I just purchased an Apple TV and when I mirror my late 2013 rMBP to my Samsung TV I get a bit of lag in the cursor/mouse movement but there seems to be no noticeable lag in playback when I play something on VLC with AirPlay on. I was just wondering if this was normal or how to fix it? I've only had the ATV for about 2 hours now so I'm still learning more about it and it's features. Btw, my laptop is connected to my WiFi and ATV connected to my router via Ethernet and my connection is about 50 Mbps down and 25 Mbps up. Thanks in advance!
