Hertz: what they are and how they affect monitors

What is Hertz on Monitors?


Monitors are part of built into computerswhich has been promoted over the years, as well as various interior parts such as processors or video cards, but much quieter, as its achievements did not materialize in big performance improvements or new groundbreaking features.

The fact that the monitors were moving forward was in technologies and capabilities of panels, improve image quality by avoiding problems such as double vision and Cheapening Little by little higher resolutions, and refresh rate, especially the latter with more and more brands, reaching values of 240 or even 320 in some models, but What is the refresh rate? and how does it affect the use of the computer?

Refresh rate Screen Speed Updates Your Content Every Secondwhich is measured in Hertz, or something the same, in the number of times that You can change the contents of the screen (cycles) every second. A high refresh rate will mean that our monitor will change the image FasterGiving a greater feeling fluidity, although there is debate between whether to buy a monitor with a large number of hertz or the eye is able to tell the difference at a high refresh rate, such as 300 or more hertz.

What does it mean to have a high-Hz monitor?

As we said, Hertz is a feature that is associated with monitors, more specifically to its panelwhich will display the image differently depending on the number of hertz it has and the content displayed, as the experience will not be the same when showing the video game as a text document.

There are monitors with Wide range of refresh rates, the most common is 60 Hz, which we will find in the most basic monitors on the market and was especially most common in older monitors. But apart from them, there are monitors with higher values, such as: 120 Hz, 144 Hz, 240 Hz or even values above 300 Hz. Then we can ask ourselves: what difference will we see between some values and others? Well, as we said earlier, it will depend on the usage we give the monitor:

In the “Games” section The difference will be very notable, mainly because the more hertz we have on the monitor, the more images will be displayed on it and, therefore, The smoother the image looks which generates our video card. Especially in games with sudden movements and a lot of actions, The difference will be much more noticeable, because Fast movements will look more natural and detailed, able to change the situation when aiming or reacting to enemies. Although we should not forget that in order to enjoy the high refresh rates, we will need At least one computer capable of generating the same or more frames per second in a gameas we’ll see below.

If we let the monitor use office automation, the excess hertz will be much less noticeable, among other things, because There will be no fast movements, so the only difference we’ll notice is that when you scroll through web pages or move your mouse, the experience will be smoother.

If we are going to use a monitor watch the video, we will notice the difference in hertz as long as Let’s play a video at a high frame rate, which is not too common, with service Such as Netflix, YouTube or Prime Video, give priority to quality and permissionIn front of a video with a large number of frames per second.

Ratio between FPS and Hz

The connection between hertz and frames per second is one of the keys we need to understand to know how they affect monitors and the experience of use in general, since, as we introduced earlier, the connection is direct being FPS is the number of frames generated by the computer and hertz is the number of frames that will be displayed on the screen.

Given this relationship, we may think that we will always be interested in having the FPS and HZ of our monitor. in a 1:1 ratio, or that the same thing, that their values coincide, because in this way We make the most of power what our computer has to offer us. But that won’t always be the case, as the FPS will vary depending on the situation, being able to make them fall below our monitor’s refresh rate. Or it may happen that our computer generate more FPS than the refresh rate of our screenforcing us to waste productivity.

An image showing the “gap” problem that occurs when FPS and Hz do not have the same value.

To solve this problem, several technologies have been developed that allow Communication Monitors and Graphics Cards and so on agree on the number of frames to generate and display To avoid performance loss and at the same time, if performance does not reach the maximum refresh rate, reduce the number of hertz screen to show the FPS that are coming out of the graph. But it’s also that to all of this, They will also fix graphic problems which can be obtained by desynchronizing images, for example, “gap” or flicker, thereby improving the gaming experience at all levels of refresh rate.

Variable Frequency Hz Technologies

There are several frame synchronization technologies in order to match the output of graphics with the refresh rate of our computer, being the most veteran and well-known, developed by video card manufacturers who Free sync in the case of AMD and G-Sync in the case of NVIDIA.

These technologies have been developed over the years, and despite the fact that they are limited. Only maps of each brandwere eventually opened, allowing users NVIDIA uses Freesync on GTX 1000 Series graphics-compatible monitors, as AMD technology was much more popular than G-Sync NVIDIA because of its low cost of embedding in monitors, making it supported in the vast majority of products on the market in all different ranges. In addition, these technologies have undergone several updates, while Freesync has version 2.0 and several levels depending on its characteristics.

But apart from these technologies, there are other free alternatives that achieve similar effects, such as: Adaptive VESA Synchronization, which is an optional feature of Display Port connectors or VPP (Variable refresh rate) of HDMI connectors.

What all of these technologies have in common is that we will have to Check the compatibility of our monitor and our graphics card will be able to take advantage of them, since not all monitors will be able to work with all the graphics, either by brand, technology, or by port and its version, which we use to connect both.

Not only will we need a monitor with many Hz to enjoy them.

So, as we’ve seen when it comes to Hertz and monitors, we usually mean it. refresh rate, which refers to Frames which sends our computer according to the synchronization technology we use.

Therefore, even if it is necessaryAfter a good monitor with a large number of hertz, you will also need a good computer with commensurate power to generate a, which will be displayed, which becomes easier with High Speed Processors and with powerful graphics cards like the latest AMD cards or the new and super powerful RTX 4000 from NVIDIA, such as RTX 4090 and with the technologies they include, such as: DLSS, FSR or the like, which will be able to further improve the performance of a graphics card with artificial intelligence, which is especially useful if we want to play not only on many hertz, but also on many pixels.
