The situation is as follows:
My ProgramWhen running in a notebook + XP, notebook + 2 K, desktop + 2 K + LCD, the display is normal,
When running on the desktop + CRT (17 flat screen) + XP, the image is not fully displayed, and the buttons on the image are misplaced and the resolution is set to 1024*768.
What is the problem? How can this problem be solved?

It should be your program problem, not the display reason

I made a small program and put an image and several buttons in it. The result is still misplaced.
Originally, the image is as big as the window, but it becomes smaller on the desktop + CRT.
You can give me a solution. Thank you!

It's not a program, but it must be a problem with your program.

The DPI of the CRT should be set to greater than 96, such as 120.

View DPI settings under "Display Properties"> "advanced"> "General.
