Connector type is showing DisplayPort instead of HDMI and refresh rate options are limited.

I have this problem since I bought the monitor last July. The monitor supports up to 144hz using HDMI, which I tested on my pc and my brother's. I'm wondering why it is showing DisplayPort connection type instead of HDMI and my I can't set the resolution higher than 60hz. I tried using CRU(Custom Resolution Utility) and found out that I can manually set the refresh rate as long as the pixel clock doesn't exceed 297mhz, which is HDMI 1.4 speed.

My guess is that intel driver is not properly detecting HDMI 2.0 connection so I tried using linux and everything is working as intended there 1440p 144hz and all.

Is this a common issue with Intel Iris Xe? Is there a known fix to this?

Hello wyett,


Thank you for posting on the Intel️® communities.  


To have a better understanding of your issue, please provide me with the following:

  • Does the issue happen on both systems (yours and your brother's)?
  • What is the model of the affected systems?
  • Are you using a straight connection?
  • Have you tried using other HDMI cables?
  • Create a report using the Intel® Graphics Command Center:
    • Open the Intel Graphics Command Center
    • Navigate to the Support tab
    • Select System Diagnostic
    • Click Generate Report
    • Select Save and name the output file.


For this issue, I would recommend a clean installation of the graphics driver 31.0.101.3413. Remember that there are two different types of drivers, generics provided by Intel and Equipment Manufacturer drivers, that are customized to work with each specific system. The best thing to do is to use the drivers provided by the system manufacturer (OEM). Intel’s generic graphics drivers are intended for testing, and we recommend using drivers from the system manufacturer (OEM). To perform the clean installation, follow these instructions:



1. Download the latest DCH drivers and save them on the computer: https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html

2. Disconnect from the Internet so no new drivers are automatically installed by Windows Update. 

3. Uninstall the driver and the Intel Graphics Command Center and driver from Apps and Features. 

4. Restart the computer. 

5. Confirm in Device Manager > Video Adapters that the controller is listed as 'Microsoft Basic Display Adapter' > if not, repeat steps 2 through 4. 

6. If the adapter continues to be listed as ‘Intel HD Graphics’ or similar, and no other Intel Graphics driver is listed under 'Apps and Features' for removal, then it means Windows has switched to a previously installed Legacy driver. At this point we can remove Legacy drivers from Device Manager: 

1. Right-click on 'Intel HD Graphics' or similar, and select 'Uninstall Device' 

2. In the pop-up window make sure 'Delete the driver software for this device' is checked. 

3. Click on 'Uninstall'. 

4. Restart. (Repeat steps 6.1.1 through 6.1.4 until the device gets listed as 'Microsoft Basic Display Adapter') 

7. Install the DCH drivers that were downloaded in step 1 Restart the computer. 


Reconnect to the Internet.

Thanks for the reply. Sorry I was only able to reply now as I was on a trip.

 

I tried and completed all the steps, but the problem still persists. I also tried using the drivers downloaded from the lenovo website but that didn't help. I just ordered a recovery media from lenovo and will try it today. I will keep you posted if the recovery media will fix the problem.

 

Thanks!
