Video choppy when connect computer to HDTV via HDMI

by outofrange331 / August 30, 2010 11:45 PM PDT

Hello, I have a Samsung multisystem 1080p HDTV (I believe the model number is LA37A550 ) and a new Samsung PC laptop (model number NP-R780-JS01US). Whenever I connect the laptop to the TV via the HDMI cable to play videos that have been downloaded to my computer, they play back very choppy on the TV. They look and play fine on the laptop. The specs for the laptop are:

System Memory(RAM): 4GB
Type of Memory(RAM):DDR3
Hard Drive Type: SATA (5400 rpm)
Computer Hard Drive Size: 500GB
Processor Speed: 2.26GHz
Graphics: NVIDIA GeForce GT 330M
Video Memory: 1GB GDDR3

I initially thought it was the media player, but it happens when I use either Divx, VLC or Windows Media Player.

One thing of note is that there is no choppiness when I contect the computer to the TV via the PC cable pin connect.

Does anyone have any suggestions on how to remedy this situation? Many thanks for all of your help!

Same issue

I'm having this same issue. I'm playing back from a desktop pc that I build to a Samsung TV with 120Hz refresh rate. I hope there's an answer soon. Thanks.

I'm having the same problem as both of you, don't think it's a refresh rate issue, got all the software & hardware updates. I'm stumped.

R. Proffitt, thanks for taking the time to reply. I updated the video driver, HDMI driver and all other hardware I could find that needed updating through Windows Update and my Toshiba product site but the problem persists. Any other ideas? Video is not choppy on my laptop but when I hook it up to my HDTV via HDMI cable it plays smoothly for about 15 seconds then goes choppy for about the same.

"Same problem"?

Remember that your machine may not be the one above. But " Windows Update " rarely gets the right drivers for the machine in the top post.

Be sure to get these drivers the old fashioned way.
