iMac to samsung "mode not supported"

You're setting you imac monitor instead of the samsung. If the "gather windows" doesn't bring up a second display preferences dialog, try changing the setting as they should be for the samsung (like you have been), and then turn on mirroring (click on the monitor icon in the menu bar to enable this). Once you get same display on both screens, you should then be able to click on the monitor icon and change the resolution for the imac.

Edit: just noticed:you only get the monitor icon in the menu bar if you have "show displays in menu bar" checked in the display preferences. Anyway, you can also turn on mirroring in the arrangement tab of the display preferences.

Perfect, good troubleshooting. This way you'll be able to rule out at least one factor. But a defective adaptor is definitely is a possibility, (I suppose, I've never had these adaptors fail) so it would be good if you could get your hands on another and test it out.

Ha! As usual it's the freakin' cable. I suppose that's included in the "check connections" step, but it gets me all the time too. Routinely I'll have to triple adjust the miniDVI-to-DVI adapter for this old Studio display I'm running. Glad you figured it out. Regards, max
