Almas Khan Posted April 5, 2008 Share Posted April 5, 2008 So I understand that you cannot change the resolution of the grey apple boot screen because of the fact that VESA standards do not identify greater resolutions and graphical information does not get passed till after the EFI has loaded into the boot screen, but I just wanted to check if anyone has found a work around to this or knows of a fix for the future? Nothing serious here just looking for an authentic mac experience .

I'd really like to have the grey boot screen at 1680x1050. press f8 on boot and type in - "Graphics Mode"="1680x1050x32" Link to comment https://www.insanelymac.com/forum/topic/97560-changing-boot-screen-resolution-to-native-for-monitors/#findComment-696954 Share on other sites More sharing options...
Synaesthesia Posted April 5, 2008 Share Posted April 5, 2008 To make the change permanent, edit the file com.apple.boot.plist and add: <key>Graphics Mode</key> <string>1280×1024×32</string> How? Open terminal, type: sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist. Edit the file then press ctrl-x to exit, push enter twice to save.

Synaesthesia Posted April 5, 2008 Share Posted April 5, 2008 However remember this is just for the splash screen. For everything can change the refresh rate in System Preferences -> Displays. Sorry if you already know this.

Almas Khan Posted April 5, 2008 Author Share Posted April 5, 2008 Ya I tried the Graphics Mode"="1680x1050x32@60 as a kernel flag in the Boot.plist doesn't seem to accept that command and when I try to use the other form of getting this to work <key>Graphics Mode</key> <string>1280×1024×32</string> Changing the res with my monitors it just goes Black screen before the grey screen and restarts has anyone tried 1680X1050 before at boot screen?

Synaesthesia Posted April 6, 2008 Share Posted April 6, 2008 Sorry, but my example was of course for someone with a 1280x1024 resolution screen. For you the code in com.apple.Boot.plist must read, <key>Graphics Mode</key> <string>1680×1050×32</string> And you can change the refresh rate, just use <key>Graphics Mode</key> <string>1680×1050×32@85</string> or @60 if you want to use 60hz, etc. Link to comment https://www.insanelymac.com/forum/topic/97560-changing-boot-screen-resolution-to-native-for-monitors/#findComment-698047 Share on other sites More sharing options...

nocixel Posted April 6, 2008 Share Posted April 6, 2008 Leave off the refresh rate. Try: <key>Graphics Mode</key> <string>1024x768×32</string> VESA 2.0 doesn't support defining the refresh rate from what I remember. Anyways, I left off the refresh rate and it worked for me. -n Link to comment https://www.insanelymac.com/forum/topic/97560-changing-boot-screen-resolution-to-native-for-monitors/#findComment-698730 Share on other sites More sharing options...
Ianxxx Posted April 6, 2008 Share Posted April 6, 2008 the instruction is supported, if you are using a flat panel try <key>Graphics Mode</key> <string>1680×1050×32@59.9</string> Link to comment https://www.insanelymac.com/forum/topic/97560-changing-boot-screen-resolution-to-native-for-monitors/#findComment-698750 Share on other sites More sharing options...
Synaesthesia Posted April 6, 2008 Share Posted April 6, 2008 try<key>Graphics Mode</key> <string>1680×1050×32@59.9</string> My friend has a 1280x800 display on his acer hacktop and would dearly like to get the splash screen in that resolution.

Any hints like this for him? should work the same just use 1280x800 try without refresh rate, if no look then try and find what refresh rate either windows uses or acer suggests Link to comment https://www.insanelymac.com/forum/topic/97560-changing-boot-screen-resolution-to-native-for-monitors/#findComment-698962 Share on other sites More sharing options...
