Overview
White-finished practicality marks the 23.8" BenQ GW2490TC, a 23.8-inch Full HD IPS monitor with 144 Hz refresh, 20W USB-C and a fully adjustable stand. It suits home-office users who want a cleaner laptop connection and smoother motion. The 150 mm height range, wide swivel, 1500:1 contrast, FreeSync and built-in speakers make it more versatile than a basic office screen. USB-C power is only 20W, so many laptops will still need their charger. There is no USB hub, HDR tier or high-speed DisplayPort standard. The BenQ GW2490C uses the same 23.8-inch 144 Hz panel but drops the adjustable stand and does not publish USB-C charging wattage. Buy it if you want a compact white monitor with 144 Hz and ergonomic adjustment; skip it if you need full laptop charging, USB expansion or HDR.

HDR & Brightness Reality
No HDR standard is listed for 23.8" BenQ GW2490TC. Its hardware budget is directed towards 1920 x 1080 resolution, 48 Hz - 144 Hz operation and the available ports instead. With 250 cd/m² typical brightness and 1500 : 1 contrast, it should be judged on normal desktop and gaming use. HDR video can still play through software, but the specification does not promise expanded highlights, local dimming or a wider luminance range.

HDMI is listed as 1 x HDMI 1.4, while DisplayPort is 1 x DisplayPort 1.2. USB-C is 1 x USB 3.0 (Type-C; upstream; 20W; DP Alt Mode), so buyers can see whether one-cable laptop use is realistic.
