BENFEI USB 3.0 to HDMI Adapter, 1080P HDMI to USB Converter for PC Laptop Projector Monitor HDTV,Aluminium Shell( Advanced chip solution: FL2000+IT66121)

This device expands a laptop or a pc. Most new laptops have a built in HDMI port which is fine but what if you want a second remote screen to give you three working screens?This device does just that.It works with windows 11 and backward compatible with 10, 8, 7.Mouse or document drag is seamless between screens and for those who need that functionality, this works exactly as it should.It does get warm, not enough to toast bread but it does get warm so expect that.The devices comes with an in built driver which your machine will recognise but also has a disk so you can email your IT with drivers. The disk is, or at least mine was, clean from virus etc..Highly recommended.

First of all the important bit.. yes it works when I connected USB3.0<>HDMi and also USB3.0<>HDMItoDVIadapter<>DVI. The picture resolution is full HD and perfect quality. I have actually got 3x monitors so 2 of them are on the card (Dsub, DVI) and this third monitor is on USB3.0. Everything was working fine and I was thinking about leaving a 5 star review because there are very few products of this class which actually works... But... here comes the but... I have connected it to my Desktop/Server system where I do lot of work including work on virtual machines so I do not turn off my PC for weeks even months because I don't want to waste time spinning up all VMs and opening all docs and browser pages etc. I normally send it to sleep before going to bed or the PC automatically goes to sleep/hibernate after 2 hours or so... after the installation of this adapter I went away for few hours and when I came back all my monitors were blank and PC was on. No matter what I tried the PC didn't come to life until I did a hard reboot and it all came back with a clean slate. So all work was gone! I then tried to manually hibernate it from start>shutdown>sleep and it went well, all monitors went to sleep but within 2 mins PC restarted! I tried different combination of cables, even shutdown power saving for USB port but it will restart every time if I put it in sleep mode (manually) or it will just hang if system goes to sleep after set duration. As soon as I removed the box the sleep functionality started working as normal. So, for some very odd reason, this box does not work for SLEEP/HIBERNATE mode. If you are a person like myself who does not want to turn off his PC then just consider above issue otherwise the device is fine.= = =I have had a detailed discussion about this issue with Benfei customer services and they have been very helpful in determining the issue and sending me another product to test. The new item they sent did work well with no issues at all (on Windows 10) so I think the previous item may have some issues which was causing the problem. Based on their response and excellent customer services I am elevating the rating from 3 to 5.

Works fine once the driver is installed. Shame it's not picked up by windows and didn't need a random proprietary driver to work.

Okay so my review will be a little long. But will be well worth the read if you wish to know about the amazing service I received from the company, and about the product itself.So for a little backstory, I wanted to add a second monitor to my laptop for work but only had one HDMI (that extends the display, not duplicates it). I ended up getting this product and it worked perfectly the first time. However when I unplugged it to fix up some cables it no longer worked. My laptop could recognise that a device was plugged in but no information was going through.I emailed Benfei support explaining what had happened, what troubleshooting I did, and some screenshots. I received a email back from them explaining that the adapter was most likely defective. They went on to say that they would send a replacement free of charge, I didn't even have to go through the trouble of sending back the defective one!They asked for my order details and provided an estimated time of delivery. It ended up coming a day earlier and worked perfectly.Overall while at the beginning it was a little annoying. The amazing customer service made up for it 10 times over. I would heavily recommend this device and the company as a whole. Its honestly refreshing to see a company go so much out of their way to fix the issue.

Update: Still no contact from Benfei but noticed other reviewers talking about a driver download. My package didn't come with a disk or instructions, so I hadn't realised. I went on the Benfei website and it turns out the driver is not compatable with Chromebooks. With Chromebooks increasing in popularity, they really ought to make that explicitly clear in the description.Original review: I tried this adapter on three different laptops (2 chromebooks and 1 Windows laptop) and none of them would recognise the external monitor that it was connecting to. I then bought a different product which worked immediately, so this adapter is clearly faulty. Sadly, I bought it in advance of a birthday and by the time I tested it, I was 1 day past the 30 day return window - my fault for being too organised. Amazon will not help with a refund and the Benfei weblink which Amazon points me to doesn't work. I've left feedback with the seller so I'll see if they respond and accept a return - if they do, I'll update this review.

I've seen this to work and to not work on different motherboards. Not sure if it's a MOBO issue or a USB issue or this device; I've never really fully investigated it. I'm hanging on to it though, as it was cheap and it might get me out of a spot some day...

Plugged it in, installed the driver as per the instructions. Restarted the PC. Plugged the hdmi into the adapter. Screen showed up immediately. Now I have 2 external and the laptop display working fine. The screens I have are ultrawides, the laptop had only one hdmi and tried a hub which didn't work. Definitely would recommend.

Exactly what I needed!

Works fine. Have to install driver before using but it does it automatically.

Ha sido una buena experiencia, compré uno a la miad de precio y no funcionó bien, este ha funcionado muy bien!! Recomendable!!

presa perfettamente funzionante, consigliata

Works very well.Make sure you install the drivers.
