[MPlayer-users] Re: [-] monitoraspect

[Gianluca Interlandi]

Many thanks for all your commentaries! I was not counting with it. Just a
few words about my monitor. I have a Philips Brilliance 180P2 with a
resolution of 1280x1024. Its physical dimensions are roughly (measured
with a ruler) 35.7:28.7 [cm] giving a ratio of approx. 1.25:1. Thus my
monitor has square pixels. Only if I use the flag "-monitoraspect 1.25"
the movies are played correctly.

I have checked the entry in X86Config:

	DisplaySize  320 240  (-> 1.33:1)

Maybe I should change it to the correct values, but I don't see a need at 
the moment.

Best,

Gianluca
