[maemo-developers] Howto configure borderless 4:3 tv-out on n900?

[From: roope.jarvinen at nokia.com]

Hi,

I suggest you play around with xvattr (http://freshmeat.net/projects/xvattr/), which you can use to set various Xv extension attributes, like XV_OMAP_TVOUT_SCALE and XV_OMAP_TVOUT_WIDESCREEN. I'm not sure if you can find it any maemo repository, but you can compile it from source as it is freely available in fresmeat.
