Which is better for office work and reading text?

The HP E27u G5. Its 1440p resolution gives 109 ppi, so text and spreadsheets are noticeably sharper than the BenQ's 1080p at the same 27-inch size.

Which is better for gaming?

The BenQ GW2791, but only mildly. Its 100 Hz refresh beats the HP's 75 Hz, though neither has FreeSync or G-Sync, so both suit casual play rather than competitive gaming.

Can I connect a laptop with one cable?

Only on the HP E27u G5. Its USB-C port carries video and can charge a compatible laptop. The BenQ needs a separate HDMI or DisplayPort cable and has no USB hub.

Which is easier on the eyes for long sessions?

The BenQ lists Low Blue Light Plus and Flicker-Free, which the HP does not advertise. The HP's higher brightness and sharper panel help in bright rooms, so the choice depends on your priority.

Is the HP worth stepping up to over the BenQ?

Yes if you work with text, code or photos and want USB-C docking. The BenQ is the simpler pick for a secondary screen, streaming or light gaming.

Do either support HDR or adaptive sync?

No. Neither monitor lists HDR, FreeSync or G-Sync, so don't expect HDR content or tear-free gaming from either.

HP E27u G5 QHD USB-C Monitor vs BenQ GW2791 27" FHD IPS Monitor

The HP E27u G5 is the sharper, more capable desk monitor: 2560x1440 on IPS gives 109 ppi, and USB-C adds single-cable docking for a laptop. The BenQ GW2791 is a 1080p panel, so at 27 inches text looks softer, but 100 Hz makes motion smoother than the HP's 75 Hz. Buyers of both praise the IPS color and viewing angles; the HP is the better long-term pick for work, the BenQ for a budget home setup.

Choose the HP E27u G5 if you want a crisp QHD screen and a USB-C cable that carries video and charges your laptop.
Choose the BenQ GW2791 if you mainly browse, stream and game casually and want a smoother 100 Hz refresh on a simple 1080p panel.
