Why does my computer not support higher resolution

[Loumas]

Hello,
I have a Toshiba C855 with a max screen resolution of 1366x68. The graphic card is Intel(R) HD graphics 3000.
My new LG 21,5" screen supports 1920x1080 screen resolution.
What can I do to get the 190x1080 screen resolution. It seems the driver are up to date.
Do I need to buy and installa new graphic card? I dont even know whether that is possible.
And - is there a big difference between the resolutions? I use the new monitor for photo editing.
If you could point me in the right direction I would be very grateful. Oh, I am running Windows 7
Thank you.

Your hooking up a laptop onto a normal desktop screen? If so which cable are you using?

You might need to tell it to use external monitor, to unlock the higher resolutions.


The HD 3000 supports 1080p at 60hz, you might need to lower the monitors refresh rate before bumping up the resolution.
