The LGL1720B has been out for some time, and wouldn't feature on most peoples wish lists of technology; it doesn't have DVI, it's only a 17" monitor, and by modern standards looks slightly bulky. However, I'm still using mine, for the simple reason that it is a very good monitor who's looks suit the office environment.
The image quality is good, even when connected using a VGA connection, and the native resolution of 1,280 by 1,024 offers plenty of space on screen. It struggles to look good next to my 22" Samsung connected via DVI, but you wouldn't expect it to. Despite being 3 years old, positively ancient in computing terms, the monitor still holds its own in its looks.
Poor elements of the screen include a lack of vertical height adjustment and a distinctly average viewing angle. If privacy at work is an issue, this would be a good monitor for you.
I would never suggest buying this monitor as your first choice monitor, but if you want a secondary monitor for keeping e-mails/outlook/iTunes open on, then this is as good as any, and given its age, is likely available for pennies.
