How see the graphics properties in dell n5110 laptop?

Go to start menu and type in "dxdiag"
It will display all the information you need

My laptop has 1gb graphics card but it shows 1663mb,
then this laptop information is true or false?
Is my laptop contains graphics cadr or not?

did you type in dxdiag? did you go to the display tab? that will tell you whether or not you have a gpu. you have some sort of graphics, just have to find out what kind, odds are its a wimpy integrated if you dont know the specs, but you need to click on the graphics tab under dxdiag
