Can't change my screen resolution - Windows 8 PRO

I have computer LAPTOP Compaq Presario A900 in which I installed Windows 8 Pro. After the installation, I'm not able to change my screen resolution. When I right click on the desktop, and then select the screen resolution, it is written in the resolution 1024 x 768 (recommended)box. I can't change the screen resolution. In Device Manager, I tried to update my Generic PnP Monitor driver, it says that your driver is up to date.

This Device Manager cannot find generic drivers.  I recommend go to the Compaq website and download all the drivers for your model laptop (same drivers you already have, bring here to ensure that you have the latest version of the non-generic), but above all, including the graphics driver.

  • Satellite A200 - 14 d: how many times can I change the screen resolution

    I would like to ask if often resolution change may damage the screen of my Satellite A200 - 14 d?

    Because now I'm programming in Assembly in resolution 640 x 480, and whenever I run a program, the screen should change its 1280 x 800 to 640 x 480 resolution, and it takes 1-2 seconds: it is empty, the backlight turns off, then the new resolution appears. I would like to ask if it permanently (often) could damage my LCD?

    Thank you.

    Don't worry man, it will not damage the screen ;)

    I can't drag the arrow to change the resolution on my new laptop. He moves only from the highest to lowest - nothing in between.

    Hi Eileen,.

    Thanks for posting the question in the Microsoft Community!

    You can use only the highest and most low screen resolutions available and nothing in between.

    What is brand and model monitor?

    The resolution, you can use is based on the resolution that your monitor supports. CRT monitors generally display a resolution of 800 × 600 or 1024 × 768 pixels and can work well with different resolutions. LCD monitors, also called flat screens and screens of portable computers often support higher resolutions and better suited to a specific resolution.

    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.

  • Recent update has changed my screen resolution?

    Recent update of windows changed my screen resolution. Blow up all my icons, wallpaper and extends the size of windows. Pages do not correspond to windows, the computer and on the web. It is the second time that this happens, and I don't know how I straightened the last time. I know this isn't a major problem, it's just frustrating, as it has a mind of its own.
    Any ideas would be greatly appreciated.

    Change your update settings and do not install the the hardware driver updates left 3rd of Microsoft Updates. Find them in the constructor.

  • HOW can I CHANGE MY SCREEN RESOULTION SUPERIOR WHEN HE SAID that HE has REACHED HIS LEVEL of RECCMENDED?

    HOW CAN I CHANGE MY SCREEN RESOULTION SUPERIOR WHEN HE SAID THAT HE HAS REACHED HIS RECOMMENDED LEVEL? HIS NOTEBOOK from FUJITSU, upgraded to windows 7 AND I NEED of THE RESOLUTION to BE in 1024 X 768 TO RUN a PROGRAM, BUT I can NOT GET IT HIGHER than 1024 X 600.

    Your model number of Fujitsu is probably under the laptop, without it, you will need to get the driver from Intel. The mobile intel (R) 945 express chipset has been around since 2005, so you may well be stuck with what you have. You can try looking at the advanced settings for the graphics card in the Control Panel, or via the office, sometimes, you can increase the allocation of memory with integrated graphics card, have a look at performance video on this page, when you get to the tab of the map which is where changes can sometimes be made: -.

    http://www.Dummies.com/how-to/content/understand-PC-graphics-display-adapters.html

    the example shown is for the dedicated graphics card, yours is integrated, but you should be able to cope if a choice is available.
