Not sure if this is the best place to post this, but here goes anyway -
I just bought and connected a 22" monitor to my sony vaio laptop.
Now although it works fine, I notice that when i connect the power cord to the laptop, the monitor starts getting these very faint wavy lines. Sort of like water. They are more prominent against a dark background.
However as soon as i disconnect the power cord from the laptop, the monitor becomes fine again.
The vga cable and power cord are right next to each other.
Why do you think this problem is being caused? Is there any way to correct this?
Rearrange your cables, and make sure they're both grounded to the same pair of outlets or power strip.
