming device, and a laptop, routed to one display. It includes a remote and lists 8K at 60Hz, 40Gbps bandwidth, VRR, HDR10+, Dolby Atmos, and HDCP 2.3.
Its listed resolution details include 4K at 60Hz and 1080p at 240Hz, but they do not confirm 4K at 120Hz. Choose it for input expansion only after checking that its supported modes meet your display and device requirements.
Limitation: This is not the clearest match for a 4K 120Hz requirement because that mode is not listed. The manufacturer gives cable-length guidance of up to 1 meter at input and 2 meters at output for high refresh rates.
Kinivo 550BN 5-Port HDMI Switch
Best for: A five-device setup where 4K at 60Hz is sufficient. Kinivo lists 4K 60Hz, 18Gbps bandwidth, HDR10, Dolby Vision, Dolby Atmos, HDCP 2.2, and an IR remote. It also lists VRR and ALLM.
This model can consolidate multiple HDMI sources into one display input, and the product details name consoles, streaming devices, and cable boxes as examples. It is a better fit for standard 4K viewing than for high-refresh-rate gaming at 4K.
Limitation: The supplied specifications do not list 4K at 120Hz; they mention 2K at 120Hz instead. Do not choose it for a required 4K 120Hz signal without confirming support with the seller.
Buying Guide: How To Choose An HDMI Switcher
Does the switch explicitly support 4K at 120Hz?
Check the exact resolution-and-refresh-rate combination in the product specifications. “8K,” “HDMI 2.1,” or “high bandwidth” alone does not establish that 4K at 120Hz is supported. Among these options, the OREI 2-port and 3-port models and UGREEN 3-port model explicitly list 4K 120Hz.
How many HDMI sources need to stay connected?
Count the devices you use regularly. A two-port switch is suited to a simple setup; a three-port switch accommodates an additional source. Five-port options offer more inputs, but the listed UGREEN and Kinivo models do not confirm 4K 120Hz. Match input count to your actual display needs.
What gaming features and accessories matter?
VRR, ALLM, and QFT appear in the specifications of some models and may matter when connecting compatible gaming equipment. Also check whether a remote, power cable, power adapter, or HDMI cables are included. Cable length can affect whether a high-resolution, high-refresh-rate signal works as intended.

The OREI 8K 2-port HDMI 2.1 switch lists 4K at 120Hz and accepts two HDMI sources.
Is HDMI 2.1 enough to guarantee 4K 120Hz?
No. Confirm that the switch explicitly lists 4K at 120Hz, and check the source, display, and cable specifications too.
Which option offers the most inputs?
The UGREEN 8K 5-port and Kinivo 550BN both accept five sources. Their provided specifications do not establish 4K 120Hz support.
