Source and Display Settings： Confirm that both your HDMI source device (e.g., laptop) and HDMI display (e.g., monitor) are set to support your desired resolution and refresh rate. No ARC/eARC Support： This device does not support Audio Return Channel (ARC) or enhanced Audio Return Channel (eARC). Downscaler Limitations： The downscaler only supports 4K to 1080p conversion and does not change the refresh rate (e.g., 4K60Hz becomes 1080p60Hz, and 4K120Hz becomes 1080p120Hz). For PS5:Go to Settings → Screen and Video → Resolution and set it to Automatic.Enable VRR, 120Hz Output, and ALLM in the settings menu.Under Saved Data and Game/App Settings → Game Presets, choose either Performance Mode or Resolution Mode based on your preference. For Xbox: Navigate to Profile & system → Settings → General → TV & display options.Set the resolution to 4K UHD and the refresh rate to 120Hz.Enable "Allow variable refresh rate" under Video modes. F or NVIDIA (PC): Open the NVIDIA Control Panel and go to Resolution settings.Scroll to PC resolutions, select 4K, and then choose 120Hz as the refresh rate. Troubleshooting Tips： If audio/video issues occur:Check power supply (5V 1A+).Verify HDMI 2.1 cable less than 3M. EDID switches match your audio format. Review: Works with Switch 2 and old 5.1 audio system - I’ve only just set this up, so if issues occur down the line, I’ll update this review. I bought this for the specific purpose of sending Nintendo Switch 2 video signal to a TV supporting its features (120hz, HDR, etc) and its audio to an old Sony Blu-Ray 5.1 surround sound system. This is because the Switch 2 outputs an uncompressed 5.1 feed that my relatively modern TV cannot pass through to the old receiver in anything but stereo. The good news is that this item serves this particular need very well. The Switch 2 goes into the HDMI “in” port, the video is then passed through and goes out the HDMI OUT 1 port (using an HDMI 2.1 cable). The audio goes out via HDMI OUT 2, and I’m using an HDMI 1.4 cable for that, as I don’t need to carry 4K 120hz video signal for that, as it’s just audio. That plugs into one of the audio receiver’s HDMI ports. If you’re pursuing a similar setup, I recommend the following settings. I had the EDID dip switches in the OFF-OFF-ON position to tell the Switch it was plugged into a 5.1-capable device. Importantly, I had to turn ON the 4K to 1080p downscaling switch on the HDMI OUT 2 port going to the audio receiver, as I wasn’t getting sound otherwise. So, 4K downscaling is OFF to the TV, but on to the receiver. These settings worked well for me. When using the Switch, my TV’s HDMI input is set for the cable running from HDMI OUT 1 of this device, and my audio receiver Blu-Ray box is set to one of its two HDMI IN ports. I now have full functionality of the TV and 5.1 audio from the Switch. Should all of this be necessary? Of course not. Should the Switch 2 offer some kind of 5.1 compressed audio? Absolutely. But, if you’re annoyed by having to use stereo on your 5.1-capable Switch, then this device offers a pretty elegant solution. Let’s see if it stands the test of time. Yes, it runs a bit warm, but I’m not sure I’m having quite the experience others have mentioned. Review: If only this worked - This offered everything I needed in a splitter, plenty of edid options and downscaling. It let arc passthrough and cec worked, even stripped hdcp. The serious problem I had though is I had two units and I had to return both because they were faulty. The picture dropped out and sound went wonky. For the amount they charge for these the quality is poor. I'll have to look elsewhere. ## Features - 4K 120Hz HDMI 2.1 Splitter 1 in 2 out: Aluminum HDMI Splitter for Dual Monitor Duplicate/Mirror 4K 120hz & 1080P 120Hz work in Sync for Xbox, PS5 4K 120Hz, Sky q, IPS gaming monitor,Up to 8K@60Hz,4K@120Hz, D-olby vision, HDR and HDCP2.3, Deep Color, 3D, Lip Sync,EDID management,Down scaler function. - True 8K Ultra HD VRR ALLM Video & Audio Format：Video Format:HDMI 2.1 Splitter supports multiple resolution up to 8K@60Hz 4K@120Hz 5120x1440@120Hz 1080P@240Hz 4:4:4 8bit VRR ALLM HDR10 HDCP2.3 D-olby vision, 3D effect.

It let arc passthrough and cec worked, even stripped hdcp. The serious problem I had though is I had two units and I had to return both because they were faulty.

My PlayStation connected to my Sony tv uses VRR and ALLM with 120htz my Philips Hue is just out of date with no such pass through features and i dont want to spend £299 for a new sync box. I had read the reviews and someone said they had used this for their sync box so thought i would give this a try, even though the more expensive version of this more people have used. After lots of messing around with the dip switches, i have finally found the best solution and it looks like it’s all working and my hue sync box now works with my lightstrip again. For anyone who is looking for a good option to use with PlayStation and hue sync box 2.0 this is it. All you need to do(after lots of messing around) is turn the 2nd dip switch down on the two on the front, this should be labelled HDMI2 1080p, this still gives then 4K and everything else to my Sony tv and the sync works fine. The only thing i need to do now is start the sync on my app which takes 30 seconds, its a very small inconvenience but has saved me £250 on a new box ## Frequently Bought Together - 4K 120Hz HDMI 2.1 Splitter 8K 60Hz 1 in2 out VRR ALLM HDCP2.3 HDR10 8KUHD D-olby Vision Atmos Scaler 4K EDID 1080P Dual Monitors HDMI 2.1 Splitter 1X2 for PS5 SkyQ Xbox NVIDIA AMD - Southlight HDMI 2.1 Cable 3M,8K@60Hz 4K@120Hz Ultra HD Cable High-Speed Lead 48Gbps,7680x4320,Supports eARC HDR10 HDCP 2.2 & 2.3 DTS: X 3D CEC Compatible with all HDMI devices PC/TV/HDTV/Blu-ray --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/535999208-rofavezco-4k-120hz-hdmi-2-1-splitter-8k-60hz-1](https://www.desertcart.sn/products/535999208-rofavezco-4k-120hz-hdmi-2-1-splitter-8k-60hz-1) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-11-12*
