AOC Agon AG251FZ Review, monitor with FreeSync at 240 Hz

AOC Agon AG251FZ Review (1)

AOC is one of the most experienced monitors brands in the market, because while it is true that they are not as famous as LG or Samsung to set an example, they take as much time or more than they in the market. In addition, recently the company has tried to excel in the market by creating the Agon division, specifically for Gaming , with a series of monitors that have unleashed all its technological potential and that little by little is eating market share to the “big “. Today we are going to present our analysis of the Gaming monitor AOC Agon AG251FZ , a monitor that stands out for its frequency of update of 240 Hz and its compatibility with the technology FreeSync of AMD.

The Agon AG251FZ AOC features a 24.5-inch Full HD (1920 x 1080 pixels) display with LED-VA array, enabling it to have a 240 Hz refresh rate compatible with FreeSync and a response time of Only 1 ms, two input features already make it ideal for the most demanding gamers looking for the fastest possible, and in fact this AOC monitor is one of the fastest on the market. It also counts, and I liked it a lot and I will explain it when I develop the analysis, with multiple features that makes it much more than a simple Gaming monitor, as a base with almost total ergonomics, Flicker Free anti-blinking technology and more.

In short, what AOC intends to offer with this Agon AG251FZ is a top panel of gamers for the most demanding players, so that they can enjoy the maximum of any type of game even at professional level without compromising at any time the performance, and to a Price quite acceptable if compared to the competition.

FreeSync, what does it consist of?

First of all you have to explain a point about the monitors. The refresh rate of these could be called the scanning frequency, or the number of times per second that “asks” the GPU if it has new information to update the screen. If a monitor has 60 Hz for example and the GPU has an FPS rate other than 60 frames per second (FPS), this Tearing effect is produced whose practical representation is seen in the form of images cut horizontally on the screen.

3.- Tearing

This, so far, was solved by enabling vertical synchronization, forcing the GPU to operate at a constant rate equal to the scanning frequency of the monitors, usually 60 in the standard or 120/144/240 Hz in the Gaming monitors. But what happens when the GPU is not able to reach that FPS rate or even running to the fullest?

When the previous situation occurs another phenomenon called Stuttering occurs. The monitor has a fixed refresh rate that the GPU is not able to maintain, and what this produces are small drops of FPS (known as “lag” in the Gamer community) and the so-called “input lag” in the mouse, is To say, the movements that we make of the mouse take more of the account in being represented in the screen.

How AMD FreeSync addresses these issues
We have already told you that the purpose of FreeSync is to make the refresh rate of the monitor is the one that adapts to the capacity of the GPU. For this, all that is needed is that the monitor has an adaptable refresh rate, and therefore not all monitors are compatible with this technology. With FreeSync active, if for example the GPU is only able to operate at 50 FPS, the monitor will adapt to this refresh rate (50 Hz in this case), completely eliminating both the Tearing effect and stuttering and the input lag.

The Advantages of AMD FreeSync
We have already commented several times previously that AMD FreeSync has certain advantages, mainly economic, compared to other technologies (which AMD does not mention but we all know it refers to NVIDIA G-Sync). FreeSync is an open standard, so anyone who wants can adopt it without having to pay for licenses. In addition, it does not require additional hardware (only that the monitor manufacturer adapts the DisplayPort 1.2a standard), so it eliminates an intermediary that in the case of NVIDIA has a performance penalty. In addition, its monitors are (theoretically) capable of adapting a much wider refresh rate, between 9 and 240 Hz (compared to 30-144 Hz G-Sync).
