LG Flatron L1811S

This is one more display from LG, resembling L1810B in its exterior. Its retail price is approaching $550. To drop the price, the company pulled out the DVI input and the USB hub. There’s only one D-Sub left. The base, like in the previous model, allows tilting and rotating the screen.

The settings menu is analogous to that of the previous model and the brightness and contrast are at maximum again. My reference screen brightness of 100nit is achieved by setting 55% brightness and 60% contrast. The brightness is controlled by power modulation of the backlight lamps.

The color temperature is set up properly. By default, it is 6480K on white and 6610K on 50% gray.

Color curves are close to the ideal. They only go a little higher than necessary on light tones, but this doesn’t affect the dynamic range, as there is a sufficient reserve. Unlike the previous displays, this one has an overstated level of green rather than blue. So, without calibration, the gray color has a slight greenish tint.

The picture we see at 100nit screen brightness looks similar to the previous display, with a single exception: the level of green is too high, while the level of blue is too low. Overall, this display has excellent color rendition capabilities.

The specified response time is 30ms (15/15ms), which fully complies with what we see at the maximum contrast. However, when the contrast is reduced to 60%, the pixel rise time doubles to 30ms and the full response time this way equals 45ms.

The measured maximum brightness exceeded the specified value by 28nit. The contrast ratio is better here, although doesn’t reach the promised numbers, too.

Flatron L1811S looks much similar with its predecessor in terms of technical characteristics. The contrast ratio is better, although it is still not perfect. The lack of the digital input makes this display cheaper. So, if you are choosing a display from LG’s Flatron line and don’t need the DVI input, consider this model.
