Hello, I have a laptop Lenovo Y50-70 and when I connect it with TV through HDMI, I have several problems . One of them is, that there plays no audio in the TV, even when I select it as default audio source in Windows sound manager. Video works quite fine - I say quite, because when I start gaming (--> games that powers the Nvidia GPU), the games are just in 30Hz and there is also a big input lag. And the last problem is, that when I want to duplicate screens (to see the same things on both), the one built in my laptop has lags (similar to turned off V-Sync in games - those tears). Thank you for help!
Software/Hardware used: Lenovo Y50-70 FHD with dedicated GPU Nvidia GTX 860M, Windows 8.1 x64
