First Look: SyncMaster T220P

While the three previous models had the same specs as other models from Samsung as well as from other manufacturers, the T220P is special at the moment. It is a 22-inch monitor with a Full-HD resolution of 1920x1200 pixels.

This reminds me of the Lenovo ThinkVision L220x that has the same resolution and size of the screen and is also based on an S-PVA matrix. Alas, the T220P employs a TN matrix.

Another notable difference from the T190, T200 and T220 is that the specified response time is now 5 milliseconds (ISO) instead of 2 milliseconds (GtG). In other words, the T220P does not have response time compensation. By the way, every Touch of Color series model with a native resolution higher than 1680x1050 lacks RTC.

The other monitors in this review were taken by us from retail shops at random, but the SyncMaster T220P was provided by the Russian office of Samsung Electronics. Off-the-shelf samples of this model may differ from ours, for the better as well as for the worse. My practice suggests that presale samples sent out for testing often have poor setup. Therefore this is only a preview.

The monitor had 100% brightness and 75% contrast by default. I achieved a 100nit level of white by choosing 45% brightness and 50% contrast. The brightness is regulated by means of backlight modulation at a frequency of 331Hz.

Now that I have mentioned the Lenovo L220x, some samples of it could not produce a sharp picture, but the T220P is free from this problem.

The T220P is a monitor for people with good eyesight. The pixel pitch is small, so you have to move closer to the screen or scale everything up. On the other hand, this property enables the T220P to display images sharply and draw fonts very neatly.

Color gradients are reproduced without defects at the default settings. It is only at a contrast of 40% and lower that barely visible banding appears in them.

The monitor has a standard color gamut. It covers the sRGB color space, being even larger than the latter in greens.

 

The average nonuniformity of white brightness is 5.6% with a maximum deflection of 18.5%. For black brightness, the average and maximum are 6.8% and 25.6%. The pictures based on the measurement results show an X-shaped pattern typical of many monitors.

The gamma curves are very sloppy at the default settings. The blue curve is higher than necessary as its value of gamma is too low. For red, the value of gamma is too high. I hope these are only defects of a presale sample.

The curves have moved closer to each other at the reduced settings, but still do not coincide.

With such gamma curves you can’t expect any miracles from the color temperature setup. There is a few thousand degrees of difference between the levels of gray, which is not only unacceptable for any image editing but even looks unpleasant.

Trying to set the color temperature up better, I lowered the contrast setting to 45%, set the color temperature option (in the Color Tone menu) at Custom and moved the appropriate sliders (in the Color Control menu) into the following positions: R=50, G=35, B=17. You can see the result in the last column of the table above: I didn’t even match the modest result of the above-discussed SyncMaster T200.

The CIE diagram confirms my point: the dot for dark gray does not even fit into my diagram in the Cool mode. There is a small deviation into green in every mode, but it is not a big deal considering the catastrophic difference in the temperatures of grays.

The maximum brightness is about 250 nits. The contrast ratio is about 600:1. These are normal results.

The MagicBright modes are set up adequately. Each is just bright enough for the intended application. So if you select Text, you indeed get as much brightness of the screen as necessary for working in a text-based application under ordinary office lighting. My calibrator cannot measure the dynamic contrast ratio because the level of black is below the calibrator’s measurement accuracy. So I can only say that the monitor’s dynamic contrast ratio is not lower than 13,000:1.

Color reproduction in the MagicBright modes is no worse than at the manual settings, except that light halftones are indistinguishable from white in the Game and Dynamic Contrast modes.

The SyncMaster T220P does not have response time compensation (which is called RTA by Samsung) and its speed is rather low: an average response of 14.4 milliseconds (GtG) with a maximum of 27.6 milliseconds.

Although the results of this sample of the SyncMaster T220P are downright disappointing, nothing is lost yet. It was a presale sample, and I hope the T200P will be set up better when it comes to the market. Sometimes we don’t even publish the test results of a presale product when it proves to be too raw.

From a technical point of view, the SyncMaster T220P may be interesting due to its native resolution. There are very few 22-inch models with a resolution of 1920x1200 pixels. Thanks to that, the monitor allows watching Full-HD video and also delivers a sharper and smoother image in comparison with ordinary 22-inch and 24-inch models. Superbly drawn and elegant fonts, high level of detail, no over-sharpness effect in photographs (this effect is noticeable on monitors with a large pixel pitch) are the highs of the T220P. On the other hand, if looking at small images strains your eyes while the pixel pitch of typical 19-inch models looks normal, you are unlikely to be satisfied with the T220P.
