I've never owned one, but have seen a few. They are known as one of the best monitors on the market. So your purchase is actually pretty secure I'm sure.
And to the other guy. Yes the NEC is a great monitor. I have it infact, and the FE991SB, but the Liyama line of monitors do seem to be in the "Higher end" of monitors.
Or so it was when I was buying my first monitors a few years back.
I'm sure you're golden on your purchase.
Oh, and as far as I know, You're Video cards options is how you'll jack your Refresh rate up. You will most likely have to do this manually. I always have had to.
But hey, I'm a newb. I just was posting cause I knew a 'lil'something about what you were asking.
Take care.
