Rated 5 out of 5 byNickD_CA19 from Awesome DongleI have used this USB to HDMI adaptor with several computers and it always connects and works well. The adaptor comes in a box about the size of three DVD cases. The adaptor's size is slightly smaller than the palm of my hand. The cable coming out is about a foot long and very flexible. It comes with instructions but I don't think they are needed as you just have to plug it in to start using it. When I connect this device to a new computer it takes about 30 seconds to detect, install and start working. Future connections only take seconds before it is working. The response time is very quick for the display and I can't notice any lagging. Only one port works with 4K, but I can use both ports with 1080p displays. I like the fact that I can connect this to any computer and I don't have to worry about what type of video out port the computer has.This adaptor works consistently well and quickly. I received this product in exchange for an unbiased review.

Rated 5 out of 5 bypdx971 from Works Exactly as DesiredPurchased this to add a second monitor to my HP Envy All-In-One system. I use this computer for work at home and needed another display. Setup was easy. The only variation from the directions was related to the USB Video Adapter Icon. I do not have an icon displayed on my System Tray. I viewed Devices, right-clicked the monitor, and edited the settings. Was able to switch the monitor order as desired. Everything is working as expected.

Rated 5 out of 5 byAndrew11 from Great adapter.This adapter is great for connecting to 2 HDMI monitors. One in 4K HDMI and one HDMI (it’s hard to see, but it’s identified under each port) The adapter installs on its own (Win10) and works perfectly each time. I’m very impressed with the quality of the video signal from an adapter so portable, and without having to mess with drivers!I received this product in exchange for an unbiased review

Rated 5 out of 5 bydjluislatino3 from Easy and smallThis adaptor is an awesome plug and play, very easy to setup under Windows 10 and I use it for demo presentations when I'm on the road to visit prospective clients. The quality of the image is great and I didn't experience any freezing or delays.The adaptor itself comes in a small box and fits on my ultrabook bag. The instructions are well explained but I doubt you will need it.I haven't tried it on a MAC but for Windows users, it is a GO!"I received this product in exchange for an unbiased review"

Rated 5 out of 5 byjhuber123456 from USB to Dual HDMI Adapter Made EasyI have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use. This unit lets you add two independent HDMI displays to your computer using a single USB 3.0 port. Both displays I connected had exceptional picture quality, without tearing or pixalization during fast motion video. This unit provides smoother scrolling, higher resolutions and better overall performance than other USB adapters I have tested.

Rated 5 out of 5 byMacphoto from Easy installation, great picture, just awesomeInstallation of this was so easy. Plugged it in and Windows 10 did its thing and instantly installed the video and audio driver for this device and voila it was up on the screen. Startech gives you instructions for getting this device to work but I did not need them, it just worked. The image quality was good and there was no latency issued that I experienced for basic work.Great little product !

Rated 5 out of 5 byEnrico USA from Perfect recommendation and communicationsMy laptop has HDMI output and could not find a splitter to extend to two monitors. I called StarTech support and this gentleman (Harish) guided me to the right product after some technical questions. AND, now not even using the HDMI just one of the USB ports! Very clear communications with these guys.
