3.5.3. 

Optimize for Display  

Settings: DVI forced, Optimized, DVI/HDMI 

Internally, the display interface processes data at a full ten bits per color. The color depth on the DVI-D 
output  is  determined  by  the  supported  standard  of  the  attached  monitor  or  device  when  set  to 
DVI/HDMI. For DVI 1.0 and HDMI 1.1/1.2 devices it is 24 bit, for HDMI 1.3 compliant devices it is up to 
36 bit.  

DVI  forced  will  output  with  24  bit  color  depth  irrespective  of  the  supported  standard  of  the  attached 
monitor.  

When  the  Optimized  setting  is  enabled  the  output  resolution  is  automatically  set  to  the  native  screen 
resolution of the attached display if the Aspect Ratio menu item was chosen to Scale or when no input is 
detected. The color depth is determined in the same way as when set to DVI/HDMI. 

 

3.5.4. 

DVI Range  

Settings: Default, Limited, Full

 

When  set  to  Default  CEA  output  modes  have  limited  range,  and  VESA  modes  have  full  range.  An 
incoming limited range mode is either passed through when the output is set to a CEA output mode or 
expanded when the output is set to a VESA mode. An incoming full range mode is either compressed 
when  the  output  is  set  to  a  CEA  output  mode  or  passed  through  when  the  output  is  set  to  a  VESA 
mode. 

If  the  HDMI/DVI  output  does  not  behave  as  expected  because  the  HDMI  display  is  not  evaluating 
AVInfoFrames properly, the range can be changed manually.  

A limited video range uses the following greyscale for video information - 8 Bit System: 0x10 .. 0xEF, 10 
Bit System: 0x040 .. 0x03BF, 12 Bit System: 0x100 .. 0xEFF.  

 

3.5.5. 

Frame Rate  

Settings: 60 Hz, 50 Hz, 48 Hz, 24 Hz, Auto 

In auto mode the output frame rate follows the input frame rate.  

Signals with 24Hz, 25H, 48Hz, 50Hz input modes get special treatment, modes with other refresh rates 
are displayed at 60Hz.  

24Hz input modes will be output at 24Hz if the output resolution is set to either 720p or 1080p and the 
Frame Rate setting in the Output Config menu includes 24Hz and 48Hz.  

24Hz  input  mode  is  displayed  at  60Hz.  48Hz  input  modes  will  be  output  at  48Hz  if  the  Frame  Rate 
setting option in the Output Config menu includes 48Hz.  

Otherwise it is displayed at 50Hz.  

A 25Hz input mode is output at twice the frame rate 50Hz.  

An  exception  to  the  24/25Hz  input  mode  treatment  is  if  the  output  resolution  is  set  to  480p.  480p  is 
always run at 60Hz output rate. 

50Hz input modes are displayed at 50Hz output rate. 

The output frame rate can also manually set to 24Hz, 48Hz, 50Hz or 60Hz  

Only 720p and 1080p output modes are available with 24Hz refresh rate.  

The 480p output mode is only available at 60Hz refresh rate.  

For all other modes 48Hz, 50Hz and 60Hz refresh rates are available.
