When I try to connect my pc to my Panasonic Viera TH-L32A2OM with a vga cable; the screen is kinda tinted purple in a way. It doesn't do this when i'm watching regular tv... how do I make my tv show my pc's screen as it is? Also; can I get the best picture settings for my TV?
Purple Panasonic PC>TV Problem:
The VGA cable uses three primary color RGB channels.
Red, Green, and Blue.
The picture is made up of pixels or dots arranged in a grid along the "X" horizontal axis and "Y" vertical axis.
The computer mixes the intensity of each color channel to create a unique color per pixel.
All RGB at 100% creates white.
R+G creates yellow.
R+B creates magenta, ie purplish.
G+B creates cyan.
So a purplish tint sounds as if your Green wire has no signal, which may indicate a faulty VGA cable or VGA socket.
Put another way, (R+G+B)-G=R+B=magenta.
So try another VGA cable, spray all socket pins with "Servisol " or similar contact cleaner.
0%<--------->100%
Cyan<------->Red
Magenta<--->Green
Yellow<------>Blue
All 0%=Black; All 50%=Grey; All 100%=White.

Your right. I just had the same "Invalid Input" issue as well and it completely relates to the resolution compatability with any VGA or HDMI connection. Check the LG website for the online manual if you don't have it and see the section on RGB-PC cable. There is a table that incdicates the Resolutions the LG product is capable of displaying.
Thanks for the help.

Most tvs can only handle a couple resolutions (ie 640x480) through the pc input. Even some HD tvs can only do 480. Check that your video is turned on and setup to the acceptable resolutions.

In the user manual it says what resolutions are supported. I think you have to adjust your resolution on your PC to match one of those listed.
