Can't read iMac display

My imac display is unreadable. Everything looks pixelated and blurry with the resolution set to 1680X1050. It has the Radeon X1600. Tried font smoothing and changing the resolution but it didn't work. Also hooked up a second monitor and the image looked perfect on that one. When you zoom in on the imac its readable, but still does not look up to par. Any help would be greatly appreciated.

Try Resetting the PRAM
If that doesn't make a difference, might be a good idea to run the Apple Hardware Test

  • My printer menu is no longer displaying in English. I can't read the display to try to troubleshoot

    My boss' printer HP Color LaserJet CP2025 - menu no longer displays in English. I can't read the display to troubleshoot or reset. Is there another way to change the setting?

    I have not verified these steps, but this is what I located:
    A. To change the display language back to English, please perform the following steps:
    1. Press the right arrow 2 times, press the OK button (you should be in the System Setup menu).
    2. Press the OK button again (you should be in Language). 
    3. Press the right arrow until you see something that may be English, press OK button. The menu is a continuous loop, so if you miss it the first time the option will return.

  • Can I use iMac display as an external monitor with a pc?

    I have a Windows laptop with VGA output. Can I connect this laptop's VGA output to mini display port of my 27" iMac?

    This can't be done. VGA is an audio signal and there are no converters to turn it into a digital Display Port (DP) or Mini Display Port (MDP) signal. DVI and HDMI are digital signals (with HDMI having audio and a different physical connector) that can be converted into an MDP signal, but doing so requires an expensive converter or an even more expensive converter and scaler if you want to get full resolution on the target display. The cheaper but perhaps more complicated alternative is to replace your PC video card with a DP/MDP card after which you should be able to drive the 27" iMac display without any converter. Apple didn't include DVI/HDMI input capability in the 27" iMac because that would have required additional circuitry that would have raised the price substantially.

  • Can't sleep iMac display with Quicktime Broadcaster

    When I run Quicktime Broadcaster on my iMac, the computer's display will not sleep. I clearly don't want the monitor on 24 hours a day. I can briefly force the display to sleep with hot corners set to sleep the display, but it will wake within a minute or so.
    If I quit Quicktime Broadcaster the display will sleep just fine. Also, I don't have to actually broadcast anything for this to happen, just running does it, as will running QTBroadcaster from the command line via "broadcasterctl."
    Any ideas?

  • How can I read and display data with OR without recording at the same time?

    Hi all,
      This forum has been of much help to me, but I have a rather specific question I can't seem to find an answer to.  I am new to LabView, educating myself with tutorials, trial and error, and this forum. 
      Attached is what I have so far.  I would like to read data (three voltages) and write it to an excel file.  As written below, it will do nothing until I click the "Record" button, when it then takes data, displays it on the gauges and waveform chart, and writes it to a file.  What I would like it to do is display the data at all times, and record when I click the record button (while still displaying data being read).  I have tried to do this by moving the DAQ Assistant VI, gauges, and waveform graph outside of the loops, but when I do this, it will read until I press record, and then it simply records whatever value it's stuck on.  Sorry for the long post, thanks for any help.

    Record and Write to File 2.vi ‏332 KB

    Sorry, I don't have any DAQ installed, so I won't comment on the DAQ parts.
    First of all, Your VI will do nothing until you (1) first set the record button to ON  and (2) press the start button in the tool bar. It almost seems that you are using the "continuous run" button. (Don't! That's not its purpose. Basically, it automatically restarts the program whenever it finishes). A toplevel VI should never stop during normal operation, so place a big while loop around all code and create a wait state that does nothing until you tell it to acquire.
    You don't need the inner while loop, simply place your code inside the big while loop (and accumulate your array data in an initialized shift register if really needed. Currently you do at the inner loop boundary for some reason). You have a big problem that the array can grow without bounds unless you clear the accumulated data once in a while or place it in a FIFO buffer of limited size. If you let ot grow forever like you do now, the program might run out of resources at one point in the future.
    Since you are appending to your file, maybe yo don't need any shift register, just use the data points of the current iteration. Place your save operations in a case structure and keep appending the new data to your file only if the case is true.
    It is also very inefficient to use highlevel file IO here,because each instance opens and closes the file. I recommend to open the file once outside the loop, then use low level IO to append, and close the file once the big loop is done.

    Hello,
      The ATR file is one of three files that are outputed as a result of a test that is performed with UnHoltz Dickie test equipment  that is used in a vibration lab. Does this help answer the question is there are any viewers?

  • I am planning on recycling an old iMac and Powerbook.  However, the display on the iMac is so messed up I can't read anything and the Powerbook is unusable (no power) so what do I do about erasing the hardrives for security?

    I've been reading up on how to clean your hard drive so personal information can't be accessed, but if you can't get to your hard drive to clean it up, what are you supposed to do?  My town is offering an electronics recycling and I was hoping to drop off my old iMac and Powerbook.   I can turn the iMac on, but the display is really bad and almost unreadable.  The Powerbook is completely dead.   Any suggestions?  Thanks.

    Since both computers have operational problems, I'd suggest removing the hard drives from them.  That way, you'll have possession of the drives and their data.  Considering their age, I doubt that the recycling program will attempt to repair these computers for donation to needy parties, but if you thought so, you could buy a $15 adapter that would let you connect the bare drive to a USB port on your functioning computer.  Once connected, you could erase the drives and reinstall them.  You didn't indicate which iMac you have, but if it's a G3 model, this Macworld article has illustrated directions for hardware upgrades, which would show you how to remove the hard drive.  If your iMac is a G3 (400 MHz or faster) with the additional VGA port concealed under the plastic door on the rear of its underside, you could connect a VGA display and attempt setting up video mirroring.  Once done, you could wipe the drive, while using the connected display to navigate through the procedure.  This would eliminate the need to open the bottom of the housing, to access the hard drive for removal.  As for the PowerBook, you could post a topic in its specific Forum (depending on the model) and request directions for hard drive removal.  Post back as to your preferred option, if you have any questions regarding it.

  • HT3924 can i use iMac keyboard and mouse when it is in Target Display Mode and attached to my MBP?

    I can attach my iMac to my MBP via thunderbolt and run it in Target Display Mode, so that itsimply becomes a screen attached to my MBP.
    What I really want is for the keyboard and mouse of my iMac to also operate as if they were attached to my MBP, but I cant seem to achieve this.
    Is it possible?

    Its a wireless mouse and keyboard - dont think I can re-pair the keyboard to MBP since I need it talking to the iMac to enable and disable TDM?
    I expected TDM to natively pass through the mouse and keyboard to the MBP, since that is the obvious user requirement. But this does not happen.
    So I guess I want a workaround so my iMac keyboard and mouse can drive my MBP while attached via Thunderbolt cable in TDM mode.

    I tightened all HD screws and it didn't help. With the machine running and side of the case off, I physically stopped both the video card fan and the front case fan with my finger for a couple seconds and the noise continued. I also took all hard drives out one by one and rebooted each time. Again, the noise continued until I took out the Mac HD in Bay 1, rebooted, and I had a very quiet, silent machine. The issue is the hard drive in bay 1 that shipped with the computer, it's without a doubt causing the hum/woosh sound. I still need to know if I can safely swap the Mac HD from bay 1 to bay 4 without any issues to the operating system. I would like to try that to see if it dampens the noise but I also want to make sure this swap won't screw up my machine at all.

  • How can I operate  multi displays on my Imac 21.5 quad core 2.5 and have each display function independently?

    how can I operate  multi displays on my Imac 21.5 quad core 2.5 using Lion and have each display function independently?

    Below are some converters/adapters to look at.  If these look like they may work:
    USB 2.0 to HDMI Audio Video 1080P Adapter for Windows and Macbook
    Matrox DualHead2Go D2G-A2D-IF (or look here)
    These should allow you to run multiple displays in extended display mode.  Note that these use HDMI as an output so you would need some additional adapter to conver HDMI to whatever your displays require.  Of course these suggestions are all academic if such an adapter doesn't exist.
    Update:
    I just reread your last post and I am confused.  Is it only your TV that you are trying to run in extended display mode?  I thought you wanted more than two displays.  If only  the TV it should just work if you are not using mirrored displays.  Your Displays Arrangement tab should show both your main screen (one with the little whith menu bar) and the TV.  Set the proper resolution and refresh rate for the TV using it's Displays preference window.  That is all you need to basically do (ignoring overscan/underscan problems).
    Note, if you are using Lion then I have heard that when using full screen mode in Lion additional screens show nothing.

  • IMac display going bad, can I connect a MBP to it in some way so that I can transfer files?

    I need to get some files off of an old iMac. This iMac is model that has the white half-round base that looks sort of like a lamp.
    (It looks like this, not sure if its this exact model or a newer one: http://www.everymac.com/systems/apple/imac/specs/imac_800_17_fp.html)
    The display is very garbled, I can only read about half of the scene and this part that I can read is distorted.
    I've got a 2006 MBP and a new 2012 MBP that I can use to connect to it. Can I connect either of these in some way (firewire or ethernet or some other way) so that I can see it's HD on my MBP and copy the files over?
    Thanks in advance to all who answer...  And if there is a better forum to ask this question in, somebody please let me know.

    The older MBP I have has firewire 400. It's a core 2 duo, I think 2006 was the year it was made.
    So, I should be able to connect my older MBP and the iMac in target disk mode and see the iMac's HD on my MBP's screen. This is what I hope can be done becuase I can't really see much on the iMac's screen.
    Thanks for the TDM link and the UltraATA to USB adapter suggestion.

  • Some times my new iMacs display start flickring when I starts playing a game. I am very annoyed. I have bought it only 1 month ago. What can I do?

    Some times my new iMacs display start flickring when I starts playing a game. I am very annoyed. I have bought it only 1 month ago. What can I do?

    A flickering display sounds to me like a hardware problem.  Or does this only happen with a specific game? Of course your machine is still under warrantee so you could take advantge of it if you have a local apple store.

    How do you read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine?
    I tried using a DAQ Assistant but the CAN port is not included as one of the supported physical channels even though all its drivers are upto date.
    Please help..
    Thanks.
    Solved!

    Attached herewith is a print screen of what is showing on MAX
    The CAN ports are on NI PXI-8461
    Hopefully that clarrifies something.

  • I bought a used PowerMacPC G5. I can burn and read DVDs, but I can't read or burn CDs. The CDs are not even recognized. After the drive searches for a while, the CD is ejected without any error messages. The CDs work okay on my iMac.

    I bought a used PowerMacPC G5. I can burn and read DVDs, but I can't read or burn CDs. The CDs are not even recognized. After the drive searches for a while, the CD is ejected without any error messages. The CDs work okay on my iMac.
    I am running Mac OSX 10.4.11. According to the System profiler the CD/DVD drive is a "PioneerDVD-RWDVR-112D." When I compare the information under this heading, the only unusual difference from my iMac is that the G5 reads "Burn Support: Yes (Unsupported)." My iMac reads "Burn Support: Yes (Apple Shipping Drive)."
    Under the System Preferences the options are set to "Ask what to do" when a blank CD or DVD is inserted. Music CD set to open iTunes, Picture CD set to open iPhoto, Video DVD set to open DVD player.
    Do you have any suggestions?
    Thanks, Jack
