Buying Guides

1. The response time

One of two most important things in a computer is the response time, along with the refresh rate. Many people are confused about these things; however, they’re two different things. This is the definition of each:

  • The refresh rate: The refresh rate indicates how many times the image on the screen changes in one second.

  • The response time: The duration from the time the signal is sent until it is displayed on the screen.

The response time is usually as low as 1 or 2 milliseconds, which is a lot shorter than a frametime, defined by the duration a frame is on the screen.

To make it easier, the refresh rate is the number of transitions, and the response time is the transition time. In monitors with 240Hz refresh rate and 1ms response time, it takes 1ms to transit from one image to another, and the image will stay there for another 3ms.

2. Built-in speakers

Is it possible to have a built-in speaker in your monitor? If you said no, then you haven’t heard of the latest HDMI technology. HDMI doesn’t only have support for image signals but audio signals. Thanks to the advancements of the HDMI connections, monitors can now have built-in speakers to eliminate the inconvenience of carrying around the speakers. Instead, use the built-in ones.

3. The resolution of the screen

Along with the refresh rate, the resolution is also important to the screen:

  • 1080p and 720p: To 240Hz monitors, 720p doesn’t seem like a good choice. The reason is 720p is now the old standard which would be deprecated in the future. While 240Hz is considered premium, brands don’t want to do it with a deprecated technology.

  • 4K: 4K is now considered the premium kind of PC monitors. 4K represents the resolution of 3840 x 2160 or something around those values. However, to 240Hz, 4K once again seems impossible, because of the fact that, the current technology is unable to make that kind of monitor.

  • 8K: 8K is now possible in terms of TV’s screen; however, to PC monitors, due to the size, is pretty much impossible at the moment.

3. The size of your monitor

To 240Hz, we have seen several sizes of monitors, fewer than other popular refresh rate: 

  • 13-inch, 14-inch, 15.6-inch: These sizes aren’t usually used for PC monitors but for laptops’ monitors, and they aren’t usually 240Hz.

  • 21-inch: Somehow considered big for PCs’ monitors, but it’s more fit for digital artists, photographers, video editors.

  • 27-inch, 29-inch, 32-inch: Normal people would use monitors this much. These are made for gamers, programmers, content creators, and security supervisors.

4. Additional features

  • HDR 10-bit support: Enrich the pictures by enhancing the definition of the color in the images.

  • Interfaces and ports: Most monitors feature HDMI ports; however, some others support VGA, or DisplayPort. Before buying your monitor, you need to check the specifications of your motherboards, the cables you have.

Energy saving: Monitors use not much electricity. Some monitors are certified Energy Star, which determines that the monitor is likely to be one of the most power-efficient.

The Best 240Hz gaming monitors

1. Alienware 25 AW2521HF 24.5 inch

As you all have known, Alienware is a good place for all the gaming lovers. Alienware 25 AW2521HF 24.5 inch is one of the products that lie in the ecosystem. The gaming monitor offers the resolution 1080p Full HD, with the native refresh rate of 240Hz, which flashes itself 240 times in a second. 

A true premium 1ms response time is ideal for any gaming lovers, when the screen can respond to the signal in less than 1 thousandth of a second. The IPS panel contributes to helping the images look crystal clear, from every angle possible. The AMD FreeSync technology is a perfect solution for the smooth and comfortable gaming experience. 

Finally, what doesn’t seem important is the cooling. Cooling is not considered a major problem for monitors; however, it is focused by Alienware. It has ventilation systems in all the sides, including the top, bottom, and rear size of the monitor, thus, it will not feel as hot as usual monitors.

  • 25 inches

  • 1080p

  • 240Hz refresh rate

  • AMD FreeSync

  • Cooling design

2. LG Electronics UltraGear 27GN750-B

LG Electronics UltraGear 27GN750-B is the ultimate gaming monitor on the market. It features a 27-inch screen with the native refresh rate of 240Hz. That means you would put another 120Hz of pressure on your CPU compared to a normal 120Hz affordable gaming monitor. 

Obviously, the design of a flagship should be stunning: It is 3 sided borderless designed, along with the 27-inch widescreen, makes you feel like looking at a real scene in real life. It’s made compatible with NVIDIA G-SYNC, which works in the companion with NVIDIA GeForce GTX, to provide the most smooth images possible. 

HDR 10 is also built-in for improving the image quality. The stand can be adjusted vertically, tilted forwards and backwards. Finally, it has the standard 1080p resolution.

  • 1080p resolution


  • 240Hz of refresh rate

  • 27 inches of screen

  • HDR10, which we don’t see in other monitors

3. ASUS TUF Gaming VG279QM 27” HDR

The next candidate in our list is the ASUS TUF Gaming VG279QM 27” HDR. This monitor isn’t curved; however, it has the incredible 280Hz refresh rate. We have extensively tested this monitor, and what we have seen blew our minds. 

Sometimes, you even forget that it is a monitor, but imagine it’s something happening in real life. The native refresh rate is 240Hz, and 280Hz is the overclocked value. The Asus Extreme Low Motion Blur Sync, working perfectly with NVIDIA G-SYNC, removes all the blurring, ghosting, and tearing of images on your screen. The resolution is the standard full HD 1080p, supported by two ports: two HDMI 2.0 ports. A 15-backward and 5-forward tilting option in degree would be perfect for you when you change your sitting position. 

As a bonus of a premium monitor, the refresh rate is adjustable for your advantages. HDR10 is available, and the monitor is certified DisplayHDR 400.

  • 27 inches, which is large.

  • 280Hz of refresh rate.

  • 1080p resolution.

  • Two HDMI 2.0 ports.

  • NVIDIA G-SYNC compatible.

  • VRR (variable refresh rate).

  • 15 degrees tilt backwards and 5 degrees tilt forwards.


1. What is DisplayHDR 400?

DisplayHDR 400 is the certification for certified monitors that can well display HDR images. HDR was introduced back in 1993 when computers were not as popular as they are now. HDR gamut represents colors using a 10-bit unit instead of the RGB color system currently used. That’s why we get much richer, and more contrast with the HDR screen, and it improves your viewing experience.

HDR monitor can significantly improve your playing experience. However, it will put pressure on your GPU and the screen’s processor as well.

2. What is the voltage rate of my monitor? Does it work with US 110V

The voltage rate of a monitor is surprisingly not 220V or 110V. The rate is usually 19V, 12V, or 21V, which is a little bit inconvenient, compared to the old-type 220V monitors. However, it is safer for the users. 

In order for 220V and 110V to work with your monitor, the brands all have included an adapter which converts the current from 220V or 110V to the voltage rate that works with the monitor. Therefore, if you replace your monitor adapter, it is advised to buy from an official store instead of regular stores, because if the rate is not correct, it might damage your monitor, and you’ll lose the warranty.

3. How do I mount my monitor to the wall?

To mount a TV on the wall, you first need to find out the mounting size of your monitor. Monitors usually use the same mounting size, so you don’t need to worry much about this. After ordering your monitor mount, use a screwdriver to fasten the screws into the monitor, and hang it on the wall.

There should be more detailed instructions on how to do that, which would come with both your monitor mount, and your monitor itself.

4. How do I set up my new monitor?

To set up your new monitor, follow these steps:

  • Step 1: Connect your monitor to the computer. There are two ways to do this: connect to the default motherboard’s port, or to the graphics cards’ port. If you connect to your graphics cards’, it might require you to change some settings for your monitor to work. Secondly, you have to decide the port to use. HDMI ports support great resolutions with the controlling options and audio, while VGA represents the old standard of monitors, which would be more compatible with different types of monitors.

  • Step 2: Plug in the power cord. Most monitors provide a default adapter to convert the traditional civil 220V or 110V to 19V or 12V, which is safer and what the monitors use. If you don’t have the adapter or have lost it, it is recommended to buy another from the official repair center, or in the worst case, buy the adapter with the exact voltage rate.

  • Step 3: Power the monitor on, set the resolution and change some settings if needed. Then, you’re all set.

5. My monitor doesn’t work?

Firstly, you should know why your monitor doesn’t work. Check with the cheat sheet below. If you’re unsure, take it to an official repair center for checking out.

  • Use the wrong voltage rated adapter: In this case, the monitor would either be broken or not turned one. You will be likely to see nothing that indicates the working state of the monitor.

  • The computer doesn’t support a compatible resolution: This usually happens because of wrong settings. In this case, try resetting your monitor or graphics card settings, or reinstall the operating system. If they didnt work, you need to take your computer or your monitor to a repair or warranty center.

  • The cable is broken: You recognize this error by seeing the message “No source” or “No signal”. Replacing  the cable is needed at this point. There might be a possibility that the cable is too long, that the power supported by the card is not enough to deliver the signal. In this case, using an HDMI adapter is advised. 

6. What is ultrawide?

Ultrawide is a definition of aspect ratio. Aspect ratio is usually defined by the number of pixels width divided by the number of pixels height.

  • 1:1 aspect ratio: The beginning of aspect ratio, which is like no aspect ratio at all

  • 4:3 aspect ratio: Typically used in old CRT monitors. The most popular resolutions are 640x480 and 1024x768

  • 16:9 aspect ratio: Standard definition right now. The most popular resolutions are 1366x768, 1920x1080 (2K), 3840x2160 (4K), or 7680x4320 (8K)

  • Ultrawide: Defined by anything that is wider than 16:9. Some aspect ratios are called ultrawide include 18:9 on some 2017 phones, 18.5:9, 19:9, 20:9, 21:9, or even 25:9.
