Same summary

The AOC Q27G4ZR monitor with a 27-inch diagonal and QHD resolution offers a balanced combination of size and image sharpness, which is especially suitable for users looking for more screen space and multitasking. The Fast-IPS panel and high refresh rate of 240 Hz stand out as key advantages for more demanding gamers, where responsiveness and smoothness of the image play a decisive role. However, due to such a high refresh rate and fast response time, it will probably be less suitable for users who value color accuracy or professional graphics work - in these cases it makes sense to consider additional options. It is worth noting that larger monitors like this require enough desk space and an optimal viewing distance for eye comfort.
