EliteOne G6 800 - Second monitor not detected

[Kun90]

Hi,

At work I changed PC and now I Have a HP EliteOne 800 G6 27 All-in-One Touch, with RTX 2070 Super. The problem is that I cannot connect a second monitor: I have updated all the drivers, I have tried different cables and adapters but the result is always the same, the second monitor is not detected in any way.

I found on the forum that several people have had this problem with EliteOne, but no one has written an effective solution. I tried to connect the monitor via HDMI port, via Display Port-HDMI adapter, Display Port-VGI, I disabled the touch from bios but nothing. Do you have something to suggest to me?

I have Windows 10 Enterprise IoT

The spec page for that PC states that the HDMI port is for input only, so that explains why the HDMI port does not support the monitor function.  It also states that there is a DisplayPort for output, that port should support a second monitor.  If it does not with " different cables and adapters" then I would need to see them identified (make and model number) to make a determination as to why they "do not work"

The manual also seems to identify the DisplayPort for output.  This second monitor - what input types does it support?  and

Make and model?

the second monitor is a Dell, I don't remember the exact model now (I can tell you Monday). It accepts HDMI input and I'm sure it works because I tried to connect the cable to my colleague's computer and it detects it without problems. I have now ordered a USB TYPE C - HDMI cable to see if I fix anything but I doubt it will be a solution.

The spec page linked above indicates the possible solutions

HP USB-C to HDMI 4K Adapter or

HP DisplayPort to HDMI True 4K Adapter

I would suspect that the adapter does not have to be HP but I guess you will find out.

Here is what HP has to say about the HP DisplayPort to HDMI True 4K Adapter

And/or HP USB-C to HDMI 4K Adapter

I solved it by trying with a simple Type C-HDMI cable. Probably the DisplayPort adapter I was using was not compatible, I don't know what else to think. Thank you
