Review on 🔌 StarTech.com Active Mini DisplayPort to HDMI Adapter - 4K 30Hz Converter - Compatible with Mac/PC - White by Brett Jarvis

I have a 34 inch widescreen display with 3440 x 1440 and a Surface Pro 6 (and dock). All other MiniDisplayPort adapters limited my resolution to 1080p. Tip for Surface Pro users: I had to take extra steps to get the correct resolution. First I had to connect directly to my surface and then go to the dock. I also had to return my graphics card adapter. I suspect that last part is because I used to use a DisplayPort adapter.
