Problem Solution Notes
Scopes refreshing slowly Displaying 1 traditional scope window
instead of 2 will greatly increase scope
update speed. Normal update speed
with a single scope active is approxi-
mately every other frame.
Unlike the other scopes, Real Time
Scopes will update every frame.
Scope refresh rate is governed by
available processing power.
External audio leads video Setting Processing to Fast Mode on the
Video Menu can reduce video delay.
You can also use the monitor’s audio
out to ensure perfect audio/video sync
as disembedded audio is always de-
layed by the exact amount of video
processing time.
Image is ickering On OLED units verify that Flicker Free
Mode is turned ON.
With all monitors verify the frame rate
being received on the System Status
menu. If interlaced the icker may be
normal and part of the signal.
Image not as sharp as desired or
sharper than desired
Adjust sharpness level from the Video
Menu or use the Max Sharpness func-
tion.
No articial dithering or image en-
hancement is applied to the image by
default.
Temporary Image Retention (LCD only) Image Retention on LCDs typically
only occurs when monitoring interlaced
footage as interlaced (I->P Mode set to
Motion Compensated). To prevent TIR
the I->P Mode on the Video Menu can
be set to Inter-Field, which will show
the image on screen as progressive
instead and prevent TIR from building
up.
If TIR has developed it will automatical-
ly begin to dissipate once you send the
monitor a progressive signal.
LCD monitors can develop a type of
image retention that may be seen as
an after image or lines on the screen.
This is not burn-in and is not perma-
nent. It typically only occurs with pro-
longed viewing of interlaced sources
as interlaced (Motion Compensated
I->P mode).
The longer an interlaced signal was
monitored in Motion Compensated
mode the longer it will take for the TIR to
disappear, but TIR will always resolve
over time provided that a progressive
signal is used or the I->P mode is set
to Inter-Field.
