philips 222v8

[boombastik]

I bought a new b570 card.

With my old NVIDIA rtx3050 card and monitor philips 222v8 i could enable in control panel that my monitor is g sync compatible, with display port.

The monitor supports adaptive v-sync.

With the b570 intel i cant enable the vrr support.

My monitor is 75hz and i connect with display port.

Philips lists only AMD graphics cards as compatible in the user manual for the 222V8 monitor (see section 4 "Adaptive Sync"). However, if an Nvidia card supports variable refresh rates via DisplayPort, this should also be possible with an Intel Arc B570.

Please run edid-test.exe:

This will create a file named "edid-test.txt" in the same folder. Please attach this TXT file here.

Here i attached the file.

The data shows that the monitor supports both VESA AdaptiveSync and AMD FreeSync in the 48–75 Hz frequency range.

Can this be enabled in the Intel Graphics Software?

[boombastik]

In this display menu and general section i see only scaling mode and scaling method.

The variable refresh rate section does not exist.

In the last section that says information  it says that variable refresh rate does not supported.

Your driver version 32.0.101.8247 is up to date. This DisplayPort to DisplayPort connection is usually foolproof. I don't understand this either.

We need advice from the Intel Graphics Team. Is there a driver/compatibility issue here?

[boombastik]

The same problem with the whql driver

Monitor Hardware ID: Monitor\PHLC251

Can anyone please answer?

I have connected this with display port.

[boombastik]

My device id for monitor is PHLC251

If i use cru and change the id to DELA179

The vrr works as intended.

You seem to don't correctly identify the Philips monitor or you have hardcoded the ids in the driver.

Oh, that's very interesting.

Before:

After:

The device ID was originally read into the Windows registry by the Nvidia card. This could have led to an unintended incompatibility after the graphics card change. I've never seen anything like this before.

It would be interesting to see what happens if you run the "reset-all.exe" file from the CRU download package. This resets all ever created EDIDs in the Windows registry, and after restarting the computer, only the actually connected devices will be recognized. I'm almost certain the monitor would then work correctly again with its original device ID.

How did you uninstall the Nvidia driver? For a graphics card change, using Display Driver Uninstaller (DDU) is recommended.

[boombastik]

I uninstalled the nvidia driver with ddu.

When i run the reset-all.exe ,at restart the vrr is not supported.

I also uninstalled the intel driver with ddu and reinstalled.

Now when i re-edit the id to DELA179 it works again.

It seems that is an easy fix to add support for Philips with PHLC251 id.

[MUC]

Thanks for your feedback. That's really interesting.

The Intel Graphics Team should definitely take a closer look at this. Very strange.

I created a thread there in igcit for the workaround and this is the answer:

Totally disappointed and i  was a beta tester for big companies.
