Affordable gaming monitor update: AOC G90-series review

The competition is getting heated in the budget segment



With the new G90 series, AOC introduces a number of gaming monitors that can easily be included in the market segment. The G2590VXQ will appeal to the gamer with a really low budget, the G2590PX is a very complete model for those who want 144 Hz but which does not burn a hole in the pocket. Only the G2790PX cannot be placed very well - the price difference with the lower end of the luxury segment is relatively small (approximately 60 dollars) and FullHD 27” is not very popular with the connoisseurs. A model with a VA panel (as present in the Agon line) can probably count on more appreciation.


Also looking at the test results, the 144 Hz G2790PX is the weak brother: the lowest response times at optimal settings, but also most overshoot; the lowest checkerboard contrast, the lowest uniformity of black. However, the very low colour deviation and grey error are an upside, and the white uniformity is very good. We can imagine that if the price falls well below 360 dollars you can switch to this model (and the lowest price in our Price Comparative is already close to it).


The G2590VXQ seems to be positioned directly opposite the G2530HSU-B1 of Iiyama: the same panel, almost the same price. If we put them opposite each other in a comparison table, the new AOC wins on the following features: one HDMI input more, and a larger FreeSync range (30-75Hz vs. 40-75Hz), while the G2530HSU has a USB 2.0 hub (for gaming this a little less important). In the test results it is neck-to-neck: Iiyama has lower response times, but AOC has less overshoot. In terms of consumption, the tables turn. AOC has a slightly lower minimum brightness (but still too high), Iiyama has a much better black and therefore contrast - with AOC you have to adjust manually a little bit. However, the brand in focus, delivers better uniformity, certainly in white -  only to lose again to Iiyama in terms of viewing angles, albeit with only the toes over the line. Iiyama wins again, convincingly, in terms of colour deviation. We rewarded the G2530HSU with a Great Value award some time ago, and that goes to AOC as well. For gaming this model may have a slight advantage, while Iiyama is a favourite in terms of calibration. In both cases you get a very complete entry-level monitor for a very modest amount of money.


Then the G2590PX, the entry-level 144 Hz model. With an average price of just 340 dollars, it is one of the cheapest in its class. The direct competitor is once again Iiyama, in the form of the G2488HSUB3. However, it is also nice to make the comparison with the considerably more expensive MG248Q by Asus. This is a somewhat older model based on another fast panel. AOC wins in terms of features with ease: a larger FreeSync range than with Iiyama, and more connection options than with Asus. At the response times it is again neck-to-neck between Iiyama and AOC, but the latter clearly has less of an input lag. Speed is the only aspect where Asus has clearly better results, which given the approximately €70 to €80 higher price, is also understandable. AOC then convincingly wins on power consumption and (maximum and minimal) brightness, Iiyama - on contrast, albeit close. The GB2488HSU-B3 also has the better results in terms of uniformity, but the G2590PX has the best viewing angles. In terms of colour reproduction, the win goes to Iiyama, with AOC as a good second and Asus as a straggler at a distance (in all fairness, Asus makes up for it with a separate sRGB mode). Long story short, the AOC G2590PX can not only easily compete with the older, somewhat more expensive competitor, but can also easily compete with the significantly more expensive monitor of the market leader in this segment. As far as we are concerned, this makes the G2590PX an Excellent Choice.
