Hello,
I just bought a Panasonic TH-37PX80E television and we purchased a VGA cable to display the computer screen on the TV.
The image is very sharp, the colors are good, but the picture jumps every 50 milliseconds!
The signal frequency was the same as the computer, but it keeps jumping!
If anyone has a solution, please write it down!!!

re
the frame frequency is the scanning of a complete image in the vertical direction. In television, it is 20 images per second, which is half of the period of our alternating current power supply at 50Hz. This is an easy and universal reference in a continent (as far as TV is concerned). In computers, scanning can be much faster, and in the case of a TV, one must adjust a setting (back in the "heroic" days, there was a button labeled "vertical stability"). Now, it is managed by the graphics/video card of the computer. However, I suppose that Panasonic in PC mode with a VGA connection must have a frame frequency detector that stabilizes the image automatically. That's why I was telling you that it would be better to contact Panasonic; the hotline works well, and there is a real technician on the other end of the line.

Hello
the answer may be at Panasonic (it's quite nice by phone) indeed the frame frequency of the TV is different from that of the computer so the real question is where the adjustment is located, the setting of the graphics/video card or the impossible adjustment of the TV?
Good luck (it only takes a little)

Hello,
What is "frame frequency"?
On the television, there is
Clock [In the middle]
Position H [In the middle]
Position V [In the middle]
Phase adjustment [In the middle]
Synchronization [On green / H & V]
Reset [Confirm]
When "Synchronization" is set to "H & V" the image flickers
When "Synchronization" is set to "On green" the colors of the image are not right
What to do?

PS: This time, I am on a different PC with Windows 7 Starter and I do not want to call.

I just found my Panasonic manual for my TH 42 PV 500E, which proudly displays its five years without any issues. I read, without having tried it, the configuration to perform for a PC connection on two pages of the manual.
Finally, in the specifications of my television, there are the accepted frequencies for the vertical scan ranging from 49 to 86 Hz (the television is at 50Hz)
I hope that in order to address your incompatibility, you accept the principle of taking advice from the Panasonic hotline
Good luck
Otherwise, I will check the PDF manual that is on the Panasonic CD...
