Z60m display settings change

My display often reverts back to 1024X768 after hibernating, or screensaver on for a while, or lid closed after a while - even though I have set 1680X1050 as my default settings. Any other suggestions?

hey p26grinz,
without the external monitor and after setting the display, will the setting remain ?
have you tried uninstalling the graphic driver from your unit and then testing it with generic driver ?

Mac Mini display settings change after shutdown

After a shutdown, my Mac Mini's display settings will change on startup. This happens about 80% to 90% of the time.
Sometimes it may be due to playing a video game (Diablo 3) where the resolution in the game is slightly lower. The Mac Mini is set to 1080p, but in-game it is 1600x900. After playing a game, maybe half the time, when I go back to my desktop, the display looks different. However, even other times even when I wasn't playing a game, after a shutdown, the display settings will change.
The strange thing is that it isn't a change in resolution. The resolution stays the same. It is always 1080p after every shutdown. But something in the display changes. Curved shaped look more pixelized, like some kind of smoothing or antialiasing has been turned off. And bright things are too bright, dark things too dark, so images lose some detail. It is also a bit painful on the eyes. Everything looks less vivid and very dull.
Someone in an older post suggested changing refresh rates. Unfortunately, my Mac Mini doesn't show that option. It was also suggested to connect to a different monitor to possibly make the options appear. But I don't have another monitor.
My current solution is to reset NVRAM (command+option+P+R) on startup. It seems to reset the display settings and fixes the display problem 100% of the time. But the thing is, I have to now keep doing this almost everytime I start up my Mac, which is annoying.
Is there a way to ensure that the Mac Mini keeps my display settings and prevent it from losing them on startup? Or perhaps, a way to reset display settings from within the OS without having to shutdown again and reset NVRAM?

Display settings change after reboot

Thinkpad T400: 7417CTO
Windows XP Pro w/SP3
No docking station
I configure the extended desktop for external monitor and thinkpad LCD (both 1280 x768).
After I reboot for the first few seconds I see the display as pre-boot, then the displays are reconfigured for
single image at 800x600.
What is causing the display settings to change?
How do I prevent the display settings from changing?
Thank you,
Morris

Event on Display Settings Changed

Hi all
I im here in search of a small piece of information. Is there any event which is raised when the display settings are changed ? Or if there is a system wide notification which might be raised.
Please reply If you have any any information. Thanks A Lot in advance.

try resetting PRAM:
1. Shut down
2. Press the power button, and hold option+PR
3. Release the buttons after you hear the second 'dong'
4. Let your mac boot normally.
Good luck!

Odd desktop/display bug - how to reset user display settings?

Greetings all,
I woke up yesterday morning to a puzzling problem with my G5. I logged in and started working - and I needed to use the windows remote desktop client to shell into a machine at work. I noticed that the fonts looked sort of funny (randomly quished) so I logged out and then back in. Then I noticed that the problem was not in the RDC display, but in the display of my mac.
This is sort of hard to describe w/out actually seeing it, but here goes...
When I move my mouse across the desktop (or what ever apps I have open) and the mouse pointer moves across and invisible (yet perceptible) line on my screen real estate, my background, icons, parts of displayed apps and fonts "shift". This causes fonts in the affected are to get messed up and causes general display irritation. That's the best way I can describe it, it's sort of a "you have to see it" problem. I will also note that this problem did not arise after an update or a software install or weird crash. Just another day.
So first I tried messing with my display settings (change resolution, color profiles, setting the background to a solid color, turning off screen saver). Rebooting. Nothing. Still there.
So next I log into another account (the root account). Ah ha! No display problems! Tried creating another user-level account. No problems there either. Now we're getting somewhere - it's something that is effecting my main user account and not a problem with my monitor, video card or OS. That's good.
So since then I've tried:
- Grooming the disc that my home directory lives on with DiskWarrior.
- Repaired permissions.
- Deleting the contents of home/Library/Fonts in case it's some funky font rendering issue causing this.
- Deleted the contents of home/Library/Preferences/MicroSoft to get any of its potential badness out of my life.
- Scanning with FontDoctor looking for bad fonts.
- Deleted my desktop and finder plist files.
- General maintenance and cache cleaning (including the MS font cache) with Onyx.
- Booting to Safe Mode.
Nothing. The display problem persists afflicting that one user account. All other accounts (root, and a second user-level account residing on the same disc) are free of these problems even though they are all using the same display settings (monitor, resolution, color profiles, etc). And as already noted, this problem was not "brought on" by anything like an update, installation, preferences modification or fatal seeming crash of an app.
So, my question to all you good people is: what am I missing, what might be causing this and what else can be scrubbed from that account (cache, plist files, etc etc) that might be harboring and causing this display bug? I would really rather solve this problem than go through the very very arduous task of moving all of my stuff to another account (an option, but a very unattractive one).
I was not a mac user during the OS 9 days, but I remember my co-workers doing the "rebuilding the desktop" dance. I realize that this is no longer an issue, but I guess I'm looking for something like that. I need to remove any and everything from my user account that has anything to do with display and font rendering since it's obviously some setting lurking in that account causing the issue.
I googled and searched the forums for this yesterday but could not come up with anything like it and all of the maintenance tasks I tried have not worked.
Any ideas?
Cheers,
Monte
G5 Mac OS X (10.4.9)

Hi.
What kind of G5 do you have? An iMac or a PowerMac?
A PowerMac.
If you own a PowerMac, you'd better take a look (o
try with another one) at the DVI cable connecting the
display.
I did check my connections, but also, why would a faulty DVI cable only cause problems with a single user account and none of the others?
If you want to reset the display settings, start in
Safe Mode, and trash these files:
/Library/Preferences/com.apple.windowserver.plist
/Users/yourusername/Library/Preferences/ByHost/com.a
pple.windowserver.some_number.plist
If I were at home now, I would try and report back. But I'm not. I'll definitely give it a try as soon as I can. Thanks for the pointer!
Cheers,
M

6303i - display settings not saved!

Hello - I have updated my 6303i to the latest firmware from the nokia site.
Everything works fine but now any chance I make to my display settings (e.g. wallpaper) are not saved, i.e. the change is being populated until the next reboot of the device. Once I rebooted the device, all my display settings changes are lost and e.g. I am back with a device with no wallpaper.
Any idea what is going on?
thanks

The problem came back a while after installing 10.10.2.
However, it does seem to have been fixed by 10.10.3. Hooray.

Display settings switch upon screensaver launch

Hi,
I've been having some issues with my display settings changing every time my screensaver launches. Without fail, my color settings are switching from LCD to sRGB profile everytime my system comes out of screensaver.
My system is as follows:
ibook g4 14", panther 3.9, and standard os x screensaver
Why is this? Anyone got any ideas how to fix?
Thanks,
Dave Grant

G5 Freezes, display settings and videocard : A clue ?

Hello,
Before you begin to read this ( rather ) long post (sorry for that), i will summarize the final question :
Can there be a relationship between freezes and monitor settings in system preferences ? Are there solutions to improve these settings ? what can be done ?
*My experience* :
After last Tiger updates (9 and 10), my Finder (?) froze very often.
In April, for this reason, I made a Tiger "archive and install" installation.
Nothing really improved.
In July, after multiple freezes I uninstalled :
-ATI monitor utility,
-Optical Logitech mouse *LCC driver* (and come back to the cord original Apple mouse), and the
-APE folder "*Application Enhancer*" installed in System files, which I could not imagine to be there, since I had uninstalled "APE" from preference panes under Panther and +never reinstalled it+ after that. But EasyFind showed it to me and Pacifist indicated me that in the LCC driver package there was a "call" to APE installation (and in the last ATI monitor crash report I had seen this ape mentioned).
-dsl modem wifi card and come back to an ethernet connexion, and also
-reinstalled a *mac OS X 10.4.10 combo* update,
in spite of all these un-/installations, freezes were going on with a peak at 10 one day, leaving me convinced that something important in the G5 was totally dead.
One morning, on start, the screen was totally black and the monitor power green led was even off. (I checked warranty for the monitor : 3 years on site until ... November 2007, at least that could be saved.)
Before calling the shop where I had bought this *SyncMaster 213T* display, I wanted to be sure that nothing else was wrong. So, I did some test indicated on the Samsung paper manual (fortunately, there are still some...) i.e. : unplug the monitor from the computer and test it by itself ... I could see exactly the boxes that were indicated as "normal". So the monitor seemed to be "clean".
After I had uninstalled all other devices such as : USB 2 hub, Sony active speakers, and, on a friend's (knowing much more things than me on Macs) advice, made ( done ? sorry ! ) some vigourous PRAM reset I could restart with a "normal" screen.
The first thing I did, then, was to open the virtual monitor manual, in the trouble shooting session. Namely concerning compatibility between video cards and this monitor. There was something about frequencies unsupported by certain cards. I understood that the higher, the better. But to get the higher, I had to choose a lower Display resolution. In its native resolution (1600 x 1200), the Monitor pref pane proposed only 60 Hz; to get 75 Hz (the maximum frequency indicated in the pref pane) I had to downgrade the resolution from 1600 x 1200 to 1280 x 1024. So did I. After a last freeze, I restarted with PRAM reset. The screen was ok.
And several weeks after, in August, I realized that, since that time, I had encountered NO freeze at all. At that time, I was sure that the "vigorous" PRAM reset had made the wonder.
One day of August, I wanted to change my desktop image with a photo I had just taken. The photo size was wider than the display resolution and I could not see it entirely on the screen. So to get a total view of it, I changed the resolution size to the initial one (1600 x 1200 - freq. 60 Hz). And my photo was entire. Then, I wanted to read something in my newsreader ( Thoth , which I daily use). As a post window was too small to see the entire post and wishing to avoid scrolling, I dragged, as usual, the left lower side to resize this window and I saw the black border line figuring the new window ... but nothing else happened. The window did not resize and suddenly I realized that I was again in a freeze story. :-/
The Apple mouse cursor was moving freely but nothing else happened. And no click was efficient in the display view (but I could hear - as before - its reactive noise inside the G5).
I decided to wait a bit and dit it for about 20 minutes. Nothing went better and I had to shutdown and restart again, tried a "*fsck -s*" but there also, after a beginning of the process, monitor froze. Then, I decided to restart (with alt ) on a "safe" 2nd internal boot disk with a "clean installed" Tiger, which I keep for this kind of problems and from there repaired authorizations and checked the other disk (which appeared to be ok).
Then I restarted normally on my "working" session. Opened iTunes, but as soon as I wanted to click on Mail in the dock : re-freeze.
This time, when I restarted after shutdown (since the "force to quit" was unavailable), the first thing I did was to re-change the Monitor resolution and frequency (to 1280 x 1024 and 75 Hz). And from this time, mid-august, I had only one freeze, which occurred when I wanted to look at a genuine Apple screensaver (but for this, there are about two years that I had to abandon to look at them or at iTunes animations, that I miss ... snif) I just wanted to check if- now -with this display settings change, things were better, but no.
My display is a digital Samsung SyncMaster 213T (21") plugged on the DVI ATI card port.
Many thanks to those who have had the patience to read this and my apologize to those who have the feeling they have lost their time (and also for my approximative English).
*Thank you !*
PS : Since yesterday my SuperDrive, a Pioneer 106 D, (replaced one year ago by Applecare), seems to be definitely dead : a DVD appears like a text generic document in DiskUtility and does even not appear on the desktop although the DVD player opens, but on a "visualisation" window only (the name of the DVD, a video commercial one, which I could look at last week, did not appear in the window header but did in DiskUtility). And just before, another DVD made an horrible noise in the superdrive but nothing mounts on the desk, DVD player opened but I quickly removed the DVD because of the persistent noise (so I didn't open DiscUtility to see what happened). (Problems with this superdrive date from long).
Can there be a link between this last problem and others above ?

Hello! There are a couple of things you can do. One would be to run the Apple Hardware test to see if it comes back with anything. It's probably on one of the install discs if it's not on a separate disk. Second you can open the console (apps>utilities>console) and see if it's throwing a crash log that might help. The monitor and video card resolution could very well be causing the problem which would seem to indicate since a PRAM reset would clear the resolution settings. I think you'll have to find the resolution that works and stick with it. Tom
Hello!
For the AHT unfortunately impossible now with a dead Superdrive ... I had done it quite recently (one month) and all appeared to be ok. I'm thinking of buying an external one but don't know if it could help for this i.e: if an install DVD will run on an external drive.
for the console: I don't well understand your "throwing" a crash log ... Is it "deleting" that you mean? Then which one?
Just after writing this post, I read an interesting article by a developer about Tiger and resolution (an hidden feature) which I thought could be in relationship with my problem (I'm not a developer myself but to help localizing somme apps I had to install the DTools). Also saw in a forum a similar problem concerning a "younger" type of G5 monoproc 1.8, and an ATI RADEON card (younger too) and this resolution 1600 x 1200. It seems that several people (all gamers) with this configuration was meeting the same trouble. Sky punishment ??
Well I think I will stick to pram reset then.
Thank you very much for you answer (and your patience !)

Monitor says VIDEO MODE NOT SUPPORTED after changing display settings

HELP! I am about to have a nervous breakdown with my mac mini! I hooked up the mac to my Philips LCD via DVI. No problem at all. But because the screen is only 15" I wanted to play around with the display settings a bit. So I changed the resolution from it's original 1204x768 to the one higher (not sure of numbers) and to my HORROR, I now can't get any picture at all - it says "VIDEO MODE NOT SUPPORTED". I have tried everything I can think of. I have rest the P-RAM, I have unplugged all cables, plugged the back in again, I bought the mac into work and hooked it up to my monitor and changed the resolution back to 1024x768 which is what it was on originally and that STILL didn't work. I can see the Apple logo and then it goes black and comes up with the error message. HELP! What am I doing wrong - I can't believe one click of a mouse button has rendered my display useless!!!

Welcome to Apple Discussions!
Try booting the mini without the display connected, and then, once the system is running, connect the display. This will often force the system to default to a low resolution, and then correctly detect the display when it is connected.
If that doesn't help, with the display connected, boot into safe mode (hold the shift key down when starting up) and once the system is running, change the resolution to 1024x768, and ensure the correct refresh rate is selected. Rebooting normally ought then to give you a good display.
If all else fails, boot into safe mode with the display connected, and then in the Finder's file menu, use the 'find' option to search for 'windowserver' (no quotes). You should get 2 or 3 results, including one with a string of alphanumeric characters. Move all of them to the trash and restart normally.

Monitor won't display after changing settings

I changed the settings on my Mac Pro and apparently they are not correct for that monitor. The display is blank and now I can't get anything to display in order to reset display settings.
How can I get it to display again?

Change display settings to show mac on tv

I bought the cables in order for me to hook my macbook pro up to my plasma tv through and hdmi cord and converter. The first few times I hooked it up I was able to drag the screen over to the tv and it worked perfect, now it is not working and I'm not sure why. I have tried adjusting the display settings to see if that was the case, but it doesn't make a difference. If anyone has any suggestions it'd be appreciated!

It's not there. In Mountain Lion, the Displays options have changed somewhat:
It only shows the external display option when a display is detected.

Will migration assistant change the default display settings on my new Mac?

I just set up a new iMac and used Migration Assistant to load from my Time Machine. But now the display looks muted and not as bright. Would Migration Assistant change the default display settings on my new Mac?

Migration Assistant may not be the cause. But you should reset the NVRAM and see it that fixes the issue.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the third time.
Release the keys.

Permanent Crash related to changing display settings while FCP is open.

Recently, the display settings (arrangement) on my two monitors started changing by itself while I was working in FCP 6.5. I'm using ancient monitors (Viewsonic MB90 and Mitsubishi Diamond Pro 920. I just don't have the money to upgrade right now). Tis was annoying but I dealt with the problem by creating two different windows layouts. Then things got worse (the only thing I had done was install 8 gigs of additional memory on top of the original 2). FCP started crashing and now I can't even open the application. It doesn't react.
Apple recently posted a not very informative acknowledgement of the problem with changing display settings while FCP is open, but it doesn't suggest solutions to my problem. It would be helpful to know a) what resolution and refresh rates are best for these old monitors and b)how to open FCP again. Your help is greatly appreciated.

THIS IS IT!
Disabling the nVidia deep colors for 3d applications solved the uber-annoying "flicker-screen-settings-and-disrupt/crash-other-programs" issue. I specifically only disabled deep colors for Premiere, not for all 3d applications I use, because none of them have caused the same problem as Premiere.
This display-screen setting issue probably occurred because I use a Dell u3011 monitor which displays Adobe RGB color gamut, not just sRGB.
However, now this brings up another question with disabling deep colors (effectively disabling the Adobe RGB use of the Dell monitor):
QUESTION: If I have CG-rendered frames that seem to be created in sRGB and Adobe RGB (in two different programs), what color space should I be mixing/editing them in?
I'm somewhat of a novice with the color spectrum/gamut issue. From what I understand, if I edit both CG images in sRGB, I'll be losing color data from the Adobe RGB-created CG image. If I edit both CG images in Adobe RGB, will I create minor banding effects on the sRGB image because it doesn't have the color range that I'm editing in? Perhaps my question is more relevant to AfterEffects compositing of the images rather than simply/only editing them in Premiere.
The end result is something like an architectural film/ flythrough.
Thanks,
-Matt

Need to change Display settings, either resolution or color

HI
Due to a faulty graphics driver I need to be able to change my display settings dynamically.
I know that I should use DLL calls to user32.dll, and I know that I should use the EnumDisplaySetting and ChangeDisplaySettings. But No matter what I try my LV 6.02 crashes.
I can not use G-Tool as I'm not allowed to buy it. and the shareware version dosn't include this functionality.
I have found the following links to be helpfull (but not enough):

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/devcons_7gz7.asp
Can anyone please give me a hint. I suspect this is due to a bad choice
of input/output datatypes.

I took a crack at making the code work from LabVIEW and failed. The devmode struct is way too complicated! I believe you would be best off writing code in VB or C that can change the resolutions then call that code from LabVIEW. You might even find example code to do this on the web.
