Overview
Small-workspace buyers can consider the 23.8" BenQ BL2490C, a Full HD IPS business monitor with 144 Hz refresh, integrated 4 W audio and a simple tilt stand. Its 92 PPI density makes text more refined than on the 27-inch BL2790C, despite both models sharing 1920 x 1080 resolution, 250 cd/m² brightness, 1300:1 contrast and 99% sRGB coverage. One source issue needs attention: the listed 0.311 mm pixel pitch does not agree with the stated size and 92 PPI. The 5 ms GtG response is suitable for routine motion, but adaptive sync and HDR are not published. USB-C is recorded as upstream without any charging wattage or DP Alt Mode. BL2490C works best on a correctly positioned desk or VESA arm; BL2490TC is the smarter purchase when height adjustment and portrait rotation are required.

HDR & Brightness Reality
No HDR support is published for the 23.8" BenQ BL2490C. The IPS panel is specified at 250 cd/m², 1300:1 contrast and 99% sRGB, so its expected image is conventional SDR with wide viewing angles. There is no peak-brightness or local-dimming claim. Buyers should value its 92 PPI density and 144 Hz refresh, while treating HDR video as ordinary SDR playback unless BenQ states otherwise.

Frequently Asked Questions
01 What is the practical advantage of 23.8 inches on BL2490C? +
Full HD produces 92 PPI, which is sharper than the 81 PPI 27-inch siblings. The smaller size also fits tighter desks.
02 Why should the BL2490C pixel pitch be checked? +
The source lists 0.311 mm alongside 92 PPI and a 23.8-inch Full HD panel. Those figures do not align and should be verified.
03 Does the BL2490C USB-C port carry video? +
DP Alt Mode is not published. The port is described only as USB 3.2 Type-C upstream.
04 How is BL2490C different from BL2490TC? +
Screen, ports and speakers are the same. BL2490C removes height adjustment and pivot, leaving tilt only.
05 What is BL2490C’s biggest limitation? +
Its fixed stand restricts posture adjustment. Adaptive sync and HDR are also absent from the published specification.
