Mega pixels to you a picture tells how big it is. digital photos of small points in the name of pixels and each of these pixels can immediately different color and Light.
The amount of pixels is defined by your monitor, not Excel or whatever application you use. So in landscape mode on different monitors, you would have different amounts of pixels.
However, pixels are different sizes on different displays, so the answer is 58.74 pixels per inch on a 75-inch 4K television, for example, but 440.58 pixels per inch on a 5"-inch full HD smartphone screen.
Pixels make up images. A bunch of different colored pixels are put together to make a digital photograph, or video where the pixels move around.

The number of horizontal and vertical pixels in a display box is determined by its resolution. For example, a common resolution for HD displays is 1920x1080, which means there are 1920 horizontal pixels and 1080 vertical pixels. The total pixel count can be calculated by multiplying these two values, resulting in 2,073,600 pixels for that resolution. Different displays may have varying resolutions, affecting the number of pixels accordingly.
The first CCD's were produced using the technology available at the time. This limited the amount of pixels a CCD could hold. Subsequent advances in technology reduced the size of the pixels, thus increasing the resolution.
Every screen will be different. You can approximate for your particular computer by dividing the height of the screen in pixels (the second number in your display resolution) by the height of the screen in centimeters. The number you get will be "pixels per cm" for your screen.
If you want to know how many pixels are in palm tree art is going to be determined by a few different factors. One of the most important is the size. The pixels can range from a few dozen to thousands.
