Meet with RDP High DPI issue

I am connected to server 2006 from a Win10 notebook with a High-DPI Screen (FHD) and 125% of normal size. Text is too small and blurry when I use Full Screen. If I use other remote desktop sizes, like 800x600 or other, I get a smaller window and can’t zoom it up. What can I do to make it full screen and clearer?

It’s not hard to find that the screen is fuzzy and small when we RDP with high DPI to a server with lower DPI. The icons, text, dialog boxes and so on are blurry, and the process of RDP is not full screen, making it impossible to read and operate effectively.
