To enable/disable HD Mode:
Use “My Computer” and find the DroidCam installation folder. By default this is “C -> Program Files or Program Files (x86) -> DroidCam“. You’ll find a “Toggle HD Mode” shortcut: right click and pick ‘Run as Administrator’. You will be presented with a picker dialog. Clicking OK will trigger a computer restart.
*The app and client will use more CPU/memory/power in HD Mode.
*Note that if you are using the free version of DroidCam, or if your device doesn’t support HD video capture, video frames will be upscaled and look low quality.
