Worked perfectly for 3rd monitor

I bought this adapter to interface my third monitor with an ASUS F2A85-V Pro motherboard using AMD Eyefinity. It worked perfectly out of the box. Using the AMD display driver has allowed me to have a desktop continuously spread across all 3 monitors. Couldn't have been easier. BTW, the DVI connector is female so it works with a standard M-M DVI monitor cable.

I bought this to connect my 2nd computer  monitor (HDMI) to my new video card (only one HDMI port, the rest are DisplayPort). It arrived quickly, fits perfectly, image and audio quality are perfect.

I was having an impossible time getting 3 monitors to work with my docking station.  The limit appeared to be 2 monitors and my laptop screen.  I purchased this item thru amazon and it was delivered fast.  Within minutes of plugging this into my computer and loading the drivers, I was up and running with 3 monitors.  I do not have any issues of lag on my 3rd monitor but I also do not use my system for any advanced games.  For the money, this is a great product!!!

I bought this for a new external monitor for my computer.  Worked perfectly!!

I bought two for two different size monitors and they're great. Perfect for what I needed and a much better solution to what I had in mind to do to overcome a sight problem where the monitors block my view. My monitors are slightly older 27" (read heavier) and a 24" and both reside on the same desk. Construction of the swivel pads are decent enough. They don't slide on my smooth surface desk and the rotating the monitors is easy. For folks needing a product like this, these are excellent. I have had mine for a couple of months, no issues and frankly unless they stop swiveling I don't see where in the future an issue could come up.

I got this to install a 3rd monitor on my Dell Optiplex 7010 and it works fine.  I can now use the 3 monitors in extended mode.

This Mini DisplayPort to HDMI cable worked perfectly when used with my graphics card and monitor. I would buy it again, absolutely, as it fixed a tearing screen issue from my previous one.

This works great for extending my display to an external monitor.  No issues at all with it after a few months of use!

I bought this device to connect an additional monitor to my Intel NUC5i5RYH. I already used the display port and the HDMI port but I needed to connect a 3rd monitor and was not able to connect it via the Displayport hub. I ran into an issue at the beginning where the driver wouldn't pick up this device but after a fresh windows 7 installation all was well again (something must have been corrupted in win7 HAL). I also contacted the support and they were very helpful and responsive - they definitely won't let you hanging.

USB 3 was a must for me as I have no interest in running a screen off USB 2. I've done that once and the slow response of the screen becomes unbearable to work with. Just moving a window on USB 2 shows "ghosting". Luckily this device is USB 3 and it works great. I had absolutely no issues with how the graphics are displayed and the responsiveness of this device.

Only test remaining at this point is to see how it holds up against time...

Works fantastic for a commercial 3-monitor operation, much better than it worked with 2 separate video cards. Thank you, Sapphire, for making this!

This did Exactly what it was meant to do add another screen onto my 2nd PC if you don't have a Drive Bay Remember the Link to the Download for the Driver meant for this Cable is on the page where you Buy it on Amazon.

I was relieved after getting this adapter and it worked perfectly. Feels solidly built no mess signal conversion. I'm using a 3 monitor setup with a r9 290 and even though r9 series cards are supposed to be able to use 2xDvi and 1 hdmi it wouldn't popped on this little gem and magic happened

Worked perfectly!  I was a bit worried at first since one monitor is heavier than the other, but the weighted base works perfectly.

Installed easily and works brilliantly, allowing me to run four displays on an old laptop. I added this to my HP DV7t-7000 laptop purchased in 2012 with 1920x1080 native resolution, running Windows 10. I thought it might be too old to drive a 3840x2160 monitor even this this adapter. I was already running three screens, with the laptop display and two 1920x1080 monitors plugged in the laptop's VGA and HDMI video outputs. I connected this Startech adapter to a new LG 4K 3840x260 monitor and it worked instantly with no setup required. I plugged the HDMI cable of the other monitor into the second slot of the Startech adapter and it too instantly connected with no setup required. I never expected that. So I now have three 1920x1080 HD displays and one 3840x2160 4K display all running simultaneously from my six year old laptop. Also worked great in 4K when plugged into a Samsung 4K TV. Five stars for the engineering and execution on this inexpensive adapter!

This USB display adapter just works!  I connected it, booted up, and Windows 7 started using my 3rd screen with no problems.  As expected, I had to tell Windows where my monitors are located in relation to each other, but it detected each monitor & selected the best resolutions for them.
My Dell 2007 WFP monitor definitely looks better using the DVI connection provided by Plugable than the VGA  connection I had been using.
VGA and HDMI adapters are included in the package if I need them for future use.

Worked exactly as expected.  Used this to connect a Raspberry Pi 3 to an older monitor that didn't have HDMI, only VGA and DVI-D.  Worked like a charm running the HDMI cable from the Pi to the adapter connected to the monitor.  The screw-down connectors can be a bit hard to tighten down since they're so close to the adapter body AND don't have a flat-head groove in the end for a screwdriver, but other than that, they did just what I needed.

Recently bought a Lenovo Tiny M900 with 3 DisplayPorts. Needed an adapter to use HDMI cables for both my monitors. These work perfectly.
