I bought the Hauppauge Colossus cap card for its HDMI input. (I don't have the pc specs to run a real capture card.)

I will be recording my laptop's gaming using my desktop (with cap card).

My Question: Will I need to also buy a HDMI splitter or is it possible to mirror my screen. Or will that be too much for my laptop to handle?

I guess the real question is: How much does mirroring your screen impact the video card's performance?

Edit
My laptop has one HDMI output on it.

Ok. After doing some more research on the subject I've found that mirroring your display will have a serious impact on your video cards performance.

So... if your computer is barely playing the game on high settings, it's not possible.

What about if you watch your game on the desktop's monitor through the capture software and disable the laptop's monitor. It would introduce a bit of lag though. –  TuxRug May 13 '11 at 17:48
