LG Flatron L1918S

The response time of 5 milliseconds ISO indicates a monitor that is going to struggle in the low-end sector since this is the value that is usually declared by the manufacturers for modern TN matrixes without Response Time Compensation.

The L1918S has a modest exterior design. It’s got a gray square plastic case and a flat black stand fastened to the screen with a cylindrical plastic tube. It will do well as an office model, but won’t suit people who want to use beautiful things.

Changing the tilt of the screen is the only adjustment option available here.

Fasteners for a VESA mount are available, so you can remove the monitor’s native stand and hang it on the wall, for example.

There is a bare minimum of connectors here: an analog D-Sub input and a connector of the integrated power adapter. A digital interface is missing, but I saw nothing wrong in the image connecting the monitor via its analog interface during my tests.

The position of the control buttons is far from convenient. The designers decided to remove the buttons from the front panel but did not hide them somewhere on a bottom or side edge of the case as usual. You’ll find the controls on the back panel, a few centimeters away from the edge. The buttons are indeed invisible and you can only use them blindly, stretching your hand far behind the monitor. You may even find this convenient if you’ve got extremely long fingers, but I’m not sure about typical Homo sapiens. There are labels pressed out on the buttons – their purpose is obscure since you cannot see them anyway. Perhaps the user is supposed to turn the monitor around to read the buttons, but the stand cannot rotate around the vertical axis.

Quick access is provided to the auto adjustment feature and to selecting a preset mode. The preset modes differ not only in brightness/contrast levels, but also in the value of gamma and in color temperature (in the Day text and Night text modes). Such a wholesale change of settings may prove inconvenient if none of the modes offers settings appropriate for the particular lighting conditions of your workplace.

This is a standard menu from LG, quite handy and without any exceptional features.

By default, the monitor’s brightness and contrast settings are set at 100% and 75%, respectively. To achieve a 100nit brightness of white I reduced them both to 55%. The backlight is regulated by means of pulse-width modulation of the power of the backlight lamps at a frequency of 240Hz. The backlight is uniform, without obvious irregularities.

Color gradients are reproduced correctly, but some noise appears in dark halftones at low values of contrast. It is most likely indicative of an inaccurate implementation of the Frame Rate Control (a means of emulating 24-bit color on an 18-bit matrix). Darks are reproduced normally through all the range of settings while lights merge into white when the contrast setting is set higher than 90%.
