Will shortening the VGA extender help with image defects?

Question

Electronics

Hello. In order not to kill the monitor connector, I connect it through a meter extension cable. I just use it for both PC and Set-Top Box. But here's the problem - after adding this meter extension cable to the VGA cable, the image became a little worse - it blurred slightly and at a distance of 5-10 mm some images had barely distinguishable pale "ghosts".
I'm thinking of shortening the extension cord - cut 80 cm between the ferrite rings and solder it in the middle. Do you think it will help? (too lazy to just blindly solder over 15 small wires)

Answer 1

You can buy a monitor switch or KVM, then you do not have to twitch the cords and the quality will not suffer. Now they are not particularly in demand, but I think you can find them on Avito.

Answer 2

The extension cord is too "Chinese", use a normal cable - no extra connections.

Answer 3

in fact, a completely standard problem for vga cables and various VGA adapters.
in bad cables, they saved on shielding or did not connect the shielding to the connector body
at all, as a result, the wires interfere with each other.
in my opinion, the most reasonable thing is to buy a simple signal switch like this D-Link KVM-221
