StarTech.com USB 3.0 to DVI / VGA Adapter - 2048x1152 - External Video & Graphics Card - Dual Monitor Display Adapter Cable - Supports Mac & Windows (USB32DVIPRO)

You NEED the USB3 DisplayLink version for an external monitor display with no lags running at 1080p60fps. I had the older USB2 DisplayLink and it was so laggy, so with this upgrade, all that is gone. Don't wait, it's worth the money. My default setup was limited to 2 external monitors and the laptop screen. But I really wanted 3 external monitors and laptop display for a total of 4 displays and this new setup just works... on my Chromebook Acer Spin 713, no drivers/software to load, and no lag even with HD video. This is absolutely the best device ever. Also, since the DisplayLink functions as its own video card, you might be able to add even more monitors if you wish... but make sure you have a powerful laptop/computer to push out the graphics. I highly recommend this device for anyone wanting to add extra external monitors especially on Chromebooks.

I went through a few of these to try and extend a 3rd monitor from my HP laptop. None of the USB-C versions worked on it. Not even the expensive docking station for HP! So I tried this USB-A one and I just plugged it in and boom, screen on! Did not create any drag on my system nor any flickering which I have experienced with other laptops with screen extensions. Very satisfied!

First, before you buy, make sure that your current computer does not already support dual monitors. If you have a display port (DP) it might support dual monitor connections and all you have to do is get an adapter. Also, if you have both a VGA port and a DP port, your computer definitely supports dual monitors and you do not need to purchase this device. The same goes if you have a graphics card that has something like a VGA port and a DVI port. So check your computer first to determine that there is no other way to connect a second monitor before you buy this.You should know that this is a graphics card that connects on a USB port and capabilities are limited even compared to on-board graphics cards found embedded in a computer's mainboard. Over the past couple of years I purchased a few of these for work because our employees keep asking for a dual monitor setup. It works well for things like spreadsheets and documents but if you are looking for a second monitor to play games on, this will not be for you.Finally, note that this will work with Windows 10 but previous versions of this device from Star Tech that I purchased for Windows 7 do not work with Windows 10 and Star Tech does not offer drivers for them. Hopefully, this being USB 3.0 will be supported by future versions of operating systems and Star Tech will produce drivers for them. This is not a plug and play device so before you connect it to your USB port, make sure you download the latest drivers for it from startech.com and install them. Then plug it in.

I attempted to use this with a QGeeM Mini Display Port to HDMI converter and 27" Apple Cinema Displays and the image on the screen seem transpired and it had a ghost effect to it when any window was moved as if the monitor had the imaged burned into it temporarily. I've tried several adapters and 4 different Apple Cinema Displays with the same result. I returned this and immediately bought the Plugable dual display dock and it worked absolutely flawlessly both over display port and HDMI even with the QGeeM adapters.Link for the Plugable 4K DisplayPort and HDMI Dual Monitor Adapter for USB 3.0 and USB-Chttps://www.amazon.com/dp/B08F2SZQYX/ref=cm_sw_em_r_mt_dp_GMHRY3VQG3GTJFCD49JS?_encoding=UTF8&psc=1

I wanted to attach two extended displays to my MacBook Air 2015 (running Monterey) and had a terrible time finding a solution until I came across a YouTube video that directed me to this product. One display was already plugged in to the mini-DVI port. I bought this to plug my 2nd monitor (HDMI output) to my laptop's USB port. My monitor has a VGA output too but I decided on the HDMI because it was cheaper with faster shipping. I bought an HDMI cable too.It arrived fast and took me about 15 minutes to set up. I followed the directions and easily downloaded the appropriate driver from the StarTech website. It didn't work immediately even after I rebooted my laptop which made me worry it wasn't going to work at all. I then tried opening up the DisplayLink driver file directly from my applications folder. Once I did that, it prompted me to adjust a security setting giving permission for the adapter to access my computer's video (or something like that). Once I changed the security setting, it immediately worked. The adapter is expensive but I am so happy to finally have two displays!!

Works great! I have an older MacBook Air, 2015-2017 and I wanted to be able to use two dell monitors. Since my Mac has an intel chip, I was sure I was able to run for two but I only have one mini display port. It’s a teeny bit laggy but not so much to disrupt work flow! Would recommend!

Pros: Win 10 found driver, no problem. I got the second monitor over USB 3. Worked with USB 2 even through USB HUB.Cons: Win 7 required drivers. Included disk had outdated drivers. After installation, had to update drivers for both Win 10 and Win 7 to get audio through adapter.There is visible delay on screen connected with this adapter ( no matter if it's connected to USB3 or USB2. If mouse hovering over desktop application there's no delay, but if you go over simple internet page, mouse pointer just keep sticking from spot to spot, especially, when it hovers over any link. This doesn't happen with the same co conditions, but when monitor connected directly to HDMI laptop output. There is no delays in that case. The most annoying thing is when monitor, connected through startech adapte,r could not wake up after sleep unless I physically reconnect it. There was delay at first week or two aster sleep and now this. I would return it, but window of return is closed right a week later after last day of return. I wonder if this company survives on this no return window. I switched to "Cable matters" now. No problems with wake up so far. Screen delay is a bit less.
