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: $300.00 to $499.98 (±25% of this product’s price). Comparable evidence is limited.

Match evidence or required features still need confirmation.

Independent expert testing, exact-model owner signals and manufacturer specifications are visibly separated. Piqelo never counts itself as product evidence.

Exact-model findings and measurements

Trade-off · console fit

RTINGS’ exact 27GX704A-B verdict confirms downscaled 4K at 120Hz from PS5 and Xbox Series X|S through HDMI 2.1. It also reports connection issues when switching from PC to console; these are test observations, not a population failure rate.

Trade-off · bright room

The exact glossy 27GX704A-B test reports distracting reflections in sunny rooms, text fringing and visible VRR flicker with changing frame rates. Its public numeric test fields are locked; 0.0 placeholders are not actual scores.
