Does the Microdisplay used with Eyepiece have a higher resolution, the better?
The answer is not necessarily.
It can be understood that the resolution of the human eye is limited, too high-resolution microdisplays such as UHD cannot improve the effect much, and the 4μm pixel almost matches the human eye.
Quanhom GE25 supports screen size of 0.61 inches and a pixel size of 4μm. In general, an SVGA resolution of 800x600 is sufficient.
