LG Flatron L1810B

This is a newer model from LG Electronics selling at an even lower price – somewhere about $600. The case is as elegant as that of L1800P, but the base lost all its appeal: it now only allows adjusting the tiling of the screen and rotating it in both directions at any angle. At first, I supposed the corbel between the base and the case can change its tiling, thus adjusting the height of the screen (this method is used in the 152 and 172 series from Samsung), but it turned to be stiffly fixed. Of course, this display doesn’t support the portrait mode.

The case is the only evident difference from the previous model: the menu remained the same and there are two inputs (DVI and D-Sub) as well as an integrated 2-port USB hub.

The default color temperature is set up with the same precision as by the previous model, although the deviation in this case is closer to the other side of the nominal – 6150K on white and 6440K on gray.

By default, the brightness and contrast are at maximum. Screen brightness of 100nit is achieved by moving the controls to 41% brightness and 72% contrast. The brightness is controlled by power modulation of the backlight lamps with about 270Hz frequency.

At default settings, the color rendition is nearly perfect, although the level of blue is slightly too high. Thus, calibration without considering the color temperature makes the image warmer due to lower level of blue. And if we take the temperature into account, the image becomes colder – as the initial color temperature is a few hundred degrees lower than necessary.

At 100nit screen brightness, the situation with red is not very nice, but green and blue remain good enough.

The response time as specified by the manufacturer equals 25ms. In practice it is higher – 30ms – even at the maximum contrast (the brightness control of course has no effect on the response time in this model). When the contrast is reduced, the pixel rise time increases to 29ms, thus giving us a total of 45ms.

The screen brightness of this display was 36nit above the promised value. The contrast ratio, however, didn’t rise to the occasion: although it is supposed to be 350:1, the real value is a little above 150:1.

Compared to the previous model, the developers significantly improved the response time. The low contrast ratio, however, spoils the overall impression. Anyway, this display is relatively inexpensive so it can be a good choice for an office, especially if you need a digital input.
