Scaling
Scaling can be set to Native, Fill, Aspect, and 4:3.
Scaling means changing the resolution of an image.
Native is only enabled when the detected resolution of the source is lower than the resolution of the monitor.
'The monitor has a resolution of 1920x1080 pixel. In case the resolution of the source is lower (e.g. a PAL Video
with 720x540 pixels), when displayed 1:1, there will be a black border around the content.
In case Fill is selected, the content is displayed on the entire screen which, in case the ratio of the source is dif-
ferent from the ratio of the screen (e.g. a PAL Video, 4:3), results in a distortion of the content: with PAL, in hori-
zontal direction, the pixels would be multiplied by a factor of 2.6, whereas in vertical direction the factor would
be 2.0.
With Aspect, the aspect ratio of the source is maintained: in the above mentioned example, the pixels both in
horizontal and in vertical direction would be multiplied by a factor of two, thus the content would have a black
border of 240 pixels both, on the left side and on the right side.
4:3
: if a PAL/NTSC source is connected to an input, the 4:3 setting displays the source without any distortion (e.g.
a circle remains a circle).
