Problème affichage 3 écrans ARC A770

[hugo_hgs]

Bonjour depuis maintenant une semaine ma carte graphique Intel arc a770 ne détecte plus mon 3ème écrans au démarrage. 

Je suis obligé de débrancher et de rebrancher sur un autre port display port. 

J'ai déjà réinstaller les drivers, supprimer les anciens, changer les câbles, changer les écrans.

Est-ce possible d'avoir une solution fonctionnel cette fois-ci ?

Merci d'avance pour le retour.

Hello hugo_hgs

Veuillez noter que je ne peux vous aider qu'en anglais. J'ai utilisé un outil de traduction Web pour traduire cette réponse. Il se peut donc qu'il y ait une traduction inexacte.

Thank you for posting on the Intel® ARC™ Graphics Communities. I understand that the 3rd display on your setup is no longer being recognized and I know that having to disconnect and reconnect the cable every time for the display to come up is inconvenient.

In order to help with this issue, I would like to get a better sense and more information about how your system is set up , we will need the following reports that will have the monitor information as well as the hardware information:

Report for Intel® Graphics Drivers( Only Intel Graphics Command Center Intel GCC)

Intel® System Support Utility

In addition to the above information to discard possible compatibility issues, please let us know if you are using any type of video adapter or direct connection as well as if this issue only happens with a specific monitor or with any monitor that you configure as your 3rd display.

Best Regards,

Hello no this happens with all kinds of hardware with any brand. Here are the reports:

Hello hugo_hgs

Thank you for sharing the information. I understand that this issue happens regardless of the monitor as long as it is configured as the third display it will not show anything until the cable is disconnected and connected back to the display. This might mean this is not a monitor issue. As for the cables please let us know if you are using video adapters/dongles and as well if you have tested different cables.

From the log files that you shared with us, I see that your BIOS is the first one released for your motherboard since then there are been updates to improve GPU compatibility and OS compatibility so please visit your manufacturer's website and update the BIOS to the latest version. From what I see the latest version should be 7D09v19. From the software side, I would also suggest that you do a reinstallation of the 31.0.101.4644 driver or you can use the latest release 31.0.101.4669 but this time use Display Driver Uninstaller to uninstall previous versions.

In case the issue continues, I would like to know whether this configuration was working fine for you before, and if so, what was the driver you were using? Is the issue not happening if you roll back to that driver? This is important to know if there might be a problem going on with the driver update. In addition, please let me know if you are using an extended display configuration.

it doesn't change anything, I also just saw that the drivers can't update the HDMI firmware even though a cable and a screen are plugged into it

Your graphic card vbios seem, already, updated : I think 20.1064 is the latest one for the arc 770.

Hello hugo_hgs

As noted by @Omëron the firmware on your GPU seems already updated, f you had any error I would advise reinstalling the driver using only one HDMI monitor. I see the issue persists after updating your BIOS and using Display Driver Uninstaller to update to the latest version. We are still missing some important information we requested in our previous posts:

• Are you using any type of video adapters or are the connections native?
• Have you tried using different cables?
• Was this 3-monitor configuration working fine before? If so, What was the driver version you were using?
•  Is the issue not happening if you roll back to that driver?
• Are you using an extended display configuration?

Sorry for the late response, yes everything has been tried:
other screen
other cable
one screen at a time nothing allows updating the HDMI firmware, I can't even go beyond 60hz...

Hello hugo_hgs

Thank you for the information. There is a newer driver update version 31.0.101.4672, We would need to do more research on this issue, but we would like you to first update and test the latest driver to check if the issue continues to happen. Perform the installation using Display Driver Uninstaller to make sure there are no errors when updating.

Hello hugo_hgs

I wanted to check if you had the chance to do the driver update as advised in our previous post, but also, I wanted to let you know there is even a newer driver version 31.0.101.4676, so I would suggest dating to this one instead.

Hello hugo_hgs

We hope the last driver updates that we suggested in our previous post helped you resolve this issue and that your monitor now gets recognized at startup. We have not heard back from you so we will no longer monitor this thread but feel free to open a new topic if you need further assistance

Hello hugo_hgs

We are interested in continuing to help you address this issue in case the behavior is still happening after the last driver update we recommended, so far we understand that the display which is configured as a third monitor under Windows does not get recognized upon boot, and that this happens regardless of the monitor connected, correct?

What happens if you only connect the affected display and while the system is on you add the other two and then restart? Can you check if the same happens?

Hello hugo_hgs

Have you had the chance to test our previous post? We wanted to know the behavior if you try to connect only the affected display and then the other 2 one data time while the system is on. We would appreciate your feedback so we can help you resolve this issue.
