Mini connected to 1080p HDTV

I have my mac mini conntected to a 1080p HDTV using a DVI to HDMI adapter. Prior to updating to 10.4.10, my system was exporting a beautiful 1080p (1920x1080 not interlaced) signal. After upgrading to 10.4.10, I can only get up to a 1080i (1920x1080 interlaced) resolution from my display settings. I have also tried a DVI to VGA cable with the same results.

What happened?

Thanks,
Jon

Mac Mini, Mac OS X (10.4.10)

More on the DVI on the mac mini.

At this link you can learn about the various types of DVI connectors. It appears that the Mac Mini is a DVI-I Dual link. (three rows of eight pins and four contracts around the blade). A DVI-D link is two sets of nine pins and a solitary flat blade.

It may be possible, haven't looked into it yet, that a DVI-I dual link can transition from a DVI-I male to a DVI-D single link female (if there is such a combination?) and then couple with a DVI-D to HDMI cable. Maybe that would trick the TV if the DVI-I to HDMI doesn't work right. ???? this is conjecture.

Where is apple tech? How can they simply ignore such an important bug?

I have a Samsung Full HD Plasma and I also have tons of problems for the display. I thought I could use the mac mini as a media center, now I think I can simply forget about it until I manage to resolve the video output problem.

HDMI (via DVI->HDMI cable: you dun need expensive one to get it work, belkin is just too overpriced):
I only have 1920x1080 (interlaced) in the list. Surprisingly, choosing 1600x900 gives the TV 1080p input! When can apple tech wake up and resolve this annoying issue? Or is it really a Samsung problem?

VGA(using bundled DVI->VGA dongle):
I can see the boot up screen and then after that it flicker some blueish thingy and went black totally!!!!

apple, both your VGA and DVI simply dun work on full HD plasma. When can we get these fixed?

Add me to the list - same problem. Mac Mini Core Duo connected DVI to a Westinghouse LVM-37w3. Used to have beautiful 1080p but after my OS upgrade the highest option in the displays panel is 1080i. Looks terrible - had to switch down to 1600x900. Would love to get my 1080p back!! I think it broke when I upgraded to 10.4.11. Currently running 10.5.1 and it's still broken.

thehut, can't say for sure if this will help or not, and I am not sure myself why it would work at all, but some people have reported success in restoring 1080p by doing the following:

Go into Displays preferences and check the box labeled "Show displays in menu bar"
Click on the resulting display icon in the menu bar to drop down its menu
Scroll to "Number of Recent Items" and select 5 (or 10?)

You may have to restart after this. Not sure. For some people this has caused two 1920 x 1080 resolutons to show up under the display icon in the menu bar. The second one is 1080p. Good luck.

I've just tried that with my Powerbook connected to my Hitachi TV via DVI->HDMI. I'm seeing two 1920x1080 options - one is PAL, the other NTSC. Both are interlaced and are reported (correctly) by the TV as 1080i, and I'm getting 1:1 pixel mapping with overscan turned on. The TV accepts 1080p at 50, 60 and 24Hz, so I should be able to get it to work. It looks as if I might have to use either SwitchResX or DisplayResX. Does anyone know which is best? I'm used to entering modeline parameters in the X11 config under Linux, so I'm quite happy with the technical stuff.
