Hello,

I have an old CRT monitor which has a bad VGA cable. The picture will display with a tint to it (due to one of the wires for a color being intermittent), and if I bend the VGA cable a certain way the picture will display normally again. The issue is towards the end of the cable at the connector, so I was wondering if I could take another VGA cable and splice it onto the monitor's cable? Also, would this cause interference to show up on the picture?

Thanks,
John

Impedance control is pretty important for analog video transmission lines. I would not recommend splicing the existing cable. Take the monitor apart and replace it entirely. Use a quality mini-coax based cable

I wholeheartedly second that . Impedance issues will generate signal reflections which will generating "ringing"/"ghosting" (not to be confusing with LCD ghosting which is totally different phenomenon) .

Here is an example of what "ringing"/"ghosting" can look like .

EDIT: "ringing"/"ghosting" is the faded doubling on the right side of graphic elements . The softness is a likely a bandwidth issue .
EDIT2 : Here is an example of "ringing"/"ghosting" without the softness . Re: VGA Capture Thread
