Widespread reports of serious compatibility issues with many 4k devices due to HDCP handshaking issues with the pro.
Also reports of actually WORSE performance on 1080p for some games, as reported by Digital Foundry.
Shaky start for the Pro, I hope things improve soon...
No issues with my 4K HDR Samsung. All is normal here.
Edit: From the reports I have read, Vizio and LG OLED TV's are the reported models suffering from the compatibility.
