external hdmi 1080i vs 1080p

1) try as I might, the MBA only gives choices up to 1920x1080 (interlaced) and does not give an option for 1080p on an external monitor.

2) is there a published specification for the MBA which specifically states that 1080p is NOT available? Everything I have found simply states "1920x1080" without specifying interlace/non-interlace.

thanks for any pointers.

Macbook Air, Mac OS X (10.5.4)

It should be able to run at 1080p. What are you hooking it up to that it only gives 1080i? You might try this trick; in Displays preferences check the box that says, "Show displays in menu bar". Then, under the resulting icon that shows up in the menu bar, drop down the menu and set "Number of Recent Item" to 10. Then restart. Sometimes, when you go back up the the menu bar icon and drop down the menu, there are two 1080 resolutions that show up and one of them is 1080p. Good luck.

Thanks for the suggestion. I just tried it with two different external monitors with the same results: (1) the pull down menu does have two separate 1920x1080 choices (as you noted) neither is designated 1080i or 1080p -- when one is selected, the monitor reports 1080i, when the other is selected the monitor reports 1080p !

next question(s): (1) why is the "prefs" UI broken? (2) why does the drop down menu fail to distinguish between 1080i and 1080p ?

Those are two really good questions. Something does seem broken in the GUI, but it's not clear what. I'm glad the work-around did the trick for you.
