  • Firefox installed on Windows 7 but the menu bar and icons is filled with small horizontal lines on the icons and the menu bar...

    I installed Firefox 21 on a new Windows 7 operating system. The menu bar and the toolbar at the top of the windows is full small horizontal lines. Sometimes, there are more lines and sometimes less. It makes the icons and menu items almost impossible to see. So far, is that the Firefox screen that made it. Other programs I have installed so far doesn't do this.

    Any ideas?

  • Touch force constantly removes the gesture and replaces it with a straight line from the starting point to point stylus. Is this a bug? It made impossible delicate designs on iPhone 6 s more.

    More iPhone 6s and Adobe Illustrator drawing

    When establishing, too much pressure removes the gesture and replaces it by a straight line connecting the initial start of the drawing just under the pressure point. This makes delicate drawing impossible. This affects all types of brushes and occurs when you use your finger or the stylus. Deleting the app, reboot the iPhone and reinstalling does not remedy the problem.

    As long as we don't have contact with the screen and varies the pressure beyond a certain point, the gesture will be constantly removed and replaced by a straight line. This issue was present in the previous version, and in the course of December 3 update.

    > Satellite Pro L40 - how to make a dual boot with two recovery disks?
    Short answer: you can't do that. Maybe if you have two hard disks (I tried didn't) but as much as I know your SP L40 has only one.
    Ask this smart guy, how to do this. Maybe it's a useful tip.

    Hello

    I fear that the problem is related to a hardware problem m.
    The internal display is affected or the graphics chip on the motherboard is faulty.
    In both cases the hardware must be replaced
    Therefore, you should get in touch with a partner service is available in your country for this problem

  • HDMI output on Qosmio G40 - horizontal line on the screen

    I connect my Qosmio G40 to an 46F86BDX of Samsung LCD via HDMI. On all my films, when there is a shift, I see a horizontal line on the screen. Sometimes is in the middle of the screen, sometimes lower.

    I tried my pc with another TV and a different cable, but the same problem. Someone knows the same thing?

    Thanx

    Hello

    > On all my films, when there is a shift, I see a horizontal line on the screen.

    If I understand issue you this horizontal line appears ONLY on and external TV and ONLY if there is some faster movements of the pic.

    If so, then I think it has nothing to do with G40 Notepad.
    I have read that those issues could be related to the new TVs LCD then to watch movies in high definition.

    I think you should read a few tests and reports on similar issues on LCD TVs

    See you soon

  • HP EliteBook 8440p: white horizontal lines on the screen who retreat down in the minute

    Hi again. I've already posted about this so there are pictures and a full description of my post a few days ago. In short, when the laptop was arrested or sleep for more than a few hours, it is white horizontal lines on the lower part of the screen that slowly fade completely down. The lines do not appear on an external monitor in dual mode.

    I removed the screen twice now and checked / reinstall connections to the screen and under the keyboard. The problem persists.  I flashed the BIOS a few days ago and the problem persists. The webcam, microphone and WWAN/WLAN are all in perfect condition and the computer works fine apart from this problem of screen work.

    Until I drop the most money on this used laptop that is my only question at this point sounds as strictly a matter of cable/display on the screen? If it's a motherboard problem I would see other problems? If it is the graphics card goes wrong I would see other problems? As I said, the computer works perfectly once it is running.

    Anyone has any useful ideas?

    Hello

    You can try to connect this unit to an external monitor to check if there is a problem with the motherboard or display

    If the external monitor works fine, then there is no problem with the motherboard, only the display panel needs replacement.

    If the problem persists in the external monitor, suggest you to update the graphics drivers and see if the problem resolves

    I hope this helps

    Hi all

    I have a DESIRE DV6-7246us, just updated to upgrade to 8.1 WIndows, yesterday, display fell asleep and trampled, I now have a flickering horizontal line at the top of page 1/3 of the screen. It is a single horizontal line that appears to wrap the text what ever he is going through, around the other side of the screen.  windows 8.1 upgrade was completed Monday, and the line began yesterday.  The computer is stock, with a genuine copy of Windows.  Please help I have runa small business, and this computer is invoked daily.

    Thank you

    Hello again,

    I could solve the problem with an updated graphics AMD HD SP60282 driver.  The only horizontal line has disappeared since I updated the driver.  Previously, it did not matter if I rebooted or the monitor kept awake, it never disappeared.  Now everything works as it should.  The driver can be found by searching SP60282 on the HP site.

    Thank you!

  • The horizontal lines of the screen problems

    Hello

    Since I use Windows 7 X 64 on my T500 2241, I have problems with many small horizontal lines on the screen. The same one I have on an external monitor. With Win XP 32 bit, I never had such problems on this computer.

    May that this problem is related to the video driver. I use: Intel Mobile 4 Series express chipset driver version 8.15.10.2302. I had the latest bios update for my computer.

    Nothing helps. Y at - there a better idea?

    Thank you very much

    My computer with two hard drives and 2 starting systems has the car crash in the solid state. When I got the new drive and tried to restore from time capsule, I lost some data. How can I see what backups are on the time capsule? My laptop is also saved to the time capsule. Everything is in 'Data' when I look through the Airport utility. I think that the information that I've lost are still there since I was a Capsule 3 to.

    Time Machine backup to a sparsebundle.

    The sparsebundle will use the share name of computer. So, it should be obvious who is your Macbook and that is your Macpro.

    Open the sparsebundle in Finder and keep open the subfolders until you get to the backup of each separate hard drive...

    You has of course set the exclusion in Time Machine?

    By default, Time Machine will exclude your second drive unless you have included it. Did you?

    Once you get to this level during the backup, you can do a full restore manually whenever you want.

  • Satellite L830 - horizontal line across the screen

    All new Satellite L830 has a horizontal line across the screen.

    What can be the cause and how can be fixed?

    If the laptop is brand new it back as soon as possible and ask for replacement.
    On this virtual path, it is not easy to say what the problem is here, but it may be related to faulty display, especially if you can see from the first moments when the laptop is turned on.

    Don't try anything. Request a new one. If you can not new, contact the nearest Toshiba service provider and ask for help. They need to exchange the defective part.
