I'm having no luck getting this to work. Currently using a mid 2012 MBP with the newest TB display. I have an extra Samsung 27" 1920 x 1080 monitor with HDMI input. I have tried the following: Mini Display port HDMI adapter > HDMI cable > Samsung. No luck, my MBP doesn't detect the Samsung. Is there another way to do this? Maybe a straight MDP to HDMU cable (skip the adapter altogether)? Not going to ruin my day if I cannot do this, but wouldn't mind putting that 2nd monitor to use. Thanks!
