Let me clear my views....
If you want to do more graphic works.
Resolution,Refresh rate and Dot Pitch
are important factors.
KDS can perform 1600*1200 resolution at 85 Hz refresh rate while
others can only only perform 75 Hz at same resolution.
KDS also has .24mm Dot Pitch, which provides better
text and graphic display. HOWEVER, the quality of
this product is concerned. My friend burned his KDS within 3 months.
If you don't care about Flat Screen, you can buy Hitachi or SamSung,
which gives you average refresh rate
1600 x 1200 at 75 Hz
1280 x 1024 at 85 Hz
But Hitachi has Superfine 0.22mm horizontal/0.14mm vertical dot-pitch.
and Samsung has 0.26 mm dot pitch.
I bought ViewSonic PF790 last night to replace my 17" Viewsonic PT775.
I have used ViewSonic PT775 and GS775 for 4+ yrs. They never had problems
at all. Personally, I believe ViewSonic has better quality comparing to KDS
and it's $35 dollars cheaper. Although PF790 doesn't have very low dot pitch
on its CRT (0.25 mm center, 0.27 mm at corner), I can always work some small
graphics at center of screen since it's 19" monitor.
Hope my explaination will help you guys decide what monitors to buy.
