Measuring HDR Brightness: Why Window Size Matters
A monitor's peak brightness depends on how much of the screen is lit. Here is how we measure it and which number to trust.

Demo data. This article describes HannahRev's draft methodology using fictional demo products. Any figures are illustrative — they are not laboratory results.
Most displays limit their total power, so a small highlight can be driven much harder than a full white screen. A single peak brightness figure therefore says little on its own; it matters how large the bright area was.
Window sizes
We measure white windows covering 2%, 10%, 25%, 50% and 100% of the screen, in the brightest calibrated HDR mode, after a warm-up period. Each review shows these as a bar chart in the HDR Brightness section.
Real-scene peak
The number we score is the real-scene peak: the highlight brightness while playing a fixed, representative HDR clip. It is the best predictor of what you will see in games and films.
| Rank | Product | HDR brightness (real scene) | Score |
|---|---|---|---|
| 1 | Norvik NX32-U160 | 950 cd/m² | 9.4 |
| 2 | Solenne Vista 34C | 820 cd/m² | 7.8 |
| 3 | Vireon V32-W240 | 520 cd/m² | 4.0 |
| 4 | Norvik NX27-Q240 | 455 cd/m² | 3.2 |
| 5 | Vireon V27-Q360 | 440 cd/m² | 3.0 |
| 6 | Altairon A27U Pro | 420 cd/m² | 2.8 |
| 7 | Kestrova K27F-180 | 335 cd/m² | 1.7 |
| 8 | Kestrova K24F-165 | 305 cd/m² | 1.3 |
