The Iiyama Prolite XCB3494WQSN is an excellent all-around monitor. Thanks to its perfect calibration right out of the box, it is ideal for all everyday tasks and especially for workers who need faithful colors. On the other hand, its sufficiently reactive 120 Hz panel makes it a good playmate, not necessarily for competition, but it should satisfy a large part of the players. Finally, the presence of a USB-C port delivering 65 W and a keyboard/mouse switch (KVM) makes it easy to switch from a laptop to a desktop PC while maintaining the same keyboard/mouse combo, enough juggle work and play with ease.
The Asus TUF Gaming VG279QM is an excellent gaming monitor aimed primarily at performance enthusiasts. Although originally calibrated, it lacks a bit of contrast and a USB hub to be perfect. It is today the most responsive IPS monitor on the market and remains the only one able to compete with the most powerful TN models. It is a product of choice for cyberathletes. The others will gladly turn to the AOC 27G2U, which is a little less responsive and limited to 144 Hz, but also less expensive.
