The liyama G-Master GCB3280QSU-B1 model delivered the best picture among the 32-inch gaming monitors with LC display in the test. Thanks to the 165-Hertz refresh rate, games run smoothly across the screen. The switching times are somewhat slow, as is typical for VA, but this did not lead to streaking when tested. The liyama also scores with a USB hub and many adjustment options.

With its discreet design, the iiyama GCB3280QSU-B1 gaming monitor makes a welcome change from bright RGB models and is mainly geared towards the sRGB colour space. However, it is only recommended after prior calibration. Despite good workmanship, there is the problem of a wobbly base, which is due to a production error...
