The 20-inch T200 has the same specs as the T190, the size of the screen being the only difference.
The T200 has 100% brightness and 75% contrast by default. I achieved a 100nit white by selecting 40% brightness and 42% contrast. The monitor regulates its brightness by means of backlight modulation at a frequency of 323Hz.
Light halftones are indistinguishable from white at a level of Contrast higher than 88%.
The color gamut of the T200 covers the standard sRGB color space and is even larger than it in green and turquoise hues. However, the T200 is not counted among extended-gamut models.
The average nonuniformity of white brightness is 6.7% with a maximum of 15.5%. The average and maximum nonuniformity of black brightness are 5.5% and 21.3% respectively. The pictures show that the sides of the screen are darker than the rest of it.
The gamma curves are quite acceptable at the default settings. They do not betray any serious defects.
The shape of the curves does not change much when the contrast setting is reduced in the monitor’s menu, but all the three curves get somewhat higher. Both light and dark halftones are reproduced without problems.
The color temperature setup is a disappointment. There is a temperature dispersion of over 2000K in the Normal mode! As a result, although white looks like white, gray has a noticeable blue tint.
The table shows that the darker the gray is, the more its temperature differs from white. If the deflection were the same, you could just lower the contrast setting and use the monitor’s options to set the desired level of color temperature. You can’t do that with the SyncMaster T200, at least with the sample I dealt with. Anyway, I tried to set the monitor up – not calibrate it with a hardware calibrator but set it up using the options available in its onscreen menu. Reducing the contrast option to 50% and setting the color temperature sliders as R=51, G=42 and B=46, I achieved the desired 6500K as the color temperature of white, but gray was still bluish. You can read the numbers in the Custom column of the table above.
However, setting the T200 up manually makes sense: the pictures above show that that the monitor has a slight greenish hue in every preset mode. Although I did not correct the difference in the temperature of white and gray, I did get rid of the excess of green.
The maximum brightness of the T200 is lower than specified, but that’s not a problem. 250 nits should be enough for any application, even for watching movies and games under bright daylight. The Custom column shows the parameters achieved after the manual setting up of the monitor as described above. Of course, you can additionally lower the brightness of the screen with the appropriate setting to a level that is comfortable to you.
Like every other monitor from Samsung, the SyncMaster T200 offers several preset modes differing in brightness. You can choose a mode by pressing the Down button without entering the main menu. The table shows that each mode has adequate brightness for the intended application (except that the Internet mode is meant for viewing images rather than for reading text of web pages).
The last column in the table corresponds to dynamic contrast mode. It was filled in in two steps. The level of black was measured on a black screen. The level of white was measured on a white screen. The value of 0.02 nits for the level of black is the measurement accuracy of my Datacolor Spyder3 Elite calibrator. In fact, the real level of black might be lower than 0.02 nits but my calibrator could not measure it. In other words, the monitor has a contrast ratio of no less than 13,000:1.
The Text is the darkest of the modes and suits well for working in text-based applications under good office lighting. The gamma curves are the same as at the monitor’s default settings. There are no serious color distortions.
Some of the lightest halftones are displayed as white in the brightest modes, yet this defect is inconspicuous. Thus, the MagicBright modes are set up well in the SyncMaster T200 and do not introduce noticeable distortions into color reproduction relative to the monitor’s default settings.
The monitor has three response time compensation modes (the technology is called RTA by Samsung). When RTA is disabled, the response time average is 12.7 milliseconds (GtG) with a maximum of 22.8 milliseconds. In this mode the monitor does not differ from models with a specified response time of 5 milliseconds.
Response time compensation is enabled for some transitions in Mode1: you can see very tall columns (compensation off) standing next to short ones (compensation on) in the diagram. There are no columns of medium height. The response time average is 6.8 milliseconds (GtG) with a maximum of 19.9 milliseconds.
Response time compensation is accompanied with errors, of course. The average level of errors is 4.3%. The maximum error is 44%. RTC-provoked artifacts are not annoying but may be noticeable to the eye.
RTC is enabled for nearly every transition in Mode2 – one column is still tall in the diagram. The response time average is 2.8 milliseconds (GtG) with a maximum of 16.3 milliseconds.
As the number of transitions with RTA is increased, the average level of errors is higher, too. It is 13.9% with a maximum error of 63%. The resulting artifacts are quite conspicuous in games and at work.
It’s hard to tell what RTA mode is preferable. I advise you to try each of them. If you use the monitor for work and movies, you may even want to turn RTA off altogether. From a technical point of view, Samsung’s approach to implementing different RTA modes is interesting: RTA is just turned off for some transitions. Frankly speaking, I prefer the approach of ASUS when compensation is enabled for all transitions while different compensation modes vary in the degree of aggressiveness.
So, the SyncMaster T200 disappointed me with its sloppy color reproduction setup. After the tests of the T190, I had expected the Touch of Color series to be not only beautiful but also good in terms of setup quality.
Let’s check out the other models of the series, though.
