ST2421L, black bands around image suddenly appeared

It is a real headache. Suddenly, without apparent reason, my ST2421L monitor shows black bands around the image of the screen (regardless if it's the desktop computer or a browser or MS Word). Seriously, when I started to work in the morning, everything was normal. I blinked, and then there are black bars. I did some research on the support forums, and it was suggested to install something called AMD Catalyst Suite. When I tried to do, he ran and then the dreaded blue screen appeared. Using Control Panel, I checked to see if Windows was the drivers for the monitor is up-to-date and that they were. I also went through the factory reset via the OSD menu, disconnected power to the monitor and its HDMI cable, etc.. Any suggestions would be greatly appreciated. Thanks in advance!

  • WHY don't images suddenly appear or show in my gmail messages using Firefox 12.0 AND 13.0 but I can see the beautiful in IE9?

    WHY don't pictures suddenly not appear or display in my personal messages gmail using Firefox 12.0 AND 13.0 but I can see the beautiful in IE9? This isn't a problem with the images being seen on Web sites or in emails from various sites like Amazon, Bloomies, etc.. It is a problem with the images, copied and pasted while composing mail in GMAIL and the other Windows Live email accounts, etc. It started suddenly yesterday when I still had version 12.0 Firefox. (there may be a few days, but I hadn't been reading emails too for a few days due to time constraints). This morning I tried to find some fix for this by searhcing constantly through the web and through the forums of Firefox here. I checked my version of Firefox and also check for updates after about 2 hours of research from the forums without success and I was about to just get rid of Firefox 12 because some people were just that frustration with finding no solution, when suddenly, I got a message from Firefox 'urge' Update update me Firefox 13. It was AFTER I had just checked an hour earlier to see if there's an update! I did this update to version 13.0, BUT again, I do not receive emails containing images with these images posted (messages sent from my other e-mail account for myself and also e-mails to a friend - the two images containing). However, I can send and receive your same emails through IE9 in my gmail account and see all of the images of the FINE through IE9. What gives? I am so tired of what's going on. It happened before about a year or two ago, but I do not remember how it was corrected for ever. According to me, it has been resolved by a Firefox patch, and no action on our part. And these 4 + hours of work on that is just crazy. WHO has that kind of time to devote to fix these defects that occur every time updates of Firefox? I can not even find any mention of the same show. Now I'm seriously behind. You talk about time constraints! Anyone else having this problem? Someone at - he found a cure yet?

    Is he missing pictures then make sure you are not block images from certain domains.

    • Check the permissions for the domain in the active tab in "tools > Page Info > Permissions.
    • Check that the images are enabled: Tools > Options > content: [X] loading images automatically
    • Check exceptions in "tools > Options > content: Load Images > Exceptions.
    • See the tab "tools > Page Info > media ' for blocked images (scroll all the images with the cursor key).

    If an image in the list is grayed out and there is a check mark in the box "block Images of..." and remove this mark to unlock the images from this area.

    Make sure that you do not block the images of third parties, the pref permissions.default.images must be 1.

    There are also extensions (Tools > Modules > Extensions) and security software (firewall, antivirus) that can block images.

    Everything which has been written and this last screenshot of yours, there may be an answer. For some unknown reason, the preset of the project were wanton for your source of 1920 x 1080.

    I have a problem with something in firefox, it is quite minor, but still bothers me. Last night suddenly when I right click view image in firefox, they appear centered and on a black background.

    Hello

    1. don't you make changes to your monitor or a computer, after which the issue started?

    I would recommend that you follow these steps and check if the problem persists.

    Step 1:

    Update your display drivers n check if the problem persists.
    http://support.Microsoft.com/kb/283658

    Step 2:

    Test the issue in safe mode and check if the problem persists.

    Step 3:

    Also see the manual of the monitor to check if you need to make changes of configuration on the screen itself.

    If you could post the screenshot, it would be much easier for us to understand what is the exact scenario as.

  • Black border around all the images from my video.

    I'm new to the forum here and am struggling to find an answer to my problem and I was wondering if someone could help me. I use elements adobe first 9 create a photo slideshow.  I have about 90 photos, with several of them and audio text throughout all this.  I don't know very well this program, I used it once to make a video.  When it's over, I burn it to a dvd.  The problem I have is that when I burn it to a dvd and play in my dvd player, the photos are of size reduced and there is a black border around them (all 4 sides).  Do you know what I can do to make it go away?  The last video I had not so I'm not sure what I did with this one.  And I tried to compress images and it changed nothing.

    Thank you very much!

    Lish8,

    If some of the stills are smaller than the size of the frame of the project, you will want to either their scale exactly, if required for the extensions to match, or you want to use the default size of the image scale, but take note: scale to the size of the picture by default dimensionnera only the size of fist to the rider, so if the Ratio of Aspect is off say that Images are in 16:9 and image of the project size is 4:3, you'll still have a few black bars.

    If the Images are close, I would say that you are using the fixed effect > Motion > scale, to increase the scale, so that the scope of the draft framework is filled on all sides. It will be actually reframe the view of the stills to the Aspect Ratio of the size of the image of the project. If you don't harvest like that effective, simply adjust the fixed effect > Motion > Position, to get a better harvest.

    The holds of same for still Images, which are a bit larger - I would manually scaling those to match the project frame size.

    That's why Steve recommends a slightly larger Image, that the size of the frame of the project - it gives you a bit of room for manoeuvre, in the final scale and Position.

    Good luck

  • When turned on my laptop, there is a black border around the screen.

    Original title: screen resolution problem

    Hello

    A few weeks ago, I turned on my laptopn and there was a black border around the screen. I managed to change the screen resolution, but my laptop seems to think that I have a dual monitor? And my resolution is still not like it was before. Obviously this isn't a huge problem, but it's annoying to have to go and change it regularly.

    In addition, given that this has started to happen, I noticed that when I turn on my laptopn, instead of the usual Acer / Windows startup screen, the screen is all black, until the login screen appears. I don't know if this is related or how, once again, this isn't a big deal in the grand scheme of things, but if an update is installed, you do not see the progress it's making!

    I ran a system restore, without success.

    Running Windows 7 on a laptop Acer Aspire. Any suggestions welcome, although I'm not that tech-savvy!

    Thank you

    Hello

    The first thing to check is your theme controls. Go to the control panel and select personalization. When this window opens, go down and select wallpaper. When this window opens go to the lower left corner and make sure that the background that position of the image is set to 'bridge '. Save the changes and return (right click on the name of the theme in the theme dialog box).

    Let me know if this solves the problem for you.

    Kind regards

  • Vista Home Premium boots with black bands on the sides of the screen and features limited after d/l-ing Windows updates

    Hello

    My Dell Inspiron 530 has recently started having problems starting. When I turn it on regularly, Windows Vista Home Premium starts with black bands on each side of the screen and your desktop extended / enlarged which does not display the start menu or the taskbar. I can navigate in the Panel, but when I click on the resolution of the screen, nothing happens and I'm unable to change the screen resolution. When I use CTRL and the mouse scroll wheel, I can reduce the size of the desktop icon, but the taskbar, nor start menu appears on the screen. I noticed that I can't start programs when the computer is in this State as well.

    I think that this problem started after I downloaded a game from 3 updates of Windows, but I do not know what updates they were.

    I am able to start safe mode and the office fills the screen normally. I don't know what steps I can take mode without fail to solve the problem of normal startup, however.

    Please let me know I you a glimpse into this situation because it is extremely frustrating. Thank you very much for your help!

    Hello

    Microsoft gives sometimes you updates for the 3rd party hardware: graphics, network cards, etc.

    You should only get the latest drivers for them to real hardware manufacturer's website, as Microsoft normally does nor those have the most recent drivers available as Microsoft relies of the 3rd party hardware Manufactuer to provide.

    But unfortunately, the only way to know which is the update of the problem is to install them one by one, until you find the 'wrong' for your installation.

    You can do a system restore to get back until it has been installed (which is NOT the best way to remove an update) or follow this method:

    'Remove an update'

    http://Windows.Microsoft.com/en-us/Windows-Vista/remove-an-update

You can then choose to download and install the updates that you want.
