Hi everyone, I am a bit confused by which resolution is best to choose for videos on my 15", 2013 MBP I got a few days ago. I understand the screen resolution is 2880x1800, but is actually half this, times 2 to make things appear larger. On youtube, am I best to choose 1080, or 1440? There is enough pixels for 1440, but as the os scales up 1400x900 x2, I don't know if I will actually be getting 1440, or even 1080. 1080 definitely looks much better than 720, and I think 1440 does, but am unsure if this is psychological with 1440. Thanks for your help, Conan.
