Adjust image sharpness with 9600m GT?

I was attempting to calibrate the screen

but I can't adjust the sharpness because there is no option to, so is there a different program that will allow me the change the setting?

I want to avoid using a different driver (I'm using 179.48 Beta from the NVIDIA website) unless it will still allow me to use OpenGL in Photoshop CS4

Edit: I'm using an HDX 18 t

 

bump, how are you supposed to calibrate the screen?

 

There is no way of adjusting sharpness of the LCD screen since it's a fixed pixel display... since the connection between the video card and display is digital, there is no analog conversion that will affect the sharpness of the display...

Are you running on a resolution that's not the native resolution of the screen? (i.e. your screen is 1920x1200 natively, but you're running it at say 1680x1050 or even 1440x900) If you use a resolution that's lower than the native resolution of the panel, the video card's scaler will be used in order to "stretch" the image to fill the entire screen... that will result in a slightly blurry/soft image on the screen. The only way to get a sharp image is to run your display at it's native resolution.

 

I'm running at 1920 by 1080... and according to that calibration page i would need to adjust the sharpness, so how would I go about correcting that?

 

You're operating your screen at it's native resolution already. There is no setting that can adjust the sharpness of your screen...

Did you use zoom in your browser? (Firefox will enlarge pictures if you zoom in and enlarge webpages... IE as far as I know doesn't do that...)

 

I think you are misunderstanding me, there is a setting under the NVIDIA control panel that is grayed out called image sharpness, that is what I am trying to adjust, I'm just trying to see if there is another firmware or program that will let me access that slider

 

Oh you mean that adjustment... I think nvidia disabled it for the Geforce 8 series and later (dunno why...). I'm using Forceware v185.68 and that image sharpness slider has been taken out...
