How adjust color/contrast on TV monitor-PC hook up?

I have hooked up my LCD TV (Panasonic 32LX700) monitor to my portable PC (HP6-2152nr) via hdmi. The PC has a built-in media card (Intel Graphics Media Accelerator HD.) The monitor's image is too contrasty and the color is off, whereas the PC's images are good. How can I get the same color/contrast on the TV as I have on the PC? On thing I was thinking of was do the corrections, if possible, on a TV mode that I generally don't use. So, when I watch media from the PC, I would then switch the TV mode from its normal viewing mode to the "corrected" mode???

EDIT
I have found one solution and that is when in Screen Resolution, set Display to multiple monitors. This setting has both the TV and the PC screen on and the contrast/color is the same for both screens. However, I would think that one could still control color/contrast with another method(s)???

In the Intel Graphics control panel there are settings for gamma, brightness RGB and saturation. Usually there is an icon in the system tray otherwise you will find it in the control panel. I believe you can set up profiles for different displays......exactly what you need to do.

I understand what you are saying and have used the settings, but I don't recall where one finds setting up profiles. Also, in the Display screen, after doing these settings, and setting the display to the Panny's screen, I failed to note that any changes were made??? Nonetheless, right now, with both the PC screen and the TV screen being active, the picture is just fine.
