Review: A slow journey to a bitter end - Not happy at all. It worked fine for a couple of weeks but then displays started not coming on and then they would randomly blink off and on. I went to pull the cord out to try in a different USB-C port and the whole tip pulled out of the housing. I tried using just the USB three and but none of my displays would come up. I noticed also that the unit was very hot to the touch. Review: Awesome - This is awesome. Please go for it and it's working on Mac & Windows.

I went to pull the cord out to try in a different USB-C port and the whole tip pulled out of the housing. I tried using just the USB three and but none of my displays would come up.

Mirror - Yes Extend to all the 4 external monitors - Yes. Hence cumulatively, we're getting 5 different displays. ### ⭐⭐⭐⭐⭐ Pure magic *by C***E on 5 July 2025* I love my Mac and buy a new one every 5 years or so leaving me with a working "legacy" model cause Mac's die tough. The one in my picture is a 2019 MacBook Air in a 13" model. So the native capabilities of this Mac for multiple extended displays was natively limited to one. Not sure if the limitations of the video card or it only has (2) thunderbolt ports and one is the charge port. Anyhow, I have (3) monitors from my work setup having recently retired and wanted to put them to use as they are fairly new 32" curved monitors. Very simple to setup and to my surprise, worked like magic even on the older limited video capabilities of my old Mac. I see some who left mixed reviews and I was hesitant but did not see much in anything even close with (4) extended screen plus use of my laptops screen (so capable of (5) total screens!). Especially not at this price. I am completely thrilled. There is a little flicker or buffer for a couple seconds only when I first wake up my laptop while it allocates the signals to generate the 3 screens I'm using but it's brief and then it does not do it again. Works fantastic for me. Super fast shipping. Amazon has a great policy with vendors for return and I have always been happy with Amazon, so I decided to purchase and am completely satisfied, thrilled matter of fact. Great product, great solution. I was not payed or otherwise received anything for this review but when I find a great product or get great service, I take the time to say so. Super fast shipping too ## Frequently Bought Together - OREI SplitExtend HDMI Splitter Extended Display for Quad Monitor - Multi-Monitor Display 5 Separate Screens - USB-C Adapter to HDMI 2.0, 4K@30Hz Outputs - Windows and Mac Compatible - 10K 8K HDMI 2.1 Cable 2-Pack 6.6FT, Highwings Certified 48Gbps Ultra High Speed Slim HDMI Cord,Support 4K@120Hz 8K@60Hz, HDCP 2.2&2.3, Dynamic HDR,eARC,DTS:X, Compatible with Roku TV/HDTV/PS5/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.us/products/743336197-splitextend-hdmi-splitter-extended-display-for-quad-monitor-4k-30hz](https://www.desertcart.us/products/743336197-splitextend-hdmi-splitter-extended-display-for-quad-monitor-4k-30hz) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-09*
