Using a pc with the above graphic card. Use the graphic control panel to change the contrast/gamma, but whenever start the pc again or wake it up from sleep mode, the screen is the same as without making the changes. Please advise, thanks!

Hello boytse,

Can you please post the dxdiag information from your computer please?

I would like to verify some more information about the issue you have.

Thanks for your speedy response. Please tell me what is dxdiag information (I'm over 60, don't know much about computor)? Does it look like the attachment? My Window 7 is in Chinese, but guess the layout is the same.

Hello boytse,

Please note that the support is in English only. However, I would like to let you know what Intel® has developed a new driver for your graphics controller.

It is important to mention that several issues have been fixed on the new release. Due to this, I recommend you installing the new driver.

You can download the driver at the following link:

Hi Kevin.

I have read some feedbacks that the new driver can cause some problems e.g. purple colours...Have no confidence to revert to the old driver if such case arose. But have found out in the Graphics control panel, can save several brightness/gamma...modes which I can choose depending on the room conditions. Satisfied with that. So please treat my request as answered, and thanks a lot for your effort.
