Datapath X4 - x4 Control Application; Application Installation and Launch; Main Status Screen Overview

The DVI-D Input dialog displays the resolution of the current mode for reference and allows the timings
of the EDID prefered mode to be edited. The dialog supports standard timing formulae such as:
• VESA CVT
• CVT Reduced Blanking
• SMPTE (for HD modes)
• VESA GTF
• Custom
Selecting Auto from the drop down list will typically default to the VESA CVT algorithm which best
matches typical standard VESA output modes. However, to minimise dot clocks and hence maximise
DVI cable lengths, the CVT Reduced Blanking is recommended.
Selecting Custom allows the timing parameters to be edited. It should be noted that you will need to
select between denition of Pixel Clock or Vertical Refresh since these are mutually excusive
parameters.
Once edited, clicking OK writes the prefered mode into the EDID but may not normally aect the input
mode that is being captured. It may be necessary to force the graphics device in the host machine to
detect the new modes, this can be done by selecting Detect on the Screen Resolutions dialog box (Win-
dows® 7) or by disconnecting the souce from the x4 and reconnecting.
All modications to the input settings can be save as a .vqs le, removing the requirement to input the
same settings again. To save the settings select the Save… command in the File menu. To open a saved
.vqs le select the Open… command.
