Macbook Pro won't correctly support a 1600x900 monitor

So....Here's the setup: On my desk, I have two identical HP S2031 monitors, one connected to my MB pro 13" and one connected to an older HP Pavillion laptop. The recommended resolution for this monitor is 1600x900, which the HP laptop supports just fine; great picture, VGA connector, no problems. However the MB only seems to support the 1280x720 resolution, which is somewhat more blurry. When the 1600x900 setting in my display settings is chosen, the image is horizontally compressed and "pillar boxed", as if a 16x9 image is being compressed into a 4x3 space. I've switched monitors and the problem remains. I am using a VGA cable to the monitor from the laptop with the standard apple VGA adaptor. I'm wondering if the adaptor may be at fault here.

and I have tried the original thunderbolt adaptor

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

Macbook pro 2012 not fully supporting samsung 4k monitor

hi
I bought the Samsung U28D590 monitor to use it with my Macbook Pro Retina mid 2012 model. though it connected comfortably, but the feel of the screen resolution was very poor. I checked it up with the setting, it showed me "best to fit U28D590 " and also showed 60 hrz. but somwhow, it looked like i was using a normal monitor, never felt like using a 4 k display.
Is something wrong. Need help.

MacBook Pro won't play .mov or .wmv files.

Since "upgrading" to Lion my MacBook Pro won't play .mov or .wmv files, all I get is a black screen and the audio. It's so frustrating!!
I've read many other posts all along the same lines and wherever possible I've tried to follow the advice which has been given but nothing works.    I've updated all the drivers I can and I've even reinstalled Lion, nothing makes a difference.
I'm not really looking for any more advice, all I want is someone from Apple to read these posts, realise there is problem and get working on a fix or update.
I had no problems when running Snow Leopard and it would seem, looking at everyone else's problems, that the common issue is Lion.   Seriously, this is one area where Lion is a backwards step.   It should just work (like most things from Apple), but it doesn't.
Personally I believe there is a problem with Lion but from what I've found out from speaking to friends with other Apple kit, this might be a random issue only affecting some people as some have said they've had no problems while others have had the same issues as me.    One guy reinstalled Lion and it resolved the issue for him, I've not been as lucky.
As I say, I'm not really looking for more advice, simply some sort of update from Apple to fix it.   PLEASE!!!

This is a peer-to-peer user forum. Perhaps you would see more action if you and others would file a formal "Bug" report with Apple QuickTime technical people rather than repeatedly reporting a possible problematic problem which may or may not affect others on a random basis. QUICKTIME PRODUCT FEEDBACK
Since you aren't seeking further advice here is what I have observed. Not being a regular WMV file user, I had to create my own sample file to test—a WMV 9 file containing WMV3 compressed video and WMA2 compressed audio. Since I normally use QT 7 as my primary media player, I also stored the WMV data in its partially decompressed form in an MOV file container to avoid pre-playback delays in "classic" player routines and also provide a secondary playback test of MOV wrapped content. These files play as follows using the Flip4Mac component/player support and uncoded URL uploads:
QT 7.6.6 "Open File" - both files play correctly.
QT 7.6.6 "Open URL" - both files play correctly.
QT X.1 "Open File" - WMV file plays correctly. MOV file plays video without audio.
QT X.1 "Open Location" - WMV file appears to open but plays with "black" screen and no audio. MOV file plays video without audio.
VLC "Open File" - WMV plays correctly. MOV file doesn't open,
VLC "Open URL" - WMV file plays correctly. MOV file appears to open but nothing plays.
MPEG Streamclip "Open File" - both files play correctly.
MPEG Streamclip "Open URL" - both files play correctly.
GarageBand - WMV file will not import but MOV file does.
iTunes - WMV file will not import. MOV file container is accepted but as soon as iTuness sees the compression formats, it aborts import.
Safari - WMV file URL auto-downloads and playes in the QT X.1 Player. The MOV file URL opens and plays in Safari.
As you can see from these results the files do play but are subject to many different constrints based on old/new video technology support, independent QT subsets and/or container trapping constraints. In short, individual user results will depend on presence/absence of component support, actual compression formats, file container, application being used, and how the application is being used. Unfortunately, most users here can't or won't provide the prerequisite information or a sample file for independent examination. This makes it next to impossible to give advice in these matters or categorize the specific nature of the problem.

Macbook pro won't boot, stuck on white apple screen

Noticed today, that my macbook pro won't boot . It gets to the white apple screen with the spinner under the apple logo. It stays like this for a long time without doing anything except spinning.
I've powered down and tried to boot up several times.
I have boot camp and windows on my mac and when the white screen appears, I can press Option to bring up which hard drive and the Windows partition will load without any problems.

Exacty what happens when you try to boot up from the disc that came with your computer? Are you holding down the c key? Have you tried holding down the "option key?" Are you able to run the Hardware Test - Intel-based Macs: Using Apple Hardware Test
Shut down your computer and disconnect all peripherals (keyboard & mouse if pertinent) from your computer. Now reboot.
If the Mac starts up normally, shut it down again and then plug in one of the peripherals (keyboard or mouse first) and start up your computer again. If it does so successfully repeat the process, adding one peripheral at a time until your Mac acts up. At that point, disconnect the last peripheral you added, reboot your Mac and search the peripheral vendor's website for an updated driver.
If no driver exists or the problem remain after installing the new driver, try a different cable or a different port on your Mac.
If none of the above works, again disconnect all peripherals from your Mac, hold down the "shift" key to start up in "Safe Boot" mode.
If the Mac starts up correctly, restart without pressing the "shift" key.
If your computer still does not start up properly, shut it down and restart it while holding down the Apple+Option-P-R keys; keep holding "all 4 keys" down until you hear the startup sound "twice."
If none of the above work Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select Disk Utility.
Select the disk or volume in the list of disks and volumes, and then click First Aid.
Click Repair Disk.
(If Disk Utility cannot repair, you will need a stronger utility (3rd party) - Diskwarrior or Techtool PRO)
Restart your computer when done.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.
Remove any 3rd party ram.
Reinstall Lion - This will install a "fresh" copy of Lion without archiving old system files but leaves the rest of your files in place.
If your computer is still under warranty or you have Apple Care, take full advantage of it by letting tech support deal with your problems. It's what you're paying them for.
Out of warranty - take the computer to an Apple store or an AASP. Whichever is more convenient for you.

My MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode

Hello, everyone. Since I updated to Yosemite, my MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode.
Does anyone know how to fix that?
Thanks in advance,
Arthur.

Hi, arthurpacifico.
Thank you for visiting Apple Support Communities.
Here are a couple troubleshooting steps that I would recommend trying to see if it corrects this issue.
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
Reset your computer’s PRAM
http://support.apple.com/kb/HT1379
If the issue persists, try the troubleshooting steps I have attached below.
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.Restart your computer.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

My MacBook Pro won't start. It's old, c 2008, any ideas?

My MacBook Pro won't start. It's old, c 2008. Have tried many suggestions on line: opt, cmnd, r,p, etc. Any suggestions?

Hey treasure hunter,
I found some help for when your computer won't turn on. Try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.MacBook Pro: How to remove or install memory
Reset the SMC.
If you are still unable to start up your computer after trying each of these steps, visit an Apple Store or Apple Authorized Service Provider (AASP) for further diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).
Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).

My MacBook Pro won't connect to the Internet, but my phone and PC will.

My MacBook Pro won't connect to the Internet. My iPhone has no problem doing so, and neither does my PC. I think it's something to do with my DNS, but I'm not sure. My network connections say that both my Ethernet or FireWire are failed. What's wrong with my MacBook? Is there a simple way to fix this?

Hello Rattisate,
Sorry to hear you are not able to connect to Wi-Fi on your MacBook Pro. I would be concerned about this too. You can find information on how to troubleshoot this in the following article:

MacBook Pro Won't Boot after Firmware Update

So I just upgraded to a MacBook Pro which came in the mail yesterday. I removed the Apple-installed HD and swapped it out for a bigger, faster HD. I installed OS X from scratch, imported everything from my Time Machine backup during the Setup Assistant, and then started installing updates. Everything was running swimmingly until the last updates.
What happened is when I rebooted my MacBook Pro and logged in after a series of updates, I got presented with both a Bluetooth update and a Firmware update at the same time. Both required a restart so I thought I would kill two birds with one stone. I installed the Bluetooth update, and then when it asked to reset I installed the Firmware update instead. However, the firmware update didn't behave as advertised because instead of shutting the MacBook Pro completely down, it restarted and then started installing the firmware update.
Ever since the firmware update (which I think installed correctly but don't know how to verify), I cannot boot my MacBook Pro. Using the OS X install DVD I can view my firmware version using System Profiler, and the number it is reporting is MBP53.00A.B03.
I have tried booting in verbose mode to try and get a feel for the problem, and it eventually hangs on an infinite loop saying something about not being able to find something on disk0s2.
I also thought I would fix the problem by doing an Archive and Install, but it quit at the very beginning of installing with the error "unknown error".
Also I thought I would format the disk with Disk Utility and then try installing again, but Disk Utility reports that it in unable to unmount the volume.
Any help you can provide would be greatly appreciated. Thanks!
-- Update --
Remember how I'm unable to unmount the drive? I force unmounted it and then used Disk Utility to repair the volume, but still no luck.
I think the key to the problem is this new HD I put in runs at 3 Gbps. I think I read somewhere that the new MacBook Pro's don't support that.
I think next I should try swapping out the new HD in my MacBook Pro with the one it originally came with. What do you think?

I, too, have a brand new MBP 15" that I put an Intel X25 in. At the 1.5 (Prior to Firmware Update) setting, it worked fine. I rant the Firmware Update, all looked fine, but the drive is no longer able to be seen.
Flash the PRAM, per other suggestions to no avail. Boot off of the DVD and disk utility nor Profiler sees the drive.
Replace the drive with the stock that came with the MBP (which I had never even used) and it works.
Put the Intel X25 into a Windows machine and it works fine. Reformatted it (in windows) and put it back into my MBP. Still not able to see it (from the Disk utility after booting off the DVD).
Intel's firmware for the drive says its up-to-date (new drive) and if I attempt to "re-run" the Mac Firmware Update, it says that the machine is already up-to-date.
Seems odd that it worked before an now it doesn't. Also seems odd that the X25 works in other machines. And that my MBP works just fine with the stock Hitachi 7200 320GB drive.
Ideas? Intel says to call Apple Support. Not sure what I can say to them.

Hi! My MacBook Pro won't start! HELP !!!

Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
Has anyone had this same problem?
All I get is white screen + grey Apple and spinning grey disk... it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
This MBP is from 2011, runs on OS X 10.6.8
I tried booting with OS X Snow Leopard CD, it didn't work! (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
When i run coomand on root# fsck -fy --> RESULT = my HD was checked and seems to be FINE!
Thanks

Please make a Genius Appointment and take it in for service.

MacBook Pro won't reboot. Get spinning circle even after hard drive replaced at Apple Store

MacBook Pro won't reboot. Have to reinstall OSX each time I shut down in order to get it to start up. What could be wrong? I had the hard drive replaced already.

You shouldn't be using the disc at all. I thought I had made that clear. Boot from your recovery partition and run Disc Utility. If you get the same result -- the internal drive can't be repaired -- then you should consider replacing it. No storage device can be trusted, in my opinion, after throwing an error like that. But whether you choose to replace it or erase it, you have to get the data out first.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from your recovery partition (10.7 or later), a local Time Machine backup volume (10.7.2 or later), or your installation disc (10.6.8 or earlier.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have a working Mac, and both it and the non-working Mac have FireWire ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Macbook Pro won't print the first page of any file in any application.

Problem: My Mid-2009 Macbook Pro won’t print the first page in Microsoft Word, Sibelius 6, or in Adobe Reader. My printer is an old Canon MP480 that’s worked for almost 2 years perfectly. As well, the “print to pdf” function results in the same error. However, if I open a new user account it all works fine. To change user accounts would be an extreme hassle though so, if possible, I would like to first remedy this one.
Recent changes: the motherboard of my computer was replaced about a week and a half ago. I printed a lot of stuff from Word two days ago and that worked fine but, already then the print to pdf function was cropping off the first page. At the time, though, I accredited the issue to the word documents being filled with pictures of sheet music that I was printing instead of text.
Things I have tried:
Updated Mac software
Repaired Disc Permissions in Disk Utility
Checked for new printer drivers/firmware
Reset the PRAM (http://support.apple.com/kb/ht1379.)

No but it's not a printer-related issue because the "Print to PDF" function also leaves out the first page.
