USB to VGA Adapter

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.

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.

It works - but requires a driver. There is a mini-cd, but when plugged in, the driver shows as another hard disk in Windows (not sure about Mac, I guess it won't work on Linux?) If you are not an admin in Windows, don't bother getting this. Make sure it's plugged into a USB3 port. My laptop has two different USBs - 2 and 3. If you get a fixed 800x600 resolution, it's in the wrong port. (Also, make sure your USB hub is USB3 too!) You can only have one of these plugged in. If you plug in a second, the second one doesn't work. I guess they were lazy and programmed a single USBID number, so Windows doesn't know what to do with the second one. Not bad, refresh/update rate seems OK for office work, but I wouldn't go playing games on it.

I've had three of this type of devices now. the first two worked, but then stopped working after a couple of weeks. Thought I'd try this model - it's a bit more expensive than the others, but the next option for me is significantly more expensive. This loaded well, using the onboard software, and the image quality is much better than the last one i had and a massive improvement on the first (cheapest) one - which was almost unuseable as a result. This model almost seems better than the HDMI connection i have to another monitor. Highly recommended

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.

The item works perfectly! Just note you need to install the drivers from the cd (which is also included in the packaging) before the device works. takes less than a minute to install. No quality loss on the 2nd monitor, so you won't be disappointed.

Ich habe sofort nachdem ich meinen Bildschirm angeschlossen habe gewusst, dass ich diese Rezension schreiben werde. Ich habe einen Lenovo Yoga 530, bei dem über die USBC Schnittstelle nur Daten aber kein Bild übertragen werden kann. Ratlos habe ich nach einer Möglichkeit gesucht, einen zweiten Monitor anzuschließen. (die Hdmi Schnittstelle war bereits belegt) Es gibt hier auf Amazon unzählige Lösungen für USBC zu Hdmi (was bei mir nicht hilft) und auch USB 3.0 zu Hdmi. Bei letzteren findet man in unzähligen Kommentaren die Warnungen vor Trojanern und teilweise spanische Rezensionen die nach der Übersetzung irgendeinen Bildschirmständer beschreiben... Da ich die Erweiterung nur für Office Anwendungen benötige, reicht das Bild und die Verbindung somit über VGA vollkommen aus, sodass ich wirklich Dankbar bin einen Adapter für einen so schmalen Kurs (€) gefunden zu haben, bei dem auch mal ein Markenname drauf steht und man nicht so ein pechschwarzes Ding bekommt, dass schon auf den Produktbildern nach billig Ramsch aussieht. Alternative Lösungen sollten weit über 50/60€ kosten. In meinen Augen inakzeptabel. Daher: Klare Empfehlung! Ob das ganze bei jedem Rechner funktioniert, weiß ich nicht. Aber ich bin ziemlich zuversichtlich. Der Treiber war blitzschnell installiert, einmal neu starten, fertig. Alternativ liegt eine CD dabei, ist aber vollkommen überflüssig, da sich sofort der Explorer öffnet, nachdem man den Adapter eingesteckt hat. Von mir 5+ Sterne und ich glaube man merkt mir meine Erleichterung an.

This VGA Adapter works great and it was very easy to install the drivers. I'm so glad it worked as my old monitor. The only thing that doesn't work when this VGA adapter is plugged in and I'm using the big monitor to Skype, is the sound, the camera works fine but the sound is so distorted that they can't understand a word I'm saying. So I have to turn off my big monitor completely and use the laptop camera for Skype, then the sound comes out clear. At least the big monitor works for everything else, which makes it easier on my eyes.
