Bluetooth Trouble because of HDMI-USB-C Converter

[MalikGns]

Hello Everyone, i've got a new Intel NUC i5 10.Gen.

My primary Display got a connection via HDMI to USB C Converter.

My second Display got a conenction via HDMI.

The Problem is that my Bluetooth  in-ear buds get a connection to my Intel NUC but then my primary display shows a black screen. Then i have to reconnect the HDMI Cable which is connectec to the USB-C Converter to get a Signal on my Display. If i disconnect my bluetooth in-ear buds, i get a black screen on my primary display again. 

All Driver updates are done. Does Someone know how to fix the problem? 

Regards 

Malik

Hello MalikGns, 

In this case, as part troubleshooting process I would like you to try the following:

1. Disable the Bluetooth and Wi-Fi from the BIOS. BIOS>Devices>onboard devices> unchecked "Bluetooth" and "WLAN"

2. Were you able to test with the straight HDMI to USB-C? What was the result?\

Please let me know the outcome of this test.

Hey, sorry i had a business trip. 

I checked a straight HDMI to USB C cable, but the problem couldn't be solved.. Still the same.

I did not disabled bluetooth and wifi from the BIOS so far. The question is how to use bluetooth when i disable it from the bios? i need it.

Hello MalikGns, 

In this case, by disabling the Bluetooth and Wi-Fi, I would like to check/confirm if the in-ear buds cause any kind of electronic interference either coming from the HDMI/USBC adapter or the wifi/BT adapter on the NUC.

Do not hesitate to let me know the outcome of this test.

Hello Deivid,

before i disabled bluetooth and wifi from the bios i noticed something..

I have a speakerphone from Byerdynamic whic i connected via usb to my Intel NUC.. and my Monitor showed a black screen again.. so the same problem with my bluetooth in ear headset.

However i disabled bluetooth and wifi from bios and there was no function of bluetooth and wifi on my desktop anymore. I tried to connect my bluetooth in ear headset.. Of course he could not find my intel nuc and my monitor did not show any problems and all signals were there.

Do you have another option to try something out?
