Hey all, So I've run into a couple snags trying to hook my rMBP up to my 2560x1440 display. First, I tried using HDMI, but I was limited in resolution (which is odd, as my display is HDMI 1.4 compliant). Next, I tried the MiniDP > DVI adapter, but was limited in resolution there too. (Side tangent: WHY does Apple sell a single-link DVI adapter that includes dual-link pinouts?! That adapter should *not* include the center block of pins, suggesting it is dual. It tricked me into thinking it was dual, which is why I bought it. Nowhere on the product page does it say it's only single-link. I couldn't believe how deceiving that was.) What's the cheapest way I can get my laptop to output 2560x1440 to my display? I know I can do it with the $100 dual-link DVI adapter, but that's bulky and very expensive. Is there a cheaper option?
