The main interest of these two 27-inch diagonal gaming screens lies in their particularly high refresh rate of 520 Hz, with a response time of 1 ms. They therefore come into competition with the model that ViewSonic plans to present at CES in a few days. But where the ViewSonic model benefits from an OLED panel, these PG27FFX2A and PG27FFX1B must for their part "make do" with an IPS panel with a more classic WLED backlight. Fun fact: this refresh rate is only achievable under Windows 11: the previous version of Microsoft's OS being a priori limited to "only" 500 Hz.
Two almost identical gaming screens
Another difference is that these two Phantom Gaming screens from ASRock must be satisfied with a Full HD definition while the ViewSonic screen can a priori go up to WQHD. Both models are also VESA DisplayHDR 400 certified and support AMD FreeSync Premium technology. They offer 94% coverage of the DCI-P3 color space and 123% of the sRGB gamut, with viewing angles of 178°. The contrast ratio reaches 1000:1, for a brightness peaking at 400 cd/m².
The connectivity is also identical between the two models: there are two HDMI 2.1 inputs, a DisplayPort 1.4 port, a headphone output (two small 2W speakers are also integrated), two USB 3.2 Gen1 Type-A ports and a USB 3.2 Gen1 Type-B port. On the other hand, only the PG27FFX2A can be adjusted in height by 10 cm, tilt (-5° to +20°) and rotation (-20° to +20°). It is also the only one of the two models to integrate a WiFi antenna, a relatively anecdotal feature in practice.
The manufacturer has not yet announced a price for these two 27-inch 520 Hz IPS gaming screens, but if we base ourselves on the price of the AGON AG276FK which has extremely similar characteristics, we can expect a bill that will be around 600 euros.
