Both involve opening the Rendering Options windows. X-Plane just doesn’t have a “full screen” button. “Why can’t I make the X-Plane window fill the screen?” For example, to change the resolution from 1024 x 768 in the image above to, say, 1280 x 768, one would click twice on the arrow above the zero in 1024, six times on the arrow above the two in 1024, and four times on the arrow below the four in 1024. To change it, click the up or down arrow next to each digit of the setting. The screen resolution setting is found in the upper left of the Rendering Options window (highlighted in the following image). Click Settings (as in the image below), then click Rendering Options. In X-Plane, move the mouse to the top of the screen. Found in the section below is a discussion of changing the resolution in order to make the X-Plane window full screen.

Here we will walk through only the steps necessary to change the monitor resolution.
