Nvidia Graphics Setup - Overscan i think it is?

[Conrad11]

Hi there,

I am not sure which setting I want to change but here is the problem:

I have a Dell Laptop (XPS M1530). It has a HDMI output which i have plugged into my TV.

Now I can set it up so that the resolution is fine (1366*768). The problem is that some of the picture is not showing on the screen because the picture is "too big", so I need to set it up so that it starts the desktop at the point 10 pixels down and 10 pixels across (example)....

...I hope someone understands the question

....anyways, does anyone have a guide for doing this, I am running a Nvidia graphics card.

Thanks.

you should set it to 1360x768 for 1:1 pixel mapping.
You will end up with 3 pixels each side not being used, you wont notice!

What does 1:1 pixel mapping do/what is it?

Also, the resolution of my display is 1366*768 though so surely setting it to 1360*768 isn't 1:1.

EDIT:

I think i have figured out my initial problem
