BUG – Unable to play 720p & 1080p videos (OpenElec)

Hi! I’m running Kodi 17 on an Asus Chromebox running OpenELEC on a Panasonic 720p plasma TV.

For some reason, I only get a black screen (no video or audio) when trying to play 720p and 1080p HD videos?

480p videos play just fine.

I tried plugging in my laptop which is running Kodi 16.1 into the Panasonic’s HDMI and it works just fine playing 720p and 1080p HD videos.

So, I think it might be an issue with Kodi 17?

I would downgrade it but I’m running it on OpenELEC and have no idea how to downgrade Kodi on that.

Any tips or suggestions appreciated!
