Windows shows wrong resolution compared to display

Solution 1:

I believe that there is no problem.

The correct total screen resolution is shown by the Control Panel Display applet and by the graphics control panel and by the dxdiag utility.

However, websites report the resolution as given by the browser's JavaScript window.screen object (see reference), which is the adjusted size that is usable in the browser for displays in full-screen mode.

This size is lower than the values reported by the computer, since the browser uses up a part of the screen for its own adornments, such as borders and toolbars and sidebars etc. , and Windows itself is also taking up a part of the screen with its taskbar etc.

In short : Windows shows the correct values and you have no problem. Do not replace your Windows display drivers, or you will create real problems.
