Reasons For

HP DreamColor Z24 HP EliteDisplay E242 Head Only HP Z24i
2 Reasons For
A Lot Faster Response Time
The HP DreamColor Z24 has a response time of 6ms, but the HP EliteDisplay E242 Head Only is a 7ms response time PC monitor (1ms slower) and the HP Z24i is an 8ms response time PC monitor (2ms slower).

The response time on a PC monitor is a measure of how quickly the monitor reacts to image data sent by the computer's graphics card. Fast response times are particularly important for gamers, who should ideally look for a response time of 8 milliseconds or less.

A faster (shorter) response time is better because fast moving graphics will appear smoother and the gaming experience will feel more responsive.

Running Costs Over 5 Years

PC monitor running costs calculated based on an average of 8 hours of use per day. The running cost comprises the electricity cost when using the PC monitor and the electricity standby cost. Compare all energy saving PC monitors.

Environmental Impact

We have calculated the amount of CO2 that will be generated by running each of these PC monitors for 5 years. We have then converted that into the number of tree seedlings that you would need to plant and grow for 10 years in order to offset that amount of CO2.
