The 1:1 mode requires very accurate settings, as even a small sampling error can
cause noise on the output image.
Both the sample clock frequency and phase must be correct to obtain a properly
sampled image.
LED-PRO incorporates automatic adjustments in the 1:1 sampling mode.
On the Input Setup Menu, select Sampling.
Choose either OverSample or 1:1, and press SEL to accept.
1:1 is the default setting.
The OverSample option is only available for RGB and YPbPr analog inputs. All
other input types have defined sample clocks that are inherently 1:1. If the input is
set to one of the other types, the value for this selection will be "n/a."

procedure.
Note For the Auto Config procedure to function correctly, the input
