REVIEW: LG Flatron W2363V Part 5

Beside the basic controls for brightness and contrast, there are even more advanced settings such as gamma, black level and white balance. The impacts of these controls are complex, they should only be changed using a colorimeter.
The color menu also surprises pleasantly: the free color adjustment with separate RGB controls is completed by five presets located on a color temperature scale. Three of them have meaningful descriptions: sRGB, 6500K and 9300K. Their true color temperatures and the differences between the sRGB and 6500K settings will be examined during our calibration procedure. Self-created user presets cannot be saved.

The color menu reveals why LG marks both HDMI inputs as "optimized for AV equipment, not supported for PC": a detailed color management is available for DVI and VGA only. The HDMI inputs, however, are restricted to hue and saturation controls. It is therefore recommended to always connect a PC via DVI, even if a HDMI output is available.
A further extra feature is the PiP mode. While the first image source is displayed on the full screen, a second source is displayed in a smaller inset window. While working with an office program or playing a game (main screen), you could at the same time keep an eye on a TV show running in the PiP window.
The main picture comes from the signal source, which has been set with the Source button. The input signal for the PIP window is selected in the SETUP/PiP menu. After the OSD has been closed you can turn the PiP window on or off by pressing the "arrow up / PiP" button. The button "arrow down / Swap" allows to swap the inputs for the main and sub-screen back and forth.
PiP input source combinations.
The inserted picture is processed by the electronics of the monitor, so there is no reason to expect problems with display drivers. On the other hand, the user has not much impact on the sub-screen: four cornered positions, fixed size, that’s it. In addition, some signal combinations are not allowed (e.g. 2 x HDMI), and both HDMI inputs accept only PiP RGB signals (no YPbPr mode).
Due to the limitations of the technology, TN panels only provide a colour depth of six bits, which is why colours that are not supported have to be dissembled through dithering. That way, despite the limited colour depth, it is possible to obtain more or less consistent colour gradients, which of course depends on the quality of the implementation. If dithering is not that successful, the image shows patterns or flickering colours.
