NUC i815BEH HDMI firmware update not working.....

[jsmiddleton4]

Trying to run the HDMI firmware update tool.  Says can't connect to system? 


See attached.

What am I doing wrong or is this the way its telling me the update isn't necessary?

Same system can't message when just trying to check firmware.

1. Is your monitor ON and connected to the HDMI port?

2. When you launching BobcatAuxISPTool.exe tool, did you select Run as administrator?

Yes to both.

Hi, I believe it is necessary to install the last version of Intel Graphics DCH Drivers (not legacy), but I ask the experts for confirmation.

[jsmiddleton4]

Anything is of course possible.  Given the update was released prior to those DCH drivers it seems unlikely.

My NUC is one of those with only one HDMI port.  Maybe the update gets confused when that's the case?  Who knows......

[LucF]

I meant the Intel Graphics Drivers must be DCH.
If legacy driver is installed, the update does not work (I believe).
I had the same problem with my NUC (only one HDMI port) and installing DCH driver I solved it.

Bye

Doesn't say DCH but it is the driver from 9/2021. 

The Download page refers to it as the DCH driver. 

I installed it before trying the HDMI firmware update.

Thanks David but I figured it out on my own.  In the BIOS the video has to be set to AUTO.  Since I'm only using HDMI I had set it as the main and only output.  Once set to AUTO, HDMI firmware ran as expected.
