Another title could be : "How to kill displayport on Intel NUC in some click."
I've bought 2 Intel NUC D34010WYKH 2 week ago. The two NUC was working perfectly until yesderday. I used the latest Intel Integrator Toolkit to change the boot graphic. I've done this with other motherboard wihtout any problem until now. I've downloaded the latest BIOS file using the Intel Integrator Toolkit and changed the graphic. After reboot, a bios update failure message appeared on both NUC. After a shutdown, no more video output on DisplayPort. The NUC still boot correctly to Windows. The HDMI port still functionnal (Thanks to my 24inch monitor to be equipped with HDMI port).
Material that was functionnal since 2 week:
2X Intel NUC kit BOXD34010WYKH1 BATCH:CNG6421201 VERSION#: H26248-102
2X Adaptor DisplayPort to VGA : Cable to go #54315
4X different monitor from 15inch to 24inch
I've tried to :
- Putting defaut value in bios.
- Resinstalling lastest bios (WYLPT10H.86A.0026.2014.0514.1714) without any modification to default.
- Plug only Displayport, plug HDMI + Displayport with restart/shutdown between change. Windows only detect the HDMI monitor.
- Forcing the BIOS update with the jumper on board.
- Changing graphics parameter in bios to force Displayport as primary.
- Downgrade bios to 0025, 0024. Will continue the downgrade until the first one in next days.
I don't have any monitor with DisplayPort on it but it was fonctionning perfectly before...
My questions :
- What was to original BIOS version shipped with those NUC? Because this one was working great.
- Wich parameter have changed to make my DisplayPort to disable it? There is any parameter left around after a default setting in bios?
- After a closer look at Intel Integrator Toolkit, I see in the list two similar motherboard model : D34010WYK (Detected as "Installed" by the toolkit) and D34010WYB. Just wondering what is the difference between those two? WYK seem to link to the "kit" and WYB is the "Board". Why they are both in "Motherboard" column in toolkit? It seem to be the same bios list.
Will keep my post updated until I found a solution. Hope someone wil have some good idea to help.
Thanks for reading and sorry for my english.
