Projector changed my startup resolution

I had to hook up my macbook to a low resolution projector and it changed my screen resolution. I changed it back in system preferences but the gray screen with the gray apple is low resolution then it loads to the set resolution. it doesn't seem to effect any performance but it is annoying. and resetting the pram doesn't work.

Try to reset the NVRAM/PRAM http://support.apple.com/kb/HT1895 since the display settings are stored there.

How to change external display resolution WITHOUT clicking "CONFIRM"?

I have a somewhat unusual situation. My MacBook laptop is actually now a ModBook (a pen-tablet computer), and as such I no longer have a trackpad attached to it. All of my inputs are via the stylus, tapping directly on the built-in display.
This works perfectly fine, except when I need to give presentations on an LCD projector (which is quite often lately). I like to use the projector as an external monitor, so that I can run the Keynote presentation on it while using my laptop screen as the presenter's display, with the upcoming slide, etc. If the projector doesn't give me an ideal native display option (sometimes, the aspect ratio for the 3 or 4 resolutions available in the Displays drop-down in the menubar turn out to be stretched or squeezed), then I, naturally, have to open the Display System Preferences and try out different resolutions.
The problem is, since my stylus only interacts by clicking directly on the built-in-display, I have no way of moving the cursor over to the external display when the dialog box with the "Click here to confirm change/You have 15 seconds..." message appears. So I can never click it ... so I can never confirm the new settings.
The workarounds I've used so far are:
- Mirror displays (not ideal, as I need the presenter preview of the next slide)
- borrow a mouse from someone (usually from a Windows desktop, frankly) and plug that in to briefly mouse over and click the confirm button
I'd love to find a software workaround that allows me to NOT mirror displays and also doesn't require me to carry around a mouse all the time (my laptop bag is already overstuffed...).
Thanks.

How to change the display resolution of APEX ??APEX doesn't have a display resolution. "Display resolution" is an attribute of the device and user agent software used to view the APEX page.
What do you mean by "the display resolution of APEX"?
In other word, if an end user sees large elements on a pageWhat "large elements"?
then he/she zooms it outHow?
"Zooms" what—the entire page or a single "large element"?
How can I set a proper ZOOM for my app by default ...Meaning what?
And as usual, we're missing:

Is there a method in labviewto dynamically save and change the monitor resolution under program control?

Is there a method in labview to dynamically save and change the monitor resolution under program control? I have another application that runs on another monitor. I would like to change the monitor resoultion to 640x480 on program startup, and then restore the monitor resolution back to the user's settings on exit. Can this be done?

Have you already done this manually? I've seen Labview scale front panels very strangely when changing resolutions...

Is there a way to change the true resolution rather than scaling?

Hi,
I have searched through just about every single forum, website and search engine there is and haven't found anything. Perhaps I am phrasing my question wrong. I currently own a Macbook Pro 13.3'' Retina (Of Mid-2014 since I just bought it?) and I can't figure out how to change the resolution. The OS seems to default to 2560x1600 no matter what I set it to because I think all its changing is the scaling. Is there a way to do this? I used to own a Macbook Air 13.3'' which ran 1440x900 and I know that it was pixelated. On the same size display here...when I run the claimed "1440x900" its still ultra sharp which means its using scaling I assume. Any ideas how do I change the actual resolution, not just the scaling. The OSX settings currently seem to be just the equivalent of modifying the DPI like you can in Windows. I want to find out if there is a way to change the actual output resolution.

The MacBook Pro like all laptops has an LCD screen. Like all LCD screens the screen has a single physical resolution, in the case of your MacBook Pro Retina 13.3" it is 2560x1600 pixels. This is the number is dots the screen is physically made of.
In the old days when desktop computers used CRT (Cathode Ray Tube) displays which looked like TVs these sort of displays could display multiple resolutions in fact CRTs have no single fixed physical resolution. However LCDs which use totally different technology do only have a single 'real' resolution.
If your really interested in how a CRT can do different resolutions then the answer is that a CRT uses an electron beam to excite the phosphor display on the front of the display (to make it glow), it scans from left to right, moves down a line and then does the next line, and so on till it reaches the bottom and then goes back to the top. The speed (rate) at which it does this is known as the horizontal frequency and the vertical (refresh) frequency or rate. If the horizontal line is drawn specific time and that is divided in to 640 units, then it can be told to turn off and on 640 times per line, if the same line is drawn in the same time but the interval is divided in to 1024 then it can 'draw' 1024 horizontal pixels instead of 640 horizontal pixels. In actuality the display has no physical pixel you are merely lighting up small or larger areas on the screen and hence a CRT has no single fixed resolution.
In order for a computer using an LCD display to use a different apparent resolution it has to 'scale' the image to a different size, as a very simple example if we wanted to scale down to 1280x800 pixels which is exactly half 2560x1600 then the computer would use 2x2 (four) physical pixels to represent a single scaled pixel. Often however the chosen scaled resolution may not be an exact multiple like that example. Apple on the Retina display have provided some suggested scaled resolutions which work reasonably well these being 1680 by 1050, 1440 by 900, and 1024 by 640 pixels.
None of these will look as good as 2560x1600 because the screen physically is made up of 2560x1600 dots and no amount of cheating will change that.

I am unable to play a downloaded HD movie from iTunes. SD movies play OK. An error popped up saying something about the display not suitable for HD movies but now all I get is a blank window. I have tried changing the display resolution to no avail.

I have sownloaded an HD movie from iTunes store and when I attempted to play it on my Windows 7 PC a error message popped up saying something about the display not being compatible for HD movies. I have tried changing the display resolution several times but it didn't help. Now it just comes up with a blank screen when I attempt to play it. SD movies work fine. I have the latest version of iTunes installed.
Can anyone help me resolve this problem?

Apparently the display is required to be HDCP compatible to view HD movies in iTunes. My display isn't so this is my problem. I contacted Apple support and they have agreed to credit me for the HD movie and I have now downloaded the SD version.

How do I change the image resolution of a photo?

Hi..,
     I am the beginner in Photoshop.
     I want to change one image resolution from 72 dpi to 300 dpi.
     So, I search and got one pdf for change the resolution of the image. In that they mention, take the "Printscreen" of the image and paste in the photoshop and change the mode(Index - flatten) and change resolution via the "Image -> image size -> Resolution".
     Like that i did, it changed correctly.
     After that I Open one already saved image file in Photoshop and do that same steps but the resolution was not changed.
So, now how to change that saved image resolution to 300 dpi...??
Regards.,
VISWA

Viswa,
To find the current resolution of your image, follow these steps:
With your image open in Photoshop, Image > Image Size (Like you've already done earlier).
Check the resolution as shown above. If it doesn't show 300, enter 300, hit OK and 'Save' your image.
Open the file and check again. If it still shows 72, post back with more details of the type of file you're trying to open in Photoshop and if possible, a screenshot so we can help.

I just bought a new PC and I have re-installed my Adobe Creative Suite Standard on it. Software open fine. PROBLEM: The toolbars (menu stuff) appear extra-small, too small for me to read... I sent on the PC setting to try to change the display resolution.

I just bought a new PC and I have re-installed my Adobe Creative Suite Standard on it.
Software open fine. PROBLEM: The toolbars (menu stuff) appear extra-small, too small for me to read...
I went into the PC settings and tried to change the display resolution. This changes the size of all the icons (not only Adobe) but it does not solve the problem when I open an Adobe application (Photoshop or Illustrator)... The PC is run under Windows 8.1 and my display resolution is 3200x1800 (but again, when I change the settings for a smaller resolution, only the size of the icons is affected. Once I open the software, the problem is still there, extra-small toolbars...). Help!!!

Anything before CC is not high-DPI compatible. Feel free to continue to experiment with your system settings.

How do I change the printer resolution?

How do I change the printer resolution on my OSX 10.6.2 laptop?
I have an ubuntu print server and it seems to only work at all using the gutenprint drivers. On my ubuntu client I had to change the print resolution from "auto" to 600x600 to make it work just fine.
The best I can do is make the Mac print pages squished down to 1/4 size. I don't see the same resolution option on the Mac.
Mac OSX 10.6.2
Ubuntu Server 9.10
Printer: Canon S900
Cups driver: Canon S800 Gutenprint v5.2.3
Cups version 1.4.2 on the mac
Cups version 1.3.9 on Ubuntu Server
Macbook Pro Mac OS X (10.6.2)

I can't speak for the printer directly, but most functions to change resolution are in the dropdown menu at the bottom of the print dialog. It has a gray bar running through it separating the basic functions from the advanced settings.
If you don't see that, but do see a blue button with a black triangle pointing down, click on that. Then you'll be able to set the advanced settings.
Once you set up the printer the way you like, save it as a preset. If you want that as a default, see this [MacOSXHint|http://www.macosxhints.com/article.php?story=20100125135830153].

How do I change my startup settings?

When I turn my computer on, about a dozen programs start up automatically -- which means I have to spend at least a minute closing or minimizing each one. How do I change my startup settings so that the programs only open manually, when I need them?
Thanks!

First go into Users and Groups, under your account, and see what login items you have. Remove any that might be causing the problem.
Second, when you reboot or shut down, make sure that you don't have reopen windows checked - this is likley what's causing your problem.
Third, check the applications that are opening via the Dock and make sure that you don't have Open at Login selected.
Any one of these could cause applications to start when you reboot or start up.

Is there any way to change the screen resolution in Front Row?

Hi all,
I've got a Mac Mini plugged in to my TV, and I want to be able to change the screen resolution depending on the content I'm watching (as some content is in 4:3 aspect ratio, some is in 16:9, and I'd prefer to have the picture filling the screen completely). Unfortunately, the TV doesn't have a "stretch" mode for making an 4:3 picture fit a 16:9 aspect ratio. If I know what I want to watch in advance, I can set the resolution accordingly using system prefs on the mac, but if I'm just sitting back choosing what to watch with the Apple Remote, it's annoying to have to leave front row, walk over to the computer and change resolution once I've decided what to watch, open system prefs, change resolution, re-launch Front Row and find what I wanted to watch again.
So I was wondering if anyone had figured a way to allow the screen resolution to be switched from within the FrontRow UI. I've seen that people have written python based plug-ins such as PyeTV and Understudy that allow different types of content to be added to FrontRow, but I've not found any utility plug-ins such as what I'm looking for on the net (nor could I find SDK documentation on this API in the stuff that comes with XCode).
I guess the other approach might be quick keys: has anyone had any success hooking up quick keys macros alongside front row in response to apple remote events? (seems too few events to be able to choose from, but I've never tried it, so I won't assume!) Or how about is there a way to trigger an AppleScript from within Front Row? And, of course, I'm very open to any other ideas you might have!
Thanks very much in advance for any ideas on this.

If you've changed your startup options on mac to start in windows, how do you fix and go back to mac on startup?

Please help! Thank you so much!

The Apple drivers you install in Windows also puts a Startup Drive icon in the Task Bar. Choose that to change the startup disk back OS X.
