I have experienced problems to send 4 outputs [email protected] . The computer recognize the 4 outputs , but when i start a watchdog the screen remains in black and the ip and logo don't appear! I set the producer preferences to 30HZ , to 29,97 ...... test all frequency rate. But when i use 3 outputs , all works fine , or even i use 4 outputs on [email protected] too work fine! Has any limitation in WO to do 4 outputs? I've experienced the same trouble in WO 5.5.2. The system is running with FirePro W8100 , I7 5930X and Intel 750 series PCI SSD .
