I’ve already mentioned the 34M2C7600’s lack of RGB sliders. Luckily, three of the color temp presets are close to the mark. There is a little upward potential, but by and large, this is an accurate monitor.
Grayscale and Gamma Tracking
Our grayscale and gamma tests use Calman calibration software from Portrait Displays. We describe our grayscale and gamma tests in detail here.
The RGB level chart shows only slight errors at 70% brightness and higher. Since it’s my business to nitpick monitors, I would like to adjust this issue away, but I can’t. However, for most users, there is no visual problem. The grayscale looks neutral, with only a slight warmth. Gamma is a tad light, but it is close enough to the mark for most users’ satisfaction.
Raising the setting to 2.4 improves the gamma and raises the blue levels a tad. Visually, the difference is tiny. It may seem that I’ve taken a step backward with a higher grayscale error, but in practice, anyone, including myself, would be hard-pressed to see a color shift in a side-by-side comparison of actual content. The better gamma is worth a slight compromise in grayscale accuracy.
Comparisons
The 34M2C7600 starts in third place before calibration but slips to last after adjustment, thanks to the lack of RGB controls. This is unusual for Philips; I’ve always found adjustments in their other displays that delivered an improvement. But in the end, I was satisfied with the image. High color saturation and deep contrast more than account for a slight weakness in grayscale accuracy. Gamma performance is very good, with a slight advantage in image quality when the preset is on 2.4. So it compares well with the competition in that test.
Color Gamut Accuracy
Our color gamut and volume testing use Portrait Displays’ Calman software. For details on our color gamut testing and volume calculations, click here.
Color is an area where I have no complaints about the 34M2C7600’s performance. It covers a huge gamut with bonus red and almost the entire green primary, which is a rarity among wide gamut displays. Accuracy is high, with an average error of just 2.50dE. Calibration changes that to 2.66dE, which is an invisible difference. But I could just see the slight increase in red saturation, definitely a good thing.
As stated earlier, though the OSD has an sRGB option, it doesn’t render that gamut. You’ll be viewing the 34M2C7600’s full native color space for all content, SDR and HDR.
Comparisons
The 34M2C7600’s color accuracy is comparable to the other monitors. There is no visual difference in color accuracy, but you will notice the Philips’ extra color when compared to the AOC, BenQ and ASRock screens. Kudos to Monoprice for delivering high saturation without a premium backlight, but there’s no denying the advantage of the Mini LEDs in the Philips and ViewSonic panels. There is color aplenty here.
