Alt Mode only supports up to HDMI 1.4b, not the new HDMI 2.0 standard. This means you can get a few of the features of HDMI but will need to sacrifice some of the others. Here’s a quick summary of what you’ll get:
· Resolutions up to 4K Ultra HD (3840 x 2160).
· Audio Return Channel (ARC).
· Support for 3D videos.
· HDMI Ethernet Channel.
· Consumer Electronic Control (CEC).
· Dolby 5.1 surround sound audio.
Apart from streaming simple audio and video, current USB-C-to-HDMI adapters don’t support the other features mentioned above. That’s why the new Alt Mode standard is so nifty — it guarantees that everything will work just as you expect it to.
Meanwhile, the lack of support for HDMI 2.0 will mean that some of the newer features won’t be available. For example, HDMI 2.0 raises the frame rate of 4K videos from 30 FPS to 60 FPS. It also supports High Dynamic Range (HDR) video technology, which is one of the more useful TV features to come out in recent years.
