BI v5 Video smear issues

[Marshall]

Ever since I upgraded to v5, it looks like a lot of my cameras are showing like a dragged line of movement. still images are fine, but people walking or cars moving are smeared. It's almost like it's an I Frame setting but it didnt do it before, nor does it appear on the NVR. I also tried changing the I frame with no luck. Thoughts? Image attached of what it looks like.

Until recently I've never heard that the GPU would go unused unless there was an active monitor (or fake display emulator) was connected to the system.

Disabling power management for the graphics card and display, my BI system appears to make use of the GPU.






Is there description somewhere that explains the technical reasons why there must be an active monitor?

thx

Have no idea why there needs to be a monitor for the card to work as a graphics processor. It is just knowledge picked up reading, but no explanation.

Must be related to power management on some hardware or even newer hardware. Maybe it detects no monitor so switch the bits of the vid card off?
