It helps to read the specs of what you have...because the monitor you have maxs out at 1600 x 900. It can't go to 1680x1050 no matter what you try. The best you can do it get a screen that can accommodate your needs.
it helps the read the post correctly dcman3000.
i said i can't get it to run at the native resolution of 1600x900.
i am not trying to get it to run at 1680x1050 - which is the native resolution of the laptop.
geez i wait weeks for a reply and all i get is a dolt that didn't even read the post correctly.
Didn't you say the native for your laptop is 1680x1050, not the monitor you use to view the laptop screen? That would suggest you want the native settings on your laptop reflected on your external monitor, hence my comment. Look at how you worded this:
"have got an HP ProDisplay P201 montior connected to a Compaq 6710b laptop (via VGA connection).
i am not able to select the native resolution of 1600x900.
native resolution of the laptop screen is 1680x1050."
What you SHOULD have said was you are trying to get your laptop screen back to native AFTER you connected it to your laptop...as in presentation setup.
You must be more clear before calling someone a dolt. Wow...
