LG UltraGear 27GR83Q-B: Specs, Features, Pros & Cons
This review measures the LG UltraGear 27GR83Q-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 37 out of 100 — the weighted result of every verified specification measured against the class average.
On the spec sheet it is strongest in gaming and weakest in features. Its clearest single advantage over the class average: 23.63 Hz more refresh rate — 240 Hz vs 216.37 Hz (avg). None of our retail partners currently lists the LG UltraGear 27GR83Q-B, so availability may be limited; a missing price never affects the VS Score. A transparency note: this spec sheet is 85% complete. Anything unverified shows as Unknown and is left out of the score — we never estimate a missing value.

Editor’s note
The 27GR83Q-B is a well-balanced 27-inch QHD gaming monitor for people who want speed without OLED ownership concerns. A 240 Hz IPS panel provides smooth motion, wide viewing angles, and sharp enough pixel density for both work and play. It is easier to drive than 4K at the same frame rate, making it a sensible match for competitive games and upper-midrange graphics cards.
Response time is advertised at 1 ms in the fastest setting, but aggressive overdrive can introduce inverse ghosting. Use the mode that looks clean at your chosen refresh rate rather than automatically selecting the maximum. DisplayHDR 400 and roughly 400-nit peak brightness provide basic HDR compatibility, not the deep contrast or highlight intensity of Mini-LED or OLED. The 1,000:1-class IPS contrast means dark-room blacks appear gray.
Connectivity is strong for mixed PC and console use: two HDMI 2.1 inputs, one DisplayPort 1.4 input, a USB hub, and headphone output. FreeSync Premium and G-Sync compatibility handle variable refresh. The stand supports height, tilt, and pivot but not swivel. There are no built-in speakers, USB-C power delivery, KVM, webcam, microphone, or Ethernet, so a laptop-centered setup will need extra peripherals.
This LG suits esports players, general gaming, and everyday productivity where 240 Hz and QHD are a practical sweet spot. It is not the best choice for dark-room cinema, serious HDR, or one-cable laptop docking. Compare GPU capability before paying extra for 240 Hz, and verify the model number is 27GR83Q-B; other 27-inch UltraGear displays can look nearly identical while using slower panels or older HDMI bandwidth.

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 August 3, 2026.
- Data completeness: 35 of the 41 specs in this category are verified (85%). 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.
