LG UltraFine 27UP850N-W 4K Monitor vs BenQ GW2791 27" FHD IPS Monitor

Buy the LG 27UP850N-W if you need sharp text, photo or video work, or a single-cable laptop setup; its 4K IPS panel, 400 cd/m² brightness and USB-C with power delivery are a real step up. Buy the BenQ GW2791 if you mostly browse, write and watch video and want a smooth 100 Hz panel with low blue light and flicker-free backlight. The BenQ is cheaper-feeling in build and resolution; the LG is the more capable display for detail work.

  • Choose the LG UltraFine 27UP850N-W if you edit photos or video, read dense documents, or want one USB-C cable to charge a laptop and carry the display signal.
  • Choose the BenQ GW2791 if you want a comfortable 27-inch office screen for writing, browsing and casual games and don't need 4K or USB-C.

What reviewers say

LG UltraFine 27UP850N-W 4K Monitor

Owners of the UltraFine line generally praise the sharp 4K panel and the convenience of USB-C docking. Complaints tend to focus on the 60 Hz limit and on USB-C power that is not enough for bigger laptops.

What people mention
  • Picture qualityPraisedOwners describe sharp 4K detail and even IPS color for editing and everyday work.
  • USB-C setupPraisedA single USB-C cable for video, data and charging is the feature buyers mention most.
  • Refresh rateCriticisedThe 60 Hz panel is called limiting for gaming and fast motion.
  • Charging powerMixedUSB-C power delivery works for thin laptops but some owners find it short for larger ones.

BenQ GW2791 27" FHD IPS Monitor

Buyers describe the GW2791 as a comfortable monitor for long work and study sessions, citing the flicker-free panel and eye-care modes. They find the 100 Hz refresh and fast response good enough for casual gaming and streaming, and like having both HDMI and DisplayPort. The main reservations are the 1080p resolution at this size and the basic tilt-only stand.

What people mention
  • Eye comfortPraisedOwners say the low blue light and flicker-free modes reduce strain during long work or study sessions.
  • Refresh ratePraisedThe 100 Hz panel feels smoother than the 60 Hz monitors buyers replaced, and suits casual gaming and streaming.
  • ResolutionCriticisedSome owners find 1080p stretched over 27 inches less crisp than they expected, especially for text.
  • StandCriticisedThe stand only tilts, so users who want height or pivot adjustment need a VESA arm.

Questions and answers

Which is better for photo and video editing?
The LG. Its 4K resolution shows fine detail, and 400 cd/m² brightness plus wide color coverage suit color work. The BenQ's 99% sRGB is fine for casual edits but its Full HD panel hides detail.
Which is better for gaming?
The BenQ for casual play, thanks to 100 Hz and 5 ms response. Neither is a serious gaming monitor; the LG caps at 60 Hz.
Is the LG worth stepping up to over the BenQ?
Yes if you read lots of text, edit images, or want one USB-C cable for a laptop. If you mainly browse and write, the BenQ covers that well.
Which is easier on the eyes for long workdays?
The BenQ has Low Blue Light Plus and a flicker-free backlight, which help during long sessions. The LG's sharper text also reduces squinting, but it lacks those specific eye-care modes.
Can I mount either on a monitor arm?
Both support VESA 100 x 100 mm. The BenQ ships with a tilt-only stand; the LG's stand adjusts height and pivots, which matters if you keep the stock stand.
Do either have speakers?
Only the LG has built-in speakers. The BenQ has no speakers, just a headphone jack, so plan on external audio.
