My display is Panasonic 42" L42U20D full HD LCD TV. When I connect the LCD TV to my HTPC, the fonts are jagged and does not appear smooth. This was happening with the onboard video GF9300 before and even now after changing the video card to a discrete ATI 5450. OS is Windows 7 and HDTV is connected through HDMI.

The TV detects the input signal as 1080/60Hz. Tried all configuration in the ATI Control Panel but no results. I was hoping that upgrading from onboard to dedicated video card with solve the font issue :(

A similar issue is reported here 1080P display problems on Intel H55 based HTPC build

Any suggestions ? Screenshots attached.





















 
This can happen due to two reasons. One is the Overscan correction (Try HDTV Overscanning options from the Catalyst Control Panel) and second is horizontal and vertical scanning (check the TV controls for that)
 
Cleartype is enabled.

The TV has a option 16:9 Overscan - Off/On which does not seem to make any difference to the fonts, only the screen size is adjusted

The ATI Control Center Looks like this
