SyncMaster P2370 Performance
The monitor has 100% brightness and 75% contrast by default. I achieved a 100nit white by selecting 50% brightness and 54% contrast. The monitor regulates its brightness by means of pulse-width modulation of the power of the backlight lamps at a frequency of 180Hz.
The Normal mode is again slow, the overall average being 14.5 milliseconds (GtG).
It is better in the Still mode: four transitions from black to dark gray remain slow while the response time average improves to 4.1 milliseconds (GtG).
The RTC error average is 8.8%, which is acceptable.
Alas, the average pixel relaxation time is rather high at 16.6 milliseconds which equals the duration of a single frame. This affects the visibility of RTC artifacts. I wouldn’t say that they are too distracting, though.
There is only one transition from black to dark gray that remains slow in the Movie mode, which is the fastest. The resulting response time average is 2.5 milliseconds (GtG).
Unfortunately, this comes at a traditionally high price: the RTC error average is 21.4%.
The average pixel relaxation time is as high as 26.2 milliseconds. The resulting visual artifacts are perfectly visible when you are moving application windows or making fast movements in games. So, notwithstanding the fast response in the Movie mode, it is better to set the P2370’s responsiveness at Still.
I did not spot any input lag on the SyncMaster P2370 in comparison with a Samsung SyncMaster 710N which has zero input lag.
Brightness and Contrast
The monitor’s brightness complies with its specs. The contrast ratio is good, even though lower than specified.
The uniformity of backlight is the weak point that all the 70 series models share. It must be due to the difficulty of ensuring uniform fastening of the LCD panel in their slim cases as opposed to the more massive cases of the 50 series.
With the SyncMaster P2370, the average nonuniformity of white brightness is 6.3% with a maximum deflection of 18.7%. For black brightness, the average and maximum are 6.7% and 31.0%, respectively. Besides, the eye can see weak vertical dark waves that cannot be recorded due to the sensor’s low spatial resolution.
The monitor’s color gamut is almost the same the standard sRGB color space.
At the default settings the blue curve differs from the others, sagging below the theoretical one. The curves for green and red are close to the ideal curve for gamma 2.2.
When the contrast ratio is reduced, the curves improve and get close to each other. They are shaped somewhat differently than the theoretical curve, but that’s not a big problem.
The SyncMaster P2370 shows the common drawback of all these new monitors from Samsung. It has an excessive green. This can be amended by manually adjusting the color temperature. In this case, I just selected the following values in the monitor’s menu: R=50, G=35 and B=50.
The color temperature dispersion between the different grays is very small.
The MagicBright modes are set up in the usual way: you should set the monitor up manually for working with text and browsing the Web, while the MagicBright modes are suitable for viewing photos, watching movies and playing games.
