Fuzzy/shimmery streaks - 'pixellating': why?

Is this more likely a software or hardware issue?
Intermittently I get streaks, or patches, of 'pixellated' areas.
That is, streaks that are blurry because there are vertical lines that look like crude pixel areas (as if some pixels had dropped out).
This isn't the dreaded horizontal black/white lines that the screen breaks up into when the motherboard is going out. It's patchy areas, rather like streaky shadows; plus grey gets overlayed with lavender, darker blue with light blue.
I've run Tech Tools and the VRAM gets a clean report (while the pixellating is actually happening). Immediately after completing the Tech Tools tests the problem went away. It also sometimes goes away on restarting, but sometimes not.
I have the impression that use of one of the widgets (Sudoku) triggers the pixellating - but that may be just coincidence.
Any suggestions? More likely a software matter? Video card?
If software, is there any program out there to help diagnose and/or adjust and correct the problem?
If hardware, is there any remedy? or will the whole logic board have to be replaced?
All help and advice gratefully received.

Anthony,
An earlier post referred to a known problem on the Wallstreet but it was only the Wallstreet with a 13.3" display. The data ribbon cable connector on the back of the display would work loose and squeezing on the connector would correct the problem for awhile. I have not read of any problems with the Pismo's connector.
A few possibilities:
- A worn/damaged ribbon cable where it passes through the clutch (hinge). This is one weak point on any 'book that has a high number of display open/close cycles. Try moving the display from almost closed to almost fully opened (close to 180º) and see if the image changes. If the cable is damaged, you will have to disassemble the display to replace it.
- Less likely but worth a look...remove all power > lift off keyboard (lay it face down on the palm rest) > remove aluminum heat shield > disconnect/reseat the display data ribbon cable connector on the logic board. You can see the cable if you enlarge the bottom picture of this link; it is disconnected and emerges from the left hinge.

There is no need to remove any more components than I have mentioned to access this connector.
Of course there is the possibility of a loose connector on the back of the display but it does look like the connector has tiny snap pins or screws holding it in place.

    If I paste the jpeg on a draw page and shrink it to fit, fuzzy print. If I create the text directly on a draw page, it's fine. (That suggests to me the problem isn't in the printer.) But I want to include a small drawing on the card, and the pasted jpeg of that small drawing is very poor quality.

  • Fuzzy screen, moving pixels, only in colour, not in grayscale NOT zoom prob

    Hi,
    I was using messenger on my macbook, which is about 30 days old, and the screen began to go a bit fuzzy in one patch, I closed the program and now the screen is just fuzzy all over.
    The best way to describe this is like a telly with interference, there are visible pixels in the wrong colour, its almost impossible to read, when you highlight areas the pixels which are dodgy change and its generally all fuzzy.
    This is not a zoom problem, I have updated all software downloads AND when you turn the computer into grayscale in universal access the problem goes away, its only there when its in colour!
    There a screen shot of the problem here:

  • ?? Forwarded pictures in apple mail become pixelated,, WHY ??

    Help!
    I'm using Leopard and apple mail 3.2.
    Yesterday I received a email with several great pictures.
    The photo were high res and I wanted to forwarded them to my family.
    So far so good ... they went out fine.... BUT everyone that received them said that they
    looked terrible. I asked them to send/forward back to me and WOW they are terrible.
    It appears that they were compressed severally.
    I understand that using iPhoto, you have the option to change the size of the image.
    But .. I can't find any setting anywhere that gives a option to compress or not in mail!
    Sure I can drag each photo to the desktop and then send them out as a attachment...
    But why do I have to go through this mess?
    BTW: I have never had this issue in my 20 yrs. of using "windows"
    I really need a answer... please help
    Chuck

    Chuck,
    Welcome to Apple Discussions.
    When you select the forwarded message and choose forward, there should be a drop down menu in the bottom right corner of the forwarded message window which allows you to choose the Image Size...Actual/Small/Medium/Large.
    Have you tried that setting?

  • Jpeg photos look fuzzy - do you know why?

    Hi,
    I've imported several jpeg photos into FCE and put them in my timeline. When my playhead is over the picture, the image looks perfect in the canvas window, but when I hit play, the picture in the canvas window gets fuzzy regardless of whether the image has basic motion or is just still. Any ideas how to fix this problem?
    The render status bar above the photos is green, so I don't think I need to render them.
    I really appreciate all the help you all have given me so far and that you're reading this now - thank you!
    Lisa

    Green means it needs to be rendered for output. You're watching a lores playback. Render it and look at the output on a video monitor.

  • PDFs as desktop background is pixelated - why?

    Recently upgraded from 10.4 to 10.6, and from there to 10.7.  I'm in the habit of using PDFs of line art as my desktop background.  In 10.4 they would appear in full resolution, but now that I've upgraded they have huge pixels visible (see image).  What changed and how can I change it back?
    (Originally posted to 10.6 area, duplicated here now that I'm on 10.7 in hopes of more help.)

    Hi SaintPatrick, and a warm welcome to the forums!

  • Picture taken wth iphone 4s  is fuzzy and double inage.why?

    wh

    Thank you, Courcoul. I will check out the Fast Camera and Blux Pro. They could come in handy for other photo-taking activities. However, I'm not sure it's going to solve my white-out-overexposure-blurry problem. Shouldn't we expect Apple's camera to work properly, without any special apps to make it behave for standard type stuff? Especially for the price we pay to own an Apple. It's a drag when you see a Samsung taking good pictures and zooming in without losing focus. I like your advice for other specialized apps, though. Much appreciated. And I will check into them.
    If anyone can shed some light (no pun intended) on the over exposure white and out of focus issue with concert photos, I'd love to hear more suggestions. Thanks!!

  • Why PDF documents are missing icon of standard size?

    Hello,
    My Adobe Reader is v11.0.6. It was originally installed on Win XP Home and worked OK.
    Recently, I've moved it to Win7 Pro with the aid of Laplink PC Mover. It works OK, but PDF documents are missing its standard size icon, e.g. on Desktop. Precisely speaking, my closed PDF documents display as their icon the first page of the document with almost invisible miniature of PDF icon in its right lower corner.
    I tried to take care of it with re-association and re-choosing right icon. This corrected the situation for a few seconds only.
    I repaired the Reader installation also with the same effect.
    The icon chosen is located in: C:\Windows\Installer\{AC76BAB6-7AD7-1033-7B44-AB0000000001} \PDFFile_8.ico. It's  of 256x256 pixels
    Why this happen? How can one repair it?
    Andy148

    Open Windows Explorer -> Tools -> Folder Options
    Go to the View tab
    Check "Always show icons, never thumbnails"
    Hit Apply
    All your PDF files on your desktop should now show with the generic PDF icon.

  • My ipad screen is shimmering green and pixelated.  What's happening

    My ipad screen is shimmering and pixelated.  I've tried restarting and restoring from backup.  Everything still seems to work, but the screen looks shimmery and pixelated.  How do I fix this?

    I have an old iPad 3 that has taken a beating, and the screen occasionally shifts colors (blue, green, or red).  It would look about like this:
    http://ipadhelp.com/wp-content/uploads/2013/10/ipad-screen-colour-problem-620x40 0.jpg
    This is going to sound dumb, but this always fixes it for me:
    Lay the ipad flat on your lap, open your hand, and with fingers spread, gently but firmly smack the screen of the iPad.  I sometimes have to do it 3-5 times (mostly because I'm afraid to hit it too hard!), but it consistently resolves the problem for me.

  • How to save document with pixel aspect correction?

    I have a document which has has a non-square pixel ratio thus requires pixel aspect ratio correction to be turned on to view the image correctly.
    I want to save it as a JPEG for use online however I cant find an option anywhere to make the saved file have the corrected aspect ratio.
    Essentially when I save the file as a jpeg (or any end format) the image is squished. How can I save the file not squished? (ie. burn in the ratio correction)

    As I still work with a lot of Images, being used in SD Video, where non-square pixels are the rule.
    I Save_As PSD, and Import those adjusted PAR (Pixel Aspect Ratio) Images. However, that does not work in your case. I have never used JPEG, but wonder if that format is fully supportive of non-square pixels - never needed JPEG, so have never investigated.
    As Web display is on a computer, with square pixels, why the use of non-square pixels for the Web? [Just curious]
    Good luck, and wish that I had more to offer, perhaps PNG?

  • How do I read inches instead of pixels, in the develop module

    How do I read inches instead of pixels, in the develop module. I am not discussing resolution. When I crop, I need to see the numbers in inches, not pixels.
    I am not exporting to anything. From the develop module I go on to the print module. However I want to see inches, not pixels, in the develop module.
    I am not cropping to an aspect ratio. I am cropping to a given size, in inches, just as if I was in PS CS 3.

    >Instead of the image in pixels, why can't I read it in inches? Physical size in pixels is staring at me, why can't inches be there instead?
    Because it is not there. The size in inches ONLY becomes real at print or at export time and can and will change depending on what you do there. Before that you are looking at a number of pixels in a computer.
    >I need to set these values in the develop module, just as if I was setting them in PS CS 3.
    That does not make any sense. There is no need to set this in develop at all. Lightroom will scale to your final size at export/Print/web/slideshow. Not in develop. There you are working with the RAW data at its native size.

  • Why use floats in graphics methods?

    Since coordinates are specified in pixels, why do
    methods like Line2D.Float() take floating point numbers
    instead of integers? Dont floats take more time
    and memory?

    As far as I know, float calculations indeed require more processing power as apposed to integer ones. I'm not quite sure why floats and doubles are used in a number of graphics related methods either, because it's not quite likely you'll ever have a screen dimension of 1024.78 by 768.54 for instance (yet, class java.awt.Dimension returns width and height of screensize as doubles!).
    I think a float, like int, consumes 32 bits -thus 4 bytes- of memory space. So as far as memory goes, there's no difference.
    Could someone else enlighten us regarding the use of float and double precision variables where it -at first glance- doesn't seem to make sense?

  • A Case Study Question in the Use of Stills with Final Cut Pro

    Believe it or not, for the last week I have been reading endlessly about pixels, resolution, aspect ratio, Photoshop resizing, the bloody battle over the usefulness of the term "dpi" in video discussions, and generally about what one should do in order to use still images in a film edited in Final Cut Pro. And yet, though I have a PhD from an Ivy League university, and can understand a lot of things, I am sorry to say I am still at a loss.
    Much of the discussions of photos on forums like this one are either quite technical or broadly philosophical. But my questions are completely practical and specific. I am not a photographer or a printer, nor am I an experienced editor. I am just a fairly smart person trying to use photos in his film. So I am going to ask some specific questions and hope for specific answers, without any philosophical waffling or technical mumbo jumbo.
    I have one of those HP all in one printer/fax/scanner machines. I am told this device, while not fancy, is perfectly adequate to the task. Some of my photos I scan with this device from prints. Some of them I get from other people. (I have stopped downloading photos from the web, as the quality is nearly always poor.) I have Photoshop Essentials (not Photoshop). I am making a 90-minute HDV documentary, 16x9. The doc is mostly HDV footage with a still here and there. I want to be able to move on the photos (zoom, pan, etc.). I want, obviously, for them to look good. My sense is that the work flow is: (a) scan the photo (or obtain from some source as a digital file); alter the photo in some way in Photoshop; and (b) import the photo into your FCP project.
    Question #1: If I have a 6x8 print, what settings should I scan it in with -- is it possible there really is no difference between scanning in it at 72dpi and 300dpi? Is it really all about the dimensions of the image? Isn't a photo whose dimensions are enlarged in Photoshop to make it available for panning and zooming in my sequence going to look fuzzier and more pixelated if it was originally scanned at 72dpi than at 300dpi? Also: Does it matter if I save it as a jpeg or tiff? Bottom line: What settings do I use in my scanning software when I scan a photo for this purpose?
    Question #2: Once I have the image file on my hard drive, I suppose I now have to load it into Photoshop Elements and do something to it. What is it exactly I am using this program for? I'm going to take a wild guess. I use PS Elements to (1) crop the photo so that it has a 16x9 aspect ratio, and (2) resize it so that I can do pans and other Ken Burnsy moves on it in FCP. Bottom line: What exactly do I do in PSE to the photo and what settings do I use to both (a) make it available for moves and (b) not injure the quality of the photo by increasing its dimensions?
    (In passing, I will say that I have done experiments that show that if I increase a photo's dimensions to, say, 4000 pixels by 2000 pixels, the photo's quality definitely and obviously suffers. I don't understand how a picture can be increased in size without losing sharpness. So, what am I doing wrong? Is this a function of it having been scanned in improperly to begin with?)
    Question #3: If I am obtaining a photo from an outside source -- say, a professional photographer -- what are the specifications I ask for in both a hard print and a photo file? If the former, what dimensions do I ask for? If the latter, do I specify resolution and dimensions and file type?
    These are my questions. At this point, I really don't want to know WHY any of this is the way it is. I just want someone to say: "Do this; do this; and then do this."
    Thank you very much.

    Studio X is absolutely correct; while DPI has no meaning in the video world, it often has significant meaning in scanning (and, of course, printing). If your scanning program only allows image size adjustments in DPI, then you'll have to adapt to that ... keeping in mind that the scanner's DPI setting directly relates to pixel resolution. And it is pixel resolution (not DPI) that will make all the difference in the world for images used in video. You can test this yourself by scanning an image at 1000 x 1200 @ 72 DPI and again at 1000 x 1200 at 300 DPI. They will look identical on TV or projection as long as the pixel resolution remains the same.
    As an example, my Epson scanning software allows me to adjust image size by DPI or pixel resolution. Wanting to maintain the correct aspect ratio for the image area that I'm scanning, I adjust the DPI setting which in turn adjusts the pixel resolution automatically. But it doesn't work the other way around; if I adjust the pixel resolution settings manually, the DPI setting does not change. Your software may vary.
    As Jim Cookman suggested, a scan setting of 300 DPI works well for most images ranging from 3 x 5 to 4 x 6 (typical snapshot size) in a DV Sequence. I may scan smaller images at 400 or 600 DPI and larger images (8 x 10 and up) at 150 DPI. Other size images fall in between those numbers. But I'm constantly watching the pixel resolution numbers to make sure I'm getting what I'll need to support the animation I intend to apply to the images once in FCP. Also bear in mind that I don't always scan the entire image. I only scan the area of an image that I intend to use in my program.
    So the answer is that it all depends on your scanner's software and how far you plan to push into an image once in FCP. Do a few experiments ... you're a bright fellow so it shouldn't take long for you to find the formula that suits your purposes.
    I haven't edited an HD Sequence using images yet, so I cannot offer definitive pixel resolutions for you there.
    On to your specific questions:
    1. See above. There is no one correct answer It all depends on what you intend to do with the image once it's in FCP. If you only plan to push in about 10%, you won't need much higher resolution than the equivalent of your FCP Sequence resolution. If you plan to push in further, you'll need a higher resolution to support that move.
    2. I've been doing these for many years (SD Sequences only) and I've never loaded them into Photoshop first. I import the entire folder into FCP and drop it on the Timeline so I can see what the images look like on TV; unless your program is for CD-ROM or web delivery, that's where it counts. When you place them on the Timeline, FCP will automatically scale to your Sequence settings and pixel aspect ratio. If I see that some of them need adjustment using an external editor such as Photoshop, then and only then do I use that program. And by the way, if you have a vertical image and a 16 x 9 aspect ratio in FCP, how do you propose to crop it to fit? Perhaps you meant another term instead of "crop."
    3. If it's a print, it won't matter what size they supply because you'll control the image size when scanning. If it's a file ... once again, the size (pixel resolution) depends on what you intend to do with the image once in FCP.
    I really don't want to know WHY any of this is the way it is. I just want someone to say: "Do this; do this; and then do this."<<</div>
    With that attitude, how did you ever earn a PhD from an Ivy League university? But if that is truly all you want, you might consider hiring an experienced editor to do it for you.

  • Images in browsers all screwed up

    Since installing the 2008-005 OS X security update last week (via System Preferences Software Update), periodic images in my web browsers (Safari and Firefox) are all messed up (color streaks, pixellation, etc.). When a page with a messed up image is refreshed, the messed up photos usually get messed up in a different way. Sometimes they are fine. When I download a messed up image, it's saved messed up. It seems quite random and happens to JPEG, GIF, as well as an occasional video. I have Virtual PC installed on my computer as well and Internet Explorer and Firefox display images fine when running Windows XP. This problem only seems to occur in web browsers. Images outside of Safari and Firefox for the Mac look fine. And it's only some images in the browsers. Ideas?

    HI kit,
    Hopefully this is an easy fix. First, when using browsers, their caches need to be emptied and their preference files can become corrupted.
    Launch Safari. From the Menu click Safari/Empty Cache. Same with Firefox.
    Now, close all browsers. Locate these files: com.apple.safari.plist and com.mozilla.plist <-- that last file name maybe not be exact but I'm close.
    They are located here; /Users/YourName/Library/Preferences: Open the Preferences folder, locate those files, drag those files to the Trash and reboot. It's ok to trash pref files as your Mac will create new ones.
    Also, if you haven't got one a good disk utility that can clean out old cache files for you... Onyx is great, it's free and available here for Tiger: http://www.titanium.free.fr/pgs2/english/onyx_tiger.html Download and install Onyx. Use the Maintenance and Cleaning scripts once a week to help keep your Mac happy.
