Sony Multiscan SDM-S73
Externally, Multiscan SDM-S73 resembles SDM-P82 we tested earlier (see our article called Closer Look at the 19” LCD Monitors Features. Part II), but on the whole is somewhat simpler: S73 has no decorations like that metal disc. Compared to SDM-*72 series from Sony, the framing around the screen became much thinner. The control buttons changed proportionally, they are still located to the left of the screen. The base allows adjusting the screen tilt.
There’s only one input in Multiscan SDM-S73 (analog D-Sub).
The Sony’s standard menu contains options for separate adjustment of the matrix brightness and the backlight lamp, three gamma choices, two color temperatures (by default, we have “9300K”, but you can see it with your own eyes that it’s no more than 7500K), plus the user setting (RGB). Quick access is provided for the ECO feature, which allows switching between three presets with different screen brightness (High, Middle and Low, with the fourth ECO mode – User – being just the ordinary user-defined brightness and contrast setup). According to my measurements, “9300K” option gave out a color temperature of 6200K for white and 7350K for gray, and the “6500K” option – 5340K for white and 5970K for gray.
I would estimate the monitor setup to be above average. When Multiscan SDM-S73 displays a one-pixel-wide black-white tessellation, auto-adjustment makes the tessellation look sharp, although there is a barely visible trail behind the mouse pointer.
I’ve got no gripe about the color reproduction. The viewing angles are normal. Again, we have a tincture of yellow when the image is viewed sideways; when viewed from above, the screen gets dark. Still, the effect is not catastrophic, there is no discomfort at work.
By default, the backlight brightness control stands on 100%, the contrast on 70% and the brightness on 50%. The screen brightness of 100nit is achieved by reducing the backlight brightness to 10%, and the matrix brightness to 35%. The brightness of the lamp is controlled by pulse-width modulation with a frequency of 400Hz.
The color curves look perfect, making allowance for the traditionally high level of blue. Well, it is not too high: you can see it from the small gap between the temperatures of white and gray.
The manufacturer claims that Multiscan SDM-S73 has 16msec response time. In practice, though, the response time is 25msec, and the matrix resembles that of the previous monitor, the SDM-HS73, in case of reduced brightness and contrast. Multiscan SDM-S73 was somewhat worse at black-gray transitions, 30msec.
It was also the same with the contrast ratio, only the level of black suddenly grew when the screen brightness approached its maximum (11nit!). Well, it’s all right as the brightness nearly hit 300nit, although was specified to be 250nit. Otherwise, Multiscan SDM-S73 showed an acceptable contrast ratio, 170…200:1.
Well, the testing results make me think that Multiscan SDM-S73 differs from SDM-HS73 mostly in the case design. Their parameters are not identical, but very close. The only difference is that Multiscan SDM-S73 has better color reproduction setup.
