graphic problems

i went to my friend's house today, he has nba live 07 too and his graphics seemed like so real, it was like in nba 2k7, so i went to his options, and did the same thing in my computer, but it didnt work!! does it depend on the monitor?? i mean he has that thin monitor, and me i have a big one, so can graphics depend on that>? or is there a patch to get u nba 2k7 graphics on pc?? it's just so real and nice!! yeah and one more thing, when i go to "detail settings" i want to turn on the lightning, but its like grey color and i cant change it, its desable. do u know what i can do about it??

hope u guys to anwser my questions, thanks in advance!!!

Need to upgrade your graphics card. That would be he difference between the performance.
