6 Reasons For
This PC display has an LED display, which is the most commonly found display on PC screens of this age and spec.
We compared this PC display to all the other LCD screens that have an LED Display and we think a cheaper PC screen such as the Benq GW2470H[plb_3034988_price] or you might consider a higher rated PC screen such as the DELL P2314H[plb_1632519_price], and the Asus VS248HR[plb_3103889_price] are also worth considering.
HP Flatpanel Monitors Have Good Reviews
We calculated the average reviews for all HP LCD screens and also specifically for HP medium monitors and found that in both cases HP had good reviews.
Very Low Power Consumption (off)
The power consumption (off)s of LCD screens that have been on the market for around the same time as the Z23n range from 0.005W to 350W, and the average power consumption (off) is 1.6W. At only 0.29 Watts, the HP Z23n has a fairly low power consumption (off) compared to most of the other comparable spec PC monitors that have been available for a similar time to the Z23n.
Quite High Height Adjustment
With a height adjustment of 150 millimeters, the HP Z23n has a fairly high height adjustment compared to most of the other PC screens of a similar type and age to the Z23n. The average height adjustment of flatpanel monitors that were released one year ago is 130mm.
Very Low Annual Energy Consumption
Across all the PC screens of this type and age the annual energy consumptions range from 22kWh to 120kWh. With an annual energy consumption of only 32 kilowatt hours, the HP Z23n has one of the lower annual energy consumptions amongst PC displays of this age.
The weights of similar spec PC monitors that have been available for around the same time as the Z23n range from 2.3g to 79kg, and the average weight is 4.9kg. At only 3 kilograms, the HP Z23n is quite light compared to most of the other medium monitors that are a similar age to the Z23n.

7 Reasons Against
Does Not Have a Built-In Speaker(s)
The HP Z23n does not have a built-in speaker(s). Most of the other similar spec PC screens that have been on the market for a comparable time to the Z23n do have a built-in speaker(s).
We compared all the other PC screens which also have a built-in speaker(s) to this LCD screen and we think the Viewsonic VX2263SMHL[plb_2974753_price] is also worth considering.
Does Not Have a Built-In Camera
The HP Z23n does not have a built-in camera, although it is worth noting that most of the other medium monitors that were released around the same time as the Z23n also do not have a built-in camera.
Like most of the other medium monitors that were released around the same time as the Z23n, the HP Z23n is not 3D.
Does Not Have a Card Reader Integrated
The HP Z23n does not have a card reader integrated, although this is within the context that most of the other PC displays of this type and age also do not have a card reader integrated.
+4 More reasons against
Only 1920 X 1080 Pixels Display Resolution
This PC screen has a display resolution of 1920 x 1080 pixels, which is typical of many medium monitors that were released more than a year ago.
Quite Small Display Diagonal (metric)
The HP Z23n has one of the smaller display diagonal (metric)s (only 58.4 centimeters) amongst PC displays of this age. The smallest display diagonal (metric) of medium monitors that have been available for around the same time as the Z23n is 48cm, the biggest is 89cm, and the average display diagonal (metric) is 64cm.
Fairly Slow Response Time
The fastest response time of medium monitors that have been around for more than a year is 1ms and the slowest is 25ms. The HP Z23n has one of the slower response times (7 milliseconds) amongst medium monitors of this age.
2 Other reasons to consider the HP Z23n
Average Running Costs
This flatpanel monitor has an efficiency rating of A. The Z23n is typical compared to the other 486 medium monitors that came out more than a year ago that we have assessed for running costs. Based on typical usage levels and energy prices, we estimate the Z23n will cost £40 over 5 years to run.
Released Over a Year Ago
It was over a year ago when HP released the Z23n.

Total running cost over 5 years
Running costs for this PC monitor have been estimated based on other similar PC monitors. If you know how much electricity and water the HP Z23nuses then please let us know by entering those figures in the boxes above.
Running this PC monitor over 5 years will generate 0.31 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 8 tree seedlings and grow them for 10 years.
