I use the following code to get my computer screen size

int chieurong = SystemInformation.VirtualScreen.Width;
int chieudai = SystemInformation.VirtualScreen.Height;

Sadly, the return result is: chieurong = 1536 chieudai = 864 While my laptop screen size is Full HD (1920 X 1080) Please tell me where did I go wrong?

Use `Screen.PrimaryScreen.Bounds` which represents the actual bounds of the display. – Trevor Jul 01 '21 at 13:49

I tried your way but the result is still (1536X864). – Hướng Phan Ngọc Jul 01 '21 at 13:52
`Screen.PrimaryScreen.Bounds` depends on actual resolution setted in OS display settings. – Auditive Jul 01 '21 at 13:58
It's confusing when the results I run out are completely wrong. https://drive.google.com/file/d/1cffRrD8PBdi1IBeJ24F-ZnxGsTHVkX6n/view?usp=sharing – Hướng Phan Ngọc Jul 01 '21 at 13:59
Scaling also does. Set it back to 100% and you'll get 1080p. – Auditive Jul 01 '21 at 14:01
I got it. Since my screen size has zoomed in more than 125%. – Hướng Phan Ngọc Jul 01 '21 at 14:02
