Overview
Compact desks benefit from the 23.8" BenQ BL2490TC, a Full HD IPS business monitor pairing 144 Hz refresh with a height-and-pivot adjustable stand and built-in speakers. At 92 PPI, text and interface detail are finer than on the 27-inch BL2790TC, while the 250 cd/m² brightness, 1300:1 contrast and 99% sRGB coverage remain otherwise closely matched. The supplied sheet lists a 0.311 mm pixel pitch, which conflicts with the stated size, resolution and 92 PPI and should be checked before publication. Motion reaches 144 Hz with a 5 ms GtG response, but no adaptive-sync standard is given. Its USB-C port is upstream only in the listing, with no charging or video mode confirmed. BL2490TC is the practical choice for adjustable compact workstations; BL2490C keeps the same panel and connections but removes height and pivot adjustment.

HDR & Brightness Reality
The 23.8" BenQ BL2490TC is not listed with an HDR format or certification. Its 250 cd/m² brightness, 1300:1 contrast and 99% sRGB coverage set ordinary SDR expectations for office work and media. No peak-brightness or local-dimming data is provided. The panel’s stronger selling points are its compact 92 PPI density, 144 Hz refresh and adjustable stand, not expanded HDR highlights or black depth.
