KotiSIG USB to HDMI Adapter for Multiple Monitors 1080P Compatible with Windows XP/7/8/10 （Black）

The install was quick and easy. Windows detected the USB device and opened a new folder to install the driver. Followed the setup instructions and a few seconds later, my second screen was usable.However... Sometimes the mouse icon gets strange ghost images on it. One time, I had two mouse pointers overlapping each other. Another time, it was a vertical scroll icon on top of the mouse pointer.But the most annoying part is that the secondary screen will not shut off. My PC shuts off monitors after 30 minutes, but this one stayed on. Maybe it has something to do with my USB power saving options? But I have a different brand adapter that works fine without issue.Bottom line, if you just need this for a workstation and need the cheapest option available, it will be fine. But its got more quirks than a Jonny Depp character and it isn't nearly as entertaining.

Bought this for a laptop that didn't have a proper USB-C to run display. It works as advertised. No screen flickering like USB 3 to VGA adapters. Convenient installation of software and driver since it's built into the device. Only 4 stars because if you run an application as an administrator and Windows prompts with a pop-up, the screen this is attached to stops displaying. After a password is entered all items that were arranged on the multiple displays go back to 1 screen. Too bad the software can't continue to display.

I have a HP Pavilion DV7 with a 15" display which I use for one of my monitors. I have two Dell S2318HN 23" displays. My HP only has one HDMI port. I bought this adapter so I could connect both Dell monitors to my laptop. I followed the instructions exactly as explained in the user guide (included with packaging). After loading the driver that comes as an .exe file on the adapter and rebooting the laptop, all I had to do was plug my second Dell monitor into the adapter. After that I was able to change the resolution to 1920 x 1080 to match the Dell monitor that I plugged into the HP HDMI port.The display works flawlessly. Both Dell monitors perform exactly the same. If I put my laptop to sleep, both monitors automatically turn off. When I wake the laptop, both monitors automatically wake.I couldn't be happier.

It does work, but lags a lot when moving folder windows, files, etc. I can’t blame the speed of usb because J5 sells a similar device and theirs has no lag at all. If you don’t mind slow refresh speeds and just want something that works, this will do the trick. I also had to adjust the resolution after installing it. The default was too low.

Setup sheet has very small type -- Google drive interaction with the files on the device led to some confusion ( as setup files are on mini drive space on the device itself). But install went well after I closed google drive.

I got this to hook a second (third including laptop screen) monitor up to my laptop. It works but you need to make sure to download the driver or it won't connect. Also it's a little laggy but I'm not doing anything major on that screen so it's fine for me for now.

Lo único malo, que no sé si solo me pasa a mi, es que si tocas el cable, se desconecta momentáneamente el dispositivo.

This USB to HDMI port works for allowing an additional monitor, however, the picture quality is not good. There is a huge difference between the monitor that plugs directly into the HDMI port and the one that goes through this converter. If price is an issue, settle for this, but if you can afford something a little better quality, do that.
