Operation
46 Runco CL-410 and CL-420 Owner’s Operating Manual
Blue Enable: Refer to Blue Enable on page 42.
Splash Screen Timer: Press the right- or left-arrow buttons to set the Splash Screen
Timer. This timer controls how long the startup (ISF and Runco logo) image stays
on-screen after you turn on the projector. Select from 15 to 60 seconds, in 5-second
increments.
Noise Reduction: To apply Digital Noise Reduction (DNR) to the input signal, select
Noise Reduction from the ISF Calibration menu. Noise reduction is useful for clearing up
noisy RGB images such as those from a PC. Adjust as desired using the left- or
right-arrow buttons, keeping in mind that reducing noise (which reduces high frequencies)
may also “soften” the image.
