I'm a preschool teacher. I want to use my cellphone as a microscope while hooked up to my laptop so that what is seen by the phone can be seen instantly, in real time, by a classroom of students on the bigger computer screen. I have a Samsung Galaxy 3 cellphone, and a Dell laptop. I have tried using both a USB cable and an HDMI cable with no luck. I've tried the mirroring option on the phone also with no luck. And I've even tried using my Dell TV screen with no luck. I can take great microscope-type pictures with the phone, and I can download photos from my phone to my computer, but that's not what I want to do in this case. I want the computer screen to see what my phone sees in real time. Any suggestions? Thanks! ~shannon
