Overview
The black, simpler option is the 23.8" BenQ GW2490C, a 23.8-inch Full HD IPS monitor with 144 Hz refresh and USB-C video input. It suits buyers who want smooth everyday motion but can accept a basic stand. It offers 99% sRGB, 1500:1 contrast, FreeSync, HDMI, DisplayPort and USB-C DisplayPort Alt Mode. The stand only tilts, USB-C charging wattage is not published and there is no USB hub. Brightness is 250 cd/m² and no HDR tier is listed. The BenQ GW2490TC uses the same panel but adds 20W USB-C power and a 150 mm height-adjustable stand. Buy it if you want an affordable 144 Hz office monitor with USB-C video; skip it if you need height adjustment, dependable laptop charging or HDR.

HDR & Brightness Reality
23.8" BenQ GW2490C does not carry an HDR badge, which is honest for this panel. The published strengths are 48 Hz - 144 Hz, 250 cd/m² brightness and 99% rather than peak luminance. Its 1500 : 1 contrast figure remains the main limit in dark content. Buyers should expect consistent SDR presentation and ignore HDR as a reason to choose it.
