Hello MayMeteonyker,  

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) to gather more details about the system.  

· Download the Intel® SSU and save the application on your computer  https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

· 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.  

2. Provide the Report for Intel® Graphics Drivers:

3. Is this issue recent? if so, did it happen after a system update?

4. Did you update the firmware for your monitor?

5. Did this configuration (4K 60Hz) before? (Ex: Monitor Philips with another computer or same computer with another laptop)

The GTX 1080 has support for DisplayPort 1.4 (while UHD 630 only has DisplayPort 1.2). This means that, even with the loss of half of the channels in a USB-C connection, it is still capable of supporting 4K@60Hz. Bottom line, that's not an apples-to-apples comparison. With DisplayPort 1.2 and USB support in simultaneous use, you are limited to 4K@30Hz.

What do i have to do To be able to run the display at 4K 60Hz

[n_scott_pearson]

Are you connecting the monitor with a USB-C-to-USB-C cable? Does the monitor offer USB port(s)?

If the answer to both questions is yes, then 4K@30Hz is the maximum attainable. Why? Well, (a) you only have support for DisplayPort 1.2 - which means best you can do is 4K@60Hz - and (b) when USB is supported, only 2 of the 4 lanes are available for DisplayPort usage - which means half of 4K@60Hz which is 4K@30Hz.

Hello MayMeteonyker, 

Based on the tests and reports, I would like to inform you that this issue may be related to external factors such as:

- Cable used, try with a display port if possible or another USB-C.

- Motherboard limitation, check with motherboard manufacturer.

- Bandwidth limitation, as n_scott_pearson mentioned.

My recommendation will be to try with different cables and check with the motherboard manufacturer for more steps (driver/BIOS). Also, you may find helpful the following information:
