The onboard card might not be able to go that high? That is what I thought at first, but i can set it there, it just doesn't work on the monitor correctly for some reason. And it will only go there with 16 bit color, not 32 bit. i got the drivers from MSI, because it is onboard graphics.
The next issue is that a separate card would probably do this well, but* the case is tiny, and I am fairly certain a card won't fit.
I will try drive sweeper tonight. I am assuming you are talking about this one:
