Why do I have to scale my video for my large screen tv?

[techs]

I haven't much experience using anything except a computer monitor. I hooked my computers up to my 52inch Sony LCD HDTV. On one computer the screen is fine at 1920x1080. I am using an ATI 4850 pci express card thru an HDMI cable.

However, my new build, which is a core i3 on Windows 7 correctly uses the 1920x1050 resolution, but the screen size is too big. In other words my taskbar is below the bottom of the screen and I can't see it. Same problem exists both vertically and horizontally. I fixed the problem by going into the Intel Graphics tool and reducing the scaling.

My questions:
Is this the result of my tv's overscan?
Is this normal?
Is there some other way to fix it that I am missing?

Thanks

This happens when my TV is set to "16:9", have to change it to "Just Scan" for it to fit correctly. Your TV probably has a similar setting.

Honestly the best place to look for answers on this one is avsforum.com They have a set of HTPC forums but I would recommend looking in the flat panel forums and searching on your specific TV. There are many TVs where you just can't get 1:1 from your PC, it's stupid but true.

I honestly don't know but I always thought of it as normal. I use multiple different ATI cards off my same TV and on all of them I've had to set them up for underscan the first time around. Except going through HDMI, that seems to work right off the bat. Is your new i3 build also going through HDMI, or is it on a different input?

I have a "Full Pixel" setting and so far it seems to work and fixes the problem, though once I had to cylce thru the inputs on the tv because the overscan came back.

And, yes, I do have it going thru the HDMI.

This is totally normal though I am curious why your TV is 1920 x 1050 instead of 1920 x 1080. It's likely that your ATI card was sending a underscanned/overscanned signal which automatically fit your TV while your intel gpu is just sending a normal 1920 x 1080 signal.
