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)

It could just be a bug in the way the mini is reporting the resolution being sent. This has been reported by others, even prior to 10.4.10. Does your TV also have something like an "Info" display where it can show what resolution it thinks it is receiving? If so, check and see if the TV thinks it is getting 1080p. If the TV reports 1080p, I would consider that a more reliable indicator than what the mini is reporting based on past postings.

Same problem here. Any luck? I also noted that if I choose some of the lower resolutions, the virtual resolution in use will be whatever I set it to, but the LCD-monitor will report 1080p.

Another issue for me is the picture is a bit off-center, biased to the left roughly 4cm, anyone recognise this?

The monitor works without tweaking with my PS3.

I just got the Magnavox 42MF437B and have tried connecting it to my Macbook. Mac OS X detects the monitor as 1920 x 1080 (interlaced). I had this issue briefly with my old Westinghouse LVM-37W3 but was able to get it to output into progressive scan by clicking on the monitor icon in the menu bar and selecting the other 1920x1080 option. This however, did not work with the Magnavox.

I have tried using the third party app SwitchResX and creating a custom 1920x1080 setting but it does not appear to change anything. Have you tried using this app?

I am connecting using a DVI-to-HDMI cable. The TV is reporting a 1080p signal. However, Mac OS X still only offers a 1920x1080 (interlaced) option in the Display Preferences and not the usual 1920x1080 resolution. Any ideas? Thanks.

I am also having this problem with a Sony SXRD 60" XBR2. The max resolution available in displays is 1920x1080 Interlaced, not the 1920x1080 Progressive that should be available. The TV reports receiving 1080i. I am connecting via an HDMI-DVI cable and have tried multiple cables to no avail. Someone from Apple - please, what is going on here???

I have exactly the same problem. I have a new Samsung LE40M8 Full-HD television which supports 1920 x 1080 progressive resolutions. When connecting the TV and mini mac for the first time the TV reported 1920 x 1080p but the mini mac ((Core 2 Duo, 120 GB, 1GB)) 1920 x 1080i. The picture was pretty good though. After a few days something went wrong and the display started flickering and the Mac OS Options window switched to another resolution automatically.

Now my LCD-TV shows a 1920 x 1080i and the mac 1920 x 1080i but the display jumps up and down and quality is terrible. Any ideas on how to fix this.

I'm having the same problem. Mac-mini with a the dvi to hdmi link to a Sharp Aquos. Aquos says 1080p, mac says 1080i. Picture quality is terrible. I haven't found a way to force 1080i out of hte Aquos, so I'm curious how that would look.

Although off topic, maybe someone has an answer to this. I recently tried to watch some 1080p trailers from Apple and Yahoo trailers in quicktime. I'm getting terrible frame rates, like 10 frames a second. Last time I watched 1080p trailers, last year I think, no problem at all. This problem I am having on all my macs. The mac-mini intel 1.6 ghz with 1 gig ram, as well as my G5 dual 2.5 with 6 gb of ram, and that there, is just... uncalled for. What gives here? Best of luck,

I installed an application called SwitchRes X on my Mac last week and succeeded in creating a new preference resolution setting of 1080p. I activated the setting with the programme and now the Mac OS display setting shows and addition option of 1080p.

So far it has worked well. I'm not sure if the quality of the HDMI-DVI cable affects the signal quality? In any case, I'm also switching to a Belkin HMDI-DVI cable as recommended by Apple.

OK I am going nuts with my problem and can't figure it out at all.
I have a brand new mini hooked up to a Sony KDL40W2000 LCD TV.
The TV is capable of 1080p but I can't get the mini to output it.

(a) When I select 1600x900 on display options the TV input info says that it is getting "1080p" but clearly it isn't (text is bigger and the amount of the screen being used is about 95% of its total area.
(b) When I select 1920x1080 (interlaced) on display options, it works sometimes, doesn't work other times, the text gets a bit smaller but overall screen area is identical to 1600x900 yet TV says "1080i".
(c) I am not given an option of full 1920x1080 (noninterlaced) on the mini display options.
(d) I have spent the last 2 hours with SwitchResX and while I can get into the tab showing all the list of resolutions (including 1080p) I simply cannot get the bloody thing to become active on my TV. Also I thought this control was meant to enhance your display settings menu item - it doesn't - it stays exactly the same listing the same few resolutions as before.

Total disaster. I bought the mini as an improvement over the Apple TV and it's just becoming a nightmare.
Anyone any suggestions?

Though I did get it to work. I honestly don't know how or why. Actually, I had a friend install SwitchRes X on my mini while I was at work. He said when he clicked on 1080p, it didn't work and the screen looked all ****** up. So I though the program didn't help none. When I got home I checked it out. I right clicked on my desktop, and the whole list came down. There were two 1080p's listed. One with an exclamation mark, one without. So I clicked the one without the exclamation mark and it worked. But when I checked my Mac OS system settings, my resolution setting was still listed as 1080i. Before installing SwitchRes X, when I was on this setting, I would get a terrible looking interlaced image. Now I don't, so Switch Res did do something right, I just don't know what or how technically. At any rate, it is possible to get 1080p out of the mini, it just won't do it out of the box. This is frustrating. I don't understand why the computer is crippled this way. When you run a Cinema HD display on these things, they run at resolutions higher than 1080p...

When I get home from work today, I'll take some screen grabs of my settings. Maybe they will help.
