I have a MacBook Pro with the latest operating system, trying to configure a Gateway flat monitor with vga.
Thanks
Apple menu -> System Preferences -> Displays.
System Preferences can also be found in the Hard drive -> Applications folder.
Resetting the PRAM can help bring displays back to factory settings if you can't find what you need:

I get a black screen on the camera app on my iPod touch? Is there a solution? Resetting only helped for a few days, the problem comes back.
Camera works, with the side buttons it takes pictures.
Although I'm not able to see on the screen.
MikeFirst try a restore from backup
If problem still occurs try a restore to factory defaults/new Pod.
If still occurs likely a hardware problem and an appoitment at the Genius Bar of an Apple store is in order. -

Recently I've been getting this weird problem where my macbook air will show a black screen with only the cursor visible that I can move around but nothing else can be done to get to the desktop. The only way is to close the lid and wait for around 10 or more seconds and then open the lid again to bring the laptop back from sleep and hope that the laptop goes to the lock screen and then to the desktop. This works often but sometimes the only solution seems to be to restart the laptop. This also happens when I tilt the lid to the point where it is almost closed and when I tilt it back the screen presents the above state. Theis has been happening often now and it is almost impossible for the above not to happen atleast 2 to 3 times a day. iThis is a relatively new problem that has been occuring since the past two weeks or so and never happened to me on my Macbook Pro 15 2011. My current system is a Macbook Air 11" 2013 Haswell 1.3 Ghz 4GB RAM 256 GB SSD. Now I dont want to have to send in my laptop if I dont have to if there is a way I can solve this myself. Anybody else have this problem?
Hello tseten,
I would be concerned too if my MacBook Air was not waking from sleep appropriately. For an issue like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Resetting NVRAM / PRAM
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 second time.
Release the keys.

There is also a search box that appears in the middle of the black screen. Not a regular search, but its return gave "suggestions" instead. The left bottom of the screen has like a double exposure of the aforementioned, overlapping words. If I hit the Home button I will get the Firefox search screen. But I can't pin even a normal search screen. I have no idea why this started to happen, but I think it began with the latest update to Firefox I did a few days ago. How can I get back to what used to open up with a new tab?
Thank you for you help.You can use the SearchReset extension to reset some preferences to the default values.
*https://addons.mozilla.org/firefox/addon/searchreset/
Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window

The pdf engine in Safari has stopped working. I can no longer view pdf files in Safari. I simply get a black window when pdf files are downloaded
Hi..
Go to /Library/Internet Plug-Ins
Move the AdobePDF browser plugin to the Trash.
Try Safari.
If you have problems locating the plugin...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:

I am running latest versions of firefox, flash and using windows 7
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Try to disable the hardware acceleration in the Flash Player.

Hi,
When I open firefox (note: I got firefox version 28.0 and Karspersky security 2014) I get a black screen covering the whole firefox window and it looks more lika a big command prompt window, in firefox. What is it?
Regards
JeanHuh, that's a new one...
Can you try Firefox in [[Safe Mode | Safe Mode]] to see if the problem goes away. I'm thinking it's an extension.
*Run ''firefox.exe -safe-mode'' in the search bar on the Start Menu. (Make sure Firefox is closed)
Have you added any new extensions recently around the time this started happening? Your system details shows the following:
*Adobe Acrobat - Create PDF 1.2 ([email protected])
*Anti-Banner 14.0.0.4917 ([email protected])
*Dangerous Websites Blocker 14.0.0.4917 ([email protected])
*Kaspersky URL Advisor 14.0.0.4917 ([email protected])
