The resolution of the Windiows 11 display is to low for the user to recognize the text on the screen

The interface have been changed on Parallel Desktop: the mouse will be captured by Parallel Desktop and if the user need to use mouse in MacOS, he can press Ctrl+Opt to release the mouse from Windows. This didn't use to occur before, but what I can't accept is that meanwhile, the resolution of the Window became very poor, as shown in the picture (https://cloud.189.cn/t/3Ubame6VjMzq, password: kj5f).
Since the text in Windows is difficult to be recognized, it's hard to set the display resolution in Windows. One attempt was made to set theResize by Windows Manager, but it doesn't change the resolution, but the windows size. Setting the resolution in Graphics from the Config menu also doesn't work, whatever the "Best for Retina", "Scaled", or Best for external displays" was selected.

So, my request here is if there is a way to reset or optimize the resolution so that at least the text on the screen can be recognized. Look forward for the reply and many thanks!
