LG 27GP850-B vs Dell UltraSharp U2723D: Gaming Monitor vs Office Monitor

Same desk, two very different jobs. That's the real question behind this comparison.

The LG 27GP850-B is a 27-inch 1440p IPS panel at 165Hz for $349.99, built for people who game after they clock out.

The Dell UltraSharp U2723D trades refresh rate for resolution and contrast: 4K, IPS Black at 2000:1, factory calibrated, for $549.99.

Neither wins outright. If you ever game at your desk, even occasionally, the LG's 165Hz makes the Dell's 60Hz feel sluggish by comparison. If the monitor is strictly for work, the Dell's contrast and calibration are worth the extra $200.

One Question Decides This

Do you ever game at your desk?

If yes, even occasionally: LG 27GP850-B. The Dell's 60Hz makes gaming on it perceptibly worse than any 144Hz+ monitor.

If no: Dell U2723D. The IPS Black contrast, 4K resolution, factory calibration, USB hub, and pivot stand are all relevant for office work and none of them help gaming.

The 60Hz vs 165Hz Difference in Practice

60Hz means 60 frames displayed per second. 165Hz means 165 frames. For document work, spreadsheets, and video calls: 60Hz is indistinguishable from 165Hz. Scrolling through documents is smooth; cursor movement is responsive.

For gaming: 60Hz is a hard ceiling. Games rendered above 60fps are displayed at 60fps, producing micro-stuttering when the frame rate fluctuates below 60. Input lag is perceptibly higher — one frame at 60Hz is 16.7ms; at 165Hz, it is 6ms.

If you have ever used a 144Hz+ monitor for gaming and then switched to 60Hz, the difference is immediately visible. It is not subtle.

The 1000:1 vs 2000:1 Contrast Difference

Standard IPS panels, including the LG 27GP850-B, have approximately 1000:1 contrast ratio. The Dell U2723D's IPS Black achieves 2000:1.

In practice on productivity work: dark text editor backgrounds (like VS Code with a dark theme) appear darker and more saturated on the Dell. White text on the near-black background is more legible — the background is darker, the text appears to have higher contrast.

On light-themed interfaces, the difference is less visible — both panels produce similarly white backgrounds.

For gaming: 2000:1 improves dark scene rendering. In a forest level at night or a game with heavy shadow use, the Dell's deeper blacks produce more shadow detail. For competitive gaming on bright-background maps, the difference is less relevant.

USB Hub Difference

The LG has USB-C with 90W power delivery and video signal. That is the extent of its connectivity.

The Dell has USB-C with 90W power delivery, video signal, plus 3x USB-A ports and Ethernet. This means a laptop connected to the Dell's single USB-C cable has access to keyboard, mouse, USB storage, and wired internet — all through the monitor.

For a clean desk setup with a laptop as the primary computer, the Dell eliminates a separate USB hub and a separate Ethernet adapter. The LG requires both separately to achieve equivalent connectivity.

1440p vs 4K for Office Work

At 27 inches, 1440p at 100% scaling produces readable text. 4K at 27 inches at 100% scaling produces very small text — most people use 125% scaling, which produces text equivalent to approximately 1440p in size but sharper due to the higher pixel count.

For document work where reading long-form text is the primary activity: 4K is marginally better at sharp text rendering, more noticeably better for fine detail in graphs and presentations.

For coding: 4K at 125% scaling shows more code lines at equivalent readability compared to 1440p.

The difference is real but subtle. If you do not work with high-density visual content, 1440p at 27 inches is fine.

The $200 Price Gap

Dell U2723D: $549. LG 27GP850-B: $349. A $200 gap.

The Dell's premium buys:

• IPS Black panel (2000:1 vs 1000:1)
• 4K vs 1440p
• Full USB hub (USB-A + Ethernet) vs USB-C only
• Portrait pivot
• Factory calibration
• 3-year Advanced Exchange warranty

If you need all of these, the Dell is worth the premium. If gaming is part of your use case, none of these features matter as much as the refresh rate you are giving up.
