Problem with refresh-rate on AIW 9700 Pro. It says 75Hz but is really 60Hz.

[Scott Steven]

Hi, I posted proviously. I seem to be having a problem with my refresh rate
for the AIW 9700 Pro on Win XP. I have installed the latest software/drivers
for the AIW 9700 Pro card. When i go into "Display Properties" and change my
resolution to 1152 x 864, and then went into "Advanced > Adapter" and
changed it to 75Hz. The display however looks like 1152 x 864 @ 60Hz. So I
went into "Advanced > Displays" and it actually tell me 1152 x 864 @ 60Hz
confirming my speculation.

Why does Win XP display properties tell me that I am at 1152 x 864 @ 75Hz ,
where infact I am at 1152 x 864 @ 60Hz (as also onfirmed by the ATI
"Advanced > Displays" tab.

I have been successful at displaying 1152 x 864 @ 75Hz on my old ASUS V8170
DDR Video Card.

Any help appreciated!

Thanks,
Scott

managed to work this one out.

1. Unistalled CCC
2. disabled DDC

Now i am getting my required 75Hz refresh rate at 1152 x 864

Why does ATI control panel's DDC cause such problem?
Is CCC recommended? Seems awefully slow

Now atleast i can uninstall.Net Framework 1.1
