iiyama has always been tops for monitors.
I bought two S702GT 17in models in 1999, one for me and one for my son as a Thank You at the time.
Both have been used for thousands of hours and are still going strong - not even had to alter the settings for brightness, contrast or to adjust the screen size.
Checks on colour balance etc still reveal them to be spot on.
The only problem - nd it is a minor one - is that the right hand side of the display gradually fills in a gap over five or 10 minutes to the edge of the screen.
Both do this, so it must be a common fault. It took a little while to twig that the original settings had to be set after a longer delay than normal for the monitor to properly warm up.
Incidentally, iiyama's support (at least at the time I used it at the time the monitors were acquired) was spot on.
