4K HDMI Splitter 1 in 2 Out Mirror Display Not Expand, Dual HDMI Splitter Hub to Dual Monitors Multi-Scree Displays Audio Synchronization, Compatible for MacBook Laptop Desktop PC Graphics Card TV

The Splitter arrived on time in a resealable plastic bag along with a "Type A > Micro " USB cable and a approximately 6 inch HDMI Cable. I tested the Splitter using a 20 watt USB Adapter and attached it to a 2020 Asus Laptop running Windows10 Home and using the Karafun Karaoke app with the Splitter driving a 720p Panasonic TV and an HP 1080p Monitor. I used it in the "EXPAND DESKTOP" display setting on the laptop. The splitter performed perfectly and appeared to pass the signal independently to each display device. There was no visible interference caused by different resolutions on the splitter output. this appears to be a great unit and well worth the money. I am considering purchasing one or two more for upcoming projects

I’ve been using this 4K HDMI Splitter 1 in 2 Out for a while now, and it performs exactly as advertised. The setup was quick—just plug in the power and HDMI cables, and both screens displayed perfectly with no need for extra software. The picture quality is clear and consistent at 4K resolution, and there’s no noticeable lag or drop in audio quality. It’s important to note that this splitter mirrors the same display on both monitors, not extends the screen, but it’s great for presentations, dual TV setups, or mirroring content between a laptop and an external display. The build feels sturdy, and it stays cool even after long hours of use.

It works with no issues

Works fine most of the time. Sometimes it acts a bit wonky with a couple of monitors I use in a professional Trivia setup. I can always quickly disconnect and reconnect it to recover. I haven't spent the time to figure out if it is this unit or my monitors that are the actual issue. It gets added and removed from the setup daily as we move from place to place. For the cost, it is still a good deal and I wouldn't hesitate to buy it especially if your setup is a bit more static than mine.

Not working at all.

This splitter does exactly what it says it will do, just not in the way I actually wanted. No fault of the hardware. I'll still find a use for it working as it does

The splitter worked well but the plastic housing is not sturdy. The bottom of the housing easily popped off.

The 4K HDMI Splitter 1 in 2 Out Mirror Display is a fantastic solution for anyone looking to duplicate their screen effortlessly. Setup was incredibly simple—just plug and play with no additional configuration needed. The picture quality remains crystal clear, with no lag or degradation, even when splitting to two displays. I’ve used it for gaming and streaming, and both screens maintained flawless 4K resolution. The build quality feels solid, and it runs smoothly without overheating. It’s a perfect tool for presentations, dual-monitor setups, or sharing content across multiple screens. Highly recommend for anyone needing a reliable HDMI splitter!
