Test and review ASUS ROG PG258Q: gaming monitor with 240 Hz support

The speed race continues on the monitor market. Not so long ago, manufacturers of monitors were satisfied with the nominal refresh rate of 60 Hz, but in recent years there have been noticeable changes. ASUS ROG PG258Q monitor came to our test lab, providing a refresh rate of up to 240 Hz. Let’s see if you can call a 25-inch monitor the best option for gamers and eSports.

The monitor market has been developing rapidly in recent years after a long period of stagnation. Manufacturers produce displays in the format of 34 inches or even more, and you can purchase even models with a curved panel. In addition, and the game theme manufacturers of monitors also took to the arsenal. We tested a lot of gaming models in recent years, but ASUS ROG PG258Q can be called special. More truly, extreme on characteristics.

Gaming monitors are becoming larger, and the resolution is increasing, but the RG258Q is aimed at hardcore gamers and does not fit into the overall trend. The monitor is hardly larger than the common 24-inch models, and the resolution is not higher. But it is much faster, the refresh rate is up to 240 Hz. There is also support for G-Sync. A high refresh rate will appeal to users who are sensitive to the “braking” of pixels, as well as to cyber sportsmen, who are important every millisecond.

The price of the monitor is not surprising.  ASUS ROG PG258Q can be purchased from 600 euros. That’s about twice as expensive as 24-inch 144-Hz monitors.

ASUS ROG PG258Q: Design

Monitors ROG, previously visited our test lab, always stood out with an interesting and striking design of the case. And the new ASUS ROG PG258Q was no exception. In front of the eyes immediately throws a twisted post. In general, the design reminds the monitor of ASUS ROG PG348 . In addition to the original forms, ASUS added copper elements that nicely contrast with the rest of the titanium rack. The stand takes up not so much space on the table, but the monitor keeps steadily.

The panel itself seems simple, at least in front. ASUS chose a design quite close to edge-to-edge, so the panel on three sides visually almost reaches the edge of the display, resting on a narrow frame. From below the frame is slightly wider, but the overall design does not spoil it. ASUS was able to pack a 25-inch panel into a relatively compact case: ASUS ROG PG258Q is even smaller than some older 24-inch monitors. That will be especially interesting for users planning a game configuration of surround.

Behind the monitor looks more original. Here, attention is drawn to the original angular shapes, as well as the copper circle in the center. In the photo above, the copper accents of the rack are clearly visible.

Side of the 25-inch monitor seems very flat, the case slightly thickens to the middle. Visually the case looks gracefully.

The quality of manufacture, in general, is quite convincing. All gaps are uniform, the body parts are tightly fitted to each other. And the materials are of high quality.

Interface Panel

ASUS offers a standard combination of HDMI and DisplayPort inputs, which can be called quite sufficient. Two USB 3.0 ports are available for connecting peripherals. But to quickly connect the same USB-flash drive, they are located too uncomfortable.

ASUS decided to send all the ports down so they did not break the stylish appearance of the rear panel. But this situation complicates the connection of cables.


Of course, the gaming monitor in 2017 is difficult to do without lighting. But, unlike many competitors, ASUS did not settle for RGB-backlighting.

As in the case of PG348Q, a red ROG logo is projected onto the surface under the counter. The corresponding LED is integrated into the rack with a removable optical filter. In the OSD menu, you can adjust the intensity of the backlight in several steps.

ASUS ROG PG258Q: Ergonomics

Mechanical adjustment possibilities

ASUS asks for a 25-inch monitor a lot, but the Taiwanese manufacturer has added advanced ergonomic adjustment functions. You can change the height of the 25-inch panel in a fairly wide range. That will give the panel a comfortable position, in which you can work long hours without fatigue. ASUS also allows you to adjust the slope of the panel in the range of -5 to 20 degrees, which can be called sufficient.

A good set of ergonomics features is complemented by the possibility of turning the panel into portrait mode. That is, the panel can be rotated by 90 ° and used in an upright position. A convenient function, for example, for working with long documents.

On-Screen Display and Control Buttons

Front of the external appearance of ASUS ROG PG258Q does not violate anything, but for pure design it is necessary to pay with convenience. The buttons are placed on the back panel of the monitor, and their signatures are generally located on the sidewall. Front of the monitor signature is not visible. And working with buttons from the back is not entirely convenient.

ASUS installed four buttons and a joystick. After a certain period of getting used to the buttons you get used, there are no problems. But other manufacturers still install more intuitive solutions, which also do not disrupt the appearance of the monitor.

The on-screen menu is quite typical for ASUS, but it’s good. The menu is clearly and clearly structured, all functions are in place. The set of functions for the game monitor is quite sufficient, although the adjustment of the color rendering in the six axes is not provided. But the target audience of ASUS ROG PG258Q is unlikely to disappoint.

Moreover, there are famous game functions in the on-screen menu. You can display a sight or display the value of fps. There are also various preset modes.

Energy consumption

Given the orientation toward gamers, the TN panel type did not surprise us. This technology consumes slightly less energy than the same IPS panels. In addition, a diagonal of 25 inches and a resolution of 1.920 x 1.080 pixels also lead to a reasonable level of power consumption. With the brightness set at 150 cd / m², the monitor consumed 19.1 watts from the outlet, a convincing level.

ASUS ROG PG258Q offers a record range of refresh rates. We decided to check the dependence of power consumption on the refresh rate. In general, we recommend setting a high update rate only when it is required. The difference between 60 and 240 Hz was 4.6 W.

ASUS ROG PG258Q: Test results

Subjective assessment of image quality

ASUS has equipped a 25-inch monitor ASUS ROG PG258Q panel with a resolution of 1.920 x 1.080 pixels. We get a good screen area, although the difference with the popular 24-inch format is small.For reasons of response time, ASUS chose the TN panel.Many users have avoided TN panels in the past due to the shortcomings associated with this technology, but in recent years the quality of TN panels has improved significantly .

Therefore, the viewing angles of the TN panel are much wider than a few years ago. Although they are not up to the level of modern IPS models. However, the display refers to the gaming models, and the gamer will most often sit directly in front of the panel, so this drawback of ASUS ROG PG258Q can not be called significant. The panel gives a high level of brightness and good contrast.

The color reproduction is also very pleasant. Of course, we do not get such subtle gradations of colors as some high-end displays, but this is noticeable only in direct comparison. It’s nice that the 25-inch monitor is set up neutrally.

In games

But the monitor ASUS ROG PG258Q is still focused on the game sphere. No other monitor in our test lab gave such a high level of refresh rate. The maximum frequency is 240 Hz, but intermediate levels of 200 Hz, 144 Hz, 120 Hz, 100 Hz and, of course, 60 Hz can be selected. Immediately note that for the 240 Hz mode you need a powerful video card, and it makes sense only in the most dynamic games. In them, the monitor works just terrific, the feeling of responsiveness and dynamics in the game is difficult to describe in words. It seems that the game instantly reacts to the actions of the gamer, especially when compared with the refresh rate of 60 Hz. On the other hand, if we compare the monitor by 144 Hz, then the difference will be noticeable, but we would not call it significant. We did not notice any afterglow of pixels on our monitor.

ASUS also added NVIDIA G-Sync technology, which eliminates tearing and other artifacts. In combination with a high refresh rate up to 240 Hz the technology works perfectly, the picture pleases with dynamics and quality.

But ASUS ROG PG258Q is good not only for the high refresh rate in Hertz. We did not find afterglow and other artifacts, the delay in input is not felt.

In combination with the game functions in the on-screen menu, we get a completely convincing gaming monitor.

Brightness, uniform illumination, contrast


In our tests, the TN panel showed a high maximum brightness level. The peak level was 485 cd / m², the average on the panel – 465.9 cd / m². Magnificent values ​​that are more common in laptop displays. With a 25-inch monitor you can work or play in the brightest environments, although in ordinary scenarios such brightness is hardly needed. In a room level of about 150 cd / m² will be quite enough. The uniformity of the backlight is excellent, about 91%. Finally, the contrast is also high, at the level of 1.076: 1, it is rarely possible to reach the same IPS panels.

White point and color rendition

Color rendition

Tests confirm our positive feelings on the quality of color reproduction. The monitor is set to the neutral temperature of the white point – 6.440 K. For the TN panel we get a very high quality color reproduction. The average deviation of the delta E was 1.82, the maximum deviation was 8.86.

ASUS ROG PG258Q: Conclusion

ASUS ROG PG258Q is a modern high-end display. The monitor’s body is of high quality, while it pleases the eye with interesting copper-colored inserts, a stand with an original design and firm illumination from below: the ROG logo is projected under the monitor, but it can be replaced by another template. The 25 “monitor panel has very narrow frames, so several similar models can be assembled into a multi-monitor or surround configuration. The connection set is standard, the ports are hidden in the bottom of the backdrop, they do not break beautiful appearance.

ASUS thought out the options for mechanical adjustment. The panel can be adjusted in height, which will allow you to find a comfortable position. The panel can be turned into portrait mode for working with large documents. We liked the control system less, since the buttons and the joystick are removed to the back panel, and the signatures are on the sidewall. So it will take some time to get used to. The structure of the on-screen menu is logical and convenient, the user will receive a wide range of options, including gaming functions.

As our tests and subjective measurements have shown, ASUS ROG PG258Q monitor will be an excellent option for gamers, but it also suits other scenarios. So we have a convincing universal model. However, the key advantage here is the refresh rate to 240 Hz. If your system is equipped with a powerful video card, then in games you will get excellent dynamics and a sense of responsiveness, which for sure will appeal to hardcore gamers and cybersportsmen. Thanks to the support of G-Sync, you can forget about the tearing of frames and other artifacts. The TN panel proved quite convincing. We got a very high level of brightness, a relatively uniform illumination and a pleasant contrast. In addition, the standard monitor is adjusted neutral. Is that the viewing angles are not as wide as the IPS.

With new ASUS ROG PG258Q introduced an excellent gaming monitor that will take its niche thanks to a very high maximum refresh rate. This specialization seems to us justified, although the price of the monitor “bites”. However, given the high frequency of updates and excellent test results, the price can be called justified. We award the monitor our award “Excellent Iron”.
