Got a fancy new Mac with some flavor of DisplayPort connector and a shiny new copy of OS X 10.6 Snow Leopard installed? If you do and you also happen to hook said Mac up to an HDTV via an HDMI adapter, then head on over to System Preferences to check out the latest uncovered Snow Leopard nugget of awesomeness.
Three new resolution options are now available for your HDTV-viewing experience: 720p, 1080i, and 1080p. This should be good news for anyone rocking the HTMac set-up, or even for anyone who wants to check it out and may not be fully-versed with some of the issues.
We've tried to reproduce the above using a DVI -> VGA adapter and have thus far found bupkis. We're not sure if this works with DVI -> HDMI either, but we do know it works with DisplayPort -> HDMI. Check it out for yourself and let us know your results.
