Auto Adjust

If an analogue RGBHV signal is being played back, it can be adjusted automatically via the Auto-Adjust function.

Image Adjust

The desired interpolation behaviour is controlled using a function of this menu option. Full-screen playback ("FULL") is also possible, as is scaling with regard to the aspect ratio being played back ("ASP") for playback with square pixels. In addition, the NEC PA241W implements the great strength of the previous model in this area: the scaling can be adjusted to a great extent in the advanced menu using the "CUS" option, for example in order to display signals with non-square pixels, such as those which arise in the SD video sector, without distortion.

The "SHARPNESS" regulator allows the image sharpness to be adjusted even for non-native playback.

In addition, the horizontal and vertical image position can be changed. If an analogue signal is being played back, the image size can also be adjusted.

Color Control Systems

The various image modes or memory spaces on the NEC PA241W can be selected using this menu option. Here, the first difference, and a large one, from the older models, becomes apparent: There are no RGB Gain regulators for adjusting the white point and the user can only enter the required colour temperature in Kelvin. Other settings can be found in the advanced OSD.

Access to the six-axis colour correction remains, but given the extent of the electronics power via the advanced OSD, this should not play much of a role in real usage. In addition, the fact that the correct implementation requires extensive limitations makes things harder. Here, the NEC PA241W behaves the same as the models we have tested from the "90" series to date.

The advanced menu can be called up conveniently from the standard menu using the "ADVANCED SETTING" option.

Tools

Selecting this option controls the Picture-in-Picture functionality in particular. The function for improving the image homogeneity (ColorComp) can no longer be found here. It has been moved completely to the advanced menu.

Menu Tools

The language and OSD settings are collected under this menu option. In addition, the factory settings can also be restored here.

ECO Information

The second last menu option is a purely informative one, with which NEC wishes to surf the "Green-IT wave" along with everyone else. The concrete CO2 and energy cost savings may be contested.
