Review on 🖥️ DTECH HDMI Dummy Plug 4K Display Emulator: Enhance Compatibility on Windows, Mac OSX, Linux (fit-Headless, 3 Pack) by Edward Perez

Some netbooks are set up for use as music players in restaurants and must be left with the lid closed. On recent laptop models, a closed lid has disabled the GPU, causing problems with the remote management software. (not working at all, bugs etc.) Adding a Ghost adapter forces the GPU to stay active, which solves the remote access problem. Since they are used to play music, I wanted to buy USB audio adapters and assign the Music app to them, leaving the laptop's speakers as default for Windows system sounds and other applications. But with the HDMI Ghost adapter, I can set it as the default by sending all non-musical audio to it (virtually muting the laptop) and then just assign music app audio to the headphone jack. That way you don't have to worry about the windows notification blasting out a loud lunch all over the restaurant lol :) So, decent price, as long as they work well I'm happy.
