jumbochilli Posted October 18, 2009 Share Posted October 18, 2009 Hi all, I've recently converted my relatively old P.C to Mac and been very happy. However, this morning as I wake up and turn on the hack, I noticed that it's startup screen resolution being different. OS X runs as usual-resolution 1600X900-though, the startup screen has been changed to somewhat 1280X1024. How could this be happening, I can't remember doing anything suspicious yesterday other than downloading and watching movies Could anyone help me please? Thanks in advance.

Anyway, I hooked up the system with a DVI cable which had been connected with a VGA one. Voila! Now my system boots up with full screen Link to comment https://www.insanelymac.com/forum/topic/192696-startup-screen-resolution-solved/ Share on other sites More sharing options...

helob Posted October 18, 2009 Share Posted October 18, 2009 Add Graphics Mode=1600x900x32 to com.apple.boot.plist. This should correct the resolution.

jumbochilli Posted October 18, 2009 Author Share Posted October 18, 2009 Add Graphics Mode=1600x900x32 to com.apple.boot.plist.This should correct the resolution. Thanks, but I already have that in my "com.apple.boot.plist" in S/E. The system is running with 1600X900 resolution, but strange enough only "startup screen" appears to be different. Thanks anyway.

skyhskyh Posted October 18, 2009 Share Posted October 18, 2009 I am no expert, but I have figured this out in my many-many-attempts and experiments to get my SL working. please correct me if I am wrong tho. If your monitor is plugged using DVI, the bootloader screen and apple loading screen will not be your 1600x900 resolution. Your running OS will be, yes. If you use DVI-VGA connector to connect to your VGA plug to your monitor. You will get full screen resolution. Obviously you loose DVI-output graphics.

artofware Posted October 18, 2009 Share Posted October 18, 2009 I have this issue too. I just recently bought a new 24" inch LCD (Acer Widescreen). Now the start up screen does not appear to be a full screen. Before this Issue I was running my Apple Cinema HD. 19" and it shows up full screen. Hmm?

Well, my monitor is hooked up by "vga" to vga" so I guess that's not the case, besides I had been using with not a single problem regarding display since the very first day of SL installation up until the day before yesterday. It happened all of a sudden, I have no idea why and can not recall any activity that'd likely to cause this issue. To be precise, I want my hack to get back to what it was like a couple of days ago, but then there's no point, I want to know how to trouble shoot if this happens again. Thanks a lot for taking your time trying to help me. Really appreciated.

Well, considering there had not been a problem up until a couple of days ago, I assume it's not related to"com.apple.boot.plist", but then again I'm a noob. Please forgive my ignorance.

Beerkex'd Posted October 20, 2009 Share Posted October 20, 2009 Edit the plist in /Extra/Themes/themeyouareusing - you need to change it in two places. If you don't have a themes folder, download a chameleon binary release and copy it from there to your Extra folder. Visit the VoodooProjects forum and read the Chameleon FAQ and Documentation.

If you don't have a themes folder, download a chameleon binary release and copy it from there to your Extra folder. Visit the VoodooProjects forum and read the Chameleon FAQ and Documentation. I did try editing two parts - that define bootup resolution, one at the begining and another towards the end of "theme.plist" in E/T - , but nothing seems to be changed. Maybe it wasn't the part that to be changed? And now I wonder, with the same "com.apple.boot.plist" why there was not a problem then, but now, why? Now I'm going to dig in "chameleon FAQ". Thanks for the info. Cheers. Link to comment https://www.insanelymac.com/forum/topic/192696-startup-screen-resolution-solved/#findComment-1304387 Share on other sites More sharing options...
artofware Posted October 21, 2009 Share Posted October 21, 2009 I think this has to do with what version you are using. I'm currently using RC1 Chameleon and I just found out it doesn't support 1920x1080. ahhhh.

I'm currently using RC1 Chameleon and I just found out it doesn't support 1920x1080. ahhhh. I think not. Because I had no problem from the day one up until the day this {censored} happened, for about a month and a half. So, I assume that it's not up to what version of Chameleon you use, then again my monitor's max resolution is 1600X900. I still don't have a problem with resolution the system is running at, but startup screen. It's really annoying all mobo and apple logo appear with 1280X1024 while booting and when it finally booted, here comes full screen. Anyway thanks for the input. Cheers.

jumbochilli Posted October 23, 2009 Author Share Posted October 23, 2009 It's been disastrous last couple of days. While trying this and that in order to solve this startup - bios - screen resolution issue, I messed up the system somewhere and had to reinstall SL again. Even it's not my first installation, it wasn't easy.( I opened the box more than 10 times to reset CMOS, how about that!) However, because I believed the problem-startup resolution- would go away, I felt rather relaxed. I reformatted the HD and updated BIOS to be in the safe side, but after all these were done, BIOS screen remained unchanged-1280X1024-, not full screen. Now one thing I know for sure is that it was(is) NOT about "Chameleon boot-loader", "com.apple...." or the monitor. I still don't know what caused this tho. Anyway I went ahead with the installation and now I have fully functioning OS X with funny looking BIOS (startup) screen. Well, I guess I need some rest. Cheers. PS: I still need help for solving this prolonged issue, please.

jumbochilli Posted October 31, 2009 Author Share Posted October 31, 2009 This issue which bugged me for a while has been solved. I switched the cable from "VGA-VGA" to "DVI to DVI". Thanks.
