4000 series LED-LCD TV

Where can I buy parts and accessories such as remotes, TV stands, etc. for my Philips product?

What size bolts do I need to mount my PhilipsTV? What is the VESA pattern?

Can I use a VGA-HDMI cable to connect my PC (VGA OUT) to my Philips TV (HDMI IN)? How do I connect my PC to my Philips TV?

When should I run the auto program feature on my Philips TV?

Why is the picture on my Philips TV distorted (stretched out, short and fat, black bars on side or top, etc.)? Is there something I can do to make it better?
