Which is better for a home office?

The BenQ GW2791. At 27 inches it gives far more room for windows and documents, and it has HDMI and DisplayPort for a desktop or dock. The M14 is a travel companion, not a desk primary.

Which is better for travel?

The Lenovo ThinkVision M14. It weighs about 4 lb, folds flat and runs from a laptop's USB-C port. The BenQ is a desk monitor you would not carry.

Which has the sharper picture?

The M14 is sharper per inch: 1920 x 1200 on 14 inches is much denser than 1920 x 1080 on 27 inches. The BenQ wins on size and smoothness at 100 Hz.

Is the BenQ good enough for gaming?

For casual and console play, yes. 100 Hz and 5 ms are a step above standard 60 Hz office panels. Serious players will want a faster, higher-resolution gaming monitor.

Does the M14 work with a desktop PC?

Only if the PC's USB-C port carries video. Many desktops do not, and the M14 has no HDMI or DisplayPort, so check before buying.

Both are built for years of office use, and neither has a clear durability edge. The BenQ's fixed stand has fewer moving parts; the M14's folding hinge and cable are the parts to watch.

BenQ GW2791 27" FHD IPS Monitor vs Lenovo ThinkVision M14

The BenQ GW2791 is a desk monitor: 27 inches, IPS, 100 Hz, HDMI and DisplayPort, VESA mount. The Lenovo ThinkVision M14 is a portable 14-inch USB-C screen that runs off a laptop and slips into a bag. Buy the BenQ for a fixed home-office or study setup and light gaming. Buy the M14 only if you work on the move and need a second screen. Owners rate the M14 well for portability, but its 60 Hz panel and single USB-C input limit it as a main display.

Choose the BenQ GW2791 if you want one large screen on a desk for documents, streaming and casual gaming, with a VESA mount for an arm.
Choose the Lenovo ThinkVision M14 if you travel or hot-desk and need a light second screen that connects over USB-C.
