How these scores work

The Piqelo Score is our published assessment of this exact product, including value. Your search does not change it. The Search Score uses the underlying research, your preferences and comparison with similarly priced products. Value is counted once; budget and required features are hard limits.

Price comparison: $600.00 to $999.98 (±25% of this product’s price). Comparable evidence is limited.

Match evidence or required features still need confirmation.

Exact-model findings and measurements

Trade-off · connectivity docking

PCWorld’s exact 27GM950B-B review found the bright Mini LED display and matte anti-glare finish useful for mixed work and gaming, but noted weak speakers and no KVM. Listed 750/1250-nit specifications are not independently measured luminance.

The review’s specification table contains inconsistent resolution wording; no numeric resolution or brightness measurement is inferred from it.

Supported finding · connectivity docking

PCWorld notes weak speakers and no KVM on the exact LG UltraGear 27GM950B-B.

Trade-off · sdr image

PCWorld observed that small bright details, including a white cursor on a black background, could become too dim with local dimming. Adjusting or disabling dimming helped desktop work. This is a reported usage observation rather than a quantified luminance measurement.

Trade-off · connectivity docking

The 27GM950B-B review confirms USB-C DisplayPort Alt Mode and a two-port USB-A hub. With only one USB upstream input, there is no KVM function for sharing peripherals between two computers.
