Using dual monitor on NUC8i7HVK

Forum members,

 

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.

 

Regards

  1. Refer to paragraph 1.6.2.5, page 22 of Technical Product Specification https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC8i7HVK_TechProdSpec.p... to see details off all posible multiple display configurations.
  2. Please, enter Window settings System > Display and press on Detect on R.H. panel under Multiple displays.

Leon,

 

Thanks for youre quick response. In 1.6.2.5 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.

  1. If each monitor with each cable is working with the correct resolution, I don't think that there is a problem with the cable.
  2. Are you working with bios withe default settings? If not, please try to do this.
  3. Most important, are the Chipset Driver, Management Engine Driver and the Graphic driver updated. If not, you may download and install the latest drivers (install in the same order):

Leon,

 

I am going to try updating the drivers. The third one looks promissing. It refers to problems setting up multiple monitors. Thanks so far.

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 25.20.100.6326 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,

...S

Hello @LPeek​ 

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...

Leon. Installing the 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.

Hi Lex,

  1. I'm very glad that your both monitors works now as expected.
  2. I don't know what is your driver update status. Any way it is always good to have the drivers updated. Using the links from my post above, you probably updated the 4 drivers in your NUC.
  3. In this link you may found all the other drivers for your NUV (first you should choose the Windows 10 64 bit) https://downloadcenter.intel.com/product/126143/Intel-NUC-Kit-NUC8i7HVK
  4. If your bios is not updated yet, here also you may download the latest bios version 0054. I suggest to download the HN0054.bio file and update bios by pressing F7 during boot: https://www.intel.com/content/www/us/en/support/articles/000005850/mini-pcs.html
