Apple TV displaying image in 256 colors

I've set my AppleTV up to my 1080p LCD television via HDMI. The sound works perfectly and the image displays, but it is only showing 256 colors and the image is dithered - imagine saving a photograph as a GIF image and that's what the AppleTV display looks like. This applies to everything - the menus, photographs, movies, videos, YouTube, etc. When I do a factory restore it even applies to the installation menus. It seems to be a hardware issue, but I'm not quite sure what it could be. I've tried to connect to the other HDMI port with the same issue. I've tried different HDMI cables with the same issue. Other HDMI devices, such as the Playstation 3 work perfectly. I've tried all the available resolutions in the AppleTV settings. I've tried the various HDMI settings (auto, rgb, etc). I've got the latest software updates. I've done 2 factory restores. Have shut down the AppleTV to let it cool off and still the same problem. Any ideas what else I could try?

Unfortunately, there are no Apple Stores where I live (I purchased the AppleTV via the AppleStore online). I've since found that if I turn the tv off, turn the AppleTV off, turn on the TV and then plug the AppleTV back in, it works. It seems that would indicate there is no hardware issue but, rather, a problem with syncing of the HDMI signal. Since none of my other HDMI devices have this problem, I have to assume it's an AppleTV issue. Hopefully a future software update will fix it.

  • Displays stuck at 256 colors

    My elderly parents' iBook is (as far as I can tell---they are 4000 miles away in England) stuck displaying in 256 colo(u)rs. They can set the Displays panel to millions (or thousands) of colors in the popup menu, but it makes no difference to the display. I've got them to restart etc, and now I'm contemplating deleting the "com.apple.preference.displays..." in their user Library.
    My question: does seem a reasonable next step?
    If not, any other suggestions?
    TIA

    I had a very similar problem and honestly just stumbled on this solution.
    Have your parents hold down the Control, Option, & Apple keys at the same time and press the < key. I have no clue why but on my iBook pressing that increases the resolution and pressing the > decreases it. I have no clue how my resolution got decreased (I personally blame one of my roomates). But I would try this quick fix and see if it helps. let me know if it works for you too! good luck
    ALSO:
    They can also try to use the ColorSync Utility in the Utilities folder.
    There is an excellent Profile first aid option that could also help you out.

  • TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

    My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

    Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
    Long shot but...
    I wonder if it's a variation of this, of which I've seen many different symptoms...
    Resolution
    Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
    If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
    Additional Information
    This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
        1.    Open System Preferences > Security & Privacy > General.  Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
        2.    Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
    Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

  • I lecture for a living. My old G4 connected to LCD projector worked great.  My new MacBookPro connected to LCD projector - the displayed images look as if I used "pastel colors" instead of bright colors.  Help !

    I lecture for a living. My old G4 connected to LCD projector worked great; image displayed on computer monitor is same as that projected by LCD. However my new MacBookPro connected to the LCD projector displays washed out images, as if I designed my Keynote lecture using pastel colors. Also my black & white x-ray images are blue & white. Help !

    Did the Apple Genius explain to you why it did not work or even if it's possible?

  • How can I use IMGPLOT to display a 12-bit image in false color?

    I want to use IMGPLOT to display a 12-bit image in false color employing VC++ 7.0 . Actually it is stilla grey level. The only difference is to customize a new palette. I guess Ni should have a API for me change the palette. I donot want to convert my image into color image since its processing speed is slow.
    Any people has the silimar experience to do this?
    Thanks a lot in advance!
    zmt

    Hi Bruce Ammons,
    Thank you very much for your answer. I still need your clear instruction.
    I can directly display 12 bit image in 256 grey level just using IMGPLOT function without any mapping operation. That is because IMGPLOT directly supports to draw a 12 bit image through IMGPLOT_MONO_12 flag.
    IMGPLOT prototype is imgPlot(GUIHNDL window, void* buffer, uInt32 leftBufOffset, uInt32 topBufOffset, uInt32 xsize, uInt32 ysize, uInt32 xpos, uInt32 ypos, uInt32 flags=IMGPLOT_MONO_12 ).
    Hence I just need a C++ function to change the palette. I believe that IMGPLOT automatically does the 12bit to 8 bit mapping for me. What I need to do is just to change the palette. The question is which NI'S API can change the palette and work well with IMGPLOT. Or I have
    to use IMGPLOTDC and change the palette in the selected DC by myself.
    Your great help is much appreicated!

  • Does Flex support 256 color displays?

    Hi all,
    Does Flex / Flash officially support 256-color displays? I
    can't get the Image control to display any images at all when the
    display is set to 256 colors.
    I've tried PNG, GIF, and JPEG images with monochrome, 16
    color, 256 color, and 24-bit palletes (in every combination the
    formats allow). They *all* work fine if the display is set to
    15-bit color or higher, but *none* of them work if the display is
    set to 256 colors. I would have thought at the very least that the
    Flash player could show a monochrome image on a 256 color display
    Does anyone know if this is a limit in the Flex control, or
    the underlying Flash controls? Could I solve it by using some Flash
    control directly?
    FYI, this the problem exists on both machines that I have
    tested so far. Both using Windows 2000, with both IE7 and FF1.5.
    Any ideas? Thanks!
    Paul

    OK, so this definately looks like a bug in Flex / Flash when
    running on 256 color displays.
    Really simple Flex projects that contain nothing but images
    like:
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="
    http://www.adobe.com/2006/mxml"
    layout="vertical">
    <mx:Image source="
    http://domain/image1.gif"
    />
    <mx:Image source="
    http://domain/image2.jpg"
    />
    <mx:Image source="
    http://domain/image3.png"
    />
    </mx:Application>
    Don't show anything at all, but if you throw in a few images
    via a Text control such as:
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="
    http://www.adobe.com/2006/mxml"
    layout="vertical">
    <mx:Text width="450" height="75"><mx:htmlText>
    <img src="
    http://domain/image1.gif"
    />
    </mx:htmlText></mx:Text>
    <mx:Text width="450" height="75"><mx:htmlText>
    <img src="
    http://domain/image2.jpg"
    />
    </mx:htmlText></mx:Text>
    <mx:Text width="450" height="75"><mx:htmlText>
    <img src ="
    http://domain/image3.png"
    />
    </mx:htmlText></mx:Text>
    <mx:Text width="450" height="75"><mx:htmlText>
    <img src="
    http://domain/image1.gif"
    />
    </mx:htmlText></mx:Text>
    <mx:Text width="450" height="75"><mx:htmlText>
    <img src="
    http://domain/image2.jpg"
    />
    </mx:htmlText></mx:Text>
    <mx:Text width="450" height="75"><mx:htmlText>
    <img src="
    http://domain/image3.png"
    />
    </mx:htmlText></mx:Text>
    <mx:Image source="
    http://domain/image1.gif"
    />
    <mx:Image source="
    http://domain/image2.jpg"
    />
    <mx:Image source="
    http://domain/image3.png"
    />
    </mx:Application>
    Then all of the images will appear - all of those embedded
    into the Text controls, as well as those embedded into the Image
    controls. Note, it seems that there needs to be "significantly"
    more Text controls than Image controls for this to work... but I
    haven't really narrowed that down.
    Also, when the Text controls are not used, it seems that
    popping up Alert boxes cause the images to display correctly until
    the dialog box is dismissed, and then the Image controls disappear
    again!
    Finally, I've found that I can get the Image control to work
    reliably (so far) by itself, if I simply set the height or width to
    be at least one pixel less than (not greater than) the real image.
    So, for example, my image is 450 pixels wide, by 75 pixels
    high. So, of the following four Image controls, only the last one
    works!
    <mx:Image source="
    http://domain/image1.gif"
    />
    <mx:Image width="450" height="75" source="
    http://domain/image1.gif"
    />
    <mx:Image width="451" height="75" source="
    http://domain/image1.gif"
    />
    <mx:Image width="449" height="75" source="
    http://domain/image1.gif"
    />
    Once again, all of these behaviours only occur when the
    display is set to a 256 color mode. Everything works as expected on
    15bit+ color modes.
    So, I guess I should file a bug report now?
    Paul.

  • 23" Apple Cinema Display and accurate color?

    I use a dual 2.3GHz Power Mac G5 along with a 23" Apple Cinema Display fro graphic design work. I used to use a Pantone Color calibration device when I was using third-party monitors with my Macs. Now that I have the Cinema Display, I haven't bothered to calibrate this wonderful monitor. I had heard that using Apple's displays with their own computers would display the most accurate color possible without calibration. I haven't changed the color settings in my Adobe products, and I'm not seeing any significant issues with my color outputs. Any advice on this subject is appreciated.

    If the display uses the Apple Display Connector (ADC)
    <http://upload.wikimedia.org/wikipedia/commons/thumb/0/09/AppleDisplayConnector.j pg/800px-AppleDisplayConnector.jpg>
    you will need a DVI to ADC adapter.

  • OS X Mountain Lion - Apple mail not displaying images

    Ever since upgrading to OS X Mountain Lion a few weeks ago, Apple Mail no longer displays images in emails.  I have downloaded and installed the latest Java RTE [it was out of date] - that didn't fix it.  I have tried to reset my Java preferences to their defaults - that didn't fix it.
    Is anyone else experiencing this issue?  If so, have you found a solution?
    Thanks in advance!

    I have exactly the same problem although its not for every email. My email provider is gmail. If I forward an email to someone else, they have no problem viewing the images. Very annoying. Checked with my gmail account and these are not classed as spam.

  • Does 23" Apple Cinema Display support sAdobe Color Profile?

    I take it back. NEC sell a monitor that acheives 107% of the Adobe Color Space.

  • Is Aperture displaying images with a modified color temp. or gamma?

    I am brand new to Aperture and after importing some scans from black and white negatives, I notice that the same images when viewed in Preview or Photoshop appear brighter and perhaps cooler (but it is hard to tell with black and white images).
    I am just trying to discover why Aperture displays images a little differently than other applications.
    Thanks in advance.
    D

    the same images when viewed in Preview or Photoshop
    Comparison across applications is meaningful if and only if the image has the selfsame source ICC colour space profile. Begin by checking that the image has an embedded source ICC colour space profile. There are lots of ways, either run one the ColorSync AppleScript that extracts the embedded profile, or open the image in Apple Preview and check Tools > Get Info > Summary: ColorSync Profile, or open the image in the Apple ColorSync Utility, or open the image in Adobe Photoshop (which will describe an image without an embedded source ICC colour space profile as 'Untagged RGB', 'Untagged Gray' or 'Untagged CMYK'). If instead you open an image without an embedded source ICC colour space profile in a series of side-by-side application windows, these applications will assign an assumed source ICC colour space profile and the sources they assign may not be the same. In order to configure a conversion you have to have a source and a destination: no source, no colour managed conversion, so a source has sometimes to be assigned.
    Hope this helps,
    Henrik

  • Display problems after going from millions to 256 colors

    In order to improve the speed of the display, I changed the screen color depth from millions to 256 colors. However since then the display in ARD is useless (it doesn't seem to know that the depth changed so you got 4 garbled up displays next to each other (like he is still expecting 4 times as much information.
    Restarting ARD (and restarting the ARD services on the server) don't seem to help. Any ideas how to get this up and running.

    Me too. Interested in resolution on this.

  • Calibrating Apple Cinema Display for Video Editing

    What's the procedure to calibrate an Apple Cinema Display for editing in FCP (editing and preliminary color grading)?
    My camcorder can produce color bars, but I can't hook it up directly to the monitor. Shall I record color bars and use the recorded clip to calibrate? What's the procedure regarding calibration?
    Thanks!

    The need to "calibrate" a display for video "editing" is a complete fallacy. There is no need to have accurate images when plopping pictures and graphics next to each other to create a story in a linear fashion. For accuracy you need a dedicated input/output device with a display that represents your intended delivery; projection, broadcast, whatever. If your intended delivery is web or phone only, well, it's a total rodeo where the word "consistency" has no meaning at all.
    The MXO, it puts a look up table on a computer monitor and then does some other electronic mumbo jumbo to simulate interlacing and other tv junk. I call it lipstick on a pig, others here will give it high marks.
    The only real constant is that if you want to play in the world of "hd", the costs are bigger than in "sd" and is the return on investment worth it?

  • New iMac display problem(?) - weird colors and grain

    Hello,
    I'm a fresh mac user, made the switch this monday (August 27th) when my 24" iMac 2.4GHz C2D arrived. After using it for a while, I noticed a handful of dead pixels, and a semi-bright green stuck one. I thought I'd wait and see how disturbing I would find them before raising an issue about them.
    Well, yesterday I decided to make my first backup of the whole system to my external 500GB Lacie drive (connected with FW800) using Super Duper!, which to my understanding is a reasonably sturdy and reliable backup application.
    During the first backup iteration I started to notice some alterations in color in the top middle part of the display. I then returned to whatever I was doing (not on the mac, I had no other applications running, just Super Duper!), and after a while took another look at the display. The weird colored area had expanded, and the whole display had become somewhat grainy. Also, the backup process had slowed down quite a bit (from ~30MB/s to ~7-8MB/s).
    So I cancelled the backup operation and logged out and back in again. No change. Then I restarted the whole system, which booted just fine, with none of the aforementioned problems. Even the second backup iteration went without problems.
    Still, it's a new (and with my budget, quite expensive) computer, and if I get this kind of problem during the first week, I cannot continue using it happily in the fear of these problems reoccurring time and again.
    I took a couple of pictures of this, one during and one after the problem. The quality of these are quite lousy, they're taken with my Nokia 9500 Communicator.
    During the problem:
    http://iki.fi/aita/imac/01notok.jpg
    After rebooting:
    http://iki.fi/aita/imac/02_ok.jpg
    The images are taken in the same light conditions, but from slightly different viewing points. Note: The first image does not present reflections, it's how the screen looked (actually, in real life it looked somewhat worse)
    What do you think?
    Could this be a driver related issue or have I received bad hardware?
    My drivers and Apple software should be up to date (at least OS X informs me that everything is, and I haven't found newer graphics drivers anywhere).
    If anyone has had the same or related problems or know how I should proceed with this matter, I would be grateful.
    Thank you in advance!

    So far the only fix suggested has been to call apple and get a replacement. I'm still.....still waiting for mine to make it slowly across the ocean from China, so I don't know how the new one is working. I'd call Apple and request a new one.

  • Used Apple Studio Display, Possibly Ruined

    Hello all,
    I purchased a used Apple Studio Display a few days ago and thought nothing of it at the time (I was picking up some used Macs for friends, and it was an afterthought). I figured, what the h*ll.
    So anyway, I finally hooked it up, and was very impressed with the color calibration and overall usefulness of the monitor. The problem was it was very dirty and covered with scratches.
    So, not knowing any better, I proceeded to use some glass cleaner on it, and this got a lot of black residue off the screen, which made things look noticeably cleaner. The bad news was that this was a lot of work, and I was looking for a more "quick and dirty" (poor choice of words, I suppose) method of getting it cleaned up. So I pulled out the "Goo Gone," a commercial product that smells a bit like oranges but which also has some petroleum distillates in it.
    Anyway, long story short: Although the window cleaner and the craptastic miracle cleaner did a bang-up job insofar as the removal of the black matter, there are a few areas of the screen where I was a little too vigorous and have buffed the shine away, leaving a blurred image underneath. Who knew that the screen had a protective plastic coating? Not me, I suppose.
    So I've googled around for some kits to repair the mistake I have made, and I'm coming up empty. I see multitudinous products for cleaning the monitor, and of course I wish I had found them before I endeavored to clean this monitor (it was disgusting, I tell you! Even with the blurring, it's still an improvement!). I still can't find a product to make this puppy shine like it's supposed to.
    There remain a few noticeable scratches on the monitor, and of course I would like to buff those out if possible, but most importantly, I'd like to be able to get back the clarity I thought I was heading for (before I cleaned a little too hard!).
    Responses chiding me for my overzealous cleaning behavior are discouraged, as I am primarily interested in climbing out of the hole I'm in, not in getting shoved further down it.
    Thanks in advance,
    Art

    Well, I'm going to go ahead and answer my own question.
    I attempted to take apart the monitor to take out the smudged glare screen. I was unsuccessful; it's glued directly to the glass in such a way that its removal would have made things much worse.
    When I put it all back together, the monitor no longer worked!
    Oh well, easy come, easy go.
