I am using a Intel NUC8i7HVK under Windows 10 Pro 64bits. Are there any specific requirements for connecting 2 monitors? E.g. 2 connected to each HDMI or 2 connected to each Mini Displayport or a combination of HDMI and Mini Displayport. Cannot get it to work. On each combination only one is working and no detection of the 2nd monitor. Hope to hear.
Thanks for youre quick response. In 184.108.40.206 it is stated that any combination of HDMI and/or Mini Displayport is allowed for dual monitor. If in Windows Settings I try the autodetect, no 2nd screen is detected. See attachment (Sorry, in Dutch).
Does cable certification matters? I an stuck sofar.
The HV NUC has been validated with six independent monitors connected (2x HDMI, 2x mDP and 2x USB-C (DP)), so there should be nothing that would stop you from also doing the same (or some subset).
In my own testing, while I do have three monitors connected to my HV NUC, I had never used the front and rear panel HDMI ports simultaneously (because I *hate* having non-temporary wiring connected to the front panel; it just gets in my way!). I knew that the front panel HDMI port worked, because I tested every port when I first received the NUC, but I essentially ignored it after that.
To repeat your test, I switched over to a USB-C port for my primary monitor. [Aside: Just so I could test a bunch of USB-C-to-HDMI dongles at the same time - and, BTW, found that one dongle, which I had successfully used previously to connect a 4K@60Hz monitor to BE, BN and DN NUCs, wouldn't work with a downstream HDMI-to-DVI dongle connected to it.]. I then switched over to using the front and rear HDMI ports for my secondary monitors. Other than the issue with the USB-C-to-HDMI dongle, I had no unexpected issues using all monitors in Windows. I had to adjust the ordering, based upon where the various monitors sit, but that's to be expected.
BTW, I currently have HN BIOS 53 installed. I am still running the older Intel HD Graphics 220.127.116.1126 and AMD HD Graphics 24.20.11026.2001. I will endeavor to repeat the test with the latest available BIOS and drivers shortly.
Hope this helps,
Reading the Scott's post above remains that ind addition to the driver I've suggested to update, you should update the Radeon Driver as well (it is driver for the AMD chip): https://downloadcenter.intel.com/download/28600/Radeon-RX-Vega-M-Graphics-Driver-for-Windows-10-64-b...
did solve the problem! During installation the 2nd screen already 'poped up'. Thanks for the suggestions. Regards Lex from the Netherlands.
