Hi everyone

Well I am at a loss for what is going wrong, I have a NUC, this one Buy the PB 33111 Intel 7TH GEN NUC Ultra Compact PC Intel Core i5-7260U 2.2Ghz... ( WKSPB33111 ) online - PBTech.co.nz to be more precise.

I have two 24" screens plugged in, one through a HDMI port and one using an adapter plugged into the USB-C port, I have now tried two adapters and turning down the Hertz on the second screen but nothing that flickering is still there, I have done some research online and the only other thing to try was reinstalling the drivers and still nothing.

Has anyone had this issue and got it solved???

I really don't want to go an mess around trying to get PBtech to resolve the issue!!

Thanks

Dynamic

Hi. I possibly had a similar issue earlier today with a USB-C dock to a 4K screen. I had to turn the refresh rate down to 30hz to get a clean image. Another 4K screen on a 4th gen machine I had to go down to 24hz to get a clean image. How far down did you go and at what resolution?

That Type-C connection is Thunderbolt 3 so it should handle your video output easily. There's usually some trickery involved with TB3, have you checked the Intel website for drivers? & in the UEFI settings too, there's often switches in there that limit TB3 connectivity.

Also, not all USB 3 cables are created equal. Thunderbolt cables are visually identical but have a small lightning bolt icon on each end. IIRC USB-C is 10Gb/sec, Thunderbolt 40Gb/s, but will only output as much data as the weakest part of the system allows.
