[shri12491]

i bought a lenovo z570 with following config
i5 2410
nvdia geforce 520m 1gb,
4gb ram,750 g hd
now the problem is i cant find graphic card in dxdiag,(desktop-right click/screen resolution advanced setting/)....there it dose not show nvdia.
other things are fine it shows in device manager,
the settings are all clear,bios settings are also clear,tried almost every thing regarding software


nothing much different b/w intel hd and nvdia in many gameshttp://www.thinkdigit.com/forum/images/smilies/icon_neutral.gif



,,,,,,,,,now i had a doubt about hardware defect

use GPU_Z & check for the graphics processor. not all Z570 have graphics card.

Does this model have manual graphics switching system?

Your laptop has a discreate physical switch at the laptop's front edge for switching between discreate Graphics and onboad Intel HD 3000 Gfx based on the application. Use the switch and check again

GT520M isn't much better than the Intel card.
