Informative text on Display Properties dialog box

In the "Display Properties" dialog box "General" tab, where we can adjust the "DPI" value, I think it would make a lot of sense for an informative text to explain to the user what the "DPI" value means, in order to assist him in his decision. , modify or not this value.
In addition, the titles of the checkboxes are not related to color but to the definition of "DPI".
Check out the snapshots I added, the window arrangement is much more visually adjusted, filling and dividing the free spaces better.
Additionally, the text displayed in the "Display Properties" dialog box on the "Settings" tab only makes sense on a multi-monitor system.
For these reasons I propose to display the info text on the "Settings" tab only on a multiple monitor system, and other info text on the "General" tab.

Implementation of the "Custom Setting dpi value" Dialog Box.
