You may find it difficult to find someone with that exact hardware to confirm for you. Very nice btw. As with most things state of the art, your hardware should be able to handle just about anything you want to do with it. USB 3.1 Type C Thunderbolt connector is yet another port to consider. Some FYI to help you. I understand it is no comparison.

HDMI 2.0 does support MVC 3D Frame Packed. I know because all my hardware is HDMI 2.0. This forked build does work if everything is set to 1080p. This is undesirable with a 4k system imo. PDVD works well with 4k settings. However, I'm using Intel with NVidia. Nvidia GPU capabilities are different than Intel graphics. If I was you, I would concentrate on getting this build to work. You may find PDVD no different because of that port. Trying different adapters should be a last resort imo. Though it may be evident, have you set Kodi to 1080p just like you set Windows to 1080p globally? Have you tried a couple different drivers for your 620? I ask because last time I looked for Intel drivers, they offered two. Only one of the two was the correct driver. That was using the utility with hdmkv. I don't know how it's setup today? The good news is, your display is trying to switch into something.
