Overview
Sharper text gives the 27-inch BenQ BL2790QT an advantage over its larger BL3290QT sibling while retaining the same QHD business features. The 2560 x 1440 IPS panel reaches 108 PPI, 350 cd/m² brightness and 99% sRGB coverage, making documents and interface elements cleaner than on 31.5-inch QHD. USB-C supplies 65W to a laptop, and the three-port USB-A hub, HDMI 1.4, DisplayPort input and MST output support a tidy multi-monitor desk. The 110 mm height-adjustable stand and 2 x 2W speakers are practical for daily office use. Its 75 Hz refresh rate is only a small step above 60 Hz, 1000:1 contrast remains ordinary, and 6-bit + FRC colour is not ideal for demanding creative work. Buy it if crisp QHD productivity and daisy-chain docking are important; skip it if you need high refresh, wide-gamut colour or HDR.

HDR & Brightness Reality
No HDR support is listed for the BenQ BL2790QT. The 350 cd/m² brightness is useful for bright offices, but the 1000:1 IPS contrast and absence of local dimming keep dynamic range firmly within SDR territory. Video and photos will look conventional rather than high-impact. The stronger reasons to choose it are its 108 PPI QHD clarity, USB-C charging and DisplayPort daisy-chain capability.

Frequently Asked Questions
01 How does the BL2790QT compare with the BL3290QT? +
Both offer QHD, 75 Hz, USB-C charging and MST output. The BL2790QT is smaller and sharper at 108 PPI, while the BL3290QT provides more physical screen area.
02 Will 65W USB-C power a normal office laptop? +
It is enough for many thin-and-light and mainstream business notebooks. Performance laptops may charge slowly or require their original power supply.
03 Can the BL2790QT drive a second monitor? +
✓ Yes, its DisplayPort 1.2 output supports MST daisy chaining. The computer and operating system must also support the feature.
04 Are the built-in speakers useful for meetings? +
The two 2W speakers are adequate for voices and notifications. A headset or external speakers will provide clearer, fuller sound.
05 Does the BL2790QT suit colour-critical work? +
Its 99% sRGB coverage is suitable for ordinary web content. The 6-bit + FRC panel and lack of published wide-gamut coverage make it a weaker professional colour choice.
