Samsung SyncMaster 151N (GG15ASAN)

To all appearance, this model is going to replace the out-dated 151S and 151B models in the value sector, while the 152 series will take the more expensive part of the market. The specifications repeat those of the 151S model, but the design is slightly different: 151N inherited a massive base from the 151 series and the front panel – from the new 152 series. The plastic bezel is narrower, and the control buttons moved down. However, the buttons are small and hard to press. Moreover, this model, just like 151S, has only two quick-access buttons – for brightness and image self-tuning. The power unit is internal.

The comments about the viewing angles are the same as we made for the previous model: the upper part of the screen is darker when you look at it from below and this causes some discomfort in the portrait mode. There is a big reserve of brightness and contrast. Subjectively, most comfortable settings for work were 70% brightness and 45% contrast.

This display performed worse in our response time tests than the 151S model: 40ms in total, a very long rise (36ms) was followed by a very short fall (4ms).

One more difference from the previous model: at low brightness we saw the modulation of the power supply for the backlight lamp with a frequency of 540Hz.

Samsung SyncMaster 152B (SDS)

This display represents a new series from Samsung and features new design. The power unit is taken outside, which made the case slim and light. The elegant-looking base allows adjusting both the height and skew (from vertical to horizontal position). When the screen is positioned horizontally, the base is in fact folded up and you can hang the display on the wall (mounting screws and other necessary items are included). The cables are now attached to the base, not to the display, which is more flexible. Overall, this display seems to have the best case among all the considered models: a stylish and handy design. Unfortunately, they had to sacrifice the portrait mode for that: the new base cannot be rotated to the portrait mode at all. So, the second letter in the model marking no longer indicates the base type, it now stands for the availability of built-in speakers (Z) or their absence (D).

The specified characteristics are astonishing: 25ms response time, 160/150 viewing angles, 350nit brightness and 450:1 contrast. In practice, the image is perfectly seen even when your line of sight is nearly parallel to the screen. But when you look at it from below, there is the same problem: the upper part of the screen looks dark. Still, as the display cannot be used in the portrait mode, it is no big inconvenience. Working in a brightly lit room, we set brightness and contrast to 40%.

The buttons on this model can be easily pressed, but the quick-access button for contrast is not here.

This display showed the same response time as SyncMaster 151S – 31ms (25ms – light-up and 6ms - fadeout).

At low brightness, we could see the modulation of the backlight lamp with a frequency of 1kHz.
