Been looking at 19" LCDs myself. You're right, the L90D+ is an 8bit monitor, but I must say I hate its chassis.
Personally looking at the Viewsonic VP930B
. I love its color. Given that I always shift positions and can't be bothered readjusting the monitor, this comp is good for me. I have personally looked at both the mentioned monitors and this one, and I find that you DON'T have to look straight on to get a good pic, unlike the other 2.
Of course, it comes at a premium.
But then again, check out some mods you can do to the Hyundai, I've seen one you can do, if you dare (hence solving the bad looking chassis problem). Plus, I have my own speakers, and prefer my monitor to be speaker free. You might want to consider that.
Stay clear of the 930BF. Apparently its the same panel as the 930B, just with different electronics. Goodness knows what they sacrificed to get that 4ms response time
And the same would go for the 940BF too I assume.
