• 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

• Solid black line on the screen of the HP Tablet

  I just got this HP 7 5709 flow. So far so good except there is a horizontal black line across the screen. I first thought, this is the screen protector, but now I'm starting to think that it is in the screen itself. Is - is this known? Attached to the image here. Thank you

  all kinds of lines on the screen that persist all the time are defective LCD screens and will need a replacement.

• Finally two updates slightly incompatible with Windows 8.1, appearance of flicker black dots on the screen?

  I would say that this last two updates. latest Firefox version 32.0 have a compatibility issue with Windows 8.1.
  My laptop newly bought worked fine with Firefox until recently. About two to three days before, during the navigation. blackheads should blink on the screen. At first, I figured well problem of pixel, but after testing the same sites with IE 11, these black glitter points seemed not at all. I tested it with chrome and no points.
  These black spots have not appeared before on Firefox, only recently. Unfortunately, I'm very uncomfortable with the use of Firefox that I had been using this browser since 2005, but this compatibility issue makes it difficult, cause flickering points can be annoying.

  What you describe was reported before and it is almost always bound by graphics drivers. Firefox will (by default) use hardware acceleration to help speed up the rendering etc. On some graphics cards/driver combinations (most with Intel video) people reported black dots. Disabling the hardware acceleration option usually clears this up.

  Does look like this: https://bug913419.bugzilla.mozilla.org/attachment.cgi?id=831738

  Some other threads for reference:
  https://support.Mozilla.org/en-us/questions/974717
  https://support.Mozilla.org/en-us/questions/856277

  It is not limited to Win8.1 - were reported on both Linux and workaround there is to change the method of hardware acceleration... until the Intel video driver has been updated.

• Why is my screen turning black temporarily, then the screen saver turning blue, when using hotmail?

  Sometimes when you use Hotmail - specifically, put the cursor in the e-mail box - Mac color wheel starts to turn. It is quickly followed by the entire screen goes black for a few moments. This is followed by the screen back, but the background changing default screen saver is blue that usually appears temporarily when I boot. This happens not all the time, but it happens. I visited the 'genius bar' Apple Store and they checked on my machine. They cleaned up some disk problems, and it is always the case. Their thought is that it is a Firefox problem, because they did not experience to date, and it didn't happen when I use hotmail with Google Chrome.

• Tecra M4 - lines of vertical black pixel on the screen

  Hello

  This morning I turned on my laptop and suddenly I have vertical black pixellines more my whole screen.
  There's a line that works normally, who is black, a job, a black man,... and this all over the screen.
  In this same way read something is very difficult.

  I have no idea what can be wrong, I did not install something recently or anything like that. I tried the system recovery, but the problem will not be solved.

  No idea what this can be?
  I appreciate your help!

  Sincerely,
  Seppe

  > I tried system recovery, but the problem will not be solved.
  It looks like a hardware problem, but try the BIOS default. In order to access the BIOS press ESC and F1 at the beginning.

  On the other hand I recommend you connect the external monitor to the laptop to determine what might be wrong.
  If the same lines would appear on external monitor, then a graphics card failure can cause this problem ;(

• Satellite P750 - grey and black stripes on the screen

  Hello

  I BOUGHT MY NEW TOSHIBA (3D) AROUND A MONTH AGO P750
  AT TIMES RANDOM SCREEN WILL BE BANDS GREY AND BLACK HORIZONTAL AND VERTICAL
  IT IS GETTING WORSE FROM WHEN HE STARTED
  ALSO WHEN PUT ON THE TOSHIBA START LOGO ON SCREEN BEGINS TO BLINK
  SOMETIMES PASS THE SCREEN WIL HELP.
  NOT VERY HAPPY AS ITS NEW BRAND.
  COMPUTER LAPTOP MOVES FOR EXAMPLE HIS USE NORMAL OF A HOME WORK.

  ANY IDEA WAT I HAVE TO DO?

  In my opinion not only make sense for you is to contact your local dealer where you bought your laptop or a provider of services of Toshiba directly.

  You have for laptop with a valid warranty and if something like this happens, it must be fixed, or you should get the new laptop.
  Call the service, ask for help and I'm pretty sure that they will help you with that.
  Do you know how to find Toshiba service in your country?

• Black finger across the screen to the bottom only in locked mode - retina 2014

  Mine is a MacBook Pro (retina, 15 inches, mi 2014) 2.2 GHz with integrated display. When I opened the laptop this morning, I was welcomed by a screen locked and noticed a black spot on the lower part of the screen. My heart sank for a moment, but when I logged in, I did not notice the finger any longer.

  I see the black spot that looks like an ink spot (see photo) when I get back to screen locked again. What is an LCD failure or is there something else going on? If it's an LCD has failed, why not see the problem when it is unlocked? How to fix? Thanks for any help.

  

  Notice the black spot. The white point at the bottom left of the screen above is just the cursor hidden.

  

  No stain when unlocked can be exceeded.

  Could be a hardware failure.  If you bought AppleCare, you have 3 years warranty on the material and can diagnose the Genius Bar it repair free of charge - it is reproducible, so you can show them.

• An area or a window, black, flashing around the screen, preventing the normal operation of the computer.

  I have a flashing and move the black box. In addition, a little black "bug" moving on the blue bar at the bottom of the screen. I stopped him temporarily. It says "the application could not initialize properly (0xc0000142). Click OK to close the application. "When I do the flashing box back and kind of takes the P.C., preventing a 'normal' operation of the computer. Any thoughts, please? As you can tell I am ignorant with respect of the computers please dumb it down for me? Thank you.

  At the moment, it seems to be contained in a box titled "cmd.exe - Application error.

  Can I get rid of this or should I consider for repairs, once again?

  Thank you, Alan

  I turned on the computer this morning and "PRESTO!" It has been fixed! I just figured (assumed) the fairy Magic computer was coming over the magic fairy dust at night and sprinkled on the keyboard and instantly, better everything! Ridicule me.

  Joking aside, this means - it has declined and is still in my system, lie dormant, so to speak? He wasn't there this morning. I honestly thought that Microsoft Security had just sent an update and just sort of 'fixed' it. I am both ignorant and naïve.

  Don't tell the bad guys, or I'll be marked, "EASY!" as a target.

  Should I just leave well enough, only? As in, if it's not broken, don't fix it.

  Or I followed the procedures laid out for me in the above section?

  I know I'm not very clear. I'm sorry.

• Windows 7: Black flash of the screen and no user at startup

  Whenever I boot Windows 7 Home Premium on my wife s Dell, no presentation of users after the Welcome screen. Diagnoses are thin back and there is no change in safe mode. It shows just the white background of Windows 7 and periodically flashes black. This is my wife's computer, and I can't do anything for risk data. Thanks for any help.

  Hi Spencer,.

  Thanks for posting your query in Microsoft Community.

  Sorry for the inconvenience caused with Windows 7.

  More details would help us to best help you.

  1. "diagnoses come back fine and there is no change in safe mode", you are faced with this problem to the in/login-login screen? don't you realize that the user accounts to the login screen?

  2. "periodically flashes black", are you able to get to the login screen or this problem occurs before the login screen?

  4. What is the brand and model of your computer?

  Unplug all external such as USB key, printer, and scanner etc., devices (except keyboard and mouse) connected to the computer and check if the computer boots to the screen.

  If this problem (white screen) occurs before the login screen, you can do the Startup Repair by referring to article.

• How can I remove large black border on the screen

  I have an Alienware OptX AW2210 21.5 "Widescreen Monitor at resolution 1920 x 1080 (recommended settings) running on Windows 7.  No problem initially, but after an update there are now a wide black border around the outside of my screen and I can't get rid of it and make the display extend to cover the entire screen area.

  Thanks for the tips.

  It was a problem of scale.  I had to access the HDMI from the Catalyst Control Center nozzle and change the scale to 0% - did the job.

  This looks like a probable hardware problem.   Check your RAM and temperatures although it may turn out to be the video hardware itself.

• Dell Inspiron 15: Vertical black line on the screen.

  Dell Inspiron 15 , I bought about 8 months ago. The specs are as under: -.
  Intel Core i3 3217U clocked at 1.8 Ghz
  4 GB RAM DDR3
  1 GB Intel HD 4000
  1 GB AMD 7670 M (switchable)
  500 GB HARD DRIVE AT 5400 RPM
  Windows 8 Core 64-bit Edition

  The laptop was working absolutely fine with no problems until yesterday. Today morning when I turned on the laptop, I noticed a vertical black line on the desktop with an endpoint at the end of the line on my screen. At first I thought it would be a graphic bug which would disappear on reboot, done repeatedly, but no avail. The black line is more noticeable on a light background.

  Laptop has not been submitted to harsh handling or stress. What could be the cause of it? Is it a manufacturing fault or something else?

  I am attaching 2 photos of the screen from different angles to obtain a correct and complete line. Please tell me how should I proceed from here.

  

  

  Contact Dell for a replacement of the LCD warranty.

• Black square on the screen when the GPU is used?

  Hey everybody.

  Since I got my new computer, when I turn on the graphics processor, a black square appear and seem to block some of my screen. The problem may be solved by disabling the graphics processor, but it will limit what I do. IM using windows 10 64-bit and my graphics card is an asus 1080GTX.
  the black square on the side.

  Not yet done.   Disable the GPU on Adobe Camera Raw feature.
