There can often be a surprising difference in the level of picture quality between to seemingly identical monitors. For instance, the Hitachi CM810 is a value-priced 21" display that for all intensive purposes is just about identical to the CM828 we are looking at now, at least from the outset.
Of course the similarities are only bezel deep. The CM828 is higher-end display that sports an even nicer display tube than the very economical CM810. That's not to say the CM810 is not a good display, as it does have it's fine points - you can read our review of the CM810 here .
Now before we get too far off topic, the Hitachi CM828 we are looking at today is a large screen 21" display based on an Invar shadow mask and housed in a cabinet about the size of what a 19" display would typically use. With the CM828 sitting next to my 19" ADI E66 Microscan it's difficult to tell from the rear, which display should be the larger one. Both units are about the same volume.
