Latest Drivers causing DisplayPort issues

[Basyll]

Hey,

Ever since the driver version 4644 came out for my Intel ARC770LE it caused my displayport to be permanently stuck at a refresh rate of 60Hz. Whenever I go into the windows display settings, the refresh rate no more lists multiple options and thus it's set at a default 60Hz while my monitor supports up to 144Hz.

I've never had any display issues with all the drivers before version 4644 as I was able to set my refresh rate to 144Hz. Unfortunately, the latest driver update simply doesn't allow that anymore, and I'm 100% confident the underlying cause of this issue is the fact that driver version 4644 came with an HDMI firmware update, and that firmware update definitely messed things up for people using a DP connector. I hope this issue is fixed asap on the company's side.

I've tried completely uninstalling the latest drivers and going back to driver version 4577 which, as expected, fixed the issue. But why would I limit myself being stuck on an older driver that's less optimized in comparison to the newer versions? I'd love to make use of the new drivers without encountering these unnecessary display issues.

By now, I've updated my graphics driver to an even newer version 4669, hoping it would've perhaps resolved the issue but alas. I then experimented a little and disconnected my DP connector and instead plugged a regular HDMI connector into my GPU and monitor and voila, my refresh rate is back to 144Hz, and so the issue seems to be magically fixed. Am I satisfied with this solution though? Absolutely not. Albeit temporary, I still prefer using my DP cable and it's a real bummer that because of the HDMI firmware update included with the latest drivers that it unables me to keep using my DP connector. I hope this issue can be forwarded further to the development team over at Intel Graphics.

Hello Basyll,

Thank you for posting in the Intel communities and reporting that you are experiencing issues setting the refresh rate when using a DisplayPort connection. We would be more than happy to help you.

For testing purposes, we recommend you eliminate all driver residues and leftovers using the Display Driver Uninstaller and install the latest Intel driver, 31.0.101.4669. Check How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver for instructions.

However, if the issue remains, we would like to have further information about your system to look into this problem internally, so please provide us with the following reports:

• Intel System Support Utility (Intel SSU)
  • Open the application and click "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 it to "Detailed View."
  • To save your scan, click "Next"; and then "Save."
• 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.

It was a DP issue two weeks ago when I updated the driver,  I have to roll back the dirver to support my 2K display, and the  old driver continuously warned me that it failed to roll back the firmware  ,   now the DP is completely dead, card was sent back to reseller.

I'll report back later this week. Quite busy right now.

As for your DDU suggestion, I've already tried that ... The results are still the same. I'll handle over the reports when I've got time.

See ya.

I suppose you misread me.  I sent the card back for a replacement.  I got a new card, I decided to stay on the good old driver as long as I can. I can not afford to break DP of the card again, the whole process is too 'energy' consuming.

Hello Basyll,

Before we close the thread, we want to let you know that we would like to further investigate this issue, but we require more information, especially:

• Install the latest driver 31.0.101.4824. Connect the monitor via DP, and let us know the outcome.
• Run the Intel Graphics Command Center and create a system report so we can investigate EDID info.
• Run DxDiag and send us the report to investigate OS-Display data.
