SeBsZ Posted August 13, 2005 Share Posted August 13, 2005 Hello there, I am sure someone has asked this before but I searched the forums for "resolution" and just couldn't find anything... I have a laptop with an ATI mobility radeon 9600 w/ 128MB graphics card. I am trying to get osX to run at my widescreen resolution of 1280x768. Inside OSx I can only choose 1024x768 from the list. I tried running OSx with the boot option: "Graphics Mode"="1280x800" but it will still run at 1024x768. I also tried "Graphics Mode"="1280x800x32" and "Graphics Mode"="1280x800x32@85" but none actually change the resolution. Help is very much appreciated. THank you!

dogbert Posted August 14, 2005 Share Posted August 14, 2005 "Graphics Mode"="1280x800x32" <{POST_SNAPBACK}> that isn't a standard VESA resolution, so the VESA driver can't handle it and uses the standard resolution 1024x768. Link to comment Share on other sites More sharing options...

intradink Posted August 14, 2005 Share Posted August 14, 2005 But my widescreen can't support 1280x1024... :S <{POST_SNAPBACK}> Hi SebsZ, I'm having the same problem (in VMWare though - not native). I tried: - ?video at the boot prompt, which lists out the video modes supported. However 1280x800 wasn't on the list. I don't understand why this is. If I tried some of the resolutions listed (1152x864), then VMWare would boot into those resolutions correctly (but wouldn't allow me to go into full screen mode)... grrr. Any ideas anyone?

Thank you <{POST_SNAPBACK}> from xplodenet.com, once suitable, add to boot config file: edit /Library/Preferences/SystemConfiguration/com.apple.Boot.plist add: <key>Graphics Mode</key> <string>1280x1024x32</string> I tried this and it works, but my problem is that the refresh rate is at 87Hz, higher than what my lcd could display. I cant do the custom refresh rate as my video card is vesa 2.0 Any suggestions? Link to comment Share on other sites More sharing options...
DJP Posted August 18, 2005 Share Posted August 18, 2005 Does anybody have an idea how we can patch the stuff so ?video gives us at least 1280x800 also?

From what i heard, the 1280x800 isnt one of them. check it out nonetheless. Link to comment Share on other sites More sharing options...

rohde Posted August 23, 2005 Share Posted August 23, 2005 I read on another bbs that you can manually set the refresh rate as follows: instead of using: <key>Graphics Mode</key> <string>1280x1024x32</string> use this to set refresh rate to 100 hz: <key>Graphics Mode</key> <string>1280x1024x32@100</string> I haven't tried this yet, but others seem to have had success with it. <{POST_SNAPBACK}> Yes true. It works for some but not all setups. Some (including myself) has experienced when you add the refresh rate the machine just boots repeatedly after displaying some error. So now you're warned Link to comment Share on other sites More sharing options...

setec Posted August 23, 2005 Share Posted August 23, 2005 I have an ATI Radeon 9000 64MB on a gateway 450XL laptop. I could only get it to 1280x1024 because everything above that was a garbled screen. I deleted ATIRadeon8500.kext in \System\Library\Extensions and set 1400x1050x32 in my com.apple.Boot.plist rebooted bam - crisp 1400x1050 resolution.

cyrana Posted August 27, 2005 Share Posted August 27, 2005 Deleting the ati kexts lets me run at 1400x1040 (that is 4:3, not widescreen, though). And, most cards won't let you pick the refresh rate. I think that is a VESA 3.0 spec, which isn't so common (most of these cards are VESA 2.0). On top of it, no functional ATI drivers really exist yet on OS X X86.
