Screen Resolution Changes on its Own

Can someone explain to me, why when I turned on my computer earlier today, the resolution was changed? I was using my MacBook just one hour ago, when everything appeared fine. I did not adjust Systems Preferences, but nevertheless, upon re-booting, it "decided" to change the appearance of the screen. I have since readjusted things, but am curious how this took place, and if it means anything ominous.
Thank you,
John

Sometimes a power management scheme will kick in on a laptop and change the monitor brightness. When editing you should always work with external power connected and all settings set at Never for that state.
And, if you're serious, get a good monitor!

Screen brightness changes on its own

My laptop screen brightened all of a sudden on its own, 1/3 - 1/2 EV. I was editing a photo in PSCS3 when this occurred, the photo was from Lightroom. The brightness change effected everything, not just PS. For the past several days I've been editing photos in LR & thought I had the tone adjusted pretty good on all the photos. Today when I looked at the photos again, I felt like I needed to brighten then up some. After making exposure/brightness/tonecurve adj. to the photos today, I needed to do editing in PS, and as I was editing, the screen made a brightness change. I recalibrated the monitor & the brightness stayed the same. How could the previous monitor profile be turned off & all of a sudden turn itself back on. Windows Vista on Sony Vaio laptop (yeah I know I need something besides a laptop screen to edit photos). This probably has nothing to do with PS but I thought I would try on this forum as it's usually very helpful. Perhaps you can suggest another forum that might help. Thanks!

Resolution changing on its own

Hello,
I have a 2003 20" Cinema clear acrylic display hooked up to my MacPro and it's been working fine for the last year. Over the last couple of weeks the display resolution has been changing to a smaller resolution by itself. I'll be away from the computer and can come back to the screen resolution different from how I left it.
The change can last for a few days, then it will change back to the proper resolution (1600 x 1000). That can last for a few days, then change back again...!
It's very frustrating as I then need to scroll up and down, side to side to view the entire screen.
I've tried changing resolutions, colour calibrating, resetting the PRAM, loaded SwitchResX Preference pane software, run hardware diagnostics but nothing works.
Also - when the screen goes to sleep, it will come back momentarily in the correct resolution, but then change right away to the incorrect one.
Any suggestions where I can start diagnosing?
Thanks in advance,
Mitch

My Macbook changes resolution also. I have the 13.3" screen. Can't really pinpoint it down, but seems like when I use the touchpad, is when it will change. And it is very annoying because I can't get anything done, because it does it all the time. I've downloaded and installed every update available, and still no good. It does the same thing when I am in WIndows. Anybody know what is causing this and how to fix it?

Screen resolution changes every time I open I-Tunes

The screen resolution changes when I open I-Tunes. I have to go into control panel every-time to adjust the resolution to make the print and screen layout small enough so its entirety is captured which then allows me to use I-Tunes. Otherwise the graphics are too large to be captured on the screen making the program unusable.

T420 Screen Resolution Change Issue

My T420 laptop is capable of 1600 X 900 screen resolution. After changing the resolution temporarily to 1024 X 768,
I tried to change it back a couple of hours later to 1600 X 900. However, now I do not even see 1600 X 900 as an option.
The highest option is its' current setting of 1024 X 768. Can someone tell me how I can get the 1600 X 900 resolution to show up
again as an option so I can change the screen resolution back to its' factory setting? I do not know what could have happened
except for maybe a windows update took place before I attempted to change the screen resolution back. Any help
would be greatly appreciated.

hey Quinn,
welcome to the forums. could you check the graphic card version on your unit and compare it to the version available on http://support.lenovo.com .
is it the same or is the one on the support site ? If both of it is the same, uninstall the graphic driver from your unit and then download the driver from our support site.
do not install it yet, set your unit to diagnostic mode via msconfig first and then only install.

When I reboot computer the screen resolution changes automatically.

Hello anitagold:
Welcome to HP's forum. Thank you for visiting us how ever you are on the wrong forum. You own a business Touchsmart witch has a total different operating system then home user's does. This section is for home user Touchsmarts. This is where you need to post http://h30499.www3.hp.com/ You will receive a much accurate respounce I also think they have live chat assistance as well during business hours on line as well. Your software is also different then ours is so it would not do you any good for me to give you direction on how to adjust your screen resolution. Because your computer even though they look a like on the outside they are not alike inside. Thank you frrw.

Main "Play Control" volume changes on its own when I open and close WinDVD or Winfast

Main "Play Control" volume changes on its own when I open these programs, and when they're closed the main volume resets to where it was before the program was opened.
Surely I'm not the only one who has had this problem before.. I've had the problem with both Creative soundcards I've owned, before and after different drivers installations.
It can be very irritating and can potentially lead to damaged speakers if I'm not paying close attention to what my various volume knobs are set at before and after I open these programs.
I appreciate any and all input, thankyou.

Facebook screen resolution changes automatically everytime on Mozilla Firefox 4. Other websites opens fine.

I have recently updated to Firefox 4. I am having many problems with this version.
I am unable to use Facebook properly. The Facebook screen resolution changes every time automatically. The screen resolution gets very big.
When I open the FB site the resolution will be fine as soon I open another tab to check other website and roll back to the FB tab the screen resolution gets big and can't get back to normal view.
I have to close the FB tab and open a new tab to put the FB URL to use it. When I try to view other tabs and then open the FB tab the screen resolution is changed.
I have problem with only FB on Firefox 4, other websites are working fine.
I also tried opening FB on IE8 and Chrome. Their the site is opening normal. Have no issues with their browsers. I spotted it to be a problem with Firefox 4 and also the IDM (Internet Download Manager) doesn't work on the FF4 where it used to work on the earlier version of FF.
Do something about the IDM integration with FF4 to download FLV,MP4 videos from YouTube and other websites.
There is no "Go back to multiple pages" button in a FF4 tab. It only allows us to go back to the previous page. If I have open 10 pages in a single tab then I have to click the back button 10 TIMES to open the last (10th page) but in the previous FF3 there is a facility to view all the pages in a drop down which the current version of FF4 doesn't have :-( I am using Windows XP 2 Professional 32-bit and owner of the computer.
Please fix the issues asap else I have to move back to the earlier version or have to shift to some other browser :

Screen resolution changes after opening PDF in preview and is enlarged.

Screen resolution changes after opening PDF in Preview and is enlarged.

Do a backup.
Quit Preview.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Remove the following. You may not find them all.

Spontaneous screen resolution change

I am running OS X Maverick since a few days.
If I don't use my system, the screen "goes to sleep" after 10 min. (like I always had).
Since the OS X upgrade I have the problem that my screen resolution changes to 800 * 600 after when I "rewake" the screen (by pressing a key).
When I look in the system preferences, the screen resolution is set to "best for my screen"
I have to change it manually to the original setting (1280 * 960)
Error in the screendriver????

Restart GKrellm on screen resolution change in KDE

Hi all!
Any trusty GKrellm wizards still out there? Or KDE mastahs?
I much prefer GKrellm and dockapps for my system monitor needs and currently use the former as a panel in the top right corner on my KDE 4.5 desktop. It works great except for screen resolution changes where switching from larger to smaller resolutions and vice versa breaks the alignment to the right border of the screen.
My question is if there is a lean way, either through GKrellm, KDE or even bash/d-bus or similar to restart GKrellm (which is fast and good enough a solution for me) when I change resolution? Any ideas?
I wish KDE had as an option for "on resolution change, execute X". Come to think of it, I would like KDE to offer this option for power management state switches as well. Hmm, perhaps there should be a generalized "state-based" daemon for launching arbitrary external commands in KDE much like the tools available on Android phones these days, like Tasker, Locale and Setting Profiles...

No hints for how to do this? What about in Gnome?

Screen resolution changes on iphone 4s after downloading OS 6.

Screen resolution changes on iphone 4s after downloading OS 6. Can't see entire home screen. I must reboot to restore original resolution, but while zoomed I can't see the ok button. What is the fix?

No one here knows when the next iOS update will be released or what changes it will include until Apple releases it.
iOS 6.1.2 does not disable Wi-Fi, the vast majority of issues with iPhones that appear after an iOS update can be resolved with basic troubleshooting which is reset, restart, restore (first from backup then as new).
If that does not resolve, then the issue is hardware related and no amount of iOS updates or restores will ever get it functional again.

After using Image Capture and watching a video, the screen resolution changes

Hello,
Normally the colors of my screen are clear; The top ruler of each window is grey.
But after scanning a color document, the color is pale. As if someone changed the screen resolution.
Is this a common problem?
My former Macbook Pro died because of a problem with the video system, a default acknowledged by Apple that they didnt want to repair under warranty anymore.
Does this ring a bell?
Today, the colors quickly became normal again, but I'd like to make sure it ' s not going to become a serious problem.
Maybe this sounds kind of vague, well if anyone has something constructive to say about this, please do.
thanks

When you decided to not copy the files into the iPhoto Library Folder you took responsibility for File Management. iPhoto does not touch your file structure. Therefore, when you delete a photo from iPhoto you have to delete it from your file structure by hand.
This is not the case if you let iPhoto do the File Management.
There is no way to get iPhoto to find the pics you have deleted from it but which remain in your file structure. In the future, you could Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected. You can then delete it from there, and after delete it from iPhoto.
BTW, many people hold on to their own file structure because they feel that they will be unable to find a pic in the Finder, should they need it for uploading or emailing. There are three ways (at least) to get files from the iPhoto Window.
1. Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, this produces a copy.
3. Show File: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
Regards
TD
