Hi I have just received my new 27" Thunderbolt display and I`m loving it! I currently use this with my 13" rMBP (Late 2013 8GB) open to give 2 displays. I have a spare 24" 1080P LG monitor that I would prefer to use as the secondary display (over HDMI as it has no displayport connector. Is there any reason I cannot use my MBP in clamshell mode on a shelf below the desk and run 1 x Thunderbolt display and 1 x HDMI display? Will this work? If so is it likely I would run into overheating issues? I don`t push this machine hard, streaming video is probably as hard as it will ever work. Thanks for any advice.
