  I have a 2011 iMac with 12 GB of RAM running El Capitan and a 6s iPhone more - and 3 days ago just messages suddenly stopped sync on my iMac - I can send messages from both my iPhone and my iMac, but they no longer sync. So if I send an iMessage since my iMac and get an answer - I don't see any of the conversation on my iPhone and vice versa

• resolution 2560 x 1440 has suddenly stopped working. 1080 p now the max option available

  I have 2010 macbook pro (el capitan) and ASUS H257HU monitor that supports the resolution 2560 x 1440. Until yesterday, I was able to get the full resolution, but suddenly it has stopped working and the max resolution I could get was 1080 p.

  I tried to reset the smc and NVRAM, but that did not help.

  In safe mode, I followed the suggestion of apple and was able to get resolution of 2560. But it reboots the machine back to 1080 p. Hold down the option key and clicking on the option scale does not display any resolution above 1080 p.

  I've tried searching and following some recommendations, but no permits.

  Restart the computer and enter views sometimes give 2560 option, but clicking on it makes the screen turns blue and then it always comes back to 1080 p, with no options available in the dialog on the scale. The System Preferences dialog box hangs for a few seconds.

  Someone at - he fell on the same issue and found a solution. I don't know why he suddenly stops working, while still being able to work in safe mode but not in normal condition. I tried to remove the profiles as well.

  With bootcamp (win 7), the display works fine with 2560 x 1440.

  The connector I use is screen Mini DisplayPort.

  All proposals/solutions will be very well received.

  Hello there, moths.

  It seems that you are having problems to select the resolution you want on your external display from ASUS. Great job with the troubleshooting, you've done so far. The following Knowledge Base article offers strong information to look over and review, as well as links to some additional troubleshooting content:

  Get help with graphical problems on external displays connected to your Mac.

  Before you start

  You can solve many problems of display by updating the software on your Apple devices, cables and adapters. If you see an image on your screen, look for the software updates using the Mac App Store:

  1. Connect your external display and Apple video cables or cards that you use with it.
  2. In the Apple menu, click App Store.
  3. Click updates in the window of the App Store.
  4. Install OS X updates or firmware are listed.

  If you use a display, hub, extenders or adapter not made by Apple, check with the manufacturer for updates that might be available.

  If you try to connect a screen 4 K or Ultra HD TV with your Mac, make sure that your computer meets the requirements for the use of these external displays.

  If your firmware and software are up to date, or if you don't see the image on your screen, try the steps below for your specific problem.

  {...}

  Check the connections

  Check the connections on your Mac and external screens:

  • If you use an Apple laptop computer, try to connect the AC adapter.
  • Make sure that the power cable from the external display is connected correctly and that your display is enabled.
  • If you are using a Mac Pro (end of 2013), make sure that your screens are plugged into the right ports.
  • If you use a hub of display, Cabinet or "KVM", try to connect the video cable from your screen directly to your Mac instead.
  • Unplug the video cable where it plugs into your Mac, then reconnect to reinsert the connection.
  • If you are using a video card, unplug the video adapter on your Mac, then reconnect to reinsert the connection.
  • If you use multiple video cards to connect your screen (the cards are "chained"), testing connection of the screen by using a single adapter if possible. Some video cards may not be linked together. For example, a mini DisplayPort to DVI adapter may not be connected to an adapter DVI to HDMI.
  • If your screen has more than one video connection, see if you are using another connection on the display works. If possible, check if you use a different view or a different adapter works.
  • Try using another cable that you know to be in working condition. Check with the manufacturer of the screen to make sure that you use the cable they recommend.

  Detect your display

  If you use an external monitor, sleep and wake your Mac to check for connected screens:

  1. Press the power button on your computer to standby, or choose the Apple menu > sleep.
  2. Wait a few moments, and then press a key on your keyboard or click your mouse or trackpad to wake up your Mac.

  If you use more than one screen, and you can see the image on one of the screens, you can also use the preferences monitors to check the connected screens.
  

  Adjust video settings

  If there is no image on the screen, try adjusting the brightness or contrast of the screen. If there is still no picture or image appears torn, or scrambled, try selecting a different video resolution in system preferences. Adjust brightness

  • If you use an Apple Display Monitor, press the key to increase brightness your Apple keyboard. To adjust the brightness of a secondary screen, press Control + F2.
  • If you use a view that is not made by Apple, see the documentation that came with your monitor to see if it includes built-in controls to adjust the brightness or contrast.

  Change your display resolution

  1. In the Apple menu, choose System Preferences.
  2. Click the display icon.
  3. Click default for display. If you see more than one resolution listed, choose a resolution and refresh rate. If the display turns off when you change resolutions, press the ESC key to cancel the change.
     

  If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.

  If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

  Search for software third display

  If your monitor only works when your Mac is started in safe mode, and related to the software display is installed, check with the developer of the software for updates, or try to uninstall temporarily.

• My hp psc 1350 all-in-one has suddenly stopped working.

  My hp psc 1350 all-in-one has suddenly stopped working. I can no longer open the software by clicking on the icon in the dock.

  Sorry, but I thought that I had reported my all-in-one had started working again. Unfortunately, I can't say what went around, because I don't know.  I had only a small part of the way towards what we'll fix me it when he started to work again. I remember that there was a step that I have been unable to finish, and when I asked how to overcome this problem, it started working again. I don't even have the chance to follow the final instructions. I would rather know what was wrong and what are the fixed elements, but I'll have to settle for a working machine.

• Windows 7 screen saver has suddenly stopped working

  Recently, the screen saver on my laptop (Sony Vaio Z model VPCZ119GX with 6 GB of ram and a core i7 processor) has stopped working.  He has always worked in the past, but suddenly (as of mid-June 2010) stopped it.  None of the Windows 7 default screensavers work (for example to mystify, ribbons, etc.), nor fact Windows live Gallery screen saver.

  I am running Windows 7 Professional x 64.  If I go to preview, I can see the screen saver, but it does not start after a period of inactivity.  I reduced the timeout to 1 minute and I tried both require a password and no password and neither work.  I do not use a wireless mouse (I have read other posts that a mouse without a wire could cause this problem) and I have fixed via the USB port.  I went in the Manager of peripheral and done so that devices that have power management options have been disabled.  I checked my task manager and I don't notice anything out of the norm running in background.

  Here's the interesting part.  If I connect to the hidden administrator account screen saver works perfectly.  If I create a new user account screen saver still does not work.  Something prevents the screen saver works in the created user accounts, but works perfectly under the administrator account.  What could cause this problem?  How to solve this problem?

  Another interesting information.  The same problem exists on a friends Lenovo T400s under Windows 7 Ultimate.  His screen saver has worked a few days ago (week of June 21) but suddenly stopped as well.  A windows update may have caused this problem?

  Finally, I have not tested this, but it seems that hibernate/sleep has also stopped working.  Unfortunately, I sleep/hibernation activate after 4 or 5 hours and I can't say for sure 100% that I let the computer idle for this period of time, but I could have sworn that I have.

  I think screensaver and put into hibernation / sleep are all affected by the activities of intelligence and something is causing the machine to think that this is not idle.  But under the Admin account, it works very well.  I spent hours trying to understand this point, but without success.  I have even restored to the point of thinking older restoration that something could happen, but it does not solve the problem either.

  Help, please!

  briboynyc and dougfulcher

  I am so happy that I found this forum.  About 6 weeks ago, I lost my screen saver on our computer brand new with windows 7.  I was on the phone with HP in India twice and finally they decided to take back me to the factory restore thinking that it was because of our backup files in windows XP.  Repeat all. I backed up all my files, and then we started again from the beginning.  It's the same thing.  We packed up the computer and returned to the store, a new computer and started all over for the third time.  Last night is the same thing.  I was really frustrated and thought maybe it was a little problem with windows 7 so decided to get on the microsoft Web site to see if I could communicate with someone from Microsoft.  That's when I discovered this forum and started reading everything.  When I read the answer of dougfulcher, he mentioned magic jack running in the background.  We disconnected magic jack and that solved the problem immediately.  I am really grateful and only wish I had discovered it before that I lived all this computer return and restoration.  Everything seems to work very well.  I hope this helps someone else.

• My DVD/CD drive has suddenly stopped working under Windows 7

  Ive been using Windows 7 for about 6 months now with on any trouble until recently my DVD drive has suddenly stopped working. Windows detects the drive but when I double click on it in my computer it says please insert disc. I find the drive in Device Manager and windows recognises that there is an error that says:

  Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source. (Code 52)

  I tried to uninstall the drivers in Manager device and rebooted the computer to let auto windows find the driver and reinstall it but to start, I get a message that says:

  Device not installed driver software

  I know that the drive is fine because it works fine in Ubuntu Linux system he worked great in windows 7, so stopped. any help would be greatly appreciated. Thank you.

  Go to the Web site of the factory, download the driver appropriate for your device. Uninstall the driver that is currently installed and uninstall the device in Device Manager. Reboot... After you restart, you have 1 of 2 options depending on how the software is packed from the manufacturing. (A) put an end to the automatic Windows installation feature and use the downloaded software to take care of it for you... If that's how it is set up to operate or (b) wait for windows to auto-trouvez and try to install the device, and when he asked the pilots to open and extract files downloaded to any location you choose and point the installer of windows in this direction.

• Windows Media Center has suddenly stopped being able to see tuners. Error "could not find the tuner or all tuners are busy."

  Original title: Windows Media Center has suddenly stopped being able to see tuners.

  I am running Windows Media Center and have a 6 Ceton infinitv tuner connected to my network.  Since a few weeks things have worked very well.  Now suddenly after installing a faster wifi adapter, I get messages such as unable to find tuner or all tuners are busy... who don't feel like I can always go to the tuner by Explorer or chrome, by typing the address of it and it arises but also shows that it is set on the channels that I am no longer watching.  Any ideas on why WMC is suddenly acting when the only thing I did was install an a6200 netgear adapter, nothing has changed.

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
  ends. Remove and replace, do not just tight. For laptops, you can often clean power and

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
  manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

  ===============================

  Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
  Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
  do it right.

  Did you follow the Troubleshooting Guide for the reader who still does not work? There are

  Check with your Maker system and a device for the two possible firmware updates and the
  correct registry entries for your car.

  iBooks has suddenly stopped syncing between my 6s iPhone and iPad Mini.  Both are running iOS 9.3, and the sync was working well for several days after I updated the two devices.  The two options of synchronization (bookmarks/notes and collections) are enabled for both devices.  And no matter on which device I add a bookmark or a note. It will not synchronize with the other device.

  I rebooted both devices and enabled the synchronization options, and then on again, but I was not able to run.

  Any ideas as to what is happening?

  Thank you.
