Need the right configuration to set the standards for the config.txt file to set an PAL LCD 1080p.
I have tried hdmi_group set to 0, to use the preferred group.
That tweak gave me sharp text although the LCD output in unscaled mode gave me a small output box screen in the centre of the LCD.
I also set these parameters that gave the same output, small centre box in unscaled LCD mode. In auto-zoom LCD mode the image did fill out the screen, although I get the sense that it leaves out to much when viewing a web page for example, just as it does in unscaled LCD mode.
sdtv_mode=2
hdmi_group=2
hdmi_mode=82
The correct configuration for a 16:9 PAL 1920x1080- 60Hz are:
sdtv_mode=2
sdtv_aspect=3
hdmi_group=1
hdmi_mode=16
disable_overscan=1
