2 screens - different sizes of mouse pointer?

I have connected two identical monitors with the same resolution to my laptop. Since my PC only has an HDMI output, I connected the second screen via a USB-HDMI adapter.

So far everything works great, except that the mouse pointer is significantly larger on one screen.

I use the screens in advanced mode and when I move from one screen to another the mouse pointer just gets bigger. The rest are absolutely identical.

What can I do?

2 screens - different sizes of mouse pointer?

Are program windows on the other monitor bigger? If so, it is probably because the second monitor is physically larger. Then, with the same resolution, the content is logically larger.

No. As I said, they are identical monitors with the same resolution
