Monitor with wrong resolution after 10.5.7 update!!!! PLEASE HELP!!!

My mac mini is not working through the HDMI.
Still stuck to the jurassic RGB cable because of apple`s mess up.
I am hooking to a LG 40 inch LCD TV resolution 1366 x 768

Not good for me guys.

All's well that ends well, I suppose. I installed 10.5.8 and originally thought that the upgrade failed. During the install process, the machine restarted 3 times. After the third restart, I got nothing but a light blue screen. I waited 20 minutes and nothing happened, so I did a hard restart and everything came up ok. 1360 x 768 @ 46 Hertz with overscan enabled. My sympathies to those of you who continue to have problems.

New OSX release solved the problem for me too. I was again able to select 1920x1200 resolution for my Hyundai W240Dv2 monitor (connected through DVI).

Situation back to normal... a few months late though.
Also it means I'm be more confident that Snow Leopard should manage my monitor correctly when it'll be released.

mac mini c2d with HP w2207h
1680x1050 over HDMI works again after 10.5.8 update.

(I needed to reset the monitor to factory settings and delete the overrides (system/libraries/displays/overrides) to get it to work. Probably messed things up when I tried to get 10.5.7 to work with 1680x1050 over HDMI.)

Thank you Apple.

Hmm, what are overrides and which ones can I delete?

I can confirm that 10.5.8 has fixed the issue for me. Yay.

1280 x 720 still does not work. The apple desktop still over scans my plasma as per 10.5.7

my mac mini is fixed! thank god. update went on no problem.

My mini still doesn't have 1368x768 with dvi-hdmi or VGA on my JVC LT32... Not a happy switcher!!!

The source code being now available, I confirm that they changed at least one point. In fact, the whole HDMI 1.3a stuff is still there, but they now enable EDID resolutions again in case of HDMI.

Precisely, in 10.5.6, they were doing:
*Activation of EDID timings
*Activation of CVT Standard timings
*Activation of Established timings

In 10.5.7, they did:
if (monitor is not HDMI 1.3a compliant) then {
*Activation of EDID timings
*Activation of CVT Standard timings
*Activation of Established timings
}

In 10.5.8, they now do:
*Activation of EDID timings in all cases
if (monitor is not HDMI 1.3a compliant) then {
*Activation of CVT Standard timings
*Activation of Established timings
}

So it solves this problem for the vast majority of users, but it doesn't act as before in 10.5.6.
All that makes me think they are still searching the "good way" to do the stuff.

Maybe we can lobby congress for a "Cash for Clunkers" program for LCD's. Trade in your old, non-1.3a-compliant set for a new 1.4 compliant model.

BTW... thanks for all your work and research on this problem, Stephane.

Not that it matters much any longer, but I finally received a reply from the HDMI folks. I thought I'd post it just in case someone was interested.

Dear Bill,

There were no changes to the HDMI spec that would affect such cases.

Any changes made were specific to Apple products and not something caused by a spec change.

Jeff

Still not fixed for me... sigh...

It's strange - since my Denon is supposed to be 1.3a compliant.
But I don't know how HDMI works.

Does the receiver terminate the connection? Does the EDID come from the receiver? Or is it passed through from the connected sink / monitor?
I think it comes from the receiver, since my mac reports the monitor type as a Denon-AVR.

Arriving late to this, with only a question to add.

I have a new Mac Mini attached via a DVI-HDMI cable to my Sony Bravia KDL-40S5500.

I have the choice of 1920x1080 60Hz NTSC as one of the potential display settings, with or without overscan. Without overscan I get black bars all around the picture and with overscan I lose the edges of the screen.

The display has 1920x1080 pixels and the manual says it can take 1920x1080 via the PC connection (not the HDMI)
The HDMI "PC input" has a max resolution of 1280x1024

I had a go with SwitchResX, by examining the EDID text file, but that seemed to replicate the existing display settings rather than giving me a new option.

Should I be able to crack this by messing around with SwitchResX settings, as here

Or should I cave in and use a VGA cable?

Thanks,

John
