    This happened to me also, after installing 10.5.7 combo upgrade on a Macbook Pro with an LG 24" monitor attached (DVI). I suspect it has something to do with the HDMI connection making it "look" like a television. Sadly, 10.5.5 and earlier "just worked" -- wasn't that supposed to be Apple's forte?

    Thanks for the tip, Matt -- you saved my night. I used the "export" button to get the file containing the right numbers for 1920x1200 resolution and all is right with the world again. Cheers..

    Yep! Add me to the list!

    Mac Mini 2007, 2.0Ghz + Dell 22" Monitor.

    My native resolution is 1600 x 1050, which is no longer selectable...

    This is ridiculous! Apple have 6 products and yet they still dont bother to test all 6 of them before releasing an update!? How lazy is that!? I understand that a new model of the mini is out, but that doesn't mean you alienate your customers..

    Sure its a small issue, but this just shouldn't happen for a company that sells an operating system designed for even the biggest idiots!

    I'm new to using TM (just installed over the weekend).

    This OS X update has screwed me too (screen res).

    How do I 'revert' to 10.5.6 using TM? I only seem to be able to revert 'files'. I just want to go back to an entire system snapshot from just before I installed 10.5.7.

    Can this be done?

    I had similar problems and found that switching from HMDI / DVI to VGA cables plus adapters got the standard resolutions back.

    Go ahead and add one more! Mac Mini Core 2 Duo 1.83 GHz hooked up on a Philips LCD 32 inch screen with DVI-D - HDMI cable.

    Worked perfectly on 10.5.6 then after the update the resolution list got messed up, 1360x768 just vanished and pretty much every option left either looks like crap looks like mega crap.

    Hope they fix it soon. Real soon.

    Yep, same problem. Mac Mini 1.83 hooked up to a Samsung 37 inch LCD TV via DVI -> HDMI and I lost my native resolutions. Boo.

    you have to boot from the Leopard install disk to use Time Machine for a full restore. I don't recall exactly what the sequence is but a search of the online docs for TM should give you the correct procedure.

    Same problem Here. Have a Mac Mini Intel Core 2 Duo and a 28" Hanns.G HG281 Monitor using the HDMI-DVI cable. Upon the install, the resolution display was changed to 1920x1080, when it should be (was) 1920x1200

    Disable DDC in your monitor's OSD and reboot or unplug replug the monitor. You'll be fine.

    I have the exact same monitor btw, I love it!

    Same problem here on a LG L245WP 24"er on a HDMI/DVI cable. While others have reported that changing to VGA helped, frankly this is a no go on this system-I once left the HDMI DVI cable (that came with the monitor) on my parents tele and HAD to use VGA in consequence of having no other cable–and the visual quality of that connection was unbearable–bleak picture, contrast lost, no sharpness…

    Whatever, the reason for this problem seems to be that the display is being recognized as a TV, the system profiler says so under 10.5.7 (and doesn't under 10.5.6) and a forth settings tab appears in the system settings that allows for overscan adjustment–well, I wish it weren't so and I beg Apple to look into this asap… I NEED a solution for this, even if this includes pressing the alt-key in combination with some recognize button in case they intentionally built this in to stop people from loosing their displays on real tvs… the DVI/HDMI connection is the only way I can get an acceptable signal to my otherwise perfect screen…

    I really like the monitor as well. What is the DDC in the OSD? I assume that is something in the display options via the buttons on the right hand side of the screen?

    I have exactly the same problem after upgrading to 10.5.7. My monitor is LG L246WH with only VGA and HDMI inputs, connected to my Mini (Core duo 1,66, GMA950) with DVI-HDMI cable. And after upgrading my main resolution (1920x1200) is gone! I can only select 1920x1080, which looks like crap, and it doesn't even fill whole screen (there is a black space around the picture).
    And I absolutely HATE using analog cable for such high-res picture. It looks bad - washed colors, not really sharp...
    Please, Apple - have someone fix this (and not in 10.5.8 update, because I will kill myself before you put it out...).
