The menu offers five color temperature values: “6500K” (the measured temperatures of white and gray are 5660K and 5920K, respectively, when this setting is selected), “9300K” (this setting produces 8570K white and 8920K gray colors), one unlabeled position to the left of “6500” (it gives out 4980K white and 5070K gray), and two unlabeled positions between “6500” and “9300” (one corresponds to 6320K white and 6490K gray, and the other to 7640K white and 7900K gray).

After that, of course, I wasn’t surprised at all to see that the viewing angles, color reproduction and adjustment of the analog signal of this monitor were the same as with the previous two models. There were no problems, save for a small lack of the vertical viewing angle, typical for TN+Film matrixes.

The gamma curves indicate just one defect – the monitor cannot reproduce some dark-blue colors. However, this defect doesn’t aggravate as you reduce the brightness or contrast settings (which is natural, since the brightness is controlled with the backlight lamps, rather than with the matrix), causing no serious troubles. Moreover, considering that this monitor is overall the same as the L1730B which doesn’t have such a defect, I suspect that this problem is peculiar to this sample only, rather than to the entire series. Otherwise, I have no complaints about the color-reproduction quality.

The response time didn’t make it to the promised 12 milliseconds. Moreover, it is higher than with the L1730S and L1730B, so I’m quite confused about the loud advertisement campaign of these models where their ultra-fast response time of 12 milliseconds is much touted. The contrast ratio and the maximum brightness of this model are better compared to the junior models, but the difference is actually small.

Thus, the portrait mode and the accompanying two-port USB hub are the only advantages of the L1730P over the L1730B. These two models differ by $20-25 in price, which is more than the price of an externally-powered 4-port USB 2.0 hub, so you should only prefer the L1730P for its portrait mode. If this mode isn’t important for you, there’s no sense in shopping specifically for an L1730P.
