Can connected equipment, such as hdmi, scart, vga cables damage LCD screens? My thoughts are this, we have a GeForce 7910 GTO GPU card in our pc, it is power hungry, it has 2 outputs on the back, one connected to our LCD tv, the other to the PC monitor, can this ever damage the LCD tv as there is a lot of power going through the card and down the DVI-HDMI cable??? I'm probably being a little thick here, but any chance of electromagnetic radiation on a huge scale? Like when you put a magnet near a CRT tv???
