Logitech Webcam C920 HD720 autofocus at 10cm performance good

Now I am checking out how C920 autofocuses in HD720 at 10cm close up.  I found it good.  My 17" BenQ LCD mon has a native resolution of 1280 x 1024, so the HD720 of 1280 x 720 does no fill up full screen.

C920 can shoot at 1920 x 1280, but my 19" Philips 190B can display only 1280 x 1024.  So it is difficult for me to test HD1024.  I would stop at HD720, which is already good for me.
