So i connect my new tv up to my pc and i have a black border around the picture, not sure why it would do this, the resolution in windows is 1080p and i even have overscan enabled on the tv

Its all hdmi cables

which GFX card do you have - i know it can be corrected via CC

Adjusting Image Position and Size Manually for TVsManually Adjusting Image Size and Position using Underscan/Overscan for TVs

Based on the navigation system contained in the ATI Catalyst™ Control Center window, do one of the following:
Navigation menu—From the display palette on the Desktops & Displays page, click the desired TV, and then click Configure in the context menu that appears.
Navigation tree—From the tree in the Graphics Settings tab, expand TV Properties.
Click Adjustments.
Move the Underscan/Overscan slider to adjust the overall size of the image on the TV. Use this slider to adjust any visible black borders around the edge of the image.
Note: The slider is not available for TVs configured to use a custom or the default optimized timing mode.

Cheers for that, thats exactly what was wrong, CCC was set to underscan, set that feature to 0% and turned overscan off on the TV and its all sorted.

would have taken me a while to find that.

thanks again.

You shouldn't be using overscan/overscan options, you should turn off overscan/underscan completely to get 1:1 pixel mapping. First off enable the 1:1 setting on your TV. This is usually under "aspect ratio" or size settings menu. Then disable any overscan/underscan options within CCC. You should then get a full screen 1:1 image. If not it means you AV receiver is messing with the picture, in which case you'll need to look at the manual and disable scaling options for the input & output in question.
