Output Laptop to LCD Tv thru HDMI cable...video slowdown

"Hi,

I just bought a new laptop and it has an hdmi output on it. It is only an average laptop so the graphics card is pretty basic- i think its just the standard intel one.

When i connect my laptop to my 42" lcd screen and run it just off the TV, the video plays fine but about every 10 seconds or so it goes jumpy for a few seconds then back to normal.
however if i connect them and run both screens- the image on the tv is much smaller but plays fine. i'm thinking that when its outputting a larger image- that is causing the slowdown cause my graphics card can't handle it.

is there anyway to produce the 42" image without the slowdown?

thanks for the help

There is a chance that it is doing this because of piracy protection built into the software that configures the devices. We've had to deal with this a lot where I work when we make a slideshow for a professional presentation. When you have them both hooked up, do you have the screen settings set up in "Clone" mode? If not, try that. Most times, that takes care of the issue.

Also, try changing the resolution on your laptop to a lower resolution. I know it sounds counter-intuitive, but give it a shot. If you can, drop it down by one tick, then try the TV, turning it off then on each time.
