cables with thick cylinders on either end usually have ferrite cores which reduce interference. here's an example:
First off I would like to say thank you to anyone who has taken the time to read this. This is my first post, and I am hoping someone here can help me out with this problem.
I recently purchased an ACER X213w LCD monitor to hook up to my laptop, an ACER Extensa 4420. I am having problems with horizontal lines running across my screen and I have figured out that it is an issue with my laptops power cable being too close to the VGA out port. The lines go away when I unplug the power cable, so this is how I came to that conclusion, and with a little reading on the internet. I have another external monitor that I hooked up just to see if it would do the same thing, but it didn't have the lines. This monitor though has the VGA cable coming right out of the monitor, as opposed to my ACER monitor that just has a VGA cable with two male ends that you can remove.
I am thinking it has to do with the cable. I have tried two different VGA cables, and neither of them have worked so far. I was wondering if someone could suggest a good quality cable that you know will block this interference. Or could the reason it isn't happening on my other monitor be the fact that the VGA cable comes straight out of the monitor?
I am stumped on how to fix this if it's not the cable, so any suggestions would help. Please let me know if I haven't described this well enough.
