I am trying to use 1920x1080 on a HD monitor. My laptop is Toshiba Satellite M400. It has a Mobile Intel 945 Express Chipset Family and it says "Intel GMA 950" as the chip set on the property panel.
Initially 1920x1080 resolution was not even there. So I followed the instruction at:
After that, I get the resolution on the property dialog but as a I select and apply, my monitor says "Out of Range, 25Hz". I looked at the settings and found that whenever I select 1920x1080, the monitor refresh rate automatically gets 25Hertz (with no other option)
P.S. I am able to use other machines and get 1920x1080 resolution.
