Review Acer KG241Q 144Hz Monitor | Acer or Warrior?

One of the most requested reviews here at Oficina da Net is finally coming out of the oven, Acer lent us its low cost 144Hz monitor, the KG241Q 23.6 "and we will compare it directly with Warrior Kai, monitor that took everyone by surprise – including us – and it was very well accepted by the public and by us too.

We will touch all possible aspects of the monitor, just as we already do in the current reviews and we will see which model assumes the title of 144Hz monitor with the highest cost x benefit in the Brazilian market, come on.

External Construction and Design

Let's start with the aspects that most call the attention on the monitor, which are its support feet and its side edges that are somewhat large. The monitor really gives the impression of not being very modern because of the more square design, without curves or thin edges like some of its competitors.

Whether beautiful or not with you, the important thing is not to hinder the usability of the product and fortunately it does not hinder anything. Going to the rear of the monitor we find two HDMI 2.0 Inputs (supports 144Hz) and a DisplayPort 1.2 (also supports 144Hz). A DP cable was included in our box, but as our monitor is already in use we are not sure if Acer sent it with us or if it actually comes in the box.

The monitor stand is almost the trademark of Acer in its gamers monitors, we have the two red "claws" jumping forward with the main trunk recessed and all in black. Unfortunately this support only has tilt adjustment, offering no elevation or rotation on the axis, be it horizontal or lateral.

On occupying enough space I would say it depends. At the rear there is a stretch, but this is done to ensure greater stability of the monitor on the table. I prefer the KG241Q's V-claws instead of the round support of the AOC Hero because you can put things there without slipping.

But in fact the only good points of the support foot are the stability and the inclination, besides the Hero is undoubtedly much more complete – height adjustment, inclination, rotation – and the other manufacturers are due at this point.

The monitor's Navigation and Power On / Off buttons are all positioned at the front front with easy access and indented in the monitor housing, probably for design reasons. One thing I think they could do with placing small reliefs to better define the function of each button by touch, because many times I ended up pressing the wrong button exactly because of the lack of it.

There are no textures on the navigation buttons, something I think makes a good differenceThere are no textures on the navigation buttons, something I think makes a good difference

Acer is undoubtedly one of the manufacturers with the most complete menu, and because of that there are big gains that can be made if you do a color calibration on the monitor. There are also FreeSync, DCR options, among other things that I will explain better in the color section of this review.

Oh, before any of you ask, the monitor does have support for VESA mounts and its measurements are 10cmx10cm, so just look at the hole in the support to see if it matches with the monitor and see if it supports at least 4kg.

So for now the monitor does not take any penalty on his note, not least because I do not shoot points for visuals, except if it interferes with the use, which it does not. Now let's talk about the panel in s.

Image quality

This part of the review will be separated into several parts, the most important aspect of a monitor and that is why it deserves the most attention from us. Let's start with color fidelity.


This is the most focused aspect of the monitor, so this time I decided to start the review talking about it. The first game I ran with this monitor with CS: GO, I did it because the game I am most familiar with at the moment and I know every corner of it.

The first thing I noticed was the saturation, which ended up "jumping" the colors of the maps much more. In hell, for example, there are several places that I am used to seeing whites with shades of blue – partly because of my AOC Hero at home – and that on Acer were shown to be more yellow, and highlighting greens too.

Of course, in addition, 144Hz makes all the difference compared to a common monitor and I had no problem with that. After leaving CS, I decided to go to Metro Exodus, and the image quality did not disappoint us one bit.

In Metro Exodus, the story changes a little, clearly a "green filter" in the colors of the monitor and it is very apparent in this game because it contains cold colors and darken, highlighting this tone pull. The good news is that this can be corrected without major difficulties directly on the monitor.

And so, we decided to go to Far Cry New Dawn which has lots of bright colors and that makes monitors with good reproductions shine even more. Once again we like the results we saw and without putting it side by side with other monitors we certainly will not see anything bad.

In general, if you buy the Acer KG241Q to play and follow the few changes we've made directly to the monitor's settings, you shouldn't bother at all. The usage experience was great and we had nothing to complain about within the price and panel limitations it offers. To see what we've changed on the monitor, just look at the session below.

Colors and Contrast

According to the specifications of the panel itself, it covers 72% of the NTSC color aspect, which in theory gives us 100% coverage of the sRGB aspect. Unfortunately we have no way to validate these numbers as we do not have the testing tools.

What can I say that we put it against other monitors certified for 99% DCI-P3, and what can I say that it is far from this level of image quality, which reinforces its very low price which is currently varying between R $ 900 and R $ 1100, depending on the day and store you access.

Again we put it in comparison with other monitors and also with its biggest competitor, the Warrior Kai 144Hz. If you haven't seen his review, it's worth checking out.

We placed the two monitors side by side in two different comparisons: one before calibration and one after, and the results were very interesting, quite different from what we expected to see.

When we place the two monitors with the standard factory settings, the difference between them is clear and the Kai is ahead by a large margin. The colors of the KG241Q are very green, so the monitor looks not only like a green film but also exaggerated.

The contrast is also a place where Kai is ahead when the monitors are original from the factory, something that was totally expected due to the different technologies used in both monitors.

But, as I mentioned before in the review, we always do color calibration to get as close to the real colors of the images, and the one that the Acer monitor goes ahead of. Because of the extensive color configuration menu that Acer provides, it has a lot of flexibility in adjustments and ends up having a much more accurate color reproduction after the internal adjustments.

Adjusting the image just like we did shouldn't take you more than 5 minutes, and to help you out even more I?ll leave you with a short list of the adjustments we?ve made.

  • Brightness 76
  • Contrast 30
  • Black Boost 4
  • Gamma 1.8
  • R Gain 54
  • G Gain 42
  • B Gain 50
  • R Bias 47
  • G Bias 46
  • B Bias 45
  • Blue Light, ACM, Super Sharpness, VRB and Aim Point OFF.

The rest that was not mentioned were kept at default values.

So, to close this part, we could conclude that your factory colors are not very good, there is a great tendency towards green and it is very apparent depending on which environment you are using the monitor. But, after the correct adjustments the colors are much clearer as the contrast improves a lot, making it a great option and competition to Warrior Kai, his main rival.

Ghosting / Fringing

Ghosting is the effect caused by the slow change of pixels on a computer screen, the ideal is that when we take a picture of the monitor, we need to see only the image that is being shown totally static, without any kind of blur or trail behind the image.

As usual, for the video review we use the iPhone XR with slow motion recording and for the photos in this article we use a Canon T5 with 1 / 160sec shutter speed, giving more than enough time for the monitor to display fully static images on all the UFO Test tracks.

    <li class = "col-xs-6 col-sm-4 col-md-3" data-src = "" data -sub-html = "

    Ghosting appears a little, you can see a trace of the alien inside the yellow cylinder at the top of the screen.">

    <li class = "col-xs-6 col-sm-4 col-md-3" data-src = "" data -sub-html = "

    Fringing is a little more apparent, but it does not get in the way of the experience of those who use it.">

And luckily the result is very good for an input panel, there is a bit of fringing in the images, but low enough not to be noticed during the game, while Ghosting is very little and again does not bother.

Even with the good results presented by the monitor, he still ends up being minimally behind the Warrior Kai, but so little that you don't really notice the difference during use, only in tests. If that was a concern for the monitor, then already know that you no longer need to worry.

Input Lag

The Input Lag "test" is always recorded in slow motion to give an idea of ??the monitor's delay. We always use the same environment and the same game to ensure that there will be no gross differences between each monitor.

Again, I emphasize that it is more a visual test than a scientific one and an aspect that I do not conclude – unless it is a big problem – due to the lack of testing equipment. As soon as we have the appropriate equipment we will update all possible reviews.

From the video, everything indicates that the Acer KG241Q has a delay very close to the Warrior Kai, with only one instance being longer than the rest, but this may well be an external influence – like some other program updating in the Background, for example.

We can then conclude that there are no major delay problems on the part of the monitor and that you should not have any problems in competitive games because of that, after all I also played a lot with the monitor and could not notice any problems.


And this review ends with yet another good evaluation of a monitor that has had competitive prices and has not shown any serious flaws during the tests, proving to be the real competitor of Warrior Kai both in price and in quality.

In the end, what will define which one you prefer will be your preference. Want a more modern design and just connect, connect to the PC and play games? Warrior Kai. Do you want a slightly better image as well as a firmer support on the floor and don't care much for appearance? Acer KG241Q.

Acer proved to be a good option between R $ 800-1000, prices that are seen almost weekly in various retail stores and the good part is that this is also valid for Kai, but the reviews still remain the same: IPS panel, bigger color aspect coverage (at least 100% Adobe RGB) and with more adjustments should already be standard at this time of the championship.

But regardless of which one you choose from the current options, you will undoubtedly be well served by the price and you should not regret your choice.


  • Plenty of color and contrast adjustment flexibility, greatly improving image quality
  • Very stable support pad
  • Low price


  • There are no height adjustments or vertical / horizontal rotation
  • Panel still uses TN technology
  • Design gives an old product appearance
  • Factory colors are not very good
