This impedance matching issue can harm more with basically-VHF signals from eg. 1600*1000 @ 85Hz or more for analog RGB monitors; this requires a lot of bandwidht, making mismatch readily visible. I have a Dell P991 (Sony chassis) operating at 1600x1200 (at 75Hz), and even a little loss of conduction from VGA connector makes ghosting.
