F.A.Q - TV-technic and cabling

 

 

 

Which is the best resolution for movie watching?

For the playback of movies you should use the modes with the highest picture quality. This is hte case in the following modes:

Conexant Chips:
PAL: 768x576 Fullscreen (800x600 is ok, too, but cuts more of the picture)
NTSC: 720x480 Fullscreen

Chrontel Chips:
PAL: 768x576 Fullscreen (800x600 is ok, too, but cuts more of the picture)
NTSC: 768x576 Fullscreen

Philips:
PAL: 800x600 Fullscreen
NTSC: 800x600 Fullscreen

The flicker filter should be set to the lowest position. Then the picture has best sharpness.

 

Why is the screen size not infinetely variable?

That is not possible because of technical reasons. The used VGA-TV converter chip (BT86x) can only produce certain sizes. Also many size adjustments produce a bad picture quality or the aspect ratio is wrong (the picture is strechted). So there are only three sizes at the moment.

 

Why do I lose a bit of the picture at the borders of the screen in fullscreen mode?

 

In contrast to a monitor a TV set always works with overscan. That means, that a bit of the picture is hidden at the borders of the screen. This technic is used to avoid any black borders under any condition.

Modern TV sets have an overscan value of about 7-9%, so 7-9% of the picture are lost at the borders. However, the fullscreen mode produces exatly the same picture size as a standalone DVD player would do.
