ViewSonic VX724 and VX924
Of course, Samsung was not the only manufacturer to produce RTC-enabled monitors. ViewSonic did so, too. In the market positioning and functionality, the VX724 and the VX924 models (they only differ in the size of the screen) correspond to the above-described Samsung 730BF and 930BF. They have a simple, plain case and a TN+Film matrix with a declared response time of 4 milliseconds (the number of 3 milliseconds has recently appeared; ViewSonic says this number does not imply a new matrix, but that they just measured the response time with more precision and found the average response time to be 3 rather than 4 milliseconds. Thus, there is absolutely no difference between ViewSonic monitors labeled “4ms” and “3ms”). Sometimes you can see the number “5ms” which is not the averaged time of gray-to-gray transitions, but the black-white response (it seems to be the pixel rise time rather than the full response time; for example, the full response time of the above-described monitors from Samsung was about 10 milliseconds, which gives you those 5ms if divided by half).
The case of the monitor should be known to you from our previous reports. ViewSonic often uses it in its inexpensive models. The main disadvantage is that the stand is rather tall, yet you cannot adjust the height of the screen. You may not like it if you’ve got a low chair or a tall desk and you have to look at the screen from below. For example, the screen of the VX924 is 4 centimeters higher than the screen of the 930BF, while the screen of the VX724 is 5 centimeters higher than the screen of the 730BF.
The monitor is equipped with an analog and a digital input (implemented as separate connectors), and an integrated power adapter.
The control buttons are located at the bottom of the front panel and are labeled in ViewSonic’s traditionally incomprehensible way. Instead of the typical labels “Menu” and “Select” or appropriate icons, there are just the numbers “1” and “2”. The functions of the buttons are explained in bottom string of the onscreen menu which looks and behaves like a typical ViewSonic menu.
The monitor provides quick access to the brightness and contrast settings as well as to switching between the inputs. The auto-adjustment can only be started from the monitor’s menu. Note also that if you choose the “sRGB” color temperature setting in the menu, the brightness and contrast settings become blocked.
At the default settings, smooth color gradients are reproduced rather well, although two or three cross stripes can be discerned that should not be there. But if the contrast setting is reduced, there appear more conspicuous stripes. The matrix’s backlighting is rather uniformly distributed on the screen, although on a closer inspection you can note that there are lighter areas at the bottom and top of the screen, near the edge of the matrix.
