How do I get my eMachine PC to work on my Philips LCD TV?

VGA is an analog signal. HDMI is digital. You’ll need to either:

1. Replace your video card with one that has an HDMI or DVI plug on it
2. Purchase a VGA to HDMI converter box: http://bit.ly/p6ydrO

I’d suggest going with the video card replacement if you’re using a desktop PC since the cost will be about the same. If you have a laptop, you’ll need the converter unless your computer has a DVI connection, if so you can just use a cheap DVI to HDMI adapter plug.
