Satellite A500: Can not change screen resolution

I have an A500 - 15 M with a 16 "display, which is more than a year.
He worked always very happy with a resolution of 1366 * 768, which is the size of the screen (a little unusual).

No reason apparent, this morning, it starts with a screen resolution of 1280 * 800 and does not anyway to get back to its normal resolution.
The result is a screen that is not full width of the screen, but which covers the bottom.

Vista option display settings will not allow anything beyond the amount of 1280 * 800 and no fiddling with the graphics settings (Intel) will fix the problem.
OS is Vista32 but the problem is still there after a relocation in 64-bit mode.

I have this terrible feeling that I did something really stupid, but I am at a loss now - any suggestions or help would be very appreciated

Hello

You have an Intel graphics card?
I think that first you need to update the graphics driver.
To be honest, I never had no problem changing the screen resolution, but I would like to reinstall the driver first.

I think you could try the latest driver for graphics card in the Intel page.
These drivers should be up to date so try it out and then try to change the resolution again.

    Change the screen resolution

    Screen resolution refers to the clarity of the text and images on your screen. At higher resolutions, items appear sharper. They appear also smaller, so more items adapted to the screen. At lower resolutions, fewer items adapted to the screen, but they are larger and easier to see. At very low resolutions, however, images may have serrated edges.

  • Why I can not change the resolution of the screen on the comments?

    Greetings,

    I used VMware Player to create a RHEL 5.5 on Windows 7 host. The resulting virtual machine has a screen 1440 x 900, but when I run the screen is 800 x 600. With the help of the utility comments to change the resolution of the screen only gives the choice of 800 x 600 and 640 x 400. Note that the installation of comments has been made using 'I'll install the operating system later'. If this option is not used and that the guest is installed either using the 'easy' option or the 'Advanced', this problem does not exist. Anyway, there is a big difference between a genberated of comments using the 'easy' or 'Advanced' option and the generated with the option "I will install later. Any suggestions would be much appreciated.

    Many thanks in advance,

    Nicolas

    VMware tools are installed in the comments? Next to important things, they contain the video driver that allows to change the resolution.

  • 4 K TV can not change the resolution or refresh rate

    When I connect my end of 2013 retina MacBook Pro to a TV 1080 p via HDMI, system preferences port gives me a list of supported resolutions and refresh rate to choose. But when I connect to the laptop even to my new Vizio M43 - C1, it generates a fixed 3840x2160@30Hz and gives me only a handful of options for scaling HiDPI. I want to change frequency to 24 Hz for movies, I do all the time with TVs 1080 p, but I can't find the option anywhere. SwitchResX works, but are there seriously no official way to change the resolution and refresh rate when a 4K TV is connected? Looks like a massive oversight.

    Hello NeilT6,

    These 4 k TVs sound incredible. If I had one I would like to than the best resolution, that I could not too.  Have you tried now hold Option key while selecting the display scaling settings?

    Use screens 4 K and Ultra HD TVs with your Mac - Apple Support

    Pointing your mouse on a resolution options will show more details about this option. To get a button detect displays appear, press the Option key. To see all available resolutions, press Option key while clicking on the button of the chipped.

    Take care.

  • NB200 - can't change screen resolution

    Hi, I have a strange problem with a netbook NB200.

    The screen resolution is set to 1024 x 768 with the lowest resolution to be together is 800 x 600 as a result no parameter displays correctly on the netbook screen and the Start button, taskbar, etc are missing.

    The native resolution for this machine must be 1024 x 600 - however, it is not available in the list of troubleshooting steps that can be chosen.

    Here are the steps that have been taken so far;

    (1) to restore the machine to resolution of parameters - the parameters of origin of wiping machine - factory defaults to 1024 x 768
    (2) load the latest version of the BIOS just to see if the BIOS had an impact - don't think it would, but I tried anyway.
    (3) the adapter graphic to uninstall and reinstall the Toshiba europe site (intel 945 mobile (r) express chipset)
    Graphic adapter installed okay more low resolution is 800 x 600 and 1024 x 600 option is not available.
    4) noted that the default monitor is still listed as "digital flat panel 1024 x 768".

    At present, the only way to use it is with an external monitor.

    For now it doesn't help as a netbook - someone has any ideas to try because I am running out of ideas with this one.

    Thanks for your help.

    Hi foxpc123,

    All that you have done is correct and you have tried everything, but if the factory settings doesn't help reset and screen resolution is automatically 1024 x 768, again, he must a serious malfunction of equipment. I can imagine something with the graphics card itself is not okay and so the monitor properties can t be detected correctly.

    You need to contact a service provider authorized in your country. Guys can check the equipment and replace it. I put t know how old is your notebook and if it s under warranty, but the warranty repair material is free. This means that technicians can fix that for free, but if not, you will have to pay for the repair.

    So the easiest way is you contact with the guys and talk to them. I m that you can clarify this with the technicians. ;)

  • How can I change screen resolution in firefox in 1280 x 720

    Recently, I switched to windows vista ultimate.
    I installed firefox 4.0.1.
    When I open firefox the screen resolution goes to 1280 x 720 to 800 x 600 (or 640 x?).
    How can I fix so I have 1280 x 720?

    If I have to can use Win Explorer how I transfer my firefox bookmarks to explore

    I think that this may be caused by a parameter in the shortcut that allows you to start Firefox. If you close Firefox and right click on the shortcut (for example, on the desktop or quick launch, is relevant), choose Properties, then the Compatibility tab, try to clear all settings. Then restart Firefox. Who help me?

  • How can I change the resolution of my pictures stored in Google Reader?

    How can I change the resolution of my pictures stored in Google Reader? I want to have received their approval, but they were taken with a phone and the resolution is not large enough to produce a clear image.

    Hello

    You cannot add true / resolution of the details of an image that is not captured when the photo was taken. Photo editing applications can adjust the sharpness, remove noise, etc., but they can't add true / resolution details and results may vary, massively, the photo and the filter/tool used (and configuration for tools).

    If you have reduced the resolution of the original image to store it on Google Drive, then I suggest that go back you to the use of the original image (if you still have a copy).

  • I can not change the type of standard user to the admin account.

    I had a very difficult time, adding new accounts to the system.  Now that I have, I can not change the type of standard user to the admin account.

    As you don't declare that you tried, I am unable to say where you went wrong. Here is a method to promote the accounts without going through the various GUI screens:
    1 restart in SafeMode with network.
    2. log on as an administrator.
    3. click on start.
    4. type the three letters cmd in the search box.
    5. press on Ctrl + Shift + Enter
    6. click on "run as Administrator".
    7. type the following commands and press ENTER after each:
    NET user
    (This will show you all existing accounts)
    net localgroup administrators 'xxxx '.
    (This will encourage user xxxx to Administrator status. Replace xxxx with the correct name account).
