Graphics card is a nVidia Corporation G73 [GeForce 7600 GT] (rev a2) LCD monitor is a HP LP2475w (which is internelly a LG-thingy according to the hidden service menu... Both connected via DVI with the original cables which came with the Monitor. 1920x1600 only offers 60Hz. I really dont want to reduce the resolution because it was one main reason fpr a new monitor and running a LCD not at its native resolution impacts clearity of vision as far as I know... > _______________________________________________ > MPlayer-users mailing list > MPlayer-users at mplayerhq.hu > https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users > -- Please don't send me any Word- or Powerpoint-Attachments unless it's absolutely neccessary. - Send simply Text.
