Samsung SyncMaster F2380
Next goes the 23-inch SyncMaster F2380 that features a Full-HD resolution of 1920x1080 pixels. Its specs go like that: a contrast ratio of 3000:1, a brightness of 300 nits, and a response time of 8 milliseconds (GtG).
By default, the monitor has 100% Brightness and 75% Contrast. I achieved a 100nit white by choosing 40% Brightness and 47% Contrast. The monitor regulates its brightness by means of backlight modulation at a frequency of 180Hz.
Color gradients are reproduced correctly, without banding.
Like the F2080, the F2380 differs by no more than 16 milliseconds from a Samsung SyncMaster 710N in terms of input lag. In other words, its input lag can be disregarded as negligible.
The maximum brightness is indeed higher than with the 20-inch model. The contrast ratio is higher, too. It is over 1800:1 at the default settings. At the reduced settings and in the dynamic contrast mode my calibrator found itself below the bottom measurement limit.
The MagicBright modes are set up properly, but the Text and Internet modes are rather too bright for home use. You may want to set the monitor up manually for text-based applications and use those modes for viewing photos, watching movies and playing games under dim evening lighting. There are no color distortions in the MagicBright modes.
The color gamut is not extended. It fully covers the standard sRGB color space in all the three basic colors.
The average nonuniformity of white brightness is 4.6% with a maximum deflection of 11.9%. For black, the average and maximum are 7.8% and 19.8%. The numbers are good for white but worse than average for black. On the other hand, the high overall contrast ratio of the monitor will conceal the nonuniformity of its backlight.
The gamma curves are nearly ideal at the default settings. They almost coincide with the theoretical curve.
When the monitor’s Contrast and Brightness settings are set below their defaults, there appears a hump in the gamma curves as we have already seen with the SyncMaster F2080. The hump is smaller here, though.
The color temperature setup is acceptable. It is only the darkest tones that have a bluish hue, but that’s not a big problem. If you don’t count the darkest tones in, the temperature dispersion between the different levels of gray is within 1000K.
I set the monitor up manually (Custom mode) at 50% Contrast and controlled the result with my calibrator. I finally selected the following values in the Color menu: Red=50, Green=37, Blue=40. I did not change the value of gamma in the monitor’s menu (it is set at Mode1 by default). My setup helps reduce the temperature dispersion to 1100K or, if the darkest tones are not counted in, to 800K.
Like with the F2080, there is excessive green in every predefined mode as the gray point diagrams above show. But I nearly got rid of the excess of green when I set the monitor up manually in Custom mode.
However, it is impossible to achieve an ideal result using the monitor’s own tools. You should calibrate it in order to get really accurate colors. You can do this with any hardware calibrator or manually with the CLTest program. The latter method calls for perseverance and neatness, but I do recommend you to try calibrating your monitor manually if you can’t use a hardware calibrator.
In the Normal mode of response time compensation – when RTC is virtually turned off – the response time average is 21.7 milliseconds (GtG) with a maximum of 75 milliseconds.
In the Faster mode, which is selected by default, the response time average is not much lower at 19.8 milliseconds (GtG). It is mostly gray-to-gray transitions that are affected.
The Fastest mode doesn’t change much, either. Its response time average is 18.7 milliseconds (GtG) with a maximum of 75 milliseconds. Alas, the F2380 is considerably slower than the F2080. The latter’s gray-to-gray transitions take about 10 milliseconds, but here they are as long as 15 to 20 milliseconds.
