Do we really need a StartupItem / rc.local for displayutil?

Once I have adjusted my resolution using displayutil, I did not need a StartupItem after reboot, the resolution remains. That's the command I used (the other command did not work for me):

kill `ps awx | grep [F]inder | awk '{print $1}'`; sleep 1; displayutil -r800x600 -b32

What is the correct resolution for 4:3 SD TV, connected by composite?

I thought it would be PAL resolution (768x576), but this did not work, as well as 720x576 did not work. The only working settings are 800x600 and 640x480. Which one should I choose? 640x480 zooms in, 800x600 zooms out. Before i used 576i from ATV menu, but this was the wrong aspect ratio. Any ideas? --Mcka 13:19, 1 December 2007 (CET)

More help needed

When using this command: sudo /sbin/kextload -v /System/Library/Extensions/TVComposite.kext

no errors are reported but still no colors?

Any suggestions to what might be the problem?


I have tried using the application menu plugin method and the startupitem method but no luck I have tried to revert to factory setting v1.0 and starting the process all over too.

My tv is a pal tv.

Please add some trouble shooting tips to the page. --Rsn7777 01:29, 17 February 2008 (CET)

Solved: What I think is unclear from the manual page is that the TVComposite.kext should also be in the /users/frontrow folder

When following the manual page you move the TVComposite.kext as you should to the extensions folder. But there is no mention of the need to still have it also in the /users/frontrow folder.

displayutil does not work with ATV 2.0 anymore

If I try to use displayutil as described below, it ATV jumps to the menu to select a resolution, but the desired resultion is not there. Any ideas how to work around that? --Mcka 01:36, 18 February 2008 (CET)

Using "sudo" seems o help. --Mcka 01:38, 18 February 2008 (CET)

But it's away after reboot, so a StartupItem is needed. --Mcka 01:40, 18 February 2008 (CET)

That's the StartupItem Skript I use to make it work with ATV 2 again:

. /etc/rc.common

# change resolution 
kill `ps awx | grep [F]inder | awk '{print $1}'`
sleep 1
/System/Library/StartupItems/ATV_Composite/displayutil -r800x600 -b32

# load Composite kext
kextload /System/Library/StartupItems/ATV_Composite/TVComposite.kext

AS you can see, I've put TVComposite.kext and displayutil in the StartupItem directory, which makes it easier to restore for future updates.

But there are still strange things, changing resoltion does not work allways, and I don't see the startup intro anymore, and no Covers in the background of the "home screen"... If you know how to make this work again, let me know! --Mcka 04:42, 18 February 2008 (CET)
