Review on 💻 CompuLab 4K Headless Display Emulator Ideal for SEO by Donnie Boss

If you're running a Headless Mac Mini and want to share the screen from a large monitor or 4K TV, this is what you need. Plug it into your Mac Mini's HDMI port, download the free Display Menu app from the Apple Store, and run it on your Mac Mini. Then, when you share your screen, you have a large number of resolution options in a simple drop-down menu. I've been able to share the screen from devices ranging from my 13" MBP to a 4k TV to a 27" IPS monitor and there's always one resolution available. Note. Remember this item costs less than $10. As mentioned in several reviews, 4k is slow to update. It works great for most things, but you probably don't want to play games or watch videos in 4k. 1920 x 1080 can run at 60Hz.
