Wife watches NBC TV shows via the NBC website, but recently we've hit an issue. We were using a laptop (windows 10) plugged into the TV via HDMI with Chrome as the browser, and everything ran fine. But I swapped the laptop out for an old Core 2 box I had sitting around, reinstalled Windows 10 on it (clean start) and set it up the same way as the laptop was - Chrome etc.

 

But it refuses to play NBC videos full screen. Everything else appears fine (TVNZ etc), just NBC wont full screen when you click the full screen icon.

 

Plug the laptop in, and it works fine.

 

Tried with and without AV, ad blocker, etc but no change. 

 

Anyone else hit something like this ?
