I have a Dell UltraSharp (2500 x 1500px) screen. It's lovely and is a nice safety net for the rMBP's blurry Photoshop resolution. Well, I THINK it is. Because I'm confused. The rMBP has a HDMI port on the side. The Dell's HDMI plug is really bulky and doesn't fit. Is there an adapter for this? How does one make these two play nicely?
