Demo rubric. Each scored metric is mapped linearly onto 0–10 between a 'worst' and a 'best' anchor and clamped. A test group score is the weighted mean of its metric scores. A usage score is the weighted mean of its group scores; groups marked not applicable are dropped and the remaining weights are re-normalised. The overall score is the mean of the four usage scores. Anchors and weights are placeholders until HannahRev publishes its production methodology.
A versatile high-end gaming monitor. It pairs 4k sharpness with OLED motion clarity, and the 480Hz mode is a real bonus for esports. Its RWBG subpixel layout makes text a little softer than on an RGB panel.
Key measurements against the alternatives we recommend considering.
The V32-W240 is the most versatile gaming monitor in the demo set.

Vireon V32-W240
Norvik NX27-Q240
Two OLED gaming monitors at different sizes: the NX27-Q240 is the better choice for bright colours at 1440p, the V32-W240 for a larger, sharper 4k image.
Vireon V32-W240
Altairon A27U Pro
Both are 4k. The V32-W240 wins for games and HDR; the A27U Pro is better for colour-critical editing and bright offices.
Vireon V32-W240
Norvik NX32-U160
Two 32-inch 4k monitors. The NX32-U160 is far brighter; the V32-W240 has perfect blacks and much faster motion.
