Cable matters usb to hdmi not working mac drivers#
It's a strange one this, but after your comment about only installing the DHC drivers and not the legacy Thunderbolt drivers, I decided to do the following:ġ. Hello, and thanks for taking the time to respond. Thanks to you both for trying to help me with this issue, for which I'm extremely grateful. Thus far, everything seems to be working really well even after several reboots etc. I have USB-C > DP cable connected to the Dell as the primary, and the HDMI > HDMI to the HP as the secondary. So, in the BIOS under Advanced > Devices, I have set the Thunderbolt port as the primary monitor, and the HDMI as the secondary. TechGuy, interestingly, the USB-C to DisplayPort cable connected to the Dell was causing the monitor to turn on and off, but disabling DisplayPort 1.2 in the monitor's setting resolved this. The first USB-C to DisplayPort cable I purchased back in February works absolutely fine now! I simply had to turn off the NUC, and then use a screwdriver to short the power connector as shown here Thunderbolt™ 3 Legacy Driver for Windows® 10 for Intel® NUCĬan someone please kindly advise on this issue as I would really appreciate some help with this. Thunderbolt™ 3 DCH Driver for Windows® 10 for Intel® NUC Iris Plus Graphics 655 Driver Version: 27.20.100.8673ĮDIT: Just to add, I have installed the thunderbolt drivers below. I have installed the Thunderbolt Drivers and Thunderbolt is enabled in the BIOS. Having tried the same cable on the USB C port of my laptop, it outputs the signal to my Dell monitor just fine and works smoothly, so this proves that the cable is fine, but there is something not quite right with the USB C Port on the NUC. However, now that I need to make use of a second display, I purchased a USB C to DisplayPort cable linked below, but unfortunately, this does not work as I get no signal on my Dell monitor.

It might be worth seeing if has USB-C drivers specific to your machine (you can get the Thunderbolt drivers from there), and then if not, check Windows Update and see if it's surfacing any driver updates, you can use Windows Update Minitool to transparently see which driver update might need to be installed.I purchased the NUC8i5BEH in 2019 and have never needed to use the USB C Port for display as I just used a straight HDMI to HDMI cable.

If you suspect other driver issues, then first check if Windows's own USB-C driver is loaded (UcmUcsi.sys), you can do this by opening up Device Manager and then looking for "UCSI USB Connector Manager" in the Universal Serial Bus controllers tree. If the dongle is connecting via USB 3.x and it still doesn't work, it could mean that Alternate Mode on a whole is f#$%ed. You may need to re-install the Intel Thunderbolt driver. This might be a stupid suggestion, but can you try rebooting with the dongle still plugged in? or plugging in the dongle when the machine is off and then powering it on? Also, is the dongle connecting via thunderbolt or USB 3.x? The reason i'm asking this is because Thunderbolt itself is an alternate mode on USB-C, which means if your dongle is using Thunderbolt, it could mean Thunderbolt itself isn't working, you can try verify this by plugging in another Thunderbolt accessory and see if it works.
