Do you connect your PC to the TV?

I have connected my PC to the TV after a long time (after moving in Nov I had left the TV at my sister as a flatmate had a TV already).

I have noticed a bunch of pixels/points show up all over, the kind of effect you get when you compress a picture too much, not this bad, but to give you an idea:

images?q=tbn:ANd9GcTOm_CK5kaxpAUb8EMzARS

it happens on the desktop, then when in a game it doesn't happen.

I am using a different HDMI cable, as I got my hands on a much longer one... so what I wanted to ask is if by your experience it can be the cable causing it (would it be because is damaged or just the length is enough to cause this?) or some setting in Windows I can change and see?

I remember when I first connected the PC to the TV I did set some additional parameters to sharpen a bit the desktop, and make the contents bigger (without changing the res) but I can't find them anymore, I'm pretty sure was stuff in the nVidia panels and seems with updates the parameters are gone or changed of place... but the end result I have no idea how I could reset the output as if Windows was never connected before.
I wonder if it has anything to do with this artifacts.

Also another problem is that for some reason the desktop never fits the TV properly, every time I have to open the nVidia Control Panel and resize a bit both vertically and horizontally to make the desktop fit. Both TV and laptop are 1080p. This seems to happen when I output " second screen only", if I mirror seems fine. I don't understand why the resolution adjustment is not saved and wonder if is possible to do so.

That's a setting on the TV. You gotta set it from overscan to just scan or whatever it's called.

Thanks I'll try and look for that. Now that you mention, I remember reading about this kind of thing. What I don't understand is why I'm experiencing this problem now, months ago it wasn't happening.
