Samsung SyncMaster 191T (GH19BSAN)
The exterior of this model resembles that of the previous one. However, all models of the “T” series are equipped with both analog D-Sub and digital DVI inputs. This is the main reason for 191T to cost about $40 more. This display supports the portrait mode, too.
The menu is the same as in 191N with one addition – you have the option of switching between the two video inputs. Besides, the buttons are stiff and hard to press.
By default, the display has 80% brightness and 50% contrast. To achieve the screen brightness of 100nit, I set 30% brightness and 20% contrast. The brightness is regulated by modulation of the power of the backlight lamps with a frequency of 500Hz or higher. The color temperature is set up worse than in 191N: my measurements showed 5530K on white and 6520K on gray with the “Reddish” option and 5820K and 7730K with the “Bluish” option. Thus, I may suppose that the display will have the blue color pulled up – that’s why the color temperature on gray is overstated.
Indeed, the measurements proved that the level of blue is too high on gray. At the same time, it is red that is high on light tones, close to white. Moreover, the display doesn’t distinguish some of red tones. This situation is worse than if we had just one color set too high, because we cannot cure it by adjusting the RGB levels in the display settings. A correct color profile may only help us here.
When the brightness is reduced, the situation improves: blue is still too high, but red fits into the norm.
The response time was a little higher than by SyncMaster 191N: 26ms. It didn’t depend on the contrast setting, also.

This display couldn’t repeat the miracles of its predecessor as far as the contrast ratio is concerned. It is not bad, but doesn’t even reach the specified 500:1.
I expected this display to be no worse than 191N, but this didn’t happen: the poor color rendition and contrast ratio spoiled the day. Nevertheless, SyncMaster 191T is a good choice due to its relatively low price.
