Philips Momentum 27M1N5500 Monitor Review: 170 Hz for flawless responsiveness


By default, this Philips monitor delivers excellent image quality. Color temperature and gamma curves are stable across the spectrum. The gamma measured at 2.2 is in agreement with the reference value, which results in perfectly reproduced gray levels, while the average color temperature measured at 6340 K is very close to the reference value of the standard video (6500K).

Also, the colors are perfect. As proof, the average delta E peaks at 2.6, i.e. less than 3, the threshold below which the eye no longer perceives colorimetric drifts. By lowering the brightness of the screen to 41 in order to obtain a white close to 150 cd/m², the image quality remains the same. This rendering is good enough not to have to calibrate the screen.

The screen obviously covers 100% of the standard sRGB color space and also rises to 95% of the DCI-P3, the color space used mainly by Ultra HD content (Movies and TV Series). This monitor is also HDR compatible, but the low contrast associated with a limited peak of brightness (319 cd/m²) clearly limits the interest of HDR.

We measured a contrast of only 675:1, a very low value for an IPS model. In comparison, the contrast of the best IPS monitors like theAsus VG27AQ exceeds 1200:1, when the vast majority already displays a native contrast of 1000:1. On screen, this low contrast results in washed-out blacks that appear greyish. This is not very serious for use in broad daylight, but it has an impact in the dark and in dark scenes which are then systematically overexposed.

The average difference in white homogeneity is 6% on the 27-inch panel, and it can even drop to 1% by activating the mode Smart Uniformity. There is thus no variation in brightness perceptible to the eye. We did not notice any light leaks around the corners or any clouding (“cloud effect”) on our test model. The IPS technology also offers very good viewing angles, with very little variation in the angles.
