Is there any way to turn off the screen of a Nikon D3300 whet is conected to the pc by USB?
The screen stays on so that you can monitor the activity taking place.
BTW, it is not advisable to use battery power when transferring images to the computer, since if the camera runs out of power partway through, all images on the card may be corrupted. Use the mains lead - it is what it is for. Alternatively, transfer the images by using a USB card reader, and placing the memory card in that.
