Hi,
Your Panasonic TC-26LX20 26 will only allow video inputs through the:
1. composite video/audio input ( RCA phono x 3 ) - front or rear
2. S-Video input ( 4 pin mini-DIN ) - front or rear
3. component video input ( RCA phono x 3 ) - rear
4. HDMI ( 19 pin HDMI Type A ) - rear
Depending on the output(s) available from your PC, you can use any of the following:
a. the yellow RCA female
b. S-Video output ( 4 pin mini-DIN )
c. VGA (which normally goes to the monitor) but would require a VGA/HD to HDMI Format Converter such as the one
hereShould this be not enough information, please post back with what PC brand/model that you have. Additionally please specify what Video Card are you using if your PC is a desktop.
Good luck and kind regards.
