Monitor on iMac 27

Depends what monitor you are connecting to.

If it's another Thunderbolt supported monitor, then this cable should work:

Then you need a Mini Display Port to DVI or VGA. Both are available from Apple's online store.

BTW please complete your profile, its VERY difficult to help you when you haven't even told us the version of OS X installed. If you don't know how please follow the simple instruction in Profile Update

Will that work with new Thunderbolt iMacs?

With the sheer lack of compatibility with 2011> iMacs I think it's a worthy question to query some viewpoints.

For example, I was told by a rep. that the 2011 model would connect to the PS3... sigh.

With due respect ssdmac your first sentence is totally incorrect. 2011 iMacs have at least 1 and 27" models have 2 Thunderbolt ports. These ports can be used with Thunderbolt external displays AND the port also doubles as a MiniDisplay port. The use of a MiniDisplay Port to VGA or DVI cable makes the 2011 iMacs compatible with ANY VGA or DVI equiped external display.

The point that a rep said the 2011 would connect to a PS3 is unfounded, anyone can make an error. Clearly this person did and therefore this has absolutely no bearing on the computer's compatibility.

I think it's totally correct - the iMac 2011> doesn't connect to a PC, PS3, XBOX or anything else as a display monitor, it's completely locked down to Apple products only and then some of those do not work either... , which is poor and simply a way of Apple making more money out of their customers, rather than catering (quite easily I may add) to current owners who have a plethora of devices to connect.

Anyyway, I'm glad this solution worked for you OP.

No where in your post did you describe wanting to use Target Display Mode and the OP never mentioned Target Display Mode. Using an external display and Target Display Mode are two totally seperate issues. One is using a dual display Mac, the latter is using the iMac's display as an external display to another computer. One has nothing to do with the other!

Also Apple has been very forthright about what Target Display Mode works with. You assume it's marketing decision and ignore the issue could be technical with Thunderbolt equiped Macs. I don't believe you know enough to know one way or the other and simply unhappy, probably because you did not do your due dillegence.

Anyway this is getting off topic, you can defend it all you like, but I bet 99% of the Apple community would agree that using the iMac as a visual hub for various different inputs would be an extremely attractive proposition.
