LG 27GP850-B

Scored on 305 verified owner verdicts, from 3,057 comments read across 2 communities
TL;DR
The consensus among owners is that this is a standout budget-to-mid-range 1440p gaming monitor: praised repeatedly for its price-to-performance ratio, vivid Nano IPS colors, fast/smooth response times, and 165-180Hz refresh rate that makes older 60Hz or 1080p setups feel obsolete. Many owners report years of trouble-free daily use and call it one of the best monitors they've owned, especially when bought on sale. The recurring gripe, though, is contrast - owners across dozens of comments call the roughly 700-800:1 ratio disappointing even for an IPS panel, producing grayish blacks in dark scenes, and a meaningful minority also complain about the clunky stand/power-brick design, IPS glow/backlight bleed, and HDR that's more marketing than substance. A smaller but persistent group also reports quality-control issues on arrival, from stuck pixels to units that died early.

69% of 305 verified owners recommend the LG 27GP850-B, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

The headline score reflects owners (Reddit, enthusiast forums), independent lab tests, blogs with no affiliate links, and YouTube owner-comments when they line up with owners. YouTube is shown for perspective but kept out here — hover the i for why.

What owners like
  • Exceptional value for the price, especially found on sale in the $200-$350 range · 32 · 10%
  • Vivid, accurate colors from the Nano IPS panel that owners say beat rivals like Dell UltraSharp and standard IPS/BGR panels · 22 · 7%
  • Fast pixel response times and smooth motion with little to no ghosting, even compared to dedicated esports monitors like the Zowie XL2540/XL2546 · 16 · 5%
  • High 165-180Hz refresh rate (with easy overclock to 180Hz) makes a huge, immediately noticeable jump from 60/144Hz setups · 12 · 4%
  • Long-term reliability, with many owners reporting 2-4+ years of daily/24-7 use with zero issues · 11 · 4%
What owners flag
  • Weak contrast ratio (frequently cited around 700-800:1), leaving blacks looking gray, especially in dark rooms and night scenes · 24 · 8%
  • Awkward stand and power design: a bulky non-standard power brick, limited/no swivel, and a minimum height that many find too high · 16 · 5%
  • Quality-control inconsistency on arrival, including stuck/dead pixels, backlight bleed, and a few DOA or early-failure units · 13 · 4%
  • Noticeable IPS glow and backlight bleed in corners, worse when viewed off-angle · 9 · 3%
  • HDR support is weak in practice (HDR 400, no local dimming), often described as washed-out or effectively fake HDR · 7 · 2%
Who it's for
A great fit if
  • Competitive gamers wanting fast 1440p 165-180Hz response times on a budget
  • Buyers who can snag it on sale (~$200-300) for strong price-to-performance value
  • Mixed gaming-and-work users fine with an IPS panel's accurate colors and wide viewing angles
  • Console gamers (PS5/Switch) wanting solid upscaling and smooth motion clarity
Look elsewhere if
  • Anyone doing dark-room movie watching or color-critical work, since contrast and blacks are widely called poor
  • HDR enthusiasts, as owners repeatedly say HDR performance is weak to unusable
  • Buyers wanting the newest tech, since many now call it an aging 2021 panel outclassed by newer/cheaper monitors

Redditⓘ good to know

“It has the best color accuracy at 96% DCI-P3 > LG Ultragear 27 inch 27GP850-B This has LG Nano IPS technology. It's not as good as Quantum Dot, but it's an intermediate.”

Redditⓘ good to know

“Yes it’s rated at HDR10. But the 27inch variant of the same monitor (27GP850) is rated at HDR400. There were a few reviews where I saw the 32 inch variant pushing to HDR400.”

Redditⓘ good to know

“They could've put HDMI 2.1 in it but they didn't. If they did I'm pretty sure we would get VRR 1440p @120hz. Luckily for me I primarily use it with my gaming pc though.”

Redditⓘ good to know

“Looks like the LG 27GR75Q has a lower max refresh rate, 165Hz vs 180Hz. Also less glare reduction. https://www.rtings.com/monitor/tools/compare/lg-27gp850-b-27gp83b-b-vs-lg-27gr75q-b/24452/44761”

Redditⓘ good to know

“I changed Adaptive-Sync/VRR/G-sync from "Extended" to "Basic" in monitor settings and it fixed the issue. Also I have lowered contrast in monitor menu and nVidia control panel. My monitor is LG 27gp850-b”

Redditⓘ good to know

“I managed to get it to appear when I enabled the overclock to 180Hz on the monitor OSD, and I was able to change resolutions in Windows and a couple of games, but after booting up now, the setting seems to have disappeared again.”

Redditⓘ good to know

“I have the 27GP850, it also acts like a USB Hub. I think the model in your list is the same, but doesn't function like a USB Hub”
