Review on 👁️ Enhanced Visuals with Headless Emulator Headless 1920X1080 Generation 60Hz） 3Pack by Daniel Murr

They emulate a monitor connected to your computer's graphics card. This is important for very specific applications. For me I use remote Linux boxes, which I log into from my phone using TeamViewer to manage the Folding@Home grid computing application. Without either of them connected to a remote computer, the graphics sent to my phone are low resolution and awful. This dummy connector makes the computer display something to watch out for and makes my remote sessions a lot more productive.
