screen resolution set-up

I have a client who has recently acquired an LCD screen to use with his note book….

The N/book could not sycronise with the LCD and after considerable trouble shooting i discovered that the adapter settings refresh rate was 48Hz..now when i change it to 60Hz the LCD works perfect untill you restart the settings are restored to 48Hz!!!!

The settings seem to coz problems with the N/Boook screen as sometimes it does not display at all….and the fun+F4 does not work wnen selecting which screen to use

i have installed the latest VGA drivers and utilities…sis 630/730 from www.driverguide.com
