[Black Screen during show]

ok so there was 1 display server with 4 output, each out put was  2752 w x 1792 h (left and right led screen)  ,  2nd server 2 output each output was  3200w x 1792h(center led Screen),    EDID was set in LED Processor ( H9 Novastar ) as per output,

all content I use HAP, and wav audio file  Converted with Media encoder 2022, all my server are new with high configure, intel I7 with graphic card was NVDI P4000, M.2 SSD,

there was  few content logo loop only, because of its exhibition do not have much content, 3 timeline with each screen logo,  and I have run show for 2 days with same configuration no problem at all, this happen on 3rd day morning when I go on site i see that all my screen was black no one ever touch those setting and my production pc, some how  I run show with plan B with. backup Resolume Arena because no time to troubleshoot,   then by afternoon after restarting many-time, and doing some troubleshoot  suddenly working fine again with same production pc and same display server, so I don't understand why this happen?,  I believe it's because of Watchout dongle?
