The monitor does not have a menu or some numerical indication of the selected brightness value, so I tested it at the minimum and maximum brightness. A handy feature, the LED in the Power button begins to blink on your reaching a brightness adjustment limit, thus showing you that there is no sense in pressing the button any longer.
Brightness is controlled through pulse-width modulation of the power supply of the backlight lamps at a frequency of 240Hz. The modulation is performed even at the maximum brightness.
Subjectively, the image quality is good. The backlighting is uniform. Color gradients are reproduced flawlessly.
The SyncMaster 305T uses ordinary backlight lamps and its color gamut is just a little better than the standard sRGB: the red dot is located differently and green is reproduced better. This is good, but the color gamut triangle is still much smaller than with the above-described 275T. Samsung has promised to release an updated version of the monitor in the second half of this year with WG-CCFLs and an extended gamut.
The gamma curves are acceptable. Red and green are close to the ideal curves, but blue is too low.
Color temperature is set up quite accurately. The monitor deflects much from the standard 6500K on darkest tones only.
The monitor’s average response time is 9.5 milliseconds, and the matrix is slow on dark transitions, almost to 50 milliseconds, which is a rather typical thing with *VA technologies. The fastest transition takes only 4 milliseconds.
Alas, the good response comes at a cost. The RTC error is 5.6% on average with a maximum of 47.2%. This is not very much. For example, the average error may amount to 15% with TN matrixes and the artifacts are indeed conspicuous then. On the other hand, the above-described 275T has almost the same response (and without the increase on darks) but its RTC artifacts are five times smaller.
Contrary to my apprehensions, the 305T’s brightness adjustment range is selected very appropriately: from 74 to 256 nits. The bottom limit suits for work even in a dim room without your having to reduce the screen brightness further by means of the graphics card. The top limit is more than enough for work under bright sunlight.
Curiously, the calibrator could not even measure the level of black at the minimum brightness, always showing zero.
Thus, the SyncMaster 305T is not an ideal product. It has its drawbacks, in functionality (only one input; no user settings and the lack of the MagicBright feature; inconvenient placement of the USB hub ports) as well as in setup quality (inaccurate gamma curves, a growth of the response time on darks). On the other hand, none of the drawbacks is a real problem. Most users won’t even notice them. The brightness adjustment range is wide enough to adapt the monitor to any reasonable conditions.
Although the 305T is mainly intended for work that requires a large screen and a large display resolution, its parameters make it suitable for use as a home monitor, for playing games and watching movies. It offers enough brightness and speed for such applications, too.
