I'm in the process of updating my external monitor configuration to run off a MBP Retina and I'm not sure if I should use a TBP + a 27" Dell monitor (that can do 2560 x 1440 to match the TBP) or three 24" inch monitors at 1920 x 1080. Ideally, I would love to have three displays at 2560 x 1440, but it seems that current MBPR's can't do a third display at that resolution through the HDMI. I'm concerned that running a monitor at non-native resolution or having 2 monitors at 2560 and 1 at 1920 will become annoying given that I stare at the computer for 10+ hours a day for my job. Also, I really would like the additional features of the TBP, so it would be helpful to have that as part of the configuration. So I'm not sure which is optimal - 1) TBP + 27 inch Monitor at 2560 x 1440 2) TBP + 27" (2560 x 1440) + 27" (1920 x 1080) 3) 3 24" at 1920 x 1080 Any advice?
