OSD

The OSD on the Acer G24 is very simple in design. It opens when the "Menu" button is pushed with a delay of about 1.5 seconds which proves annoying after a time. The status bars are divided into 100 steps, which is not ideal, since the RGB channels are based on 256 levels.

Brightness & Contrast

The Brightness and Contrast menu option is somewhat convoluted in its construction: instead of the setting bars, there are two buttons: "Acer eColor Management", which leads to the empowering menu (like the "e" button), whilst "User" must be selected in order to gain access to the manual brightness and contrast adjustment. The entire procedure requires three button clicks – and as many as six to change the brightness! There is need for improvement here.

The ACM (Adaptive Contrast Management) function consists of automatically regulated contrast. However, in practice, it is hardly noticeable if the function is switched on or off. In the factory settings, ACM is deactivated, although Acer is advertising actively with a dynamic contrast of 50.000:1.

Image settings (analogue)

Here, the image sharpness and refresh rate can be adjusted. This function is only available when the analogue video input (D-Sub) is in use.

Image position (analogue)

This menu point allows the user to change the horizontal and vertical position of the image. Here, too, the function is only available when the analogue video input (D-Sub) is in use.

Colour settings

In the colour configuration, three buttons are displayed: the pre-defined image modes "Warm" and "Cool" as well as "User". This last option leads the user to the RGB channels.

Language

In the menu option Language, the user can select from eight different languages for the OSD. In the factory settings, English is selected.

OSD settings

For calibration, it is important that the OSD is not located in the centre of the screen. In the menu option OSD settings, the horizontal and vertical position can be changed in 100 steps and the display time can be adjusted (between 10 and 120 seconds).
