Apparently noone ever needed anything like this on the internet because I was not able to find any example, so I hope this will become the reference question.
I need to repeat a vga 800x600 signal up to 15 meters away but can't find any decent reference for this. The signal is a CCTV dvr output signal. Commercial VGA repeaters are quite expensive ($160 each) and I'd like to be able to make one on my own.
It seems as if it is not that easy but after all it's an analogue signal, is there not any atmegaXXX chip which can repeat an analog signal on its outer pins?
All I found was examples of very poor graphic quality like below, very far from being a 800x600 color video!
