Review on 🔌 6-Pack 4K HDMI Dummy Plug for Ethereum ETH ZEC BTC Mining - High-Resolution Virtual Monitor Emulator, Headless Display Adapter Supports up to 3840x2160@60Hz-1080@120Hz Graphics Acceleration by Jason Sisawang

Product works but it's important to be accurate when describing such hardware hence 2 stars. There is an omission and an error in the description.1. The preferred screen resolution is 1920 x 1080 @ 60Hz, so that's what you get when you plug it in; 2. 4k at 60 Hz as advertised does not exist. Below is a list of available modes, starting with running "modetest" on a Chromebox (Linux). The modes are communicated directly via the key and are the same regardless of the system used (Linux, MacOS, Windows or whatever). Hope that helps.
