Hey All, There seems to be quite a lot of conflicting information floating around (some here and other sites) about how exactly to connect a Macbook Pro up to 2 external monitors. So I'd like to get some definitive answers for myself and others that may be in this situation. My setup: - MBP 13" mid-2012 - OS X 10.9.2 - Intel Core i5 - Intel HD Graphics 4000 - 2 x ViewSonic 24" 1920x1080p monitors (identical) - Zotac MDP2HD dongle (mini display port to dual HDMI) Everything plugged in out of the box actually works ok, however my issue is with resolutions. Out of the box the external monitors get displayed at 2560 x 1024, which is a horribly stretched resolution and almost unusable. After doing a bit of reading, I understand that the MBP treats the 2 external displays as 1 single display, seeing as its only coming from 1 source, so I guess the only option is to experiment changing the resolution on the 2 externals to 3840x1080. I have tried SwitchResX and a few other tools to force the resolution change without any real success. I would assume I could force 3840x1080 using software and everything would simply work, as it seems to have for some people on here, except I get blank screens and nothing I try seems to work. I'm not even sure what I'm trying to achieve (3840x1080 across both monitors) is actually even possible, after checking the MBP tech specs on Apple's website it says the following: Although some people seem to have this setup working just fine, am I correct in assuming that the closest I can get on this MBP would be 2560x1080 or am I missing something obvious so that I can force the desired 3840x1080 ? And if so, how does the Matrox DualHead2Go adapters differ (their site says its compatible for my MBP) ? Do they have a separate GFX card built into the adapter that would upscale to 3840x1080 ? Thanks in advance! Phill.
