I was able to use 2 of these to make my old laptop run 3 screens, there was no install or anything, just plug it in and it works. Both monitors are highly responsive, and it's only when I have a YouTube video playing at full screen that I can even tell what monitors are usb. Fantastic product would highly recommend.
PROS: Plug and play Fast response time for usb monitor Works on old laptop Supports VGA/hdmi/dvi
Open the box. Plug it in, open the Windows screen resolution dialog and drag things around to fit. Get to work. Forget about it. That about sums up my experience with these.
I have a central 27" monitor driven directly from the laptop's DVI port, and four other monitors (19" portrait mode) all driven by these. I'm a designer, and always have lots of windows (email, browser, documentation, CAD tools, terminals, text editors etc) open all the time, and being able to spread things out over multiple monitors has been a big productivity enabler.
These appear to be either a re-badged or a minimally-modified DisplayLink reference design. When I changed laptops earlier this year I initially had a minor display driver issue, but I contacted DisplayLink directly and they were able to sort it out within an hour.
Yes, being USB 2.0, it is possible to see a small amount of tearing if I drag a window quickly. So what. I'm not playing twitch games, I'm working, and only a small portion of the screen is being updated at any one time, so this is never an issue. That being said, I've occasionally had video running on one of my external monitors, and I've never noticed a quality issue.
PROS: Easy to use Quick to set up Works great Good support directly from DisplayLink
Super easy to connect and set up. I didn't even bother looking at the instructions (which would be cheating anyway). Just pulled it out of the box, chose the right connector for my monitor (DVI and pulled it I to my laptop. Presto! Two monitors with extended desktop. Love it!
PROS: Fast and easy to setup
No need to read instructions
Includes multiple connectors to fit many different monitors
CONS: I balked at the price, but now that I have the device and everything works so well, I can't complain much.
I drive two monitors - one with a thunderbolt-vga adapter and the other with this adapter (using the vga connector). The usb-adapter driven monitor works as well (maybe even better) than the other one. I don't notice any lag when mousing or selecting on the usb-driven monitor.
Very happy with this. I bought 2 Dell monitors that I thought would work via USB but that wasn't the case. So I had to buy this adapter to convert from DVI to USB so it's easy to work with my laptop. 2 of these and 2 DVI cables and bam, good to go!!
I use a laptop in my work and have an external 23" monitor attached to it. This allows me to work on spreadsheets and search the web for information on a big monitor. I had always wished that I had a second large monitor to work with so that my Outlook messages were easier to read than from my tiny laptop screen. I didn't know that these USB-to-video devices existed until I ran into a guy at Frys bragging about them. I found several on Monoprice and the online videos made it easy to find the right one for me.
It came quickly - I live in California, so the overnight shipping deal was perfect. I hooked it up and never even used the accompanying CD to install drivers on my Win 8.1 Dell. It quickly installed software (How, I'll never know) and recognized my monitor attached to it.
The only quirky thing is that when I restarted my computer the next day, the attached monitor never came out of sleep mode. I had to unplug if from the power supply, then re-power it for the monitor to wake up. I've noticed that a few times, but it is not a big issue.
I thought that perhaps the response time on the monitor might be sluggish, but I don't notice any lag whatsoever... I'm not a gamer, so your mileage may vary.
PROS: Easy setup - didn't even touch the CD that came with the device
CONS: Just a little finicky with Win 8.1 - sometimes I need to start the attached monitor last
I use these units at my church on various machines running both Windows and Mac OS X and have been very happy with them. This one never worked from the get go. :(
I installed the software for the device on my Mac, (even went and got the latest version from the DisplayLink website.) Went through the restart process then plugged it in and the Mac doesn't even recognize it. (IE. it doesn't do its detect displays flicker.)
I tried the device on my Windows 7 machine, it auto detected that it was a DisplayLink adapter, installed the latest driver and said it was successful but there was no output on the display.
Next, I downloaded the DisplayLink Support Tool. I keep getting the following message: "We have detected that the DisplayLink device has not booted up correctly and will not function. To recover the device: Unplug all cables, Connect Power (if required), Connect the USB cable, Connect the video cable. If the problem persists then the device should be returned to the vendor for a replacement."
