[Solved] Computer is lagging when connected to TV with HDMI cable

Hello,

I have a HP Pavilion DV4-1030en. Specifications:

Intel Centrio 2 2,00GHz
4GB ram
nVidia 9200m GS

So, these are giving the main performance to my machine. I have also a nice Samsung D5000 TV (32" ) FullHD. When I connect my Laptop with a TV, computer start lag. It even doesn't use all of CPU (20-25%, while playing 720p video in TV with 10 fps (Fraps)). I've all latest drivers and everything should work. Using Windows 7.

Thanks for any help, even if it is bad hardware

Are you using HP drivers or one's directly from nvidia.com? I suggest you use the nvidia.com drivers (if not using), like these if using 32-bit:

Or these for 64-bit:

Change your desktop to a Windows 7 Basic theeme vice an Aero theme to see if that helps. Also, what application are you using to display video?

Are you connecting at 1080 or 720 to your HDTV?

That is a lot of pixels for an older mobile GPU. What is the native resolution of your laptop display? I assume video there is ok, true?

Are you driving both the internal and external displays at the same time -OR- just one of them at a time?
