My system (netbook) specs:

1.6 GHz dual core atom N2600 2 GB DDR3 RAM Integrated GMA3600 GPU Win 7 Professional 32 Bit Daum Pot Player V-1.5

The issue:

I downloaded a 1.33 GB sized 1920 x 1080 HD documentary (file extension: mp4) and it plays without a hitch using pot player. However, when I connected an external display (an LED Full HD 24" monitor) using D-Sub, the video plays fine but the player controls become very unresponsive. For instance, it takes about 40 seconds to exit full screen while playing.

I tried:

Installed/updated all the latest monitor drivers Updated the VGA drivers for GMA3600 No other programs ran while the video played, with most unwanted services and background processes disabled/killed. CPU usage goes only up to 49% when the video plays


What may I do in order to improve the player response/video playback experience? Do I need to play with (or change) Pot Player's default video decoders, etc?

have you tried other media players? VLC? Media Player Classic? – Logman Sep 4 '12 at 2:37
MPC-HC supports hardware acceleration. – Louis Sep 4 '12 at 3:11
thats strange. The monitor should have no effect on the video. The signal is the same no matter what it is connected to. – Keltari Sep 4 '12 at 3:13
@Keltari: You're right, and that's exactly my reason to wonder; and ask here. – xibalban Sep 4 '12 at 4:39
@Logman & Louis: Update: Yes, I've tried those two players and they stutter even on my native 10.1" display. Pot Player, on the other hand, works like a charm. – xibalban Sep 4 '12 at 4:41

Well, I have it fixed now and for the information to all, I changed the default video renderer from EVR to Madshi. The following is the snapshot. 1080p videos now play like honey in a cup of milk: Smooth!!
