Asus Rog Swift PG258Q Review
by Lim, February 20, 2017 12:15 am

Asus Rog Swift PG258Q Review - Is it worth to switch from 144 Hz to 240 Hz? A hardcore gaming monitor.



In today's test the new Asus PG258Q "hardcore" gaming monitor with 24.5" Inch, native 240 Hz (without overclock or magic) and a Grey-to-Grey response time of 1 millisecond. Since this is a gaming monitor primarily for fps (fast-paced shooter) and competitive games like Counter-Strike GO, Overwatch and the new Quake, Asus (or rather AU Optronics, which is the panel manufacturer) focuses on a TN model with fastest response time abilities. Thus Asus waives better colors, viewing angles, and contrast against a VA or an IPS panel type gaming monitor. If you choose a monitor like this, you should keep this in mind. Another option is to buy a second monitor for games with beautiful landscapes and atmospheres like Dark Souls or Witcher for example. The G-Sync ranges from 30 up to 240 Hz which is pretty crazy, to be honest. This however only is worth it when your graphics card can offer enough graphic power and fps. Moreover, the PG258Q also supports Nvidia's 3D Vision with the opportunity to play games in 3D. ULMB on this monitor has very much brightness power since the Asus PG258Q reaches around 480 cd/m2 without ULMB. Everything else, as always, in the video review (with English subs) and in this review.

YouTube Video Review



(This was a long article in German before releasing this page in English):

1. Since the article was very long, I cut it and just put all Photos in different slideshows under each topic.
2. When I've started with reviewing monitors, I don't have measuring hardware. So this review doesn't have had that much measurement results as other monitor reviews.

Pros & Cons


- G-Sync with a range of 30-240 Hz)
- Low input lag
- Very bright even in combination with ULMB
- Less motion blur and a smoother gameplay experience at 240 Hz, while the difference is not huge
- Good TN contrast ratio
- USB 3.0 Hub
- Full HD for E-Sports probably still best (while WQHD on 240 Hz with current graphics cards is not really the way to go)
- Very good foot stand and processing (The design, of course, is personal taste)
- OSD and Navigation
- Good TN blacks
- Very nice thin bezels and a clean design at the front


- Homogeneity (brightness distribution) could be a bit better
- LED in the foot stand
- Very aggressive gaming design (foot stand and the back of the monitor)
- Matte panel coating


- TN typical viewing angles and colors
- A bit color banding in darker grey steps
- A tiny bit backlight bleed on the lower, at least on my unit

Hi Im looking to buy my first monitor this week and would like to know which of these 2 monitors(Asus PG258Q or Benq XL2546) you would reccomend. I mainly play Pubg csgo and some dota. I know there are newer 240hz monitors out there now but these are the only 2 available to me. I am currently using a Nvidia graphics card a Gtx 1070 and will upgrade in the future maybe a Nvidia card as well a 2080 ti so I dont know how important that would be to my decision. I've heard both good and bad things about both monitors so I'm kind of hoping for some advice. I could also get the benq monitor about a 100 dollars cheaper not that its a big deal I just want the better of the two to be honest. Thanks any input on this woul be highly appreciated.
