The HP EliteDisplay S231 has a better display type than most PC screens of this age and spec. This PC display has an LCD display, whereas most medium monitors that are a similar age to it have an LED display.
We compared all the other PC screens that have an LCD Display to this LCD screen and we think the Acer DA220 ($240), and the Benq RL2460 ($235) which has better reviews is also worth considering.
If the display type of this LCD screen is too bad for you then you might want to look at the Philips 221P6 (LED and higher rated) or the Philips 221B3LPC (LED and cheaper), or the LG 23EN43 (LED and cheaper).
What does "display" mean?
