1080P and XPS1210

I'm not sure where to put this thread since I have no idea what's been causing my problems. Anyhow, I have a XPS1210 (T7600 2.33GHz, 2GB, Geforce Go 7400) and it's having problems playing certain 1080P videos. It's fine at playing the 1080P samples on MS and Apple, but it's having trouble playing ripped HD-DVD and Blu-ray content. It shutters A LOT and it seems to have insufficient CPU that's causing it. However, I'm pretty sure that a t7600 Core 2 is able to play these kinds of videos. I am aware that the Geforce Go 7400 in my laptop is hardly a good GPU, but isn't playing HD video more CPU dependent than GPU? Does anyone know of a solution to this? Thanks

 

what format are the rips in?

 

uh, the m1210 screen resolution is only able to display 720p, 1080p is a waste

 

assuming you are using an external 1080P screen. If so try setting the 1080P monitor as the only monitor active, and turn off the the internal laptop screen. Also have you tried newer drivers? Also what program are you using to play the content and what format are you encoding the videos in?

 

The reason I asked about formats is that some formats are more demanding than others, and on top of that, the 7400 has rendering support for some formats. As vengance said, if you have both an external display and an internal, you will run out of video RAM/GPU processing power.

 

Its not that, the Dual Monitor setup can use much more resources when being played on the secondary monitor. Not sure why, but its been like this since the geforce 6 days.

 

I think that's so there is more power for the "primary" monitor, my old 9600 used to get half the FPS if a second monitor was enabled. I'm sure if they put the effort in the power could be dynamically shared between displays, but they probably think that not enough people use dual monitor to make it worthwhile.

 

Are they x264 encoded? What codec are you using? ffdshow? coreAVC?

 

wow! I didn't expect these many replies. Anyhow, the videos are in mpeg2, mpeg4 format, which are in either .ts or .mkv containers. I know that my screen doesn't support 1080P, but I'm output these to a 1080P TV. While doing that, I disabled everything I possibly could, including the inbuilt monitor.

 

But did you make it your primary monitor? and did anything work?

 

Yes, I made it my primary monitor and the video played... just not smoothly. It'd shutter frequently

 

In don't know about MPEG2, but MPEG4 is really demanding, getting 1080p MPEG 4 to run smoothly on a PC without hardware decoding in the video card is near impossible.

 

Well, how should I go about getting hardware decoding on my video card? I know Purevideo from Nvidia can handle MPEG2, but what about MPEG 4?

 

Purevideo is the only thing you have for video rendering, I know that the 8x00 series have MPEG 4, but I can't remember about the 7x00s.

What codec do you use?

 

I use the mpeg 4 codec that came with K-Lite Mega Pack, and I haven't the faintest what is it and Purevideo Platinum for MPEG 2. However, the problem is that most of my videos are encoded in MPEG4. I tried playing the videos on my quad-core desktop and they still used more than 50% of the CPU power! I'm pretty sure playing HD videos doesn't take that much power. Besides, MS only recommended a P4 3.0Ghz for HD-DVD or Blu-ray playback and I'm pretty sure that however slow my Core 2 laptop may be compared to my desktop, the former should still be able to play these videos fine.

 

I just tried a trial of Cyberlink Power DVD Ultra and it seemed to work much better than the previous codecs.However, I get this constant and nauseating flickering when I play videos in full screen. It's fine otherwise.

 

Ok, now I've managed to get rid of the flickering problem with an update, but now, the it's selecting the wrong language. For some of my videos, they have multiple audio streams all embedded in one file. However, Cyberlink always selects the wrong one! I don't see an option in it to adjust it as the "select next audio stream" is blanked out. Any ideas?

 

I can't get my laptop to even output 1080p from the VGA port. What did you do to get it to work? I max out at a res. other than 1080p. It says it's outputting it, but my TV says its sending out something other than 1080p.

BTW, did you make sure your output monitor is set to a dot to dot mode? Does it verify the resolution?
