Complete Guide To 240Hz Monitors (120hz Vs 240hz)

Complete Guide To 240Hz Monitors (120hz Vs 240hz)

Monitors advertised as 240hz refresh rates are interpolated; this means that they use internal hardware to make the 120hz monitor display like it is actually 240 Hz. In this article, we will discuss the complete guide to 240Hz monitors (120hz Vs 240hz).

Refresh the rate refers to how many times per second your screen can update itself, so more Hz = higher fps. It is measured in hertz (Hz). The average person should experience no noticeable ghosting at 60hz, however, if you are an avid gamer or want the best picture quality possible then look for a monitor with 144hz (not available on all displays) OR one with 240hz.

What Do The Refresh Rates Mean?

The higher the Hz, the better would be your gaming experience or watching movies. You can have a look at the recommended monitor Hz for different devices here- Monitor Hz Guide.

You might take things further and overclock your monitor to increase its Hz but you should know that not all displays allow it and that overclocking voids the warranty as well. You should also do some research on how to overclock monitors correctly. 

It is important to keep in mind that Monitors advertised as 240hz refresh rates are interpolated; this means that they use internal hardware to make the 120hz monitor display like it is 240 Hz.

What Does 240hz Refresh Rate Mean?

Complete Guide To 240Hz Monitors (120hz Vs 240hz)

The refresh rate is the number of times per second that your monitor updates itself. More the Hz, the better will be your gaming experience or watching movies. Refresh rates can vary between 6hz for basic monitors to 240hz on high-end ones.

As mentioned above, the average person won’t get any advantages with 60Hz but gamers and people who use their PC for work purposes might need a higher refresh rate of 120, 144, or even 240Hz to avoid ghosting of fast-moving images/videos.

What Are the Advantages Of Having A 240Hz Refresh Rate?

The higher the refresh rate is, the more fluid images will be displayed. This means that you won’t experience any kind of lag or ghosting when playing high-end games or watching videos in high resolution. 

Also, it improves your overall PC performance. Most modern CPUs have a maximum refresh rate of 60 Hz which means that they can send no more than 60 frames per second to your monitor for rendering purposes. 

In short, you need at least 120 Hz if you want to benefit from a healthy frame rate and fluid animations, but 144 Hz is ideal as there’s no screen tearing nor stuttering involved whatsoever.

In the past upgrading, your monitor was difficult and pretty expensive so most people were bound to the refresh rate of their monitors which was 60Hz. However, now there are more options available with prices being considerably lower than before.

Would You Experience Any Ghosting With A 240Hz Monitor?

Ghosting is when an object on the screen leaves behind a trail of pixels, effectively appearing as multiple images. It has nothing to do with the refresh rate but more to do with frame withholding and response speed of your monitor which means how long a pixel takes to change from one color tone to another. 

This also depends on many other factors such as the GPU you are using or if there’s V-Sync ON/OFF. In short, you won’t experience any kind of ghosting, at least not noticeably, even if you have a 60Hz monitor after upgrading to a 120/144 one for gaming purposes.

How Much Does A 240 HZ Monitor Cost?

As already mentioned in this article, prices vary according to different factors such as size and features included like adaptive sync technology. 

Most high-end models go up to $500 however, if you’re an average gamer and just want to improve your graphics performance, it would be enough to upgrade from 60Hz to 120Hz display.

How Much Do Refresh Rates Matter For Gaming?

One thing that is important to mention here is that 60Hz monitors were not always the standard. There was a time when people had 25Hz monitors, then 30Hz ones which were considered high-end until this technology became cheaper and more accessible for average gamers too. 

Since there are no real differences between different refresh rates in terms of gameplay (all follow the same rules), it’s safe to say that all numbers above 60Hz can be considered good choices for gaming since they will make the game run faster but still smooth, without stuttering or screen tearing.

Can You See The Difference Between 120Hz And 240Hz?

The truth is that you won’t notice any difference, at least not to the point where it would impact your gameplay. The human eye can only see somewhere between 20Hz-30Hz tops which means that refresh rates above are wasted money for most gamers.

However, if you want to experience what 240Hz has to offer whether watching 2D or 3D videos without screen tearing, fast-moving images/videos will be displayed smoother and more fluid than ever before since each pixel only refreshes itself 120 times per second instead of once.

Does DisplayPort 1.4 Support 240Hz?

Yes, it does. Display port 1.4 which was introduced in March 2014 supports 240Hz and even 480Hz (not yet available for gamers). However, unlike HDMI 2.0a which also has this feature, Display Port is still less popular among manufacturers of gaming monitors so until this situation changes there’s no way of using such high refresh rates with your PC.

Is G-Sync Or Free-Sync Supported?

High-end models like Acer XB321HK and Asus PG248Q both include Adaptive-Sync technology which allows them to synchronize monitor refresh rate with Nvidia & AMD graphics cards so you won’t experience any screen tearing or stuttering while playing games or watching movies. Even older GPUs starting from the Kepler series will work nicely with these monitors without any problems.

However, if you are an owner of a high-end graphics card like Nvidia’s GTX 980 or AMD R9 290X with Free-Sync technology but your monitor doesn’t necessarily support it (see this list ), there is another solution for you- BenQ XL2730Z which does come with Free-Sync and can be adjusted to 100-240Hz refresh rates, depending on what game you’re playing or the response time of your TN panel.

Do I Need A Xbox One S To Play Games On 240 Hz?

No. Just because Xbox One S comes equipped with a 4K UHD Blu-ray player capable of HDR playback at 60fps, this has nothing to do with the speed of your computer which is the only thing that matters smooth gameplay. Once you upgrade your monitor to a 240Hz one and play the game, you’ll see it running faster than ever without any problems.

Do TN Or IPS Panels Matter For 240hz Monitors?

TN panels are more common among all different types of display devices used for gaming such as TVs or monitors. They generally have a 1ms response time (how fast each pixel can change colors) and that’s why they’re widely spread among gamers since their main job is to create high refresh rates which in turn lead to fast-paced movements during gameplay when reacting quickly becomes critical.

IPS or In-Plane Switching technology offers better color reproduction compared to TN ones but unfortunately, its response time is much slower at around 16ms so if a monitor is built on this technology, do not expect it to work well at 240Hz.

Is It Worth Buy A 240hz Monitor?

Complete Guide To 240Hz Monitors (120hz Vs 240hz)

If you have a high-end graphics card then absolutely! If your computer can play the latest games at 120fps-144fps without stuttering or lagging, think of how fast it would be when running them at 240 FPS. 

Sure, 60 FPS looks nice and smooth with no tearing but there’s just something special about really fast-paced gameplay which means that faster monitors are always desired by gamers.

What’s The Difference Between 144Hz & 240Hz Monitors?

The screen tearing occurs when monitor frames are drawn out of sync with GPU ones so instead of seeing the top half from one frame and the bottom half from another one, the image/video you’re watching is drawn like a jigsaw puzzle. What speed of monitor can prevent such situations? You guessed it, 240Hz.

Monitors below 144Hz are called “regular” ones and generally speaking older models with less than 120Hz refresh rate should be avoided since their performance isn’t really worth the price that wasn’t paid for them (even though they look nice). However, if you buy a brand new 240 Hz monitor then no matter what screen tearing will not be an issue for at least the next couple of years.

144Hz vs 240Hz Input Lag

There is no such thing as input lag when it comes to 240Hz monitors since all processing and calculations are done by GPU instead of a monitor. Once you connect your PC to a 240 Hz monitor and start playing any game, there won’t be any difference in responsiveness and smoothness compared to older 144 Hz ones.

However, if we’re talking about input lag here then I have something not-so-nice for gamers who own TVs with a 120Hz refresh rate- your TV’s built-in processor takes around 16ms to create each frame which means that it has a higher input lag than most of the gaming monitors. 

So yes, once you increase the refresh rate of your display device from 60Hz up to 144Hz or 240Hz, there will be a slight improvement in the responsiveness and smoothness of your gameplay.

What Do You Need To Run At 240hz?

As I’ve already mentioned above, you need to either buy a monitor with a 240Hz refresh rate or connect your computer to a TV that is capable of 120-240 Hz input. 

If we’re talking about Xbox One S then this console can output up to 120 fps (frames per second) but that’s nowhere near as fast as required by games like Counter-Strike: Go or Overwatch where 240 fps are needed for silky smooth movement during gameplay.

FAQs: Complete guide to 240Hz Monitor

Why 240Hz Monitor Is Better Than 144Hz?

Just like how there’s no difference in input lag between two similar monitors but one of them has a higher refresh rate, the same situation applies here. Yes, 144Hz is just as fast as 240Hz ones when it comes to responsiveness or smoothness during gameplay.

But once you display more frames per second, animation becomes way smoother which is what matters for gamers. The main advantage of buying a 240hz monitor is that you’ll never have any problems related to things like stuttering, tearing, response time, etc.

What Is 240hz Input Lag?

There is no input lag when it comes to modern gaming monitors since all processing and calculations are done by graphics card rather than the screen. So if you see someone saying something like “X monitor has high input lag” then they simply don’t know what they’re talking about. 

If there was any input lag in monitors, it can only be found in TVs that have built-in processors (rather than GPUs) so make sure to avoid any 120/240Hz TV s with 60Hz mode (or called game mode).

Is A 240hz Monitor Worth The Price?

That depends on how much you play video games. For example, if you’re a casual gamer who plays less than 5 hours a week then there probably won’t be any noticeable difference when buying a 144Hz monitor

However, if you’re a competitive gamer and spend most of your time in front of a PC then going with 240 Hz is the only logical choice since it will allow you to have more frames per second without any problems related to tearing or stuttering.


As time passes, the price of new technologies is getting lower which makes them accessible for average people too. Thanks to that nowadays you can get both your TV and PC monitor with higher refresh rates than 60Hz without spending a fortune on it. 

However, while some models go up to 240 or even 144Hz, others start at just 60Hz so if you want to improve your display’s performance, be sure to check what your device (monitor) is actually capable of before buying anything else.
