I have tried it out and the picture seems fine but every once in a while the picture stutters just a lil bit and I'm wondering if this is because of the hdmi connection. It never stutters in the same place twice. The movies seem fine when I watch them on the laptop alone so i dont think the video files are corrupted. I'm also using just a regular hdmi cable so I dont know if that matters. How do I find out if the laptop supports hdmi 2 and if that's what's causing the stuttering? Will buying a 4k hdmi cable help?
