How to display a higher screen resolution than what is supported by the monitor?

Question

Screen resolution

Let's say we have a monitor with a resolution of 800x600. You need to force Windows to generate an image in a format, say, 1600x1200, and then compress it to 800x600 (replace 4 pixels with one) for further display on the monitor.
Is there software for this purpose?

Answer 1

An image can be generated in any resolution, as long as there is enough memory and disk space.
On any monitor, you can always display an image of a higher resolution than the monitor. To do this, web browsers, let's say, on the fly (without saving the result to disk) perform an image resampling operation: Algorithms for scaling pixel graphics
