Those are LG 42" workstation monitors.
Those look like consumer-grade TV's to me.
I'm referencing this page for the "LG 42LB550A" Do I have the right unit? If it is a TV, may I ask why you're choosing a consumer grade TV instead of a pro level monitor? Is it just price or is there some special feature that the LG has?
I'm sure it will display a pretty picture, but my concern would be for durability, esp. in a commercial setting. What's the warranty? In my experience, consumer level TVs aren't rated for continuous duty. Is this a 24/7 display? How long do you expect it to last?
Also, since the displays are not for a video wall, I assume they are to be used by individually by the operator for each workstation. If so what distance will they be from the operator? A 42 inch display with 1080p resolution makes an enormous desktop, and the display may need to be moved some distance away from the user to be comfortable.
