So basically I have been in hell trying to pick the right combination of macbook and external display. I am a PhD neuroscientist student so I do a lot of coding, data analysis, reading, and writing on the computer. In this way, power is important. I also travel often from the lab to the library, and even to various coffee shops. In this way, portability is important. I have listed some ideas I have had in both but feel free to suggest something else. Especially in terms of external display. Computer 12'' Retina Macbook Air - $1400? 13'' rMBP (Base) - $1400 13'' rMBP (Upgraded to 16GB Ram) - $1600 13'' rMBP (Upgraded to 16GB Ram & 3.0 Hz i7) - $1900 15'' rMBP - $2100 External Monitor Ideally I'd like it to look as good as the retina display 28'' 4K Samsung Monitor (UD590) - $500 40'' 4K LG TV (40UB8000) - $600 This TV only supports 4 2 0 ChromaOther monitor?
