Hi all ,
Last year we have purchased a Windows PC ( HP Z420 Workstation "600 Wat" + Radeon HD 7870 Eyefinity 6 + Windows 7 pro Sp1) , and we have 6 screen (Nevo L-W22 ) connected to this PC (with 4 Active & 2 Passive mini Displayport adapters to HDMI ).
This system is used as a digital display video wall, this means no users log in to this computer. The computer shows a web page on each screen after an automatic logon.
We still have a problem with this system, and we would like to ask your advice.
The problem is that not all screens turn on correctly after a reboot of Windows. In most cases, all 6 screen are detected, but in other cases, only one screen (main display) is detected after a reboot.
The problem usually occurs during the weekend. We have modified the setup of the PC, so that it will automatically reboot each morning at 06:00h.
We have seen that the screens become disabled after a long time, usually after more than 24 hours. For that reason, we forced the reboot after 24 hours. But even then, we noticed that the screens are not working during the weekends. The only workaround is to manually turn on each screen (pressing the On/Off button) on Monday morning.
Do you have an idea why these screens turn off, or fail to turn on again after a reboot?
Can you give me any suggestions please?
