Screens flickering on and off and making machine unstable

so I have been using the hdmi adaptors (3 of them to add 6 extra screens) and this has worked fine for the last year! now it’s starting to flicker and cause instability throughout the day. I have made sure all drivers are up to date, etc… but still having no luck. Any chance you can help?

Hello,

Welcome to the Plugable forums and I can certainly assist with these flickering issues with these three UGA-HDMI-2S USB Graphics Adapters. There are a few troubleshooting steps that we can take that I’ll parse out in numbered steps.

Could you please try these following steps:

  1. Power cycle the adapters, please unplug the adapters from your PC and wait about 2-3 minutes before plugging it back in
  2. Lets update the firmware for these adapters. To do so we will need to install the Silicon Motion drivers while the adapters are connected to your PC. Download the latest Silicon Motion drivers here: https://plugable.com/pages/siliconmotion
    1. Since the drivers are already installed the installer will give you an option to “uninstall” the Silicon
      Motion drivers
    2. Restart your computer
    3. Windows should automatically install the Silicon Drivers through Windows Update and thus updating the device’s firmware

Please let me know if these issues persist and if that is the case please reach out to us directly by contacting us through our support page and reference ticket# 440283 here: https://plugable.com/pages/support
