My MacBook Pro can't find the display brand and resolution

Hello everybody,
I have a MacBook Pro "Core i7" 2.7 13" Early 2011.
I use and external display Philips 220C1SW
Recently my mac won't recognize the Philips brand anymore and use instead a generic display resolution, which is wrong.
Does anybody had the same issue?
Looking forward your answers
Mat

Hello le-mat
Check out the article below for resolving issues when connecting to an external display. I would start with resetting the NVRAM and SMC as they will resolve most display resolution and power issues.

My MacBook Pro can't find the FireWire port

My MacBook Pro (OSX 10.6.8) can not find the FireWire port. Until now there hasn't been any problems using the FireWire, but now it just deny any knowledge of it, so to speak.
The audio device lights up when I connect it to the MBP (yes, I did connect it when in off-mode), so it seems to work in a way.
Does anyone recognize this problem and knows how to solve it?

Have you tried following through the trouble shooting tips in this knowledge base article on Firewire?

New MacBook Pro can't find the base station

I just bought a new MacBook Pro and AirPort Extreme Base Station. My house is wired for Ethernet so I plugged the Airport Exteme into one of the Ethernet outlets and did the set-up using my old iMac G5 over the network. (I had to download the latest software for the AirPort Extreme to the iMac before this would work right.) I finally got to the point where I got a green light on the Base Station, but when I search with the AirPort Utility on the MacBook Pro it can't find it, even when it is physically only 3 feet away. I then plugged the MacBook Pro into the AirPort Extreme with an Ethernet cable and it saw it - no problem. I then downloaded all the software updates to the MacBook Pro, restarted, unplugged the Ethernet and tried again. The AirPort Utility still can't find the Base Station. I am running 10.4.10 on both machines. I have 10.5, but don't plan un updating until I get this to work. I spent about half an hour listening to Muzak while trying to get to support and finally gave up. Any suggestions?

In another Mac OS X user account. Choose Log Out from the Apple menu and log into it. If you want to move them over, drag them to /Users/Shared/.

Macbook pro can't find the audio device

Lately I have been having trouble with the audio. The sound doesn't work on the Macbook, and it can't seem to find any devices!
I tried plugging in headphones, but nothing helped.
In the time leading up to this fault, the sound in the mini jack was very poor, and sounded really bad.
When I plug my TV to the computer, by HDMI, I works fine. Even with sound.
Any suggestions?
Oh, and I can't adjust the sound - it simply tells me that there is no device.

I've tried that, and I can't choose anything.
As I said, it can't find any devices. Tried to Reset SMC and PRAM - non helped

My macbook pro can't "find" my disc (?!)

I've just got the sims 3 island paradise and I've inserted the disc my macbook pro can't "find it". It asks me to insert the disc for me to be able to play when it's already in!? Why? Please help!!

Call AppleCare (1-1800-APL-CARE) and give then the serial number. They will send you a new copy of the two disks for shippingand handling of $16 each (I think $16 each).

Yes. If you have a non retina MBP, look at some options listed here:

After a year of no use and a fully discharged battery, my MacBook Pro refuses to accept the administrator name and the password. How can I reset these?

After a year of no use and a resulting fully discharged battery, the MacBook Pro refuses to recognize the administrator name and password (both). It has system OS X 10.6 which can not be upgraded without the information. How can I reset or reistall the administrator name and password?

Thanks to all who responded. You are all absolutely correct. However, this Ipad was a gift to my wife who was dying of cancer in the hospital and wanted some entertainment. So I started it out with her Apple ID. After she passed away I moved from Sacramento to Austin and eventually proceeded to get the Apple ID changed from my wife's to mine. Meanwhile when she was in the hospital I opened an Itunes account in my name to buy movies for her. That was the first mistake.
Then during the move to Austin I lost track of the IPAD and later found it and tried to use support but could not remember the proper ID. Later the folks at the Apple store helped me create a new and novel Apple ID that was unfortunately unlike any other.
The botom line is that I am stuck with three Apple IDs and three passwords. I am told by Apple there is nothing they can do about this as IDs cannot be changed or destroyed. I can quit using them or start a new account but when I try to do that the system keeps remembering too many things from the past and resists.
Even if I sold this Ipad and bought a new one, the system memory is still there.
I think the real problem is that destop and laptop computers are totally owned by an individual and that individual can control logins and passwords to his liking. IPADs and similar Apple products are different in that the corporation has built in their own intrusion detection schemes because of the relation to Itunes.
One thing I thought about is to open a new Itunes account pretendding to be a new customer with my regular Apple ID. Perhaps I could do the same with Apple Support.
Thanks for your comments.

My iSight is not working on my Macbook Pro. What are the possible problems and solutions?

My iSight is not working on my Macbook Pro. What are the possible problems and solutions?

Hello Douglas,
Thank you for the details of the issue you are experiencing with the built-in iSight camera on your MacBook Pro. I recommend the following steps for this issue:
Important: Follow these instructions in order. Test the camera between steps to see if the issue is resolved.
Built-in iSight cameras
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
If your built-in iSight camera is still not behaving correctly after trying all these steps, you may need to contact Apple or an Apple-Authorized Service Provider for service.

When you order a MBP you can have it delivered at any Apple retail store. When you get the e-mail that the MBP is ready to be picked up, you have options to enter in the rersponse if you or someone else will pick it up. You will have to fill in some required information that will identify that person to the store personnel.
I had my last MBP delivered to the local store, but I picked it up.
Ciao.

Dialog box says-"Bridge encountered a problem and is unable to read the cache. ... purge central cache" For one, I can't find the central cache and two, I've purged the cache in bridge. Shouldn't that help.

Our Bridge has been acting very strange. It keeps giving a dialog box of "Bridge encountered a problem and is unable to read the cache. ... purge central cache" For one, I can't find the central cache and two, I've purged the cache in bridge. Shouldn't that help? There's just all kinds of weird stuff going on. I suppose it does have something to do with the central cache, so maybe someone can tell me where to find it.
When I use the burn/dodge tool sometimes it drags and staggers and takes forever to complete whatever I'm burning/dodging. When I try to delete an image from the dock, it won't disappear but it won't display either.
Any help would be appreciated.

The Central Cache is the Bridge Cache.
It's referred as the Central Cache to differentiate it from the individual folder's cache or even the individual image cache.
