display problem with Gigabyte GA-785GMT-USB3

[khan sahab]

i am using 19' monitor of resolution 1400*900 with my 9800GT but today i used my motherboard display [Gigabyte GA-785GMT-USB3] as i wanted to use my card with another computer

now my display is stretched and in resolution i cant see 1400*900 settings
instead i am getting these options


the display looks really weird

please help me get a proper display
i am using window 7 ultimate 32bit

Did you try: uninstall nvidia drivers, restart and install ATi drivers?

 

[vantheman5211]

have you installed the gfx drivers for your motherboard?
