Display issue - My macbook pro 2011 detects my display but does not display an image
Hi, I am having a problem connecting my MacBook Pro (2011) to my HP 2511x display. I used the display all morning with my mbp connected and closed. When I came back, after the computer went to sleep, I cannot get any image on the display. The computer detects the display but no image appears.
I have tried-
Installing the latest firmware and software updates
restarting both the computer and monitor
trying all of the possible display arrangements and settings for resolution and refresh rates
Also I am connected using a minidisplay to DVI adaptor in the thunderbolt port.
Any and all suggestions appreciated.
thanks.
Hello Aminetti,
It sounds like your computer goes to sleep, and will not wake up, so you must manually restart your computer. I recommend the troubleshooting in the following article:
OS X: When your Mac doesn't sleep or wake
http://support.apple.com/kb/TS5357
Reset SMC
Reset NVRAM/PRAM
Test with external devices disconnected
Try Safe Mode
Try another user account
Thank you for using Apple Support Communities.
All the best,
Sterling

my macbook pro goes to sleep by it does not wake up afterwards. I have to restart it. I had recently to change the board in the attached Thunderbolt display, because I noticed that the same problem arose when the display was attached.
Now with the new board, it can't be the display's fault. I hope it is not macbook pro's main board fault. Maybe hasthe notebook board been damaged by the faulty display?
To bring my MacBook Pro to service will slow down my work. This is why I am posting this message, in the hope to be able to run a diagnostic test myself.
Thanks a lot, in advance.Hello Aminetti,

just purchased call of duty 4 on my macbook pro 10.6.8 4GB but will not launch or open. Any suggestions, please.
Installing the Mac OS X 10.6.8 Update Combo will reinstall the App Store for you. Restart your Mac after the combo is installed. It's ok to do this even though you are already running v10.6.8. Then try launching the app.
if that doesn't help, try contacting the developer of the app > http://support.aspyr.com/home -
Can I insert a memory card into my Macbook Pro? I tried, and it does not go in on its own, I don't want to force it and get it stuck!! Help!
Maybe the wrong port or the wrong kind of memory card? You didn't say what version/year of Macbook Pro you have. Below is a photo of the newest one.
Red oval = USB port. It is to the left of the headphone jack.
Blue oval = SDXC card port. Is your card an SDXC card?
What are your options for transferring data to the picture frame? The manual should say. -
Yosemite - MacBook Air 10.10 - "Notes" does not open - "Preview" opens, but does not display PDF's - "iCal" works in new strange ways, as if no one checked its operation - Everything worked very well until Upgrade to Yosemite ! - Happen to others?
Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

please help. just got my jabra halo, worked fine with my iphone4 but can't use it on my macbook pro. it always prompts " the devise does not have the necessary service
Found these instructions here:
https://discussions.apple.com/message/15388885#15388885
I found an answer that worked for me. I am using an iMac.
(1) Sign out of the iTunes store
(2) Open a NEW account with a new Apple ID
(3) Go through the sign up process and then go to the ACCOUNT INFORMATION page
(4) Go to RECOMENDATIONS & PING POSTING
(5) Turn on Genius there
Once the Genius updates, you can sign out and then sign in under your original Apple ID or the e-mail address you use for the iTunes store. All my store credit was there and now Genius worked.
Rather odd but I actually like the Genius at times except when it can't deal with some of my lesser known bands that I listen to.
Worked for me. -
Since the upgrade to FF3.6, I've had several annoying glitches.
1 Dclick desktop icon, FF loads into memory, but does not display. End task. Then Dclick the icon again. This time FF loads and displays normally.
2. After closing FF with Save & Quit, next time I open FF, error message : "Well this is embarrassing, can't recover tabs". Start new session. FF opens with last tab instead of default site.
3. On some sites I click icons and nothing happens. Sometimes other icons on same page will open, but most won't. Internet Explorer will open the same icons, so the Problem seems to be in FF.
Am I the only one with these nuisances? Any help will be appreciated.
== This happened ==
Every time Firefox opened
== after upgrade to FF 3.6Hello John.
You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author. -
A problem has just started with my IPAD Air after 3 months of use.
If I try to open Safari by tapping on the icon the screen briefly flashes white but does not display the page.
Similarly if I try to open Settings page, Mail page, Calendar or Clock the screen just briefly flashes but the Apps do not run.
Some of the Apps do work on tapping the icon e.g. Maps, iBooks, Appstore, iTunes, Newstand etc.
I do have some website links which display when the icon is tapped e.g. John Lewis but some links do not work.
I have ensured that the ipad is fully charged, powered it off an on again, and cleaned the screen with a lint free cloth but the
same problem keeps occurring.I saume you used a second display at one time, otherwise the Display settings wouldn't be treating your primary display as a secondary.
IF you open your System Preferences>Displays (-System Preferences) and click "Gather Windows" it should pull everything to the display on which you clicked it. -
I own the 4s and my BT Planttronics Pro works fine with calls but does not work to listen to music?
Any ideas on how to correct this?
Thanks-VitaleyesI don't know what they call it, but my plantronics voyager pro, and my wifes plantronics voyager pro+ will not let you hear music through the headset. My Blueant T1 does support it and plays the music through the deadset.

Apple TV powers up but does not display all of a sudden. Tried all of the advice on this page to no avail. Any ideas?
Try resetting the SMC and PRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
However, I suspect you zapped the Mini, maybe the lower voltage part since you siad the fan works.
The power surge could have went into HDMI and damaged the TV.
Make an appointment at the Genius Bar of an Apple store.

I just bought my cintiq 12wx and was wonderding if i can connect it to my macbook pro 2011 through the thurderbolt using a mini displayport to vga adaptor? Please help!
Yes, it should work with a mini-displayport to VGA adapter. Since a 12wx also can take DVI you could use a mini-displayport to DVI adapter instead. Why go analog when you can keep it in digital!
I guess the usb is for the pen. -
Hi there. I have a brand new MacBook Pro 2011 and I'm having some problems with my wireless connection. I have in the same room a Mac Mini, my Ipad , my Ipod, 3 PC's and all of them have a wireless connection. I notice that since my last MacOSX update I have some problems with my wireless connectivity in my Macmini. Now I'm having the same problem in my macbook pro. I have internet in all my other devices but no internet in my Mac Mini or Macbook. The Access point is 5 meters away from my devices. I put some repeater in the middle to repeat the signal but I'm getting the same beavior. Can someone help me on this? If I go to the network setting and renew my DHCP address I can access the internet but after 15 minutes I'm getting the same problem again.
The signal bar on the menubar is not always an accurate indicator of how strong the signal is. A more accurate measure is if the signal drops entirely and you are definitely in range of the airport base station. Also anywhere within 3 meters you may get signal degradation because of overlapping radio waves cancelling each other out. You also have the option to ask to speak to a customer relations person when you call AppleCare, and ask for an expedited repair, and have your airport card properly seated. Sometimes they can get loose, or the antenna can get loose inside, though normally this isn't a problem unless the machine has to be opened for some reason.

My MacBook Pro will connect to Wifi at one location (this is a secure location) but will not allow access to the internet. I will put in the password but will not display page. Other wifi capable devises do not have this issue but my Mac and my Iphone 4S will not work. I have tried restarting the router. All other wifi locations I have been to have not had this issue. Any suggestions? I am realtively new to Apple products (less than a year) so any advise is greatly appreciated.
The other devices that are working got on with the same password. It says it is connected. Just nothing works on the internet.
