Qnap 51+ series are fairly old. Maybe better to consider 53Be if still available. These models would have better 4K support via HDMI. The latest models are 53D with newer LAN ports which is a good thing to have while we are moving towards WiFi6.But you can also stream via DLNA or any network-based streaming app. Then HDMI is not that important.The idea about two NAS systems in remote locations is great. You can set up automated sync tasks and keep your data duplicated effortlessly. This is a much better approach then RAID. But that is needed as well.I hope this helps.
