Everything seems to be working fine which is why I’m confused. The sky go app works fine on my computer but then laggy when I use the hdmi cable but everything else works fine using the hdmi cable with no lag
I am definitely not a Computer Expert but I think this is more of a software issue that cannot be fixed directly by you - but the developers of the app. If it's a smart TV I suggest you download the app on that but you probably would've if you had one
E.g this wouldnt happen on a desktop.
