I have a Viewsonic 19" PF795 flat screen. It is the PF790's big brother and I got it for the same price from Onvia 8 months ago. I see Viewsonic get slamed a lot here but I can testify mine is SUPURB in every way. At high resolutions of 1024 x 768 and over 100mzh all my games crystal sharp and the color is nice, that is where the PF795 shines over the PF790. Please also consider that your video card will influence greatly any monitor. A low performance card will keep the monitor from doing its best. I'm running mine with a GeForce DDR...NV20 later I hope.
Also consider for a little bit more a 19", the extra real estate makes a BIG difference.
I can recomend Viewsonic. I'm very pleased with mine with everything I do.
