[QUOTE="AMACL, post: 1689650, member: 298303"] [b]Thunderbolt + HDMI to monitor works with MacBook, not with iMac[/b] Hello, I had a similar problem as GraceGuitars: thunderbolt-to-HDMI cable from my mid-2011 iMac 12.1 (A1311) did not detect my Samsung external monitor. Combination worked with my MacBook Air and another, more recent iMac. The solution - discovered this morning after trying everything yesterday : push the Thunderbolt plug fully into the computer port. I know, it's the first advice on the list, but the port on the older iMac was 'sticky' and I had to apply more pressure. Maybe the first T-bolt ports were not as good as later ones? Or I just got one that was slightly off-spec? Anyway, a relief. [/QUOTE]
