Review on StarTech.Com USB 3.0 Or USB-C Dual HDMI Adapter For Windows & MacOS, 2X HDMI Displays (4K30Hz/1080P), Integrated USB-A To C Dongle, 4In Cable (107B-USB-HDMI) by Rodney Harris

I am using this with and acer nitro 5(Ryzen 5 and GTX 1650). I have 2 32" external monitors. One direct to HDMI port on the laptop and the other to this device which is plugged into a usb 3.0(blue) port. I was expecting lag and jittering, but mine is smooth as silk. I can watch YouTube on it and it looks great. I know some have had issues with lag but not on mine. It appears to be as smooth as my HDMI monitor honestly. Your mileage my vary but mine is great and I would purchase again.Bought with my own money and not paid to leave positive feedback. Hope this helps!
