The two senior models – 24-inch and 26-inch ones – differ from the above-discussed monitors not only with the size of the screen. They also feature a HDMI input and an integrated USB hub.
HDMI is nothing really new (just as HDMI-DVI adapters), but the T240 and T260 are among the few models that offer full support for audio-over-HDMI. Although these monitors do not have integrated speakers, they can output the sound they receive via HDMI not only in analog but also in digital format, via optical S/PDIF.
The monitor has 100% brightness and 75% contrast by default. To achieve a 100nit white I lowered the brightness and contrast settings to 40% and 45%, respectively. The brightness is regulated by means of backlight modulation at a frequency of 180Hz.
The color gamut is perfectly standard. The ToC series uses neither LED backlight nor lamps with improved phosphors, and every model from this series has a color gamut that is overall similar to sRGB.
The average nonuniformity of white brightness is 6.3% with a maximum deflection of 22.2%. For black brightness, the average and maximum are 6.8% and 25.6%. Not very good results: the sides of the screen are dark while the bottom is bright.
The gamma curves are acceptable at the default settings. The blue curve just sags a little.
At the reduced settings the curves improve and coincide through most of their length.
The T240 is just as good in terms of color temperature setup as the T190 and T220: the difference between the levels of gray is not higher than a few hundred degrees, which is an excellent result for a home monitor based on a TN matrix.
The T240 doesn’t require manual adjustment, yet I set it up for a color temperature of 6500K as required by the sRGB standard. To do this I set Contrast at 70% and set the color temperature sliders as R=50, G=43, B=42. You can see the result in the Custom column of the table above.
The CIE diagram testifies to the high accuracy of the monitor’s setup. If you feel like fault-finding, you can note the small deviation of the white dot into greens in the Normal mode, but this effect can’t be noticed with a naked eye. Moreover, it disappears if you reduce the monitor’s Contrast setting.
The max brightness and contrast ratio are perfectly normal. The above-described manual setup lowers the maximum brightness just a little.
The MagicBright modes agree with their respective names. The Text mode is meant for good office lighting, though. If you are working with text at home under dim ambient lighting, you may want to adjust the monitor’s contrast and brightness settings manually to reach a comfortable level and use the MagicBright technology for viewing photos, watching movies and playing games. The monitor’s dynamic contrast ratio is no lower than 13,000:1.
The T240 does not have response time compensation and its speed is rather low as the consequence. Its response time average is 14.6 milliseconds (GtG) with a maximum of 28.2 milliseconds. This is quite enough for office applications, movies and not-very-dynamic games, but devoted gamers may want to prefer a faster monitor.
So, the T240 is a good product, boasting not only the pretty looks typical of the ToC series but also superb setup quality. Its only downsides are the rather high response time and the notable nonuniformity of brightness.
