4k resolution not available at Intel NUC6i5SYH

Hi,

I have recently connected my Intel NUC (board NUC6i5SYB) to a 4K Samsung TV over the DisplayPort (connected to an HDMI port at the TV end). The NUC is also connected over HDMI to an A/V receiver that only supports FHD.

The display driver is from September 2020, the OS is Windows 10 64 bit.

In the display settings, FHD 1920 x 1080 is the maximum resolution for the Samsung TV. I get the same maximum resolution at the Intel Graphics Settings too.

When checking the product data (NUC6i5SYB_NUC6i3SYB_TechProdSpec.pdf), it is stated that the board supports 4K resolutions.

Could you please advise me how to configure the 4K resolution for the Samsung TV?

Thanks in advance!

Regards,

Akis

Hello Akis, 

 

Thank you for posting on the Intel® communities.   

 

In order to better assist you, please provide the following: 

 

1. Run the Intel® System Support Utility (Intel® SSU) and attach the report generated:   

  • Open the application, check the "Everything" box, and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View".    
  • Click on the menu where it says "Summary" to change to "Detailed View".    
  • To save your scan, click on "Next", then "Save".    
  • Use the option under the reply window to attach the report to the thread (Drag and drop here or browse files to attach).   

 

2. Provide the Report for Intel® Graphics Drivers, follow this link.  

3. Just to confirm, are you using an A/V receiver in the original connection? Please include the brand and model number of it. 

4. Please specify these details from your connection: 

  • Full model number of the TV. 
  • Are you using a straight connection from the NUC to the TV or are you using an adapter?  
  • Provide brand and model of the cables and adapters (if any).  

 

Regards,

I am using an SY NUC as a HTPC connected via mDP-to-HDMI 4K@60Hz adapter to a 4K (6000 Series) Samsung TV - and it is indeed connecting 4K@60Hz. I believe that the problem you are seeing is the result of the connection to the other device.

The first thing I would check is connecting to only this 4K TV. Depending upon the capabilities of your connection (cable or adapter+cable), you should be able to run it in a 4K resolution. This is a basic verification step only, however.

The next thing to look at, with both items connected, is the settings in windows. If you are cloning the display, then both sides will run at the resolution of the least capable of the two interfaces. That is, if one is connect to a 2K monitor and the other is connected to a 4K monitor, both monitors will be run at the 2K resolution. To validate that this is happening, change the configuration so that the two monitors are used independently (i.e. extend the desktop). If configured like this, you should be see each monitor run at their native resolutions.

Hope this helps,

Thanks for your reply!

I will try out the basic verification step i.e. disconnecting the AV Receiver that is not 4K capable.

When using the Extended Desktop configuration, I am still not able to set the 4K resolution at the Samsung TV, the only possible highest option is 1080p, the same at both outputs. 

In my case I am not sure if the mDP-to-HDMI cable that I am using supports 4K@60Hz. I will also test with another cable.

By the way, I am also experiencing another problem relevant to the HDMI output; this is audio related.

My AV receiver is seen by Windows 10 as an audio device (Intel Display Audio).

When the AV receiver output is connected to a projector, then the AV receiver audio device is not available. This behavior started after an Intel Display driver update some time ago.

Is there any way to overcome this problem?

 

Thanks in advance,

Akis

Hi,

thanks for your reply.

 

1-2. Please find attached the System utility report and the Graphics drivers report (including the report for the TV and the AV receiver).

3. The AV receiver is not used between the NUC and the TV. It is connected directly to the NUC HDMI output. The model is LG HB905PA

https://www.lg.com/ca_en/home-theater-systems/lg-HB905PA

4. The TV model is SAMSUNG UE55RU7475UXXC TV

https://www.samsung.com/se/tvs/uhd-4k-tv/ru7475-55-inch-crystal-uhd-smart-tv-ue55ru7475uxxc/

The connection is direct, from NUC Display port to TV HDMI port. I do not unfortunately have any details about the brand and the model of the mDP-HDMI cable.

 

Thanks in advance,

Akis

@Akis,

If you disconnect the AVR, what happens to the TV? Does it support 4K@60Hz then? If it doesn't, then throw that mDP-to-HDMI cable in the trash and get a solution that actually works.

If the TV works as it should and plugging in the AVR causes it to drop capability and/or resolution, then, as I said, this is occurring because you are mirroring the output on both. This results in highest common capability and resolution being used (i.e. that of the AVR).

Hello Akis,  

  

Thank you for your reply. 

 

Based on the reports I realized that your product is discontinued, and due to this NUC being discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help. You may also find the Discontinued Products website helpful to address your request. Thank you for understanding.  

 

You may want to follow the recommendations given by @n_scott_pearson and other community members who can help. 

 

Please keep in mind that this thread will no longer be monitored by Intel.
