Connectivity

In terms of video inputs, the Gigabyte GS34WQC is equipped with a pair of HDMI 2.0 ports and a DisplayPort 1.4. Considering its price, it's no surprise that USB-C input is absent.


The monitor has a 3.5-millimeter headphone output.

Power Consumption

The power supply unit is integrated, so there's no external power brick we need to deal with. A simple IEC power cable will be enough to power the Gigabyte GS34WQC. I've used the Meross MSS315 Matter Smart Wi-Fi Plug and the accompanying mobile app to determine the monitor's power consumption at various brightness levels, as well as in Power Saving mode, which it enters as soon as the PC goes to sleep. My power consumption measurements are summed up in the chart below. They were made after resetting the monitor to factory defaults.



Power consumption of the Gigabyte GS34WQC is in line with what we'd expect from a 34-inch ultrawide monitor. The graph also shows us the minimum and maximum achievable SDR brightness (35 and 331 cd/m²), and that the brightness adjustment scale isn't particularly linear. When adjusting brightness past the 75 mark, small steps will noticeably increase the actual screen brightness.
