The monitor has 90% brightness and 80% contrast by default. I achieved a 100nit white by selecting 55% brightness and 58% contrast. You should not raise the contrast setting above 80% as it leads to a loss of light halftones. The brightness is regulated by backlight modulation at a frequency of 209Hz.
The color gamut is typical for a modern monitor that uses backlight lamps with ordinary phosphors. It roughly corresponds to the sRGB color space.
The average and maximum brightness uniformity is 5.8% and 15.5%, respectively, on white. On black, these numbers are 8.4% and 22.6%, which is not quite good. As the pictures above show (I want to remind you that those are not photographs of the actual monitor, but pictures that illustrate the distribution of brightness on the screen), the corners and top of the screen are dark on the white background. On the black background, there are light streaks along the top and bottom of the screen.
The gamma curves are rather neat at the default settings, being close to the theoretical curve for gamma 2.2. The blue curve is somewhat lower than necessary but not too much.
At the reduced brightness and contrast the curves almost coincide with the theoretical curve.
Lacking Response Time Compensation, the monitor is rather sluggish with a response time average of 13.1 milliseconds GtG. Most of the transitions are as slow as 20 milliseconds. The monitor is only really fast at switching into pure white or pure black.
The color temperature is set up quite accurately. The difference between the temperatures of different grays in never higher than 500K (except for the User mode with the default settings).
Interestingly, the calibrator reported the same value for the Warm and sRGB modes but they actually produce differently-looking images. The image in the Warm mode is not white but greenish. The calibrator reported the same value as in the sRGB mode because the term color temperature can only be applied to white but not to green and the calibrator couldn’t count this in. If you are interested, I can tell you the color coordinates (CIE x, y) of the white point: 0.313 and 0.345 in Warm and 0.313 and 0.344 in sRGB mode. As you can see, they only differ with the vertical coordinate, which means a shift towards greens.
The monitor’s brightness and contrast are quite typical for modern models of this class.
The VW202S features ASUS Splendid technology – a set of predefined modes you can switch between by means of a single button. The most notable difference from such technologies offered by other manufacturers is the possibility of changing and saving the monitor’s settings in each individual mode. In many other monitors there is only one user-defined mode and the others are not editable. Each group of Splendid settings can be reset to their defaults apart from the others by entering the main menu and choosing the necessary group on the first tab.
As you can see, the values of brightness and contrast are almost identical in each mode by default. So what is different? Color reproduction.
The red and blue curves are lower while the green curve is higher than the theoretical curve. I really don’t know why a theatrical picture should be greenish. The same goes for the Scenery mode except that the level of green is even higher and reaches saturation in lights whereas the curve is still sagging in darks.
It’s funny in the Game mode: the monitor doesn’t display darkest halftones at all (it is the bottom left of the diagram). Up to the middle of the diagram reds and blues are darker than they should be, but then the corresponding curves rise up suddenly up to saturation. The level of green is too high again.
The Night View mode is expected to ensure good visibility in dark games by making all shadows brighter. The previous modes deprive the user of shadows altogether while the Night View mode just shows them: the measured curves coincide with the theoretical one in the bottom left of the diagram. In the right part of the diagram, green is too intensive again.
So, the Splendid modes prove to be rather stupid by default. They only bring various distortions into color reproduction unless you manually configure the monitor in each of them. Unfortunately, the manufacturer bound some features, particularly the dynamic contrast mode, the sharpness and saturation settings, to Splendid technology. These settings become inaccessible in the Standard Mode.
- Neat exterior design
- Good color reproduction setup
- No DVI input
- Slow matrix
- Irregular backlight on black
- Inconvenient menu
- Poor setup of Splendid modes by default
- Text-based applications (documents, spreadsheets, Internet)
- Viewing and simple editing of photographs
- Movies and games that don’t require a fast matrix
