[mythtv-users] which resolution on a 16:10 lcd?

[come se fosse antani]

Hi.
I've bought an acer LCD 19'' 16:10 aspect ratio; the monitor supports 1440x900.
My primary use for mythtv is watching tv (analogic signal or dvb-t,
PAL) and divx/dvd.
With the 4:3 CRT I had, I used 720x576, but now with the new monitor I
don't know wich resolution use.

Can anyone suggest me?
the lcd is an acer AL1916W.

Thank you
