It seems that we’re seeing a random issue, where 5010s are displaying this error when connected to Dell P2417H monitors. I THINK it’s related to upgrading to firmware 8.6_206, but, not positive yet. Has anyone come across this?
Today our techs have to fix it manually, by changing the frame buffer settings in the BIOS.
We don’t force a resolution through WMS, and as far as I’m aware, the deployment team doesn’t change anything on the monitors. Whatever it’s set to out of the box.
In the end though I think we found the issue. A lot of our 5010s were deployed years ago with a VGA to DVI adapter. Upgrading from 8.5_017 to 8.6_206 in our WMS migrations seems to have triggered an issue with those. When they switch to just go straight display port end to end, the issue is resolved.
