My VeiwSonic A90f+ is rated to support refresh rate of 150 hertz. I have a SONY Vaio. I am unable to change the refresh rate higher then 75 hertz. In control panel, at "monitor settings" under refresh rate. There is a box I am unable to check. Itreads: Hide modes that this monitor cannot display. I want to know how to icrease the refresh rate.
Thanks

first what video card do you have go to the manufacturer and get its new drivers
second if this doesnt wor k go to your monitors manufacturer and look for a monitor driver/.inf file
third if that dont work go to drivers.com or similar site and look for your inf file for your monitor i had to do this because windows has a generic profile for my monitor which works but gave me a similar problem to yours ie... couldnt change refresh rates
fouth if all else fails then look for dxdiag.exe
and overide the default refresh rate *note* this is not recommended by me i had problems with this but it wont screw up your computer as long as you dont set it higher than your video card can support
***** all this works if and only if the video card can support the monitor at the specified refresh rate and resolution ie like some video cards only support 75hz at 1900x1600instead of 150hz at1900x1600******

More than likely your video card cannot support the refresh rate you would like to have. Also like said before make sure you have the latest video card and monitor drivers.
