Thanks for your help so far! Same here. No worky. SMC reset, regular restart, nothing. I did that ridiculous Option trick for Detect Displays, and nothing. This sucks so much. I am not wondering of Steve Jobs really did have that much influence on things. Many bugs. Been in touch with Apple twice.

Macbook Pro HDMI port not working? Here's a quick fix!

I was advised that a Thunderbolt cable would work. I bought one at the Apple store. The only port the cable fits into at the Dell is called, DPin. I did the option thing in the Display screen. Hi Everyone — I have solved this problem with the help of telephone support.

Initially I was disheartened after reading all that has been written in this particular article comments section, but luckily I managed to crack this. I had earlier used a samsung with the mac mini, and straight out of the box, it matched with the samsung. It appears that this leaves the mac mini with the memory of the samsung. That did the trick partially. Then i restarted the mac mini, as before. Everything now sings. That has stayed undisturbed.

The less elegant way to do all this is to have a Apple TV connected by ethernet or wifi to your router, and a mac mini to the same router, and then the Sony TV will accept anything your mac mini has, provided it is iTunes compatible. If the apple TV is jailbriken, then you can use some other formats and a whole lot of other programs.

There is plenty of literature around the how and why of apple Tv jailbreaking. I had the same issue with my Macbook Pro and LG display. I guess something needs to be cleared in order to let the mac connect to a second device. Anyway, I had to run through the procedure above twice, but it worked.

Warning tho, it cleared my wifi connection and I had to dig around for that password I had on an index card. I have no idea yet what else may have been cleared, we will see. But it works fine when I use VGA monitor cable. Great tidbit. Well done, to the point.
