LG 27GM950B-B: Specs, Features, Pros & Cons
This review measures the LG 27GM950B-B against the full 41-spec sheet we track for monitors, comparing it like for like with the 69 other models in our database. It earns a VS Score of 59 out of 100 — the weighted result of every verified specification measured against the class average.
On the spec sheet it is strongest in connectivity and weakest in gaming. Its clearest single advantage over the class average: 85.21 ppi more pixel density — 218 ppi vs 132.79 ppi (avg). None of our retail partners currently lists the LG 27GM950B-B, so availability may be limited; a missing price never affects the VS Score. A transparency note: this spec sheet is 71% complete. Anything unverified shows as Unknown and is left out of the score — we never estimate a missing value.

Editor’s note
The 27GM950B is the rarest specification in this catalogue: 5K on a 27-inch panel, at 165 Hz.
That works out to 218 pixels per inch — the density Apple's Retina displays use, and roughly double the 109 ppi of a 27-inch 1440p monitor. Text renders without any visible pixel structure at desk distance, which is the single biggest quality-of-life difference for anyone who reads or writes for a living. Nearly every other 5K monitor stops at 60 Hz, so pairing that density with 165 Hz and G-Sync Compatible variable refresh is genuinely unusual.
It is not an OLED, and here that is a deliberate advantage. The mini-LED backlight has local dimming and reaches 1,000 nits with DisplayHDR 1000 certification, so HDR has real impact — while a static taskbar can sit on screen for years without any retention risk. Colour coverage is 98% DCI-P3 at 10-bit.
Connectivity covers USB-C, a USB hub, two HDMI 2.1 ports and DisplayPort 1.4, and the stand adjusts in every axis including pivot.
Two practical points. Driving 5K at 165 Hz needs a serious graphics card and modern cable; at lower frame rates the density still pays off for work. And the 1 ms response is fast for IPS but not the 0.03 ms an OLED delivers, so competitive players will see a difference in motion clarity.
Buy it if you work with text all day and game in the evening, and want one monitor that is excellent at both. Buy an OLED if motion clarity outranks sharpness.

How the VS Score works — and what it can’t tell you
Every measurable spec is scored against the average of all the monitors we track: matching the class average scores 50, clearly beating it climbs towards 100, and each spec counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The quality bars on the spec cards above show where this model sits inside the full range for its class, and the overall VS Score rolls every weighted result into one number.
Unknown values are never estimated. A spec this product doesn’t report simply drops out of its scoring — it isn’t penalised with a guess — but a thinner spec sheet does mean a score built on fewer data points, which is why completeness is disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the VS Score as a structured summary of what can be measured, not a substitute for your own priorities.
About this data
- Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
- Specifications last verified July 25, 2026.
- Data completeness: 29 of the 41 specs in this category are verified (71%). Anything we could not verify is shown as Unknown — never estimated — and is excluded from the score.
- Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
- Want the full picture? Our editorial guidelines explain how we research products, weight the scores and stay independent.

The bottom line
The LG 27GM950B-B earns a VS Score of 59, comfortably above average among the 70 monitors we compare here. It stands out for has local dimming, 85.21 ppi more pixel density and has USB-C. Just be aware of 51.37 Hz less refresh rate and 2.29" (5.81 cm) less screen size before you buy. For most buyers it is an easy recommendation.
The VS Score is generated automatically from the weighted specifications above, measured against all other monitors in our database. Treat it as a shortlisting guide — not a substitute for your own priorities.
