memory and allow the control system to select it without regard to the input resolution. This command
controls whether the input aspect is common to all input resolutions for a given configuration memory, or if
each input resolution has a unique aspect ratio. The command is:
MENU → Input → Options → Aspect Setup → Aspect Set
Genlock
Genlock is used to provide a constant video delay from input to output, and to avoid an occasional dropped
or repeated frame. Unlike older Radiance models Genlock in the Radiance Pro is designed to not increase
switching delays much. So it can be on for Set top boxes and not significantly increase channel change time.
Another advantage of the Radiance Pro Genlock is that the input to output video delay is the same within a
few milliseconds independent of the input and output mode. For example, with Genlock on the input to
output delay for 1080i in to 4k60 out is almost the same as for 24p in to 24p out.
By default Genlock is off. Genlock can be set to off for all input rates, on for only 24p and 25p input rates,
or on for all input rates. The command is:

Scale Bias
Scaling is normally on to adjust the source to exactly fit the output resolution. If the scale bias is set to
“On”, scaling is enabled unless the input and output resolution match exactly. Scaling is disabled/enabled
independently for horizontal and vertical. If the scale bias is set to “Off” scaling is disabled if the input and
output resolutions are close. This is useful when using the Radiance Pro to control aspect ratio for an
anamorphic screen. This case uses Output Shrink and since it is difficult to match the input and output
exactly for the 2.35 input to 2.35 output aspect case, turning Scale Bias to off will insure scaling is disabled
when possible, providing the best possible image quality. The second page of the Status screen indicates
whether scaling is active (Press OK on the remote twice when no Menu is displayed). The command is:

Game Mode
Minimizes video processing latency for playing video games. Interlaced sources 480i/576i/1080i are treated
as 240p/288p/540p, respectively. Deinterlacing is not available in Game Mode. Typically game mode is
enabled for a specific input memory that is then selected while playing games. For games that have a
vertical rate that matches the Radiance output vertical rate, turning “Genlock” on can further minimize video
latency. Game mode is not intended for video/film program material, such as television shows. The

Input Label
Each input configuration memory can be named. Follow the on-screen directions. The

select which input to change and then which character to change. The

arrows change the selected
character. The command is:

Copy Input Settings
This command can be used to copy input setting from one input and one input memory to another input
and input memory, or all input for one memory, or all input for all four input memories. Copying an input
memory to another input memory, copies each resolution sub-memory to the respective resolution sub-
memory of the other input(s). The command is:
MENU → Input → Copy
