Below are some trouble shooting solutions for a blank target display.

Check the signaling

Verify that the monitor input settings match the output settings of the color corrector's video output signal:

• signal format
• signal range
• EOTF                                      
• resolution
• SDI infrastructure: single/dual/quad link

Dual monitor setup HDR - SDR using an iCMU

If using a dual monitor setup for simultaneous HDR and SDR monitoring, ensure that the 'Dual SDI output' function is enabled in the Resolve project settings.

Note: Some Blackmagic video I/o devices do not support "Dual SDI output" when using RGB 4:4:4 and 12bit. Further, this option requires twice the output resolution. For further info, please visit the Blackmagic Support Center .

 

Using an eCMU

**The Dolby eCMU was discontinued in early 2024, and there will be no further updates provided for this product.

 

If you are using an eCMU for tone mapping, check the following:

• Check the status of your CMU
• Is the CMU in 'black-out' mode? If yes, switch it to normal mode.
• Is the CMU in HDMI tunneling mode? If yes, switch it to SDI mode.
