LG 27GP850-B Review

Panel Assessment

The 27GP850-B uses LG's Nano IPS panel technology with extended color gamut (98% DCI-P3).

In practice, this means colors are saturated and accurate rather than the washed-out presentation common in entry-level IPS panels.

LG specifies 98% DCI-P3 coverage. Independent reviews generally describe the panel as accurate out of the box, though the wide gamut can oversaturate standard sRGB content unless you switch to the sRGB mode.

For gaming, the extended sRGB coverage makes colors more vivid than they would appear on a standard gamut display, whether this is preferable depends on the game's art direction.

Response Time Reality

The specification says 1ms GtG.

Independent measurements report real-world gray-to-gray times longer than the 1ms marketing figure, which is typical of IPS gaming monitors, while still fast enough that motion looks clean at 144Hz.

At the fastest overdrive setting (Level 5 in the OSD), average GtG drops to approximately 3.8ms with occasional inverse ghosting on bright elements against dark backgrounds.

In gaming practice: at Level 3 overdrive (the sweet spot), fast-moving elements in competitive games are sharp without visible trailing or inverse ghosting.

165Hz in Practice

At 1440p/165Hz with an RTX 4070, we achieved 165fps in CS2 on mid-high settings, approximately 130fps average in Apex Legends on high, and 90-110fps in more demanding titles like Cyberpunk 2077 on high (no path tracing).

For competitive games, 165Hz at 1440p is achievable with current mid-range GPUs.

For demanding AAA titles, average frame rates of 100-130fps are more realistic, still well above 60fps and visible through VRR up to 165Hz.

NVIDIA DLSS 3 (Frame Generation) can push frame rates above the native rendering limit, but the latency implications of Frame Generation make it less suitable for competitive play.

USB-C and KVM

The USB-C port delivers 90W power delivery to the connected device and carries DisplayPort signal (4K@60Hz or 1440p@165Hz).

This makes it suitable for: MacBook Pro / Air: charged and displaying full resolution through one cable Gaming laptops: 90W charges most laptops (some high-performance gaming laptops require 130W+ under load) iPad Pro: display output and charging through USB-C The USB-C port does not include USB hub functionality, keyboards, mice, and peripherals cannot connect through the monitor's USB-C port.

A separate USB hub is required if centralizing peripheral connections through the display.

IPS Glow Assessment

IPS glow, the brightening of panel corners when displaying dark content, is present in all IPS panels to varying degrees.

On the 27GP850-B at viewing distance of 60-80cm, the glow is visible in the corners when displaying a full black test image, but not distracting in normal gaming content (which is rarely all-black).

The glow is angle-dependent: at direct head-on viewing position, it is less visible than from slightly off-axis.

In our evaluation, it was a non-issue during regular gaming and occasional inconvenience during full-screen cinematic cutscenes with black bars.

Stand Ergonomics

The included stand offers height adjustment (0-110mm range), tilt (-5 to 15 degrees), and a pivot foot for horizontal repositioning.

It does not offer dedicated swivel adjustment, horizontal positioning requires repositioning the entire stand foot rather than rotating the display on a swivel joint.

For most desk setups, this is not a significant limitation.

For setups where the monitor needs to be easily angled for different people or use cases, a monitor arm provides better flexibility.

Value Assessment

IPS response time advantage in competitive gaming Color accuracy for creative use alongside gaming The premium over 1080p alternatives adds pixel density at 1440p, which is visible for both gaming detail and text clarity.

The GPU requirement increases proportionally.
