MacBook Pro :: Screen Continuously Flash / Blink On HDTV
Jul 28, 2010
Since the day I got my MBP two months ago I have always had it hooked up to a small HP HD monitor via HDMI. The other day I tried hooking it up to my 32 inch HDTV and now I am experiencing a weird problem. The TV and the Mac recognize each other but the screen continues to flash/blink every second (almost like it is loosing conenction). I check the cords and everything is fine which I assumed because everything is fine when I'm connected to the HP monitor.

I've had my 15" MBP for just over a month, it was a refurb purchased direct from Apple. I've noticed the video issue where the top 1/2 of the screen would flash, blink. It's happened maybe 3 or 4 times. It seems to only happen after it wakes from sleep and the only fix is to reboot. I know i can switch the video card over and from what i read, it solves the issue.
Here's my question, since I can't get it to do it on demand, ( i did however record a video actually 2 on 2 separate occasions) should i take it in for repair now? will the problem get worse? or should i wait it out for bit in case something else goes wrong down the road??

Every once and a while, usually when my MacBook is running on it's battery, the screen will show a black screen for nearly only a millisecond or two. It's not too bothersome, and it usually blinks back to normal before I can notice it, but nevertheless I don't want it, and from what I can recall, this only started happening after I installed the Snow Leopard Graphics Update. Is anybody else getting these problems on their MBPs or MBs? MacBook config details in my sig.

I've got my MacBook attached to my 40" Sony Bravia HDTV (KDL40W4500), and when I mirror the display or use the HDTV as the primary screen it cuts off portions of the screen like the main toolbar on top, as well as some of the dock. I tried to change the Screen Format on my TV but that doesn't seem to work, does anyone know how to fix this?

Macbook Pro 15". Product #: Z0GG
Backstory: Sunday the updates window popped up so I let it run and reboot. Boot screen is stuck on the white screen with apple logo and spinning icon. None of the typical hotkeys were working like the Shift key to go to Safe Mode. I decided to resinstall Snow Leopard which went perfectly fine since I was able to boot off of the Install DVD. Everything seemed fine after the install and I had all of my previous programs and files.
It worked fine all day yesterday until I shut the lid to leave work. I got home, opened the lid and the spinning mouse icon was continuously spinning. I could move the mouse but couldn't click anything. I shut it down using the power button. Upon booting it up I did not hear the boot up sound but a white screen displayed and didn't do anything from there. I rebooted it again, inserted the Snow Leopard DVD to try and boot off of that and it won't even boot off of the DVD. None of the typical hotkeys work either, not even to eject the DVD. I do hear the DVD spinning up but it doesn't do anything; just a white screen.
I did reset the PRAM which forced it to reboot and I got the startup sound back but it still only shows a white screen. Any ideas? I forgot to purchase Apple Care last month before my 1 year warranty ran out so I'm 1.5 months out of that.

I have a 2010 Macbook pro and I just ordered a minidisplayport to HDMI cord. I was able to get it all set up to my Sylvania 22" HDTV HERE but I can't seem to get the resolution right. I've tried multiple resolutions both via the control panel and NVidia's control panel. Keep in mind I'm running Windows 7 via bootcamp. I'm able to get the resolution to look pretty clear, but by doing so it cuts off the edges of the screen, where as if I get it so it all shows up on the screen, it doesn't look as clear.

The top and bottom of the display is cut off when viewing the screen on my Sony HDTV using DVI output with mirroring on. I've tried changing my display resolutions for the Sony from my Mac display preferences as well as changing the display format on the Sony side to no avail.

I'm using a DVI->HDMI cable to connect my Powerbook to my Sony LCD TV. The Sony's native resolution is 1366x768. For some reason my Powerbook doesn't want to switch to this resolution. I can get 1280x720, but this leaves a black border around the images the whole time.
I've tried setting a custom resolution using the trial version of SwitchResX but to no avail. It won't do it.
Anybody have any similar experiences and possibly found a fix?

I'm thinking about buying a mac mini to use with an HDTV as the primary screen. I've read some other posts regarding this. My question is, which method of hooking the setup up (i.e., which cables) provides the best picture. I've done this with a PC before but the connection was crumby... is this the case with the mac mini? Will I be able to get the same resolution that I can in a monitor? Also, I have looked at a ton of HDTVs and find the picture to be pretty bad compared to older TVs. Can anyone reccommend a model in the $500-700 range that has a good picture.

I have a Sony Bravia 32 inch HDTV and would like to display movies downloaded to the iMac on the TV. TV has HDMI inputs as well as a USB socket. Can anyone tell me whether it is possible to achieve this aim?

I've seen a few posts about this problem on Macrumors and through Google searches, but I haven't found a solution to the "Black Border" problem some of us are having when connecting Macs to HDTV's via HDMI cables. Nor am I certain what the cause of the problem is: Mac?, TV?, HDMI cable length?
For me, resetting PRAM by holding Command-Option-P-R at startup and waiting for two chimes removes the black border for up to several computer restarts, but eventually the border comes back until I reset PRAM, again.
I have a 55' long HDMI cable from Monoprice ("HDMI Tin-Plated Copper CL2 Rated (For In-Wall Installation) Cable (22AWG) - 35ft (Gold Plated)") running from a Mac Pro with an ATI Radeon video card to a 52" Mitsubishi 1080p HDTV.
To clarify, this is not just a black bar at the top and bottom like when watching certain DVD's, but a black border around all four sides that effectively reduces the size of your TV from, e.g. 52" to 46" whether watching movies, surfing the web, or otherwise using the Mac via an HDTV

I have everything connected and working to display my MBP to my Sony Bravia HDTV. I am using the TV as a second display. When I choose full screen for my iTunes movie, it goes black. The iTunes movie plays in reduced screen. Does anyone have a solution how I can play full screen?

I have a 27" iMac and an LG 47" 1080p HDTV. I just bought the Griffin Video Display Converter, which is certified by Apple to pass both video and audio from the mini display port on the late 2009 iMacs. Whenever somebody turns on the HDTV the iMac's screen flickers the color blue on and off, sometimes staying that way permanently. Permanently the color blue that is. The only way to get out of it is to turn the iMac off and then back on (restarting it).I have the ?Mirror Displays? checkbox checked in the ?Display Preferences?. When I uncheck that box it treats the connected HDTV as an extension to the iMac display, whether the HDTV is on or off, which makes my cursor disappear off one side of the screen. This is why I leave mirroring on.

The first time I connected to my HDTV using a mini displayport-dvi and a dvi-hdmi adapter, it worked flawlessly. Stupidly, I set my TV to a resolution it couldn't support. Now the screen only turns blue until System Preferences eventually crashes and the TV gets no signal.
I've tried clearing my PRAM, deleting the profile in the colorsync folder, and even deleting /Library/Preferences/com.apple.windowserver.plist out of desperation. I've confirmed that it's not a problem with the adapters by successfully getting another HDTV to work. Where could could OS X be storing the display's settings?

I am using a Macbook (white version) and I am using a mini-dvi to vga adapter and its in the highest resolution it will go, and I have tried all the other resolutions as well, and it still does it. The problem is that the screen is acting like its to wide to fit the TV, it cuts off like a fourth of an inch of screen on both sides, and I have no clue if there is a way to fix this, but I reinstalled leopard a while back and thats when I started noticing it.

My Macbook is brand new! (Barely 4 months old) Just recently my laptop will flash a black screen. It starts from the bottom and quickly flashes up the screen higher and higher each flash! i have read on some other pages it is a bad inverter on the inner core of the Macbook. Other than that I do not know what to do!

I am using an imac OS 10.5.8 When I click on system preferences it just gives a little blink but wont open, doesn't load from the icon in applications either. All I can think is that one of my kids may have trashed it but it's doubtful. What could have happened? Do I need to re-install OS?

I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?

I'm having some issues with my Macbook Pro that just arose today. Randomly, when I'm on Safari, the screen will flash a little and the icons at the bottom will disappear. They will come back in a couple seconds and pop-ups that I usually only get when I first log on will appear. Safari also refreshes the page I was viewing. I did a little research and thought the issue might be google drive, but I do not have it installed on my Mac.

I noticed that all the flash videos played inside Safari on my MBP were slow and choppy when switching to full screen mode. This started happening after upgrading to Flash 10.1 r85. I disabled hardware acceleration on Flash's settings, and video playback went back to normal.
What can I do to use hardware accelerated Flash, but without the slowdowns?

Ive recon that when having your MBP's GT330M turned on, you can't play YouTube-videos in full-screen, my screen just turns white, and nothing happens.. Then you have to ESC yourself outta there..
The funny thing is that if you use the Intel HD Graphics processor, it works fine, but it gets very laggy if you have 720p res..
Is there anyone else having this problem?

I have 4GB of RAM on my (aging) MacBook Pro and use a very useful app called Memory Clean to maximize the RAM from time to time.
Recently, my laptop has been getting slower and slower to the degree that even opening windows in Finder brings it an almost complete standstill. When I checked the RAM it had decreased to under 10MB.
What I've found is that I can run Memory Clean and the more I run it, the more is freed up and the quicker the laptop runs (up to 2GB+ being available). However, within minutes it is plummeting again and so I have to rerun Memory Clean. Suffice to say, the laptop as a whole seems to be struggling.
What can I do-and is this a hard drive failing issue or something else?
