How to fix bad sound quality with my Philips Projector when using a computer connection?
If you experience poor sound quality on your Philips Projector when connected to a computer, verify that the audio cable is connected to the computer's headphone or line-out socket. Also, ensure that the computer's volume isn't set too high.
What to do if only the initial screen appears and not the image from the connected computer on my Philips PicoPix PPX3407?
If your Philips Projector only displays the initial screen when connected to a computer, ensure that the computer's VGA output is enabled and that the computer's resolution is set to 800x600.
Why does my Philips PicoPix PPX3407 change brightness when playing videos over USB?
If your Philips Projector automatically dims when playing videos via USB, it might be due to high ambient temperatures. The device reduces brightness to protect the LED. Try using the projector in a cooler environment.
