I'm looking for a proper display setup for us sysadmins here and I'm going to be picking out a monitor for us to use.
What features should I look for in a display that are appropriate for sysadmins that spend a lot of time staring at text on a screen?
What qualities are important in such displays?
What qualities reduce eyestrain?
I'm looking at getting a two-monitor setup for us.
Screens tend to be a very personal thing - I don't think there's one universal set of "must-haves". That said, I'd recommend steering clear of the "glossy" displays and pay the extra few bucks for those with antiglare screens. Additionally, make sure that the monitors are VESA mount compatible so that you can attach them to a dual monitor arm if desired.
Honestly, if you want to make your sysadmins really happy, let them choose. Tell them the budget they have to work with and let them do their own shopping.
Also, I find that adjustable ambient light controls are much more critical in reducing eye strain than making sure you have the perfect monitor setup.
I'm not a monitor expert, but I'll offer you the qualities I like in monitors I have to stare at all day:
I use a couple Dell 2408WFP 24" IPS screens side-by-side; these are properly height-adjustable and have a gazillion color controls. Also, the fact that they're IPS panels means they are pleasant to view from most angles.
I fully agree with ErikA's advice to let them shop.
