"Generic PnP" Monitor, but Manufacturer Doesn't Publish a Driver (?) - how to fix?

"Generic PnP" Monitor, but Manufacturer Doesn't Publish a Driver (?) - how
to fix?

Installed a Asus VE247H monitor tonight. My Win 7 64-bit identifies it as
a "Generic PnP Monitor".
How can I get Windows to identify my monitor? I looked at the Asus web
site and for the VE247, there is no driver listed, which I'm assuming
means the driver comes with Windows...?
I was quite surprised...expected to need to load a driver.
I went to device manager and tried Update Driver, Let me Pick. If I
uncheck "show compatible hardware," there are a lot of manufacturers
listed, but not Asus. Weird - they do sell quite a few monitors :-)
Do manufacturers release monitors expecting to use the Windows Generic PnP
mode?
The monitor is driving the right display (1920x1080), I just find the
output a little grainy and unsharp. I'm running over DVI on a GeForce 650
Ti card, which is working fine and is current driver-wise.
