Hi, I am using a 13-inch Macbook Air and I'm wondering how many displays it can support, including its own. I currently have a 900p display, and I received a 1080p display. So actually, I am running 2 external displays, one with the thunderbolt port and one via USB. However, I'd like an actual big display, and I was considering the thunderbolt display. However, I was wondering, could it be possible to use all four displays at once? Like, Thunderbolt Display via Thunderbolt (obviously...) and my 1080p display via daisy-chain and my 900p display via USB, while also using the Macbook Air display, or I would have to let go of one of my displays? Or could a Retina Macbook Pro 13 inch run these?
