    Hello all,

    I bought a samsung 37" LCD TV. I want to connect my desktop CPU to it with a VGA cable. I have 1.5meter VGA male - male cable..... i used that and the picture quality is very good.

    I dont want to be my CPU placed near to the TV. I want to connect it from my bed room....it requires a 15mtr VGA cable..... I used a normal two wire cable (no shielding) to make a 15 pin VGA male - male cable of length 15mtrs.

    you can see the attachment.

    This time iam got so much disturbance in the video....how can i rectify the problem....
    if there is no solution....then i'll buy a new cable..

    thanQ

    Hello,

    For that distance you should use 5 X 75 Ohms coax cable.
    From the picture I see you have used unshielded wires.

    You will need a coax for each color and 2 for the 2 sync signals.
