What is the typical power consumption and thermal design rating (TDP) of the BenQ GW2790TC 27" FHD 144Hz monitor during standard use?

The BenQ GW2790TC typically consumes around 20 to 30 watts during standard office or home use, which is quite efficient for a 27-inch IPS monitor with a 144Hz refresh rate. The manufacturer doesn’t list a specific thermal design power (TDP) since monitors don't usually require one like CPUs or GPUs do, but the low power draw means it runs cool and doesn’t need active cooling. If you’re pushing the monitor to its limits, like running at 144Hz with higher brightness settings or using power-hungry USB-C accessories, the power consumption might creep up slightly but won’t impact heat dramatically. Compared to gaming monitors with higher resolutions or faster panels, this one stays relatively energy-friendly while maintaining good performance.

Does the BenQ 27" monitor have built-in speakers?

Yes, the BenQ 27" monitor has built-in speakers with a power output of 2 x 2W.

What is the refresh rate of the BenQ 27" monitor?

The refresh rate of the BenQ 27" monitor is 144Hz.
