Graphics distortion

Hi,

 

My hackboob starts up with the temperature of between 42-42C and graphics look normal, but as time passes the temp starts to creep up and in about half an hour it reaches between 58-62C idle and stays.

 

I have not much complaint regarding the temperature because I've heard so many stories about "how impossible temperature control is". :rolleyes:

 

As temperature crawls up, graphics starts looking "smudge" or sharp edge of images-be it letters, or photos-get less sharper and at some point it looks as if slowly breaking into pixels. :)

 

I thought it's happening because of high contrast ratio-I've alway felt the display little too bright for my liking,but was not bothered enough to get my hand on it-, so I tried color calibration in the "system preference pane" to lower the ratio, but no improvement. :)

 

So, my question is, is this happening due to high temperature, or poor performance of VGA card?

Or maybe need a proper setting?

 

Could anyone care for advice, please? :D
