I have a strange thing that’s happening in my family room. I have an H96 Pro Plus, connected via video switching on a Marantz SR6009 to an LG 79UF7700 4K TV. When playing 4K MKVs only, I will randomly get the screen going blank for 3-4 seconds… This will happen maybe a dozen times during a movie, but it seems to be random. I switched the H96 for a different unit from another room and the problem persists. I’m running CoreELEC 9.0.1. In other rooms, where the H96’s are connected to Sony TVs and no separate receivers, the issue doesn’t happen. It also doesn’t happen ever with 1080p videos.
