1x2 HDMI Splitter 4K 60Hz

The PORTTA 122HD4K-N2SP12Y duplicates one HDMI source to two displays simultaneously. It supports Ultra HD resolution up to 4K at 60 Hz with YUV 4:4:4 colour sampling and 18 Gbps total bandwidth. HDCP 2.2 and HDCP 1.4 are both supported alongside High Dynamic Range video. The aluminium housing aids heat dissipation during continuous operation.

EDID modes and downscaler

Three EDID modes — auto, copy and downscaler — let you match the source output to the connected sinks. Auto mode reads the lowest common resolution and audio format from both outputs. Copy mode mirrors output one and downscales resolution only if the second display cannot match it. The dedicated downscaler mode converts a 4K input to 1080p for one screen while passing 4K to the other. Builders who need to split a signal to more than two screens should look at a different device.

4K 60 Hz YUV 4:4:4 bandwidth

The single spec that decides fit is the 18 Gbps aggregate bandwidth at 4K 60 Hz YUV 4:4:4. If your source and displays require higher throughput — for example 4K at higher refresh rates or greater colour depth — this splitter cannot pass the full signal unchanged. For standard 4K 60 Hz HDR sources and two compatible sinks it delivers the complete uncompressed picture and audio.

Questions about this item

What HDMI source and cables do I need to connect to the single HDMI input?

Connect any HDMI source such as a media player, console or PC to the one HDMI input using a standard HDMI cable; the splitter then feeds two HDMI outputs to your displays

Will my older 1080p monitor work alongside a 4K screen on the two HDMI outputs?

Yes, the downscaler EDID mode lets the splitter send 4K@60Hz to the 4K display while simultaneously downscaling to 1080p for the older monitor

How can I verify the splitter is passing 4K 60 Hz and HDR correctly after setup?

Play 4K HDR test content and confirm both displays show a stable picture at 60 Hz; the front-panel LED indicates active signal and the selected EDID mode
