Overview
More screen area is the defining benefit of the 31.5-inch BenQ BL3290QT, a QHD IPS business monitor with USB-C docking and daisy-chain support. Its 2560 x 1440 panel delivers 93 PPI, 350 cd/m² brightness and 99% sRGB coverage, giving offices a spacious canvas but softer text than the 27-inch BenQ BL2790QT. USB-C provides 65W charging, while three USB-A ports, HDMI 1.4, DisplayPort input and MST output support a practical multi-monitor workstation. The stand adds 110 mm height adjustment and swivel, and 2 x 2W speakers handle calls and system audio. Motion performance remains basic at 75 Hz, and the panel uses 6-bit + FRC rather than native 8-bit colour. The large chassis also needs more desk depth and width. Buy it if workspace and USB-C daisy chaining matter; skip it if crisp pixel density, high refresh or wide-gamut colour is the priority.

HDR & Brightness Reality
The BenQ BL3290QT is an SDR business monitor with no HDR support. Its 350 cd/m² brightness is useful in normal offices, but the 1000:1 IPS contrast and lack of local dimming cannot create deep blacks or bright highlight separation. For buyers, the relevant advantages are the large QHD workspace, USB-C docking and daisy-chain output. HDR video should be viewed in SDR rather than treated as a strength.

Frequently Asked Questions
01 How sharp is QHD on the 31.5-inch BL3290QT? +
It works out to 93 PPI, so the workspace is large but text is less crisp than on the 27-inch BL2790QT. A longer viewing distance helps.
02 What can the BL3290QT USB-C port handle? +
It carries video, data and up to 65W charging. That is sufficient for many mainstream business laptops, though high-power mobile workstations may still need their charger.
03 How does daisy chaining work on the BL3290QT? +
The monitor includes DisplayPort 1.2 input and MST output. A compatible computer can send video through the first monitor to a second display.
04 Is 75 Hz useful on an office monitor? +
It makes cursor movement and scrolling slightly smoother than 60 Hz. It is not a substitute for a 120 Hz or faster gaming display.
05 Why might the BL2790QT be preferable? +
The 27-inch sibling uses the same QHD resolution, giving it a denser 108 PPI image. Choose the BL3290QT when physical screen size matters more than text sharpness.
