Trick To Increase The Screen Resolution From 1024x600 To 1024x768 Or Higher

Many netbooks come with a default 1024x600 pixels (or similar) small screen resolution, which can cause problems in some apps or a lot of awkward scrolling. If you want to increase the amount of screen real estate you have on your netbook or be able to use apps that require higher-resolution displays (such as the Metro-style apps in the Windows 8 Developer Preview), you might be able to change a registry setting called "Display1_DownScalingSupported" in Windows to get options for higher resolutions. Here's how to search for the setting and change it:

Netbooks generally use Intel’s integrated graphics. The Intel graphics driver contains a hidden setting to enable “downscaling.” Essentially, this will allow you to set a higher screen resolution in Windows. The graphics driver will then “downscale” the image to fit your screen. This will make content look blurrier, especially on the desktop – but if you want to watch videos and play games in the Modern environment, it may be a fair trade-off.

• Go to the Start menu and type in regedit in the search box, then hit Enter.

• Scroll up on the left pane to make sure you are at the very top of the tree.

• At the top menu, go to Edit then Find... and search for Display1_DownScalingSupported

• Change each instance you find (you'll likely find 2 results for this) from 0 to 1. Make sure you   change every found instance, because otherwise the hack won't work (in my experience).

• Once done, restart the system.

2nd Method

 There's a simpler way...

    1.  Go to the Desktop, right-click and select Screen resolution.
         A window opens named "screen resolution"
   

    2.  Select the option Advanced settings
         A window opens with 3 tabs (usually), select List All Modes under the Adapter tab.
    3.  Choose your desired resolution and click Apply, Apply, OK.

That's It Enjoy!!
