then get a used 17" crt that works for $5 or so at a surplus auction.
continually consuming more and more resources for the sake of having
the latest and greatest (actually the most hideously broken, in the
case of computer gear) stuff is plain stupid.

no, i don't, because adjusting font rendering to physical dpi is
idiotic. you should always set dpi to 75 so you can use the bitmap
fonts alongside scalable ones, since the bitmap ones look a lot
better.

and it only works for x-based vo's.

alternatively, people with bogus monitors can put this in their config
files for mplayer... :)
