I doubt that. You cannot adjust the screen resolution of client system - that would be a big security hole, which if allowed!
What you can do is, adjust your browser according to the screen resolution using Javascript.
You can always do something like this:
if ((screen.width < 1024) && (screen.height < 768))
{
alert('Your screen resolution is less than 1024x768; this site is best viewed at 1024x768 resolution!!!')
}
