I have a strange pattern on 80 percent of my screen

I have a strange pattern on 80 percent (or more) of my screen. It does appear that underneath the pattern, my computer is working. I know that because on the right side of the screen, the mouse is able to click files and applications and open them. Does anyone have any constructive thoughts? Below is a screen shot.

Does your model Macbook Pro qualify? 
MacBook Pro: Distorted video or no video issues .  The affected computers  were manufactured between approximately May 2007 and September 2008.

  • Intermittent problems with strange patterns on screen

    My new (refurbed) 17in Intel Imac starts up periodically with a strange pattern running at 45 degrees across the entire screen (little multicolor boxes or rectangles) then the screen goes to all blue and freezes with no further activity. I have run the hardware test, reset pram and disk utility with no solutions. It will still boot up perfectly about every 3rd attempt. I'm running 10.4.10. Any help would be greatly appreciated.

    To make sure that this is not software related, set it back to factory settings, without using a backup afterwards, described in this article:
    Use iTunes to restore your iOS device to factory settings - Apple Support
    If the screen has still this pattern, the issue is hardware related and the phone needs to be serviced. In that case it might be enough to let Apple replace the screen.

  • Is my i7 MBP GPU malfunctioning?  Strange pattern on screen?

    Happens in the morning after the computer has been sleeping all night.
    Diamond shape artifacting I guess?
    Computer runs for about 3 minutes, then screen gets a strange pattern across it, then locks up.
    Looks like this after the hard boot.

    After I leave it on for a bit and let it warm up reset the power then it boots like this.
    http://dl.dropbox.com/u/428893/Mbp/Movie%20Dec%2002%2C%209%2013%2043%20AM.mov
    After it gets to the desktop things are really crashy and don't load properly, so a 3rd boot is needed.
    After 3 reboots the problem goes away, so what ever it is I assume needs to warm up before it works right.
    Its obviously hardware related, I suspect my logic board / GPU need to be replaced?
    All this happens as soon as I move to Mexico where there are no Mac service places around!
    Anyone know if mac will ship replacement parts for user serviceable components?

    Unfortunately, this does have the look of a hardware problem, probably having to do with a graphics chip. Have you tried running the extended version of the Apple Hardware test? You might get an error code which would indicate where the problem is.
    There is a way to contact Apple in Mexico--you might want to do that and see what options they can offer you:

    Good luck!

  • Strange pattern artifacts

    I have been concentrating on newer images since getting LR and this does not happen with shots from my newer camera, but I went through some older images today and found something that wasn't there before LR. I am getting a strange pattern artifact, like a maze, when viewed at 1:1. It shows up in areas from mid and brighter and makes edges very jagged. These same images looked fine when using ACR 3.6 and earlier.

    Maybe while previes were being built?

  • GTX 580 Twin Frozer II freezes with strange pattern

    I bought a MSI N580GTX twin frozer II yesterday and have some strange problems. In DirectX 11 Applications (tested 3DMark11, Unigine Sanctuary DX11, Unigine Heaven DX11 Benchmark and Civ 5) after some time (~20 s in Sanctuary, 1 h in Civ 5) the app freezes (sound still playing) and the screen shows a strange pattern. Images can be found here: http://imgur.com/a/c7G8p. In the Civ 5 screenshot the pattern is a bit hidden but similar to the one in the sanctuary screenshot. Sometimes the app also freezes just like that without pattern or is showing strange fog. It seems that this appears only in (some) DX11 apps - not in OpenGL 4.x or lower versions of both. Furmark for example runs without problems. The card never got hotter than 70° up to now.
    Does this indicate a hardware problem or could this be a driver issue?
    I installed 266.58 drivers. Currently I am trying 267.31 but with no success. Before I had a GTX275 and never had any problems.
    Other system specs:
    Windows 7 (no service pack)
    Mainboard: GA-MA790XT-UDP5P
    CPU: AMD Phenom II X4 965
    RAM: Kingston 4x4GB
    HD: OCZ Vertex 2 and 2 TB HD
    700 W power supply

    you're welcome

    so I'll see if this strange error appears again. Hopefully not ...
    I expect soon or later issue to come back, since basically we change nothing compared to original state
    But let see... if issue come back we can fix it by one or other way

  • Why has my monitor suddenly begun to have a moiré pattern all over – it is even showing up on my icons on the dock? It appears to be very thin bright green vertical lines. I have a 2008 iMac which is running 10.6.8. What does this mean?

    Also experiencing some funky issues with my wireless keyboard. With new batteries, it will just stop functioning. Certain keys intermittently won't work. Also the fans go on as soon as I turn the computer on - some times they stay on and sometimes they don't. Ever since upgrading the operating system - I've been having many issues with this iMac. Not happy. Any answers out there?

    Thanks for your reply LexSchellings, There is no disc in the drive and I went through the suggestions you put forward on the phone with Apple support without any luck. I can put a disc in but it pops straight back out again without registering on finder.
    The idea of using an external drive was to enable me to avoid the cost and loss of productivity whilst machine in repair... if I have to take it in to get the old drive removed than I might as well have a new internal drive put in, although I do worry about the reliability of these apple drives given my experience with this one coupled with my limited online research ... on line forums seem to be full of people with the same problem (although perhaps searching such forums is bound to make it seem a common problem as users with perfectly working machines are less likely to post (?)) Your reply suggests that no external drive will work whilst the existing drive is in place.
    As a postscript: I do realise that this is a user forum ...my secondary question was asking if anyone knows how to put forward a case/complaint to Apple... I can't find a link on the support page that would enable me to do so and I was wondering if anyone on this user forum had any ideas/experience..

  • Hello,  I have a strange file in my Users folder, named PortDetect.log I have no idea which app created it and it reappears when I delete it.  Has anyone got the same file? Or know where it may originate from?  Thanks in advance!

  • Hello, starting with today I have a strange problem: all events are correctly shown in the finder but in FCP-X there`s`none and every time I open it creates a new event. What is wrong?

    Hello, starting with today I have a strange problem with Final Cut Pro X: all events are correctly shown in the finder but in FCP-X there`s`none and every time I open it creates a new event. What is wrong?

    Here`s the screenshot.
    But anyway:
    The drive is Makintosh HD from my Macbook and it is shown in the event mediathek and in the projects. Since I`ve recognized this problem I installed FCPX again and consequently the event and project directory created by FCPX is where it should be and it shows all the test events including it`s files.
    So what happens? Opening FCPX you see only one event and that a new empty event. All previous events are not shown there even if you can see them in the finder. So if you import again the clips they are in this new event library. After closing correctly FCPX and reopening there again is nothing than an new and empty event. What it does is that it recognized that i.e. there are events with previous numbers and so it creates an new one with the next available counting number.
    If you want to open one event from the finder it by clicking to the file it opens FCPX but it says it cannot open the clicked file.

  • CS6 Camera Raw - I can now only crop using aspect ratio in the custom crop setting rather than being able to set the dims in cm and inches? anyone know how to revert? ever since installing new mac operating system things have been strange!

    CS6 Camera Raw - I can now only crop using aspect ratio in the custom crop setting rather than being able to set the dims in cm and inches? anyone know how to revert? ever since installing new mac operating system things have been strange!

    Hi Kglad.
    I have looked at all of my settings both in Bridge and CS6 Photoshop regarding Camera Raw. I am at a loss how to set the crop tool in cm or inches as I once did - now the only option is to crop using ratios of 1:1 etc etc - This is infuriating as lots of my square crops I could set at 10" x 10'' specifically to print one to one to fit frame and mount size -
    Now if cropping using bloody aspect ratio of 1:1 (square) the actual dims of the crop are roughly 4.25 inches x 4.25 inches. this means I then have to open the whole image in photoshop in order to crop at the dims I have set! It was so much quicker in terms of batch cropping in camera raw being able to set dims in centimetres and inches but they have gone and mucked around with it, with the new bloody update! Unless you are an absolute genius and know how I can go back to having an option of CM, Inches and aspect ratio within the custom crop settings? (Please say you do)
    here is the new tutorial for CC -  my guess is they have scrapped the control we had over the custom crop settings

    So you are saying that you followed all of the steps in the support document for problems with connection, including removing and reinstalling iTunes? You do not say what you have tried, so it is hard to make recommendations. If this is the case, then you have tried resolving driver issues? What if you go to Device Manager and look for the iPhone. You should be able to click on it and see about drivers. You can update/reinstall the device driver.

  • Stuck with grey display and strange pattern!

    My iMac froze a few days ago, so I used the power button to turn it off. Then I restarted  the computer but I had a greyish monitor with the apple logo, and they were filled with little suigly lines. (see photos)
    Then the screen gets a strange pattern on the left side
    and after a while I get the text box telling me to restart.
    But each time I retart I get the same thing, so impossible to open the computer
    to get access to Terminal or Activity Monitor to try and change things.
    Any suggestions?

  • I have a strange noise coming from within my 2011 iMac Desktop.

    I have a strange noise coming from within my 2011 iMac Desktop. This started 1 week ago and is intermittent. It sounds like an electronic drill. I have removed all external connections and powered up the Mac and just left  it running. Some 2 hours later the noise started. On hitting the space bar on the keyboard the noise stopped. I did a similar test and the noise started within 2 minutes so I have discounted any overheating issues.
    With keyboard activity there is an increase in the frequency of this fault.
    If you open safari when the fault reappears the URL web link text starts flashing at the same frequency as the noise. This fault can appear with or without the noise.
    I’ve been typing these details out on Word and as soon as I went to save  the document the noise started  and as soon as I hit the OK option in the save window the noise ceased.
    Any thoughts will be appreciated.

    I think this issue might be related to my wireless Keyboard. have just noticed that certain combinations of keys do not work. The Right hand shift + ? didn't work but started this noise. Hit another key and the noise stopped Also I have problems using the right hand shift key with the letters  Y, H & N , they don't work and are all in line.
    So I'm taking the keyboard back to John Lewis. it will be easier to carry that the screen !!
