Dualscreen "no signal" with NUC7i5BNB with newest bios etc on two 2K monitors usb-c to dp 1.2

Hi there i got recently connected my nuc NUC7i5BNB with the latest bios 0072 and drivers on a updated win 10 machine with two 2K screens the AOC Q3279WG5B with this cable https://bit.ly/2GbbsWb

If i connect the second screen i get a no signal notification on the second screen connected with usb-c to dp 1.2 both running at 60hz if i unplug the usb-c cable from the nuc and plug it back in the second screen is working again. For me i need a solution for the unplug and replug the cable all the time i dont have a spare cable to test by the way.Everything with the latest drivers

I am hoping that Intel Customer Support has a setup for testing this scenario; I do not. My two 4K TVs are not within cable distance of each other and are both HDMI, whereas this test requires one to be DP.

Hi jingaling, Thank you for posting in the Intel® Communities Support. Is this a new NUC? Did you make any recent hardware/software changes? Was it working fine before? When did the issue start? If you use a single monitor, just the one that is connected to the USB-C port, is the problem the same? Did you switch monitors to rule out a possible problem with one of them? You mentioned that you do not have a spare cable to test, but keep in mind that the problem might be the cable itself, so if you can try that it will be very useful. Please try to install driver Intel® graphics driver version 24.20.100.6286: https://downloadcenter.intel.com/download/28208/Intel-HD-Graphics-Driver-for-Windows-10-for-Intel-NU... If the problem persists, we can try the Intel® driver version DCH 25.20.100.6519: https://downloadcenter.intel.com/download/28515/Intel-Graphics-Driver-for-Windows-10?product=98911 Regards, Alberto R.

yes a new nuc no jest an new ssd and windows 10 64 bits,

i didnt have a second monitor before

 

i tried the both drivers but still the same issue

 

I tried to boot up just one monitor with the usb-c to dp cable connecting to the nuc but also with one monitor connected i had to replug the cable after that i get my signal back and also tested that with the second monitor same problem.

 

Does that mean that it is the usb-c to dp cable mailfunctioning?

It would seem to be either the cable or the monitor itself.

jingaling, Yes, it could be the cable or even the USB-C port itself, if it is possible to use a different cable, that will be a good thing to do, it will help us to rule out that possibility. Regards, Alberto R. Intel Customer Support Technician Under Contract to Intel Corporation
