When I first got my Dell XPS 13″ 9350 (Developer Edition), I needed an adapter so that I could power an HDMI display via the laptop’s USB-C port.
After poking around for a few minutes, it seemed like the DA200 USB-C to HDMI/VGA/Ethernet/USB 3.0 adapter was the right choice. It works with plenty of Dell XPS laptops and says things like “USB-C to HDMI” in the name of the adapter.
I was wrong!
I have no idea why I was wrong, but thanks to the answer on this Ask Ubuntu post, I learned that the DA200 is not exactly what it claims to be. The only way this adapter actually works with a 55″ TV or similar is at 800×600 resolution. Definitely not what you expect when connecting HDMI.
After reading that post, I purchased the Apple USB-C Digital AV Multiport Adapter. It has only a 2 star rating on the Apple site, but it worked immediately and powered the 55″ TV as expected over HDMI at 1920×1080.
Hopefully this post helps make it more obvious via Google that the DA200 is the wrong adapter and the Apple USB-C Digitial AV Multiport Adapter works great!
