Review on 🔌 USB to HDMI Adapter, HD Audio Video Cable Converter, USB 3.0 to HDMI for Multiple Monitors 1080P, Windows XP/10/8.1/8/7 Compatible (Not Mac, Linux, Vista, Chrome) - Gray by Bart Elbrink

The product looks smooth and works after installing the drivers, but I noticed an input lag of about 100ms which is pretty bad. I tested this on two of my monitors, which have an average response time of 1ms. I duplicated the image on both my primary monitor (right) and the monitor the adapter uses (left). As you can see on the screenshot (from the video) I used a timer to check how far one is behind the other. You can see that the difference between the timers of this frame is 100ms (12.256 left, 12.353 right). Using a monitor with such latency seems totally unacceptable. And I'm using a USB 3.0 port, otherwise the resolution would be 800x600. I'm sure it would be fine for a TV, but it definitely won't work for a desktop monitor. I'll return this to find the adapter without that kind of lag.
