SyncMaster XL2370 Performance
The monitor has 100% brightness and 75% contrast by default. I achieved a 100nit white by dropping the brightness and contrast settings to 38% and 40%, respectively. The monitor regulates its brightness by means of pulse-width modulation of the power of the backlight lamps at a frequency of 180Hz.
The SyncMaster XL2370 was not available in retail at the time of my tests, so I tested a sample Samsung Electronics had been kind to provide to me.
There are no differences from the P series in terms of response time so far. The Normal mode means there is no RTC. The monitor is as slow as 15.2 milliseconds (GtG) here.
In the Faster mode transitions from black and white to gray remain slow but gray-to-gray transitions are greatly accelerated, resulting in a response time average of 5.5 milliseconds (GtG).
The RTC error average is a mere 4.4%, which is very low. RTC-related artifacts won’t be conspicuous in games or at work.
The pixel relaxation time after an RTC miss is 8.7 milliseconds on average. That’s a good result, too.
The picture shows that the Fastest mode is almost no different from Faster. The numbers agree: the response time average is 5.0 milliseconds (GtG).
The RTC error average increases to 8.0% but the resulting visual artifacts won’t be conspicuous.
The pixel relaxation time grows to 13.3 milliseconds, which is not too bad, either.
Thus, the SyncMaster XL2370 is the only monitor I have tested for this review that has an acceptable level of visual artifacts in the Fastest mode. On the other hand, the response time does not improve much in that mode, either. So, I guess the Faster mode is still the optimal compromise between speed and visual artifacts.
By the way, judging by the names of the modes and the response time results, the XL2370 is closer to the 50 series monitors than to the 70 series. Well, this may be due to the fact that I tested a presale sample of the monitor. Its firmware may be corrected later as this is a simple operation.
I did not spot any input lag on the SyncMaster XL2370 in comparison with a Samsung SyncMaster 710N which has zero input lag.
Brightness and Contrast
The XL2370 is roughly equal to the 50 series monitors in terms of maximum brightness and contrast ratio, stopping short of the 300nit mark.
Alas, the XL2370 does not excel in this test. For all its LEDs, the extremely slim case must have affected the uniformity of backlight: the screen gets considerably brighter in the bottom part. The average nonuniformity of white brightness is 7.9% with a maximum deflection of 19.5%. For black brightness, the average and maximum are 8.3% and 22.2%, respectively.
The monitor’s color gamut coincides with sRGB much better than the color gamut of monitors with fluorescent backlight lamps. Take note that it coincides but does not exceed sRGB. There is no talking about an extended color gamut here.
The gamma curves for red and green look good. The blue curve is sagging.
The XL2370 delivers a high accuracy of white balance. It is better than the other monitors discussed in this review in this respect. The pictures indicate no significant deflection to greens or blues.
The numbers agree: the difference between the temperatures of different grays is within 300K in the Normal mode. The average value is but slightly higher than 6500K, which is considered standard for sRGB monitors. It’s just an excellent result!
The Text mode is somewhat too bright, so you may want to set the monitor up manually for working with text at home. Otherwise, I have no questions regarding MagicBright technology. The preset modes have different levels of brightness and do not distort color reproduction. And most importantly, they can be instantly switched by pressing a single button.
