VGA cable not recognizing monitors

I have an ACER P193W, and its standard VGA cable that came with it is more or less, broken. The image is blue-ish, and if you apply a bit of force and stretch the cable the image comes back to normal. The thing is though, that at the smallest movement the image reverts back to blue, so I went to a local store and bought a standard VGA cable. 

Everything works fine, except that the PC no longer recognizes the monitor, and the fonts and icons are blured. Overall the image looks very nasty.

I have another monitor, a Samsung...943NW, and if I use its standard cable that came with it for my acer, the PC recognizes the monitor, and the image is good.

 

What cable should I look for, because I already bought two cables, with no success, both for the Samsung and the Acer...

What would happen when you use the VGA cable you bought with your Samsung monitor?

To put it short, both monitors work with the cables that came in their boxes. The Acer cable works for the Samsung monitor and viceversa.

 

When I use any other cable(i bought two of them), both monitors show up as "Generic Non-PnP Monitor", and the image is blurry. It happens no matter the source. I connected them to an HD5670, an R9 270 and a GTX 650 borrowed from a friend. The same issue occurs.

This also happend with an HD Ready TV...so i'm narrowing down the problem to the cables...I really don't understand how they work.

 

If it helps, for the Radeon Cards, I'm using a DVI-D to VGA adapter, because they don't have a VGA output. The GTX 650 has a VGA output. Still the monitors act the same on all 3 cards.

Does it show up like that in Windows or in Catalyst/Nvidia control center? 

My left monitor shows up as "Ancor Communication" in the Nvidia software and as "ASUS VH222" in Windows.

 

And this might be a stupid question, but are the drivers up to date? And did you delete the old drivers?

Yep, did all that, reinstalled Catalyst on the computer with HD5670. I returned the 650 to my friend, i just borrowed it for testing, and I didn't mess with nVidia's Control Panel.

 

This is how it shows up in catalyst

As for the drivers...I uninstalled the monitor's driver and let Windows find it again, but it didn't through the bought cables..

Moreover..drivers don't matter when i switch just the monitors, and let the "good cable" plugged into the PC. 

Could it be that the cable has a "memory" of its own or what?
