Blinking Screen for MB Pro 17 inches

My configuration is
17 inches 2010 MB Pro with i7 chip
Non Glare screen
8 Gigs of RAM
Ever since I got it, I am observing sone annoying screen flashing. At some point I thought it was one of those visual alerts for handicapped, but after checking all my settings, I realize it is unrelated, it occurs randomly at any time during the day, and it is becoming very upsetting, as I work more and more time on this fast machine.
Everybody at Apple claims teh new Finder in Cocoa is so much more efective, and to me it has become customary to Force QUite the damned FInder over adn over on a daily basis, as the FInder freezes by my browsing files through folders.
Don't know if both situations are related, but wanted to make note of both in the same post.
Any tips will be appreciated.
Thanks
Jorge Parra

Only Apple has Retina replacement displays at this time as it's so new, still it's going to take time.
You'll have to get the data off it before it fails and use another machine in the meanwhile.

IMac (2010) as external screen for Macbook Pro (2012)

I've been googling this for a few hours now and have only walked into walls.
My 21,5" iMac only has a FireWire, Mini DisplayPort and several USB ports and has the newest up to date software but is from mid 2010.
My 13" Macbook Pro only has a FireWire, Thunderbolt and several USB ports and has the newest up to date software but is from mid 2012.
It would be very interesting and useful for me to be able to use my iMac as an extra screen for my Macbook Pro, as all I do is video editing, photo editing, video grading etc.
All help or suggestions is welcome! Thank you!

In addition to Niel's post, this article might help you out. What you're looking to do is called "Target Display Mode." I would make sure to especially check the "requirements" section to make sure that your model will work for this.

How do connect my sony bravia tv as a monitor screen for mac pro

How do I connect my Sony Bravia tv as a monitor for my MacBook Pro? I have an hdmi lead with an adapter to the computer and get a picture of factory setting cosmos with some of the folders of my desktop going off the side of the tv screen.

If you have the right cable, and have set the right input on your Sony, then you need to adjust one thing. Go to System Preferences>Displays>Set Mirroring. I think you've got it set to Extended desktop, which means the Sony is just a HUGE extension of your Mac OSX desktop.
That should fix your issue.

Use old Windows laptop as second screen for Macbook Pro

Hi all,
I've recently bought a Macbook Pro (mid 2012, 13", 2,5 GHz). So I'm not using my Acer laptop anymore, but I've came across a discussion of people who extended their Mac screen on a Windows laptop. I've tried multiple VNC apps, but no decent results (lots of lag, only mirroring my screen and so on). So my question is: how can I use my Acer to act like a second screen (I prefer a LAN connection instead over WiFi)
Thanks a lot!

Where can I buy a replacement screen for macbook pro

my screen broke and i want to know if i can have the screen replaced

If it a fairly new MBP the only place to get a screen is from Apple. If it is 3+ years old look on iFixit.com and or other Mac parts resellers. A google search will turn up a few.

Broken screen of MacBook Pro (Retina, 15-inch, Late 2013). Where I can find the part?

I have a broken screen for MacBook Pro (Retina, 15-inch, Late 2013) and I cannot find a replacement. Where I can find the screen? I will install myself. Thanks

Apple does not sell replacement parts, any you find will be third-party knockoffs. Take your Retina to an Apple store genius bar and have the techs tell you what needs to be done. New Retina screens are not cheap, they normally replace the entire lid as a unit.

External screen with macbook pro blinking

Hi everyone,
i've an external screen ACER connected via hdmi to my macbook pro run on Mac OS X Lion 10.7.3
The problem is the external screen blinks every 3 or 4 minutes, i get a dark screen for 1 or 2 secondes
i tried to change both the cable and the adaptater [hdmi] but it seems that the problem come from the OS configuration.
When i open the console.app to see which are the errors i got
IOSurface: buffer allocation size is zero
every 2 or 3 minutes, i need your help please

I own a mac mini that stays connected to the 52" LCD 120hz in my living room. The image is perfect, and fits just fine. I did a mini-display port to dvi and got a monster cable adapter for dvi to hdmi which too it to my tv. I did have to go into the tv and set the tv to overscan I think on the image to make it fit and you will have to adjust the resolution on the computer. I can say the colors are darker on the tv and this is just due to the nature of the screen size. Newer LED tvs may be better, but mine is only 1 1/2 years old.
For an external display, just go to the educators link, select your college and you get $100 off. My wife is an educator and I am back in college so it's no hassle. Or they just ask for an ID. I own 2 24" ACD and they are nice. I do photography and a screen calibration is a must. Once done you'll be happy. And docking with the laptop is handy.

Where can I purchase a LED screen for my 13" MacBook Pro?

My 2009, 13" MacBook Pro screen needs to be replaced. It fades to white minutes after I boot up. Apple charges over $400 to replace a screen. Or they will outsource the replacement for $250. I have been repairing all my computers for years. I don't want to pay out a bunch of money for something I can do myself. I can't seem to find a reputable dealer who sells the correct LED replacement screens for my Laptop. Will somebody here give me the names of places where I can buy a screen? Thanks in advance for your help.

I just bought a new iMac and now I am trying to use it as a screen for my Macbook pro, but it don't have a Mini DisplayPort the new model only have Thunderbolt which my Macbook don't have. Is there any way to connect this two mac's anyway??

Screen sharing setup in 10.5, 10.6 are described by the links by operating system. 10.7 is fairly similar to 10.6.
And if both Macs have Firewire, you can setup a Firewire over IP network for fast communication between machines. Note if you have two different Firewire ports a 6 pin to 9 pin Firewire cable does exist. There are no Firewire to USB cables.

Mac Pro 3,1 Stuck on Grey screen for 1 min during boot

I have a Late 2008 Mac Pro 3,1 and have started experiencing a very slow boot up. The computer gets stuck for over a minute on the initial gray screen after the first boot chime. Once the apple logo finally appears the boot goes normally. Once running it seems OK. The shut down seems normal with a grey screen for a few seconds with the "clock" logo.
Symptom:
After the chime I see a blank gray screen for in excess of 1 minute, it used to last only a couple of seconds.
Once the dark grey Apple logo appears the boot goes at normal speed
I have a number of different hard drives with older systems and booting from each of then gives the problem - so it does not seem to be system/disc related
Two partitions (Mavericks and ML) are on SSD's installed on a Sonnet PCIe Card and showed the same problem as the spinning hard discs.
I tried: (following a trawl of the bb's etc)
I repaired permissions and repaired all discs for all my boot partitions (10.5, 10.6, 10.7, 10.8 and 10.9) using the appropriate Disc Utility
Zapping the Pram - this was very strange as I had to keep the cmd alt P R held down for around a minute before the second chime occurred, the time of the grey screen stays stuck
Resetting the SMC
Booting in Verbose Safe Mode: Again I had to hold the Alt V down for a minute on the gray screen before the screen went black and the text appeared
I looked on the console log but could see nothing obvious, additionally from the verbose safe mode boot the text log seems to start from when the grey screen disappears. The time stamps show the boot finishing in well under the minute I wait.
Any suggestions you may have are very welcome.
Regards
Dave

Thanks The Hatter for that information. The blank gray screen is now lasting 3 mins before the Apple appears. When I restarted the system log is as below. As you can see there is just over a three minute gap between the shut down and the boot, indicating to me that it is not something in the system software after the boot but a problem at the very start. It does look like it could be something to do with the hardware as you suggest. I have verified all the discs with the disc utility and they report as OK and their SMART status is also OK. I have disconnected the external drives with no change so I will now have to do a thorough check and systematically remove the internal ones but that will have to wait for the weekend.
I have Mavericks on the Samsung 840 Pro and ML on a Crucial SSD (Crucial_CT240M500SSD1 Media) on a PCIe card. The Mavericks install I think was an upgrade, not a clean install done quite a while ago. I only noticed the problem this week when I re-booted in an ML to run some software not compatible with Mavericks. I have made a system back up as a precaution to an external disc just in case my main drive is dying!
There are some firmware updates for both the SSD discs that I have not applied these yet but I will leave them out of the mix until I have tried simplifying my configuration with a single disc.

Need HDCP-recognizing Bootcamp Windows driver for MacBook Pro's screen

I need a Bootcamp Windows driver for my MacBook Pro 15/Retina (MBR) that recognizes that the MBR's built-in screen in HDCP-compliant. The current Bootcamp drivers for Windows do recognized HDCP on an external HDMI-connected display, but do not recognized HDCP on the internal display.
BTW, I've read some statements that Windows drivers don't recognize HDCP via DisplayPort connections, so I wonder if Apple is using internal wiring that acts like it's a DisplayPort connection?
Please do not suggest things that only enable disabling DRM HDCP protection from Blu-Ray discs. I need a solution that to cooperate with DRM HDCP protection for content from live tuners, not from a Blu-Ray or DVD disc.
My application is using Windows Media Center (WMC) to play streaming content from my Silicon Dust HD HomeRun Prime (HDHR3) cable TV tuner on my MBR's built-in screen. This works fine with an external HDMI-connected (HDCP-capable) display, but I also want to get this working on my laptop's screen for when I'm stuck in bed (illness, bad back, etc.). The only application Silicon Dust offers for viewing HDHR3 tuner output on Windows (or any platform, as far as I know) which supports all protected cable channels is WMC, and WMC relies on the Apple-provided Windows NVIDIA drivers for HDCP capability. The NVIDIA Control Panel explicitly recognizes my external HDMI-connected monitor's HDCP capability, but does not recognize the MBR's internal screen has having any HDCP. This causes WMC to prevent the display of any TV channels at all from the HDHR3 when the only screen is the internal one (and it blocks DRM-protected channels if both screens are active in parallel).
I'm thinking that the best solution would be an NVIDIA driver for the built-in GeForce GT 650M for Windows 8 (or 7) which recognizes HDCP capability via DisplayPort. Is there anything like that? Or, alternately, some add-in driver that adds a layer of HDCP capability recognition to the standard drivers?
Is there any currently-available solution? . . . something that will enable the internal screen to play all the tuner's cable channels including DRM-protected ones (either on Bootcamp'ed Windows or on the OS X side)?
P.S. -- FYI, the only other potential app I've read about for using an external tuner with a MacBook is an OS X version of MythTV, but (a) that requires an excessively long list of geek tweek steps (install an SQL application, create an SQL database, do lots of command-line tweaks, add & configure a backend app and then a frontend app, ... ) and (b) even then it seems it doesn't support channels that aren't marked "copy-freely", i.e., HDCP-enabled DRM protected content.

Strange -- sig's comment seems gone now. I wonder why.
Anyway, I did try the latests NVidia drivers yesterday, afterall they explicitly say they added HDCP over DisplayPort, but no joy. In the NVidia control panel (for Windows), external displays via HDMI have a left-menu section for HDCP that explicitly shows it's working, but there is still no such indication for the internal display, and I am still unable to use WMC with HD HomeRun Prime cablecard tuner to play anything on the screen except channels that the provider marks "copy freely" (e.g., Bloomberg news channel 722 isn't playable, but MSNBC 723 is playable).
My guess is that maybe laptop internal displays don't explicitly have internal DisplayPort and HDCP technology but have some kind of exception that normally allows playback?
As an alternative I wish there were cablecard tuner playback software on the OS X side that could play more than "copy freely" cablecard-tuned material, but there doesn't seem to be anything comparable to Windows Media Player that supports that. (Now it should be clearer why this discussion belongs under MacBook Pro and not under Bootcamp where the moderators moved it.)

Shouldn't Apple recall and provide FREE replacement for MacBook Pro screens with ghosting and dead pixel issues?

Read the forum posts, Google the issue, watch the YouTube videos on the problems; they are everywhere. I purchased a 2012 Retina MacBook Pro and the screen is riddled with dead pixels, white ghosting throughout, and image retention issues, all from a company that promotes the quality of the product they sell. There's no way this issue facing so many consumers shouldn't result in Apple replacing these screens for FREE.
I purchased the high-end machine for photo and video editing. Photo editing is particularly difficult when I can't tell if I have dust, dirt or colour shifts in my images or if it's just the screen overlaying these issues. I've never had so many issues with any screen I've purchased, from my Panasonic Plasma TV to my cheap ACER laptop. Please Apple, quit ignoring this issue.
