Review on JSAUX Mini DisplayPort to HDMI Adapter: High Quality Thunderbolt Mini DP to HDMI Converter for MacBook, Surface Pro, Monitor, Projector and More-Red by Kenny Hrdlicka

Good quality key for the price. Very well made and still able to give me a 120 fps refresh rate for my 4k gaming screen. The only downside was that I had to disable the Thunderbolt document in order for the computer to recognize the new display adapter. I don't know if this is a Dell issue or an adapter issue.
