The 27" 4K productivity monitor is the most popular segment in the premium monitor market, and these two are perennial top picks. The Dell U2723QE uses IPS Black for better contrast; the LG 27UP850N is a more affordable but still excellent panel with great color accuracy. Both have USB-C with laptop charging.

Our Pick

Dell UltraSharp U2723QE

The Dell U2723QE wins for color-critical work and better contrast. For everyday productivity at a $100–$150 lower price, the LG 27UP850N is an excellent, slightly less featured alternative.

IPS Black Panel

The Dell U2723QE's IPS Black panel achieves a 2000:1 contrast ratio. RTINGS measured it at about 1700:1 in their testing — still nearly double standard IPS. For anyone working with photography, video, or design, the improved shadow detail is visible.

The LG 27UP850N uses standard IPS with about 1000:1 contrast. It's a high-quality panel — excellent color accuracy at 99% sRGB — but the contrast difference vs IPS Black is measurable.

USB-C and Connectivity

The Dell U2723QE has Thunderbolt 4 (90W charging), HDMI 2.0, DisplayPort 1.4, and a USB hub. The LG 27UP850N has USB-C (96W charging), HDMI 2.0 (×2), and DisplayPort 1.4. The LG actually charges at a higher wattage through USB-C, though it's not Thunderbolt.

Both work as single-cable MacBook docking stations. The Dell's Thunderbolt 4 also supports connecting another Thunderbolt display via daisy chain.

Color Accuracy

Both monitors are factory calibrated and rated for 99%+ sRGB coverage. The Dell U2723QE targets Delta E < 2 from the factory — suitable for photo editing and design work. The LG 27UP850N also ships with decent factory calibration, around Delta E 2–3.

For professional photo work, the Dell's factory calibration gives it a slight edge. For everyday productivity, both monitors look accurate and color-rich out of the box.

Ergonomics and Stand

The Dell U2723QE's stand offers height adjustment, tilt, swivel, and pivot for portrait mode — a well-rounded ergonomic package. The LG 27UP850N also includes height and tilt adjustment. Both include VESA mount holes.

Dell's monitor build quality is consistently praised in long-term user reviews. LG's is also solid, though some users report slight wobble in the base. Neither is a concern in typical desk use.

FAQ

Does the LG 27UP850N support macOS natively?

Yes. It works over USB-C with automatic resolution and the MacBook charges at 96W. Thunderbolt features (Target Display Mode, daisy chain) are unavailable.

Is IPS Black good for gaming?

At 60 Hz, neither monitor is a gaming display. IPS Black's improved contrast does help game visuals, but you'd want a high-refresh-rate panel for actual gaming.
