Intel Arc A770 16G no native resolution on 2560x1080 Display with Driver newer 4578

[mex3456]

Hello Intel and Community!

I have a problem with ALL Intel Arc drivers newer tha 4578.

I have an Intel i5 13600KF on an ASRock Z790 with 32G Ram, Windows 11 Pro on Crucial NVME SSD with an Intel Arc A770 16G LE. My Display is an LG 21:9 2560x1080 75Hz.

With all drivers until 4578 it works fine in fullscreen, but only 60Hz. Thats fine for me, because the Arc isn't powerful enough for much higher resolution.

Since then with EVERY newer driver i'm stuck with 1920x1080 60Hz as the highest possible resolution in Windows, the Arc Control Center and every Game or App i start.

I've contacted the Intel Support and uploaded the some Logs and they told me the standard phrases like update your Bios, use the newest drivers and so on. I told them that native resolution and fullscreen IS possible until driver 4578 and that it has to be a bug in the newer drivers. Then they refused to do any research and closed the case, because i didn't want to do a bios update.

So i need help, because i'm stuck with an old driver and want do destroy this piece of trash, because they don't take me seriously.

Pls Help, mex3456

It's definitely a driver issue - there are numerous threads that need the dots connected by intel due to the symptoms being different.  I am suffering the same regression since the same driver - disappointingly I don't see Intel posting it as a known issue in the driver releases (I lost count but I think we are 4-5 driver releases in since its been reported).

For me HDMI was working but none of the display ports.   
From the numerous threads the common denominator  seems to be that its failing on 21:9 Ultra Wide Displays as I can see people reporting it with different brands of intel and different brands of monitor (albeit LG seems to be the most common).

I'm hoping this feedback to intel dev's will help in tracking down the issue - as it seems to me that the latest driver(s) seem to stop the board detecting the monitor correctly and therefore defaulting to a fairly safe, smaller resolution.

When I have chance I'll draw up a list of all the threads which I think are related as I'm counting at least 12 having reporting this issue for quite some time.   This seems to be the most active ...

My 1440p monitor can only output at 1080p resolution now · Issue #433 · IGCIT/Intel-GPU-Community-Issue-Tracker-IGCIT (github.com)

I'm shocked that they closed the ticket, and they should have been able to look at the issue description and the fact that it works on an earlier driver as evidence enough.   However, I understand the protocol in ensuring the latest bios is on the mainboard as this could affect other issues, sometimes though you need to read between the lines when supporting end users.   

Intel, can we have this documented on the Known issues please, as people are going out spending on the new cables when it is not necessary - at least have them test on the 101.4577 driver in your testing phase.    (You might want to put that back on the website until this issue is resolved as it was removed recently).

Many thanks

what bios version are u at?

on new boards like this you really should keep updated.

probably wont fix your issue,   but its silly to not update your bios. tons of stability improvements

Hello mex3456,

Thank you for posting on the Intel®️ communities. I know how frustrating is not to be able to use the monitor native resolution, I will be more than happy to help you.  

To have a better understanding of the situation, please answer the following questions:

• What port are you using to connect the monitor?
• I see you mentioned your display is an LG 21:9 2560x1080 75Hz. Can you provide me with the model?
• To know your system configuration download and attach the report for the following tool Intel® System Support Utility for Windows (SSU), you can find the steps on the link How to get the Intel® System Support Utility Logs on Windows.

Hello Andres,

the display is connected via DisplayPort Cable.

The model is an LG 29UB67-B and it only works at 60Hz with the Intel Arc. Thats not a huge problem, but it's not how an Arc should perform!

I have attached the result

Hello mex3456,

Thank you for your response, and all the information provided.

I check in the Intel® SSU that your BIOS and the graphics driver is not upadated, please follow the steps below and let me know the results:

• I understand the issue is present in driver newer than 4578, but lets see if the behavior changes after clean installing it to version 31.0.101.4826 with Display Driver Uninstaller (DDU). For guidance, How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver.
• Update BIOS to the latest version 9.07. For installation steps contact ASRock.

I told you, that the newer drivers don't work and so i can't use and work with them! It's my only PC and i need it to work. It's not the testing PC for Intels bad programming. Fix your bad coding in your newer driver, i don't have time for testing out and installing back and forth. I'm not an idiot and it works with the older ones, so it has to be a problem with programming. Or close the case and ignore it, like before. I think Intel Arc is Sh*t since the newer drivers, and i have to replace it...

Hello mex3456,

I understand your frustration and also understand that you do not have time for testing, I want to let you know that we are working really hard on this issue to fix it as soon as possible, but these tests, information, and files requested will help us with the investigation and to find a solution.

As mentioned before I am aware that you do not have the time to complete them, but if you will have it later and you still want to have this thread open just let me know and I will be more than glad to help you.

@mex3456 

Can you give a try with the latest version (101.4885)

I have reports from other cases similar to yours claiming its working on that version.

hope is not to late

[mex3456]

Dear Arturo, thank you for your message. It is working on my system! Thank you!

And it is working without any Bios update or other bullsh*t. So it was something with the driver and the coding, as I suspected from the beginning.

[Andres_Intel]

Hello mex3456,

Thank you for your response, and for keeping us informed.

Happy to hear that the issue is fixed by installing the graphics driver 101.4885. For now, we will close this thread. If you need any additional information, please submit a new question as this thread will no longer be monitored.

Help me please !
I have the same problem, I tested with several driver versions, but without success.

[mex3456]

Do you have any older driver who is working properly? If so the only thing you can do is install the next, see if it works, if not roll back and try the next one. Intel isn't helping at all. I only installed the display driver and kept the control center and always went for the clean install. For me it worked with driver 4885 and until 5186, than i replaced it with an nvidia rtx...

Good luck mate

I think you must be hitting another issue - as this has been resolved (at least for me).   

If your monitor is not hitting the correct resolution, then I would first check the cable - ensure it is of suitable quality, I've been through a few cheap ones which cannot sustain the data transfer required and will either cause flashing or lower resolutions being offered.

.... Best of luck.
