Display Measurements
Before we get into testing battery life, we need to calibrate the P34W v3’s display. In the process of doing this, we also run its panel through a barrage of benchmarks.
| Minimum Brightness | 9.03 cd/m² |
|---|---|
| Maximum Brightness | 289.23 cd/m² |
| Brightness Calibration | 201.13 cd/m² (69 on brightness scale) |
| Black Level | 0.34 cd/m² |
| Gamma | 2.18 |
| Contrast Ratio | 582:1 |
| Color Temperature | 6460K |
| sRGB Gamut | 101.7% |
| Adobe RGB Gamut | 70.1% |
A minimum brightness measurement of 9.03 cd/m² is well below our practical floor of 50. AU Optronics rates its B140HAN for a maximum brightness of 300 cd/m² and the panel on Gigabyte’s P34W v3 comes awful close to that figure at 289.23.
By default, an ambient light sensor adjusts the P34W’s screen and backlight. This needs to be disabled in order to get the display calibrated for our testing. Different publications favor certain outputs, but all of our screens are dialed to 200 cd/m².
At that setting, we measure a contrast ratio of 582:1, which registers lower than the display’s typical 700:1 rating. A gamma response of 2.18 comes close to the 2.2 we want to see. We record a cool color temperature of 6460K, and a sRGB gamut volume of 101.7%.
Subjectively, the P34W v3’s display is excellent, though not particularly vibrant owing to its anti-glare layer. Uniformity isn’t an issue; there is no perceptible light bleed to the naked eye. And the panel’s viewing angles are superb. You don’t experience any color shift. Even if Gigabyte wasn’t using an IPS-equivalent panel, the relatively small 14” screen keeps you head-on most of the time. But the fact that you get AUO’s AHVA technology means all practical viewing angles are usable.
