Ok, I have two identical machines which are both hooked up to 2 KVMs.
The main kvm is an 8 port with a 32 inch LG monitor connected to it.

On one machine the MAIN (Center) display reads:
LG TV
1920 x 1080
Rotation: Standard
main.tiff
This matches the second machine yea;

The other two monitors are connected to a 2 monitor 4 port kvm.

Hanns-G
Machine A
1050 X 1680
60 Hertz (dropdown at right)
Rotation 90 (dropdown at right)
(See screen shot A3 in second post.)

Machine B
600 X 800, 60 Hz (all in selection list)
Rotation 90(dropdown at right)
B3.tiff

VGA Display Samsung
Machine A
1152 X 870
75 Hz (Dropdown at right)

Machine B
1152 x 870, 75 Hz (all in selection list)
B.tiff

wtf is going on?
Why do I have Hertz in the dropdown on some machines and ", 60 Hz" appended in the selection list on others. Is this something I should bug report to Fuc(A)pple?

TIA,
Scott

PS Screen shots coming.

Re: Resolutions on 2 machines (should be identical but arnt wtf)

Other screen shots (why is 3 the max)?
A3.tiff

The other big question is why am I not seeing 1050 X 1680
on both machines, they're hooked up to the same monitor?
WTF?

Anyone have any ideas on where these dialogs get populated, and can I manually populate the list by manipulating a xml file or binary DSDT, WTF< WTF > WTF ?

TIA
Scott

There is nothing wrong with the Mac operating system. The reason you're seeing two different behaviors is that the connection types are not the same. When you see multiple frequencies being offered, then you're in analog mode (e.g. VGA). When you see only a fixed 60 Hz frequency displayed, then you're in digital mode (e.g DVI). In order to make things behave the same on both machines, you need to connect your monitors and/or KVMs to the video cards using the same connector type (DVI or VGA). It's possible that your KVMs are also honking things up but I'd check the connections first. Typically, DVI connectors are white while VGA connectors are blue. I'd start there.

p.s. I doubt you'll gain many friends here using derogatory names for Apple.

Ok I solved my problem. If I set all the kvm's to point to the mac before I boot it then it recognizes the monitors correctly. This is really strange that it needs the monitors to be connected at boot and can't seem to discover them correctly after boot.
This does seem like a bug in mac os to me!

Glad to hear you solved it. FYI, My old PowerMac G4 MDD behaves the same way -- the video card won't put out a signal if the DVI monitor is connected after the machine boots up. I'm neither a Windows or KVM user but I'm curious if Windows (or Linux for that matter) will detect displays in the manner you describe (i.e video display hot swapping).
