Hello, I acquired today an Asus 22' inch hidef screen with 1920*1080 resolution. So i tried to see some hi def video from quicktime. Checked the I am a legend 1080p trailer and the bbc motion gallery reel. Link to the second one here: http://www.apple.com/quicktime/guide/hd/bbcmotiongalleryreel.html What i noticed with using quicktime, is that the frame rate varies in different scenes. Sometimes it drops for 1-2 secs to 13-14 fps and then goes to 23-24. This happens a lot of times during the playback. This was when i used boh screen and had the extend desktop or how it is called on it. Afterwards i removed teh monitor and playback the film on the laptops screen with only a part of it showing due to the big window size of it . (1920*108 on 1440*900 screen). Performance was the same. Only thing that was open was messenger for mac in both occasions. Afterwards i quited messenger and things were better but still some drops in performance. Though that a machine of this technology should not have any problems playing it without any hiccups. Anyone else has something similar? I told a friend and tried it on a identical laptop and her was ok and always near 23-24 fps. Any ideas? Can someone try it and post his results?
