Gray (233,233,233) region trembles on DELL U2412M

This is weired but really happening. I just bought DELL U2412 monitor, and used DVI and DVI adapter. Now when I launch Eclipse, the background of the window is gray (RGB 233,233,233) and it trembles, as if it is an old fluroscent light. It is not the problem of Eclipse because the same color trembles on wallpaper, too.
Now with the exact same hardware, when I booted up to Windows 7, the same color did not make the region tremble, so it is not a faulty hardware.
Are there anyone having the same issue with DELL's monitors?
And by the way, do you know how to change the background color of Eclipse? Trembling gray is really annoying.

If you use an open source video driver, I suggest you enable Early Start (Note: this is only for open source video drivers).

Also, which bootloader do you use? Post your syslinux.cfg or /etc/default/grub (if you automatically regenerate a grub.cfg), because maybe you skipped something from the plymouth documentation.

  • Dell U2412M as an external display for my MacBook Pro mid 2008, the clarity of fonts are absolutely unimpressive.  The settings do not detect the Dell U2412M (which is grayed out), are there any drivers that need to be installed ?

    I have posted this annoying Robles to bugreport.apple.com. Hope I can get locution (although Apple normally will not respond):
    On a software name Appfresh, it alerted me to update my MBPr 15 inches running latest OSX 10.8.2, with Chinese Word List Update 1.2. When I clicked on Software Pdate, app Store return No update available.
    My system have Chinese Word List Update 1.0 installed, and on October 5, 2012, Chinese Word List Update 1.1 was released by Apple, as alerted through AppFresh. However, this update never get updated on m system. I have to manually download chinesewordlistupdate.pkg from reviews.cnet.com/macfixit and install it manually. By doing so, I have Chinese Word List Update 1.1 on my system.
    The same problem occurred again today on November 5, 2012, where Chinese Word List Update is released by Apple. again, it fail to update from Software Update menu.
    Can you please:
    1. Explain why this problem occurred. This is so annoying.
    2. Advise me how can I get this Chinese Word List Date to update to version 1.2. Can you please send me the chinesewordlistupdate.pkg for version 1,2 so that I can manually install it on my system?
    3. How can I prevent similar problem with he subsequent version?
    Why Apple don't make this update standard as other update?
    Support please. Thank for response in advance

  • Startup Conflict: Mac Air & Dell U2412M Monitor?

    I've got a Dell U2412M monitor connected to my Macbook Air 11", running OS 10.8.5. But more than occasionally, the Air won't launch; I get the gray screen and the spinning beach ball. By unplugging the peripherals (the display port-to-monitor, the USB cable that runs from the computer to the monitor, and a USB hub), I seem to have isolated the problem as the USB cable that runs from the computer to the monitor. Anyone know why this happens, and how I can resolve the conflict?
    I can launch by unplugging the peripherals, then plugging them in after the Air boots. But I'd like to get it working normally, if possible. Many thanks in advance for your help.

  • W520 with Mini Dock Plus Series 3 won't detect Dell U2412M Monitor

    I have a W520 Thinkpad with a Mini Dock Plus Series 3 with USB 3.0.
    Until this morning, I was able to use it with my two external monitors connected via DVI to the Mini Dock.
    The two monitors I have are:
    Acer V243H
    Dell U2412M
    The Acer works fine regardless of which DVI port I plug it into.
    The Dell refuses to work on either port.
    Again, both monitors were working fine as of yesterday.
    Any ideas on what might have caused this or what I can do to fix it?

    I have the same problem with the minidock and display port monitors. It will not recognize them at all on power up. If I then put the w520 to sleep and wake it up a few times, it will then recognize them and allow me to use them as "projectors".
    Before I upgraded the BIOS and nVidia drivers, it would always recognize one of the two, and I used to have to pull the cable out and in again on the second. Now this technique doesnt work - sleep wake is the only work around.

  • Problems connecting a dell u2412m to a macbook pro?

    I connected my new MBP to a Dell U2412M that I used on my PC. I used the VGA port on the Display and adapted it to the MBP via DVi port. The display seems connected to the MBP as the cursor works the only pic I get is the screen saver. Any one else have a similar problem?

    If you are getting a picture of any kind, your display is working as designed.
    The default is to add the second display to an "Extended desktop", and allow the mouse to move across both displays, dragging a window if you wish. Everything in the Arrange pane is moveable, so the displays can be moved in any contiguous orientation to each other and the menuBar can be dragged to either display as well.

  • How do I connect my MacBookPro to my Dell U2412M 24" monitor?

    How di I connect my MacBookPro to my new Dell U2412M 24" monitor?

    If your MacBook Pro has a Mini DisplayPort or Thunderbolt port, use a Mini DisplayPort to DisplayPort cable.  If not, use a DVI cable.

  • My Dell U2412M monitor looks awful on OS X

    I bought my first Mac (Mini 2014) and attached to my Dell U2412M external monitor and the graphics looks awful, all blurry and pixelated.
    For the avoidance of any doubt:
    1) Mini is connected to minitor via miniDP to DP cable
    2) Color is correctly set to RGB
    3) Resolution is on the right setting
    4) Pictures look fine, the problem is just with the font rendering, in any application
    5) Have tried turning LCD font smoothing on and off but does not really make a big difference
    Any other setting I can try? Is Mac really this bad at handling fonts? I use the same monitor on a windows laptop and font is crystal clear. It is like looking at a 1024x768 screen while mine is a pretty decent 1920x1200.
    thanks

  • Dell U2412M monitor

    I just purchased the Del U2412M monitor. I have a new Apple MacBook retina 13 inch computer. I connected the monitor with an HDM I to DVI cable. The monitor works but none of the information on my computer is showing up on the monitor. What do you think the issue would be?

    I'm sorry about that. There is an obvious connection because when i open the display icon with "System Pref's" it shows up on both the laptop and monitor but when I access lets say "Safari" or any other program it only comes up on the laptop and is not showing up on the monitor. I ordered a lightning - DVI cable, maybe it's the connection right now the connection is being made with a HDMI - DVI cable. I hope that explains it a little better.

  • Macbook Pro with Retina Display with Dell U2412m external monitor

    I recently purchased the Dell U2412m monitor on Amazon hoping to use it as my external monitor to my Macbook pro 15" with retina display, however, when I finish setting it up, there's a red/pink vertical line showing on my screen. Does anyone know what seems to be the problem and how do I get rid of the line. Is there anything I need to set up on the monitor to make it compatible with MBP with retina?? Thanks in advance.

    I used a mini display port to display port cable and my screen looked fine. My problem was that the USB ports did not work and dealing with Dell customer service was a nightmare.

  • X220 display port not detecting Dell u2412M monitor

    My new Dell U2412 1920x1200 is not recognized by te Lenovo X220 DisplayPort connector. I read that this may be a common problem. Is it so?
    It shows a single monitor when monitor connected through dislay port (og with vga output)

    yes it is. Try to use a displayport to dvi converter to connect to the LCD.

  • Why do purple lines appear when I connect my macbook to my Dell U2412M moniter?

    So I got my Thunderbolt to HDMI cable today and I tried plugging it in. The display comes up clear and then slowly degrades with more and more horizontal purple lines. I've never seen anything like it. The display is basically useless within 30 seconds. I tried rebooting my Macbook, restarted my monitor, I tried the adapter with a couple of other monitors and TVs and it worked fine. I tried my monitor with another macbook and my xbox but the HDMI worked. I have no idea what to do anymore.

    Hi Jake,
    It's impossible to know without troubleshooting, but it sure sounds like a bad adapter or cable.

  • Unable to edit an Audio Region (just want to change gain)

    Hello,
    In a particular audio region I am unable to change gain in that the "Change Gain" command (as well as all the other functions) are Grayed-out FOR THIS REGION. I am in Sample Editor>Functions>Change Gain.
    There are over 200 audio regions in this file. Most of them have NONE of the edit functions grayed-out.
    A few other regions have all the edit functions Grayed-out except for Change gain.
    Almost all of the audio regions are from apple loops. I have not edited any of the regions except for some regions ending points, and volume automation added.
    Why would this one particular audio region ("Country Night") by un-editable?
    (NONE of the tracks are locked.)
    please help

    Is it a file in .caf format? If so, note that compressed Audio formats can't be edited destructively. Convert to aiff/wav before.
    Btw, there is a Gain function in the Region Inspector since Logic 9, so there is no need to change the gain in the sample editor anymore.

  • 2014 Mac Mini won't detect Dell monitor on startup

    On a cold start or waking from sleep it is necessary to reset the PRAM in order for the Mini to recognize a Dell P2014H.  Restarts are not a problem.
    This was not an issue with an older MacBook Pro or an Air at the Genius Bar.  I have resolved this by setting preferences to never turn the display off but don't consider this a permanent fix. 
    I'm running 10.10.1 and connected via VGA to a Thunderbolt port.  The monitor is only 7 months old so I'm not inclined to replace it yet or add even more cables to my collection just to find that doesn't fix anything.  In fact when another 2014 Mini was connected to my monitor at the Apple store it had the same problem.
    On the other hand our 2012 Mini has never had issues with a Dell U2412M.   So what's up Apple?

    I just bought a Mac Mini with latest operating system 10.10.1 and had the same problem. I also used a monitor with HDMI cable. I spent 45 minutes on the phone with Apple Care tech but no solutions. I took it back to shop and they tested it but did not have a HDMI cable and used a thunderbolt adapter. It worked fine. Bought a Thunderbolt adapter for HDMI cable and problem solved. Both mouse and keyboard now wake up system. Perhaps a future update will solve this but for now I'm happy.

  • Buying a Dell monitor for my MacBook Pro

    Hey people,
    Sorry for being a newbie with this forums, I don't really know if this question should be posted here, considering I will use the monitor with my rMBP or if I should post this at the peripherals section of the forums.
    Anyway, I'm in doubt between buying a Dell U2412M and the Dell U2414H, but I've seen people saying they had problems with both of them. Basically relating to making the DP ports to work with and sometimes about the amount of colors displayed (some people said the monitors wore not working at 8 bits (16.7m colors) when connected by HDMI and DP, due to the computer recognizing the monitors as TV screens or something like that) and that there is an Issue with the HDMI due to the nVidia graphics card. Also there's an issue with the monitor going to sleep mode and not coming back without re-plugging it.
    My main questions are related to the connectivity (if the mDP works well considering I will use it for both monitors, I'm not thinking about buying converters to use DVI or even using the HDMI port); to the fact that one of the screens is 16:10 and the other is 16:9 (I don't know if that makes much difference, I will use the computer for work (some CAD applications and 3D rendering) and sometimes for photography editing after the renderings). The fact about the USB ports being 2.0 with the 2412M is not an issue at all.
    As I heard both monitors are pretty decent concerning color reproduction, with the 2414H coming calibrated from factory and the 2412M being better if properly calibrated (according to TFT Central).
    And the last question, IF somebody has the 2414H is if it could work as a TV (I would use an outside receiver (such as cable TV and Apple TV) and connect it to the HDMI port, but for that I would need the monitor to put the sound out from the audio connector, anybody know if it works?)
    So, if anybody could give me any information about these monitors I'd be pleased. Or maybe other suggestions I'd be glad (My budget cannot go beyond the price of those Dell)
    Thanks in advance,
    Best regards.

    Yes, if it's a Thunderbolt computer, but you will need to connect another Thunderbolt device (such as a disk drive) between the displays.
