Connectivity

The ASRock Phantom Gaming PG34WQ15R3A is equipped with a single DisplayPort 1.4 input and a pair of HDMI 2.0 inputs.


Next to the video inputs is the 3.5 mm headphone jack.


On the rear side of the stand, you'll find a single USB Type-C port. It's used to power the integrated RGB lighting system and the front-facing PG Mini OLED display. It serves no other purpose; it can't transfer a video signal or power to a connected device. Finally, the rear side of the stand has a pair of RP-SMA Wi-Fi antenna connectors. To utilize the 7 dBi Wi-Fi antenna integrated into the stand, you'll connect these ports to your motherboard's RP-SMA connectors by using the supplied extension cables. They're 1.5 meters long, so that's the maximum supported distance from your monitor to your PC case (unless you buy aftermarket cables, of course).

Power Consumption

The ASRock Phantom Gaming PG34WQ15R3A uses an integrated power supply. I've used the Brennenstuhl PM 231 E power meter 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.



The ASRock Phantom Gaming PG34WQ15R3A has an expected power consumption for a 34-inch ultrawide monitor. What's slightly unusual is how the panel behaves when adjusting the brightness setting in the OSD. From 0 to 70, the actual screen brightness (and, thusly, power consumption) is fairly slow to rise from 83 cd/m² (25.6 W) to 182 cd/m² (32.9 W). In the 70-100 brightness range, every single step increases the actual panel brightness by around 10 cd/m². With brightness set to 100 in OSD, you end up with an actual brightness as high as 490 cd/m². In that state, the monitor consumes almost 60 W of power.
