LG UltraFine 27-Inch 4K UHD IPS Monitor vs Dell S2721QS 27" 4K Monitor

Buy the LG UltraFine if you connect a laptop: its USB-C port carries video, data and up to 90W of charging over one cable, and its stand adjusts in height, tilts and pivots to portrait. Buy the Dell S2721QS if you want a plain, dependable 4K screen for a desktop PC, console or streaming, with AMD FreeSync smoothing games and a 4 ms panel. Both are 27-inch 4K IPS screens with HDR playback, so the picture is close; the LG adds color depth, a wider gamut and the docking features, while the Dell is the simpler, more widely owned set.

  • Choose the LG UltraFine if you work from a laptop and want one USB-C cable to charge it, show 4K video and run two USB devices, plus a stand that pivots to portrait.
  • Choose the Dell S2721QS if you want a straightforward 4K IPS monitor for a desktop or console, with FreeSync for smoother games and dual HDMI inputs.

What reviewers say

LG UltraFine 27-Inch 4K UHD IPS Monitor

  • 4.6 / 526 ratings

Owners rate it highly, with 4.6 out of 5 from 26 ratings. They praise the sharp 4K image, color accuracy and the convenience of USB-C charging a laptop. Complaints center on HDR being modest and the panel not being built for fast gaming.

What people mention
  • Picture qualityPraisedOwners say the 4K panel is sharp and colors look accurate for editing and everyday use.
  • USB-CPraisedReviewers like charging a laptop and sending video over one cable.
  • HDRMixedDisplayHDR 400 is seen as a small step up rather than true HDR impact.
  • GamingCriticisedThe 5 ms response time and standard refresh rate are called limiting for fast games.

Dell S2721QS 27" 4K Monitor

  • 5 / 554,106 ratings

With over 54,000 ratings averaging near the top of the scale, owners are largely very satisfied. They praise the sharp 4K image, accurate colors and clean design. The main complaints center on the 60Hz refresh rate and modest HDR performance.

What people mention
  • Picture sharpnessPraisedOwners say 4K resolution makes text and photos noticeably crisp on the 27-inch screen.
  • Color accuracyPraisedReviewers report colors look accurate and consistent, which suits photo and video work in sRGB.
  • Refresh rateCriticisedGamers note the 60Hz panel is not suited to fast competitive play.
  • HDRMixed

Questions and answers

Which is better for photo and video editing?
The LG. Its 10-bit panel and up to 95% DCI-P3 coverage show more of the wide gamut that edited footage and raw photos use. The Dell's 99% sRGB is fine for web and office work but narrower.
Which is better for gaming?
The Dell, but only slightly. It has AMD FreeSync and a 4 ms response time; the LG has neither. Both are 60Hz 4K panels, so neither is a high-refresh gaming screen.
Can I use either with a laptop over one cable?
Only the LG. Its USB-C port carries video, data and up to 90W of charging, so a compatible laptop needs no dock or power brick. The Dell has no USB-C, so you need HDMI or DisplayPort plus separate charging.
Which lasts longer?
Neither has a clear edge in build. Both are IPS panels from major brands with standard warranties. The LG's stand adds a height and pivot mechanism, which is one more moving part; the Dell's simpler tilt stand has less to wear.
Is the LG worth stepping up to over the Dell?
Yes if you use a laptop or do color-critical work, because USB-C charging, the wider gamut and the adjustable stand are things the Dell cannot do. If you just want a 4K screen for a desktop, the Dell covers it.
Do both have speakers?
Yes. The LG has built-in stereo speakers with Waves MaxxAudio; the Dell has dual 3W speakers. Both are fine for calls and casual video, not for serious listening.
