Samsung SyncMaster 245B
Talking about the possible ways to reduce the cost of an LCD monitor I mentioned TN matrixes. Such matrixes boast a low manufacturing cost. They are the cheapest LCD matrix type to manufacture, to be exact. That’s why, even though they have a number of drawbacks, particularly narrow viewing angles, they enjoy high popularity among manufacturers as well as customers. For example, almost all 19” monitors, a large share of 20” models and all 22” monitors come with TN matrixes today. There have been no 24” TN matrixes until recently, though…
So, let me introduce to you the first 24” monitor with a TN matrix. You can see the TN technology at once by the declared viewing angles of 160 degrees as this number is too small even though measured by the reduction of the contrast ratio to 5:1 whereas for other matrix types it is measured by the contrast ratio reduction to 10:1.
The specified response time is 5 milliseconds (measured according to the ISO 13406-2 standard, i.e. on the transition between black and white). From what I’ve learned testing 19”, 20” and 22” monitors with TN matrixes, this means that the 245B doesn’t have Response Time Compensation.
The monitor has a stern black case. Its design has been changed significantly since the 244T and resembles other well-known monitors from Samsung such as SyncMaster 215TW or 225BW.
The stand has got neater. It doesn’t look bulky anymore. As for its functionality, it allows to adjust the tilt and height of the screen and to rotate it around the vertical axis (the whole stand is rotating at that, including the base). The portrait mode is not available, but it is not quite proper for TN matrixes. When the screen is turned around, the poor vertical viewing angles of the TN matrix become poor horizontal viewing angles, which is downright unacceptable.
The stand can be replaced with a standard VESA-compatible mount if necessary.
The monitor is equipped with two inputs: an analog D-Sub and a digital DVI-D. There is a power connector for speakers – our sample of the monitor came without speakers, though. The power adapter is integrated into the case.
The control buttons are placed in the bottom left of the front panel and accompanied with clear and readable white icons. Quick access is provided to the MagicBright modes, to the brightness setting, to switching the inputs and to the auto-adjustment feature.
The Power button is designed prettily. It is larger than the others and has a thin shiny chrome rim that is in contrast with the matte plastic of the case. The middle of the button is highlighted with blue LED. It is mild enough not to distract you from your work, but it begins to blink in sleep mode, irritating some users. You can’t disable the LED in the 245B as this option is only available on a few newest models of Samsung monitors although it has become a standard feature of other brands like NEC or LG.
As opposed to the 244T, the 245B has got a standard menu of Samsung monitors. It is simple, logical and user-friendly. The difference in the menu design must be due not to the screen size but to the video inputs. Samsung monitors with video inputs (215TW, 244T, and the 245T I’ll talk about below) has another firmware with a different onscreen menu.
The setup options are just what you can expect from a mainstream monitor. You don’t have the option of setting color reproduction up by six coordinates or choosing from multiple color temperatures modes here.
The monitor has 75% contrast and 100% brightness by default. To achieve a 100nit white I selected 50% brightness and 54% contrast. The brightness is regulated by means of backlight modulation at a frequency of 180Hz.
