Connecting Laptop to TV question?

[AndyH97]

Sorry if I sound dumb but this is really bugging me.

I have connected my laptop to my TV through a HDMI cable to extend the displays. However, I noticed the display on the TV was very small. Therefore, I went into 'Intel Graphics Properties' and changed the TV resolution from 1920x1080 to 800x600, and the picture became larger! How is this possible? Surely the more pixels in the display, the larger the picture?

Go back to 1080 and look for an overscan setting to adjust.

Ok I'll try that, do you have an answer as to why it appears bigger on the TV even when the resolution is smaller?

Uh, nope.
