Review on 🔌 DEORNA Mini DisplayPort to HDMI Adapter - 4K Mini DP to HDMI Cable 6 Feet, Thunderbolt Compatible - for MacBook Air/Pro, Microsoft Surface Pro/Dock, Monitor, Projector and More (White) by Dennis Reed

Sometimes it works, sometimes it doesn't. I connect it to my Macbook Air from my monitor and it says "signal not found" even though it's connected properly. This is very annoying. It only depends on the day whether he decides to work or not. Don't waste money.
