there is no 1366 x 768 the closest is 1360x768 and it looks worse like that
Ok, with the help of my flatmate (with a windows 7 / HD 4850 PC) I think I may have an answer for you:
- Download the most recent version of the Catalyst Drivers and Catalyst control centre if you don't already have them. I just used drivers v 10.3 from
here (for 64 bit windows 7).
- Connect up TV via HDMI
- Open up Catalyst Control Centre (CCC), select the "Advanced" view
- Click on the "Graphics" menu at the top left, and select "Desktops and displays" from the pull-down menu.
- On the Desktops and Displays page, find the icon representing your TV at the bottom left. Right-click on it and selct "configure" from the options.
- Select the "Scaling Options" tab.
- Mess around with the slider until the picture looks good and entirely covers the screen but doesn't run off it.
(-) If that doesn't work - go to the HDTV tab next to it and try to pick one of the 720p or 1080i settings and see how it looks.
Hope that is of some help.
