Reasons For

Acer G247HYL Benq ZOWIE RL2455 DELL U2412M HP EliteDisplay E242 Head Only
3 Reasons For
$19 Cheaper
The Acer G247HYL costs $149.99, whereas the Benq ZOWIE RL2455 is $169.00 and the DELL U2412M is $184.99.
More Shops Are Selling it
The more stores stock this PC monitor, the greater competition amongst stores to keep prices low.
User Reviews Are Better
The average user review score of the Acer G247HYL is 97% based on 7 reviews, but the average rating of the DELL U2412M is 92% (based on 876 reviews).
5 Reasons For
Bigger Display Diagonal
The Benq ZOWIE RL2455 is a 24" PC monitor, and so do the DELL U2412M and the HP EliteDisplay E242 Head Only. That's 0.2" bigger than the Acer G247HYL (23.8").

The display diagonal is a measure of the size of the monitor. It is measured from one corner of the screen to the diagonally opposite corner of the screen.

A bigger display diagonal means that the screen will be larger and better for displaying lots of content or for seeing the detail in photos and videos.

Read more Read less | Edit
Hugely Faster Response Time
The Benq ZOWIE RL2455 has a response time of 1ms, but the Acer G247HYL is a 4ms response time PC monitor (3ms slower), the DELL U2412M is an 8ms response time PC monitor (7ms slower) and the HP EliteDisplay E242 Head Only is a 7ms response time PC monitor (6ms 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.

Read more Read less | Edit
One More HDMI Port
The Benq ZOWIE RL2455 has two HDMI ports, however the HP EliteDisplay E242 Head Only only has one HDMI port.

We do not know the number of HDMI ports on the DELL U2412M. It is possible that it does not have any HDMI ports.

This indicates the number of HDMI ports the monitor has.

More HDMI ports means that you can plug in more devices (computer, games console, DVD player, etc) to the screen at once.

Read more Read less | Edit
Built-In Speaker(s)
The Benq ZOWIE RL2455 has a built-in speaker(s), however the DELL U2412M and the HP EliteDisplay E242 Head Only do not.

Built in speakers allow you to output sound through the monitor without any need for external speakers.

With built in speakers you can use the monitor like a TV for watch videos to listening to music.

5 Reasons For
1% Bigger Display Diagonal
The DELL U2412M is a 24" PC monitor, and so do the Benq ZOWIE RL2455 and the HP EliteDisplay E242 Head Only. That's 0.2" bigger than the Acer G247HYL (23.8").

The display diagonal is a measure of the size of the monitor. It is measured from one corner of the screen to the diagonally opposite corner of the screen.

Wider Vertical Viewing Angle

The vertical viewing angle dictates the maximum angle at which the monitor can be properly viewed.

A larger viewing angle means that the screen can be watched from many different parts of a room successfully. Conversely, a very small viewing angle means you would effectively have to sit directly in front of the monitor to be able to view the screen successfully.

5% Wider Horizontal Viewing Angle
The DELL U2412M is a 178° horizontal viewing angle PC monitor, and so does the HP EliteDisplay E242 Head Only. That's 8° wider than the Benq ZOWIE RL2455 (170°).

The horizontal viewing angle dictates the maximum angle at which the monitor can be properly viewed.

Built-In USB Hub
The DELL U2412M has a built-in USB hub (as does the HP EliteDisplay E242 Head Only), however the Benq ZOWIE RL2455 does not have a built-in USB hub.

Key Features

Display Diagonal

The display diagonal is a measure of the size of the monitor. It is measured from one corner of the screen to the diagonally opposite corner of the screen.

A bigger display diagonal means that the screen will be larger and better for displaying lots of content or for seeing the detail in photos and videos.

Response Time

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.

Vertical Viewing Angle

The vertical viewing angle dictates the maximum angle at which the monitor can be properly viewed.

A larger viewing angle means that the screen can be watched from many different parts of a room successfully. Conversely, a very small viewing angle means you would effectively have to sit directly in front of the monitor to be able to view the screen successfully.

Horizontal Viewing Angle

The horizontal viewing angle dictates the maximum angle at which the monitor can be properly viewed.

A larger viewing angle means that the monitor can be watched from many different parts of a room successfully. Conversely, a very small viewing angle means you would effectively have to sit directly in front of the monitor to be able to view the screen successfully.

Built-in USB Hub

This indicates whether the monitor has a bank of USBs built into it or not.

A usb hub provides a helpful area to plug in memory cards, charging cables and other peripherals without having to ferret under your desk to plug them into the back of the computer.

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.
