Ok I have a mac mini 2011 base model with an LG screen attached via HDMI, and a second screen that I want to hook up using the MDP -> any other connection. I've tried all these combinations: a MDP->HDMI cable in 3 samsung tvs (syncmaster 2333HD and two others i can't recall the models of) a MDP->VGA converter from the apple store in a samsung syncmaster 2333HD and LG E2251 monitor a MDP->DVI converter from the apple store in the same samsung and LG screens. Only with the first cable did i get any sign of the second screen being detected, in that display prefs would show the settings for a second screen but i'd never get a picture. With both converters i've never got a hint of the second screen being detected. At this point i'm thinking there is a problem with the mac, so i'm just wondering if anyone else has any experience?
