Hi - I've used Black Magic Design HDMI-SDI converter pairs for years with no problems. But in a new installation, my screens are randomly going blank.
The setup -
- two Mac Studio M2's with direct connected HDMI monitors.
- six Black Magic HDMI-SDI Micro converters pairs (three per computer).
-- Four new G3 converters and two original converters.
- six 70' 4k LED screens (Sony and Insignia, three per computer).
- brand new 3G/6G Belden 1694A/Canare BNC cable runs of 100' (three) and 200' (three).
The Symptoms -
Everything boots up fine and I see desktop images on all six screens. Within approx 10 minutes one of the screens will go blank without displaying a "lost connection" message. The image can be restored to the screen by unplugging/replugging the thunderbolt adapter at the computer. Other details -
- It is never the same screen(s) that goes blank or the same pattern.
- Multiple screens never go blank at the same time. One might blank after 5 minutes and then another after 3 more minutes.
- It happens both on the Sony and Insigina displays
- Screens from both computers have randomly gone blank.
- It happens on both the 100' or 200' cable runs
- happens on both the G3 and non-G3 converters
- Never more than 3 screens have gone blank at a time and never all of the screens from one computer.
- Screensaver and power saver settings are off on both computers
- Remote desktop into the macs show the blank screen desktops as active.
- The direct connected HDMI computer display never goes blank.
- When the thunderbolt/HDMI adapter is unplugged from the computer, the screen shows "lost connection", meaning that the screen is getting some sort of signal.
- When the thunderbolt/HDMI adapter is replugged into the computer, the desktop image comes back on the screen
Any ideas? Thanks!
