Quick verdict
The 27GM950B-B is the first 5K Mini LED gaming monitor TFTCentral has tested: 5120×2880 at 27 inches (about 218 pixels per inch) with 2,304 dimming zones, a 1440p 330Hz mode, DisplayPort 2.1, USB-C with power delivery, and KVM. It is the IPS choice for people who read, code, or edit for hours and want serious HDR for games without OLED care.
We rank it below simpler picks because the measurements we could attribute are limited: TFTCentral's review presents most results in video form, and it disclosed that LG sponsored the review while retaining editorial control. Treat our assessment as specification-led until more independent data is available. Driving 5K also demands a powerful GPU.

What independent testing reports
We did not find numeric measurements for this exact model that we could attribute with their test conditions. Statements below are either manufacturer specifications or reviewers' qualitative findings, and each one says which.
Motion, response, and latency
The 1440p 330Hz mode gives about 3.0 ms frame duration on a sample-and-hold display versus about 6.1 ms at 165Hz. We did not find attributable response or lag figures.
Image quality and HDR
The listing states DisplayHDR 1000, and TFTCentral confirms 2,304 dimming zones. More zones generally reduce blooming, but we have not found attributable blooming or brightness measurements. Specification-based only.

Questions buyers ask
Why 5K on a 27-inch monitor?
At about 218 pixels per inch, text looks print-sharp with 200% scaling, similar to Apple's 5K displays. For games, the 1440p 330Hz mode is easier to drive.
Final recommendation
A compelling premium IPS for text-heavy users who also game, with the caveat that independent data is still limited.
