viewing HD content in Pavilion dv9700 series

Hello,
My exact model is dv9750ej (you could search the specs on the internet because I can't post URLs)
When I used to watch movies (xvid format), it was chopped, especially on the fast scenes (the graphic card is nforce 8400M GS), so I upgraded the driver from the HP website, and it seems to be better, although I do see sometimes the chopping..

When I'm trying to play MKV file (720p), the movie lags, and I can't watch it properly. That's even getting worse on 1080p MKV files.
The computer is brand new, and should be able to play those files smoothly. What can be the problem?

Another question: If my screen resolution is 1440 x 900, I know I can view only 720p, but if I will connect the laptop via HDMI cable to my Full HD TV screen, can I play 1080p and see it in full quality?

Thanks in advance for your support!
Tom

 

The slowdowns might be caused by inefficient codecs... some codecs don't make use of hardware acceleration and can cause your movies/videos to be choppy and laggy... You can check and see if your CPU usage is pegged at 100% via Task Manager...

Try using Media Player Classic Home Cinema ( http://mpc-hc.sourceforge.net/)... I use it to play 1080p material and it's pretty smooth....

 

I downloaded the one you told me to, I'm viewing a movie which is 720p, and it's still really lagging. The CPU Usage is between 59-97% and the Physical Memory is 59%

What could be the problem?

 

hmm... what kind of encoding is used for the videos? some codecs can be more taxing on hardware than other codecs... high bitrate 1080p videos can also cause slowdowns as your system cannot keep up with the decoding...

 

I'm not sure which encoders I use, but I use the latest K-lite mega codec pack (4.2.5). My system suppose to be pretty strong (core2duo 2.2Ghz, 2GB RAM, nvidia 8400M GS), so I don't know why it is lagging... How should I check my codecs?

 

Could anyone help me please?

 

I think the H.264 codec used in the K-lite Codec Pack uses FFDShow and that is not the fastest H.264 decoder out there... I used the CoreAVC codec and it seems to be faster... the only downside is that it's not free...

You have to see what codec your movies are encoded on... I know VC-1 encoding is a little more taxing on the system than H.264...

 

Yeah CoreAVC worked well for me. It reduced my CPU usage from 90%+ down to about 30-40% and it is overall not as laggy. Although I installed it along with CCCP, and use ZoomPlayer with the codec installed to watch HD content.
