Not able to use the Zoom or Focus settings in menu


I just purchased a USB 2.0 Microscope and the Zoom and focus adjustments in the menu do not work. It will not let me adjust any settings. Please, any suggestions?


Thanks for asking!

The menu you see when you click “More…” in Digital Viewer’s setting is generated by the DirectShow API in Windows. Options are greyed out because the chipset is not capable of those options. They are only presented because this is a generic menu generated for all devices using DirectShow.
