NUC9i9QNX UHD 630 + Tiled Display Topology Support

[ThomasWan]

Is Tiled Display Topology supported on the NUC9i9QNX's two Thunderbolt 3 ports carrying DisplayPort?

We would like to drive two identical DisplayPort displays having different DisplayID configured for one of two tiles in a Tiled Display Topology. We can do it using an external PCIe graphics card but would like to know if the integrated UHD 630 graphics can be configured to support it.

Hello @ThomasWan

Thank you for posting on the Intel® communities.

Please allow us to review this inquiry further and we will be posting back in the thread as soon as more details are available or in case additional information from your environment is required.

Hi @ThomasWan 

I don't believe we support Tiled Display Topology but I am not an expert in Graphics and we could have a similar feature with a different name.

Allow me a couple of extra days to check with the Graphics Team and I will get back to you.

Hi @ThomasWan 

I just got confirmation from the Graphics Team that Tiled Display Topology is supported.

Just to make sure that we are on the same page, lets use this video as reference LG UltraWide Monitor Split Screen & Dual Controller Functionality - YouTube and go to minute 3:57 when PNP is activated, this is what our graphics engine provide support for.

Hi @Ronny_G_Intel 

Thank you for the info. Yes, we are on the same page - two functionally separate DisplayPort links and displays driven from one GPU with two DisplayPort sources and configured as one ultra-wide display using Tiled Display Topology settings to be refreshed synchronously as one by GPU & Windows.

In the case of the referenced LG UltraWide Monitor, the two halves of the display panel can be driven by independent video sources or be configured as one ultra-wide display (which I presume is still driven from two physical display links when configured as one monitor using Tiled Display Topology).

As mentioned, our displays and DisplayPort sinks with Tiled Display Topology settings are working for creating an ultra-wide display in Windows using an external PCIe graphics card plugged into the NUC9i9QNX. We think our EDID/DisplayID for Tiled Display Topology settings is correct. When the same dual displays configuration are connected into the Thunderbolt 3 ports carrying DisplayPorts on the NUC9i9QNX, we see two separate displays in Windows instead of one ultra-wide display. We would like to not require using an external graphics card in the NUC9i9QNX for our application.

Is there a recommended Intel UHD graphics driver for the NUC9i9QNX to work with displays with Tiled Display Topology settings? I have just tried driver 30.0.14.7141 but still do not see the auto configuration of a ultra-wide display with the above configuration.

Thank you for your help and the Graphics Team's help.

Regards,

Thomas

Hello ThomasWan

Thank you for your response.

In regards to your inquiry, we recommend the Intel® Graphics DCH Driver for Intel® NUC, Version: 27.20.100.9415 (Latest).

If the behavior persists, please provide details about the outcome/behavior and run the Intel® System Support Utility (Intel® SSU) to gather more details about the system. Please follow these steps:

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.
• Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

Hello ThomasWan

We are checking this thread and we would like to know if you need further assistance. Were you able to test the Intel® Graphics DCH Driver for Intel® NUC, Version: 27.20.100.9415 (Latest)?

Please do not hesitate to contact us back if you have additional inquiries.

Hi @AndrewG_Intel 

I did test the latest Intel Graphics Driver for NUC (version: 27.20.100.9415) as well as updated BIOS for NUC9i9QNX to latest (version: 0063) but am still unable to have the two DisplayPort sinks be configured as one ultra-wide display automatically with Tiled Display Topology.

I will revisit early next week to run the System Support Utility to output the text file.

Thank you for your continued support.

Best Regards,

Thomas
