the Iiyama VM 1451 19" FST is still a CRT monitor. i do not know what FST means but i would guess it stands for flat screen technology. FST is just another matketing ploy like TFT which i would guess means true flatscreen technology. it means the screen is flat.
I have never heard of either of these brand names. you should also consider NEC 19" monitors, they are cheap and they are known for good quality. I think NEC is made by mitsubishi, at least thats what it says in the driver manufacturer field for my NEC.
