Had a little bit of a rough time with the driver installation, but just followed the instructions included. My driver had to be installed manually. I work in tech support so it was pretty easy for me to get it working. Great for laptops with SS USB-C ports to use multiple monitors. I have 3 connected with no issues.

I bought this to use 4 screens with one machine to be more productive than with 2 screens. Also, I figured It would come in handy with learning to trade. It works as needed, even with one of my screens being a small television. It increased my productivity as I expected and because I use several remote computers I can now use more of them at one time. Excellent purchase.Side note. I tried to use it with a KVM so that I can have 4 screens between two machines but it gets glitchy trying to go between the machines as each one has to re-due the display settings each time. Sometimes one of the screens would not come on for a long time and sometimes it wouldn't come on at all. Connecting to the other machines virtually works better but now I can only use one of the 4 screens per virtual computer. But that still works out for me.

. Great addition to my edit display which was better than a vgr card with connectors but I purchased which doesn't work in the same fashion. But this definitely works save the space and time and I don't have to worry about inserting cords or anything this is strictly directly to the point. Pretty much feels like they'll be getting rid of or phasing out graphics cards with this particular device. Or at least that's the field that I get which is probably already in the works in the first place however but it's great for extra displays I'll be purchasing some more.

I work from home and I use this to attach my four monitors to my laptop. Works well. It does get hot, but I found out that this is normal. I've been using this since November 2023. No issues so far. If it stopped working, I would definitely buy again.

This thing was amazing for the first 45 days.I ran 3 1080p monitors off it with no issues.It would get hot but I figured it was made to run that hot. Not so.Now I’m getting screen glitching and freezing.Don’t get it without the extended warranty you will need it!!!

I bought a LENOVO IDEAPAD 3($200) April 2023, a brand new version (Widows 11).I tried to add multiple monitor for months and tried any docking system known in the market.Nothing worked until I purchased this 4-Hdmi with USB-3 adapter. After speaking with Starlink customer service(waited 1Hr-2min) I was still skeptical this product may not work with Lenovo. After I connect HDMI connection only 3 monitor appear. Once I download the driver based on the product ID, now I have 5-monitor running same with all individual identity. THIS PRODUCT IS A LIFE SAVER, PLUG AND PLAY did the job. Customer service was beyond my expectation. You need to wait but will never be disappointed.As long as I have Windows it will have no issue they assured. They did not play any game but genuine help. No display of know it all attitude. YOU NEED MULTIPLE MONITOR - SPEND FEW EXTRA BUCKS IT IS WORTH IT 100%.

Works great. Usb3, running 4x 1080p HDMI displays without any issues at all. Plug and play, seamless install. Used the native windows 11 display settings to move windows around. All good. Recommended

After getting played many times with other “splitters†this one actually worked so that I can use up to four other monitors individually and not just mirrored!! Great buy

Por mi afición tenÃa que tener varias pantallas a la vez y cumple perfectamente su cometido, utilizo cuatro pantallas simultáneamente y en cada una con un programa distinto y genial. Con un simple puerto de USB puedo usar hasta cuatro pantallas, Windows lo reconoce perfectamente.

Sehr gut gefallen hat mir, angeschlossen und Zack hat gleich funktioniert, ohne langwierige Installation. Verwendung: Betreiben von mehreren Monitore für eine Stellwerk-Simulation.
