Intel Arc stuck at native 1440p output

[Skrobek]

Hello,

I'm using an Intel Arc B580 Limited Edition with a GIGABYTE G32QC monitor (2560x1440 native resolution).

No matter what resolution I set in Windows (e.g., 1920x1080) or in games like CS2 (fullscreen), the GPU always outputs a 2560x1440 signal to the monitor, which affects performance and scaling behavior.

I've updated the monitor firmware and GPU drivers and tried different scaling modes, but the monitor still receives a 1440p signal. When setting a 4:3 resolution like 1280x1024 in CS2 (fullscreen), it still outputs 2560x1440, making it impossible to get proper 4:3 scaling.

Is there any way to force the GPU to output the actual resolution I set in Windows or in-game?

Hello Skrobek,

Thank you for posting in Intel community Forum.

For me to further check this, please help provide the following details:

1. When did you start having this issue?
2. Was it working fine before?
3. What was the last change in the system before the issue started?
4. Are you using an Intel brand Arc B580?
5. Do you have other app or program that can also change the display settings that may having conflict with the setting that you are changing?

If you have questions, please let us know. Thank you.

Best regards,

Hello,

Thank you for your response. Please find my answers to your questions below:
1. I started having this issue as soon as I connected my computer to my current monitor (GIGABYTE G32QC). I strongly believe the issue is related to the monitor, because when I tested the same computer (with the same settings and GPU) on a different monitor, everything worked correctly.
2. Yes, it worked fine when I tested it on a different monitor at my friend’s place — I didn’t change anything in the system, and the resolution was applied correctly.
3. I didn’t make any system changes before the issue started — it occurred immediately after connecting the G32QC monitor.
4. Yes, I’m using the Intel Arc B580 Limited Edition (Intel brand).
5. No, I only use Intel Graphics Software. I don’t have any other apps that could interfere with display settings.

Let me know if you need additional information or logs. I’ll be happy to assist further.

Best regards,
Alan

Please set the desired resolution in the Windows display settings. Then open the Intel Graphics Software and set the Scaling Mode to Display Scaling. If this mode is already set, change it to one of the other available options and then back to Display Scaling. The change should then take effect in the active signal mode.

Hello Skrobek,

I hope this message finds you well. 

Were you able to check the previous post?

Hello Michael,

Apologies for the delayed response.

I’ve tried everything, including the suggestions from the other forum user, but unfortunately, nothing resolved the issue. I eventually had to give up and returned the graphics card.

After switching to a different GPU, the problem no longer occurs. I’m still not entirely sure what caused it, but it might have been related to Intel’s drivers.

Thank you for your assistance and support throughout the process.

Best regards,
Alan

Hello Skrobek,

Thank you for the update and I am sorry to hear that.

I was about to gather more details to further investigate the cause of the issue.

Since you already returned the unit, I need to close this inquiry. 

If you need further assistance, please post a new question as this thread will no longer be monitored. 

Thank you and have a great day. 

Best regards,

Can I reactivate this huge problem?

An investigation revealed that several people have been affected, and Intel must be aware of this.

For the time being I won't resend my new AsRock Intel ARC B570 graphic card.

I have received this device 2 days ago on Wednesday 6th May.

I am using Windows 10  64bit 22H2 / MSI B450 Gaming Plus Max motherboard socket AM4 (MS-7B86) / AMD Ryzen 7 2700x processor (8 core).

Problem:
I am stuck at 4K (3840 x 2160) resolution whatever I do.
For HTPC (Kodi, MPC player, ...)  it is important also lower resolutions can be delivered such as 720p or 1080p resolution.

Tried so far: 

• different screens:  Samsung LE32C530 (old HD LCD) + TCL 75C9K  (2025 4K mini LCD)
• different HDMI inputs
• HDMI output + Displayport output (i.c.w. adapter to HDMI)
• diffrent HDMI cables
• different settings in Intel IGS  >>> IGS crashes several times !!!

Observations:

In the advanced display settings window the desktop resolution and the active signal resolution are always different.

When changing the resolution, the desktop resolution is indeed changed, but the active signal resolution stays always on 3840 x 2160.
No changes visual on the real screen (TCL or Samsung) !!!

This is what I also found by searching:

"Intel Arc GPUs may show only the native resolution or fail to scale lower resolutions, forcing the desktop/games to run at maximum resolution (e.g., 4K) despite settings changes. This occurs because Arc sometimes locks the active signal resolution to the native EDID, requiring users to set lower resolutions via advanced settings or using third-party tools.

So an EDID locking problem. Through the Intel graphic (bad) driver probably."

I have used in my life many Graphic cards from Nvidia or ATI / AMD, but never ever encountered this problem.
So I whish some solution can be found. Preferably by Intel. If not from third-party tools.

Thanks

Yes, the EDID data of the display device does influence the driver's behavior. While I wouldn't rule out the possibility that the driver itself contains a bug, it is certainly possible to modify the EDID data so that the driver behaves exactly as required.

Please connect the display device that needs to be analyzed, generate a System Support Utility Log, and attach the output file here. We can then analyze it.

[krisnkras]

Thank you for the confirmation.

I did what you asked and can find the resulting file in attachment.

[krisnkras]

Something went wrong.
Here is a link to the file.

I have spent some time experimenting with the EDID of the TCL 75C9K, but unfortunately, the behavior described remains unchanged.

The only thing that helps is that, after changing the resolution, you briefly switch the display scaling in the Intel Graphics Software to "GPU Scaling" and then back to "Display Scaling." This ensures that the Active Signal Mode then matches the Desktop Mode.

This is acceptable for a work PC, but hardly suitable for a media center that aims to automatically adjust the resolution to match the movie as soon as it starts playing.

@IntelSupport : Could the graphics driver team please take a look at this?

[krisnkras]

Thank you for taking the time to look into this.
