ASUS PG258Q Front

The Asus PG258Q is a 24.5 inch Full HD 1080p, 240Hz, G-SYNC eSports gaming monitor. Now this combination of specifications might seem a bit familiar since we are seeing so many 240Hz releases lately, but considering this monitor is also paired with a 1ms input lag time you will see it is aimed at gamer’s who demand the fastest display.

The monitor is packed with a Full HD display with a resolution of 1080p (1920 x 1080). You can feel improvements on this Asus model with greater color accuracy, but keep in mind this monitor does still have a TN panel. ASUS’s Eye Care technology is once again implemented to allow gamers to enjoy long hours of gaming.

I know many readers may be against TN panels, but ASUS has done a great job at making this one of the best looking TN panels we have tested.

Overall, the main properties are adequately better than before and the ROG Swift is a gamers’ dream come true.

Image Quality

The monitor’s settings offer a number of options controlled from a joystick under the display. A blue light filter helps in reducing eyestrain by making the display colors warmer. This however can also affect color accuracy. Settings also include contrast and brightness, giving you further personalization over the display.

NVIDIA G-SYNC technology proves to be the best for reduced screen stuttering and tearing. The impressive refresh rate of 240Hz gives you an uninterrupted and smooth display system. The Ultra Low motion blur technology functions to remove blurring from moving objects and makes them clearer and visible.

The 25 inch display has a resolution of 1080p as noted before. The clear as a crystal display, which ASUS has taken the time to make as good as possible, will make the watching experience a whole lot better than most other TN panels.

TN panels are notorious for suffering from contrast problems and dull colours. ASUS has done its best to reduce these effects.

The Asus ROG Swift comes with frameless design and includes a unique LED lighting effect. The maximum brightness level 400 cd/m² while the contrast ratio goes up to 1000:1.

Gaming Performance

Perhaps the most game worthy feature in this Asus monitor is the humongous refresh rate of 240Hz. A fast and smooth gaming experience can be guaranteed without question.

ASUS gives a quoted input lag time of only 1ms, which makes this monitor ideal as a professional gaming display. Anyone who plays competitively knows that faster refresh rates allow for a much smoother gameplay and allow more time to react to things happening in faster scenes.

At only 1ms of input lag, this translates to less than one frame lost every second out of 240 total, which is fantastic and will be completely unnoticeable to most people.

Another interesting feature is the Smart Air Vent design. The technology aids the monitor from excessive heating due to long hours of gaming sessions. The customised heat sink works to manage heating and is found to be double the size of heat vents found in other monitors. The Smart Aid also functions for cooling the monitor through its very efficient design collecting air currents within the display monitor.

The frameless bezel-free design is for the exclusive multi display settings for a bigger and more thrilling gamers’ session. The Asus ROG Swift provides you with the perfect gaming experience you have dreamt of.

The GamePlus option on the display controls present some very useful added features such as FPS counters and cross hairs for the games that don’t have them. While the Game Visual has options to calibration settings, which according to Asus are required at times of need.

Features / Design

The inclusion of G-Sync is important to be noted here because the frame rates tend to be increasingly variable above 150 FPS. G-Sync can solve the tearing issues for those with NVIDIA graphic cards. Although this is limited to NVIDIA and not AMD graphic cards.

Another amazing element the ROG Swift offers is the great monitor flexibility.  The three pronged stand of the monitor supports height tilt and pivot adjustments and so you can make angle changes to best of your suitability without actually turning the stand.

The port of the monitor is situated at the back rear. It contains a panel that can too be extracted. The main connect ports include the Display port and the HDMI. Then there are two USB ports 3.0 hub and a 3.5 mm headphone jack which can be used for HDMI and Display Port audio.

One weirdly interesting feature is how the Asus has designed an LED illuminated logo on the base its stand that is displayed on your desk surface. While there is no exact reason or use of it, you do have an option to turn it off through the display controls.

The Asus ROG Swift, has a dimension of 22.3 X 10 X 15.2. The monitor weighs 12.4 pounds. The bezels on the right and left side are both 7 mm giving a slim and smart touch to the monitor.

Final Overview

ASUS has continually led the race towards ultra-fast refresh rates, as evident from when it released the VG248QE a while back. It doesn’t seem all that long ago that the first 144Hz monitors were hitting the market, and now 240Hz is becoming commonplace for TN panels.

We can thank ASUS for being one of the first to release its 240 Hz panel, the PG258Q. If you are interested in one of the fastest ASUS monitors available, and want a variable refresh rate to match your new GPU, this would be an ideal monitor for you.
