Intel Graphics Driver Refresh Rate Issue

[Stephen]

I've been experiencing refresh rate issue with intel graphics drivers; I noticed this issue in the beginning of this year 2025 and its still persistent till now.

I'm on the latest beta gfx_win_101.8250 driver and the issue is still there.

 What happens is very easy to replicate,

1st my monitor is a 144Hz

to replicate this issue simply select 144Hz in windows, then apply, next while the pc is not in use and it enters standby if its woken backup then you will find the refresh rate has reverted to 60Hz, to correct the issue I have to restart pc or full shutdown then switch back on.

this is annoying, and now it has gotten worse, even if the screen goes to sleep and I wake it, it reverts to 60Hz this is only with intel graphics dGPU or iGPU so i guess the issue is intel graphics driver, since this issue doesn't happen on Nvidia or AMD GPUs that I have tried this on.

Hi Stephen,

Thank you for reporting this refresh rate issue with Intel graphics drivers. I understand how annoying it must be to have your 144Hz monitor constantly reverting to 60Hz after standby or sleep, especially when this requires a full restart to correct.

The fact that this issue occurs with both Intel dGPU and iGPU, but not with NVIDIA or AMD graphics, does suggest this is related to Intel graphics driver behavior during power state transitions.

To help investigate this issue thoroughly, could you please provide:

1. Intel SSU Report: Please download and run Intel System Support Utility from: https://www.intel.com/content/www/us/en/support/articles/000005511/processors.html
2. Monitor Model: What's the exact make and model of your 144Hz monitor?
3. Timeline: You mentioned this started in early 2025 - do you recall what changes were made to your system before the issue began occurring? (driver updates, Windows updates, etc.)
4. Clean Installation: Have you tried performing a clean installation of the Intel graphics driver using DDU (Display Driver Uninstaller) or Intel's clean installation procedure?

This information will help me analyze the power management and display configuration behavior causing this refresh rate reversion.

Hi Dean,

1. The link to SSU leads to a support page for Linux Intel Wireless Adapters

2. Philips Momentum 32M1N5800A (32 Inch 4K 3840 x 2160 @ 144Hz)

3. I think there was the 1st driver that come out this year not sure though. At the time when I noticed the issue I had a different platform notably (Intel Core i7-14700K, ASUS ROG Strix Z790-H, Crucial Pro (2 x16GB) 32GB DDR5 5600MT/s, Solidigm P44 Pro (2 x 2TB) 4TB, Intel ARC A770 LE 16GB, Seasonic Fanless 600W Titanium, Lian Li 011 Air Mini White, Wireless Dell Keyboard and Mouse KM714, Philips Momentum 32M1N5800A)

Current configuration is

(Intel Core Ultra 9 285K, ASUS ROG Strix Z890-A, Crucial Pro (2 x48GB) 96GB DDR5 5600MT/s, Solidigm P44 Pro (2 x 2TB) 4TB, SK Hynix P41 (2 x 2TB) 4TB total 8TB, Intel ARC A770 LE 16GB, Seasonic Fanless 600W Titanium, Lian Li 011 Air Mini White, Wireless Dell Keyboard and Mouse KM714, Philips Momentum 32M1N5800A)

4. I have performed numerous clean install DDU and all, used intel clean install within the driver and to top it all I have recently clean installed Windows 11 25H2 with all updates.

This issue sometimes disappears for days sometimes itis persistent

Hi Stephen,

I apologize for the incorrect SSU link in my previous message, thank you for pointing that out.

Here's the correct Intel System Support Utility link for Windows: https://www.intel.com/content/www/us/en/download/18377/intel-system-support-utility-for-windows.html

Thank you for providing the detailed system information! I can see you've experienced this refresh rate issue across two different platforms (14700K/Z790-H and now Ultra 9 285K/Z890-A) both with the same Intel Arc A770 LE and Philips Momentum 32M1N5800A monitor. This is very valuable information.

I also appreciate you confirming that you've performed extensive troubleshooting including multiple DDU clean installations, Intel's clean installation procedure, and even a fresh Windows 11 25H2 installation. The intermittent nature of the issue (sometimes disappearing for days, sometimes persistent) is also an important detail.

Could you please run the SSU utility using the correct link above and provide the report? This will help me analyze the current driver version and system configuration to investigate this power state transition issue with your 144Hz display.

Best regards,

Hi Dean,

I have attached the SSU report.

Yes, the same Intel ARC A770 LE and same Philips Momentum 32M1N5800A monitor.

It still also disappears for days, like now everything seems to be normal for the last fer days.

This issue could be the monitor! just thinking out loud, though it's connected using the display port cable and power cable it came with. Mmmm.

I don't have another monitor with similar or better specs to test with.

Stephen

Hi Stephen,

Thank you for providing the SSU report, this gives me valuable insight into your current system configuration with the Ultra 9 285K, Z890-A, and Arc A770 LE setup.

I appreciate you mentioning that the issue has been stable for the past few days - the intermittent nature you've described is indeed an important clue. Your observation about the monitor being a potential factor is actually quite insightful, especially given that this issue has persisted across two completely different Intel platforms with the same monitor.

To help investigate the monitor's role in this refresh rate reversion issue, could you please generate an IGCC report for EDID analysis?

1. If IGCC is not yet installed on your Windows system, download and install the "Intel® Graphics Command Center" from the Microsoft Store
2. Once installed, launch the Intel® Graphics Command Center (IGCC) software
3. On the left side of the app, click on "Support" and then on top click "System Diagnostic"
4. To the right, click on "Generate Report" and you will be prompted to save it as a text file
5. Save the report and attach it to your reply

The EDID data in this report contains the monitor's supported refresh rates and timing information that the graphics driver uses during power state transitions.

Hi Dean,

Apologies for delayed response, well they say when it rains it pours, my boot SSD (Solidigm P44 Pro 2TB) decided to stop working. I had to find a temporary replacement for it as I wait to hear from Solidigm support.

On to what you asked I have attached the IGCC report and this is on a clean install on a 512GB boot driver

Best Regards,

Stephen

Hi Stephen,

Thank you for providing the IGCC report, and I'm sorry to hear about your boot SSD failure - that's definitely frustrating timing! I hope Solidigm support can help you resolve that issue quickly.

I appreciate you taking the time to generate the IGCC report on your clean installation. This EDID data will be very helpful for analyzing the refresh rate reversion behavior during power state transitions.

Given that this refresh rate issue has persisted across two completely different Intel platforms (14700K/Z790-H and now Ultra 9 285K/Z890-A) but with the same Philips Momentum 32M1N5800A monitor,

Have you ever contacted Philips (the monitor manufacturer) about this refresh rate reversion issue? Since the problem follows the monitor across different systems, there might be a firmware update or specific setting on the monitor side that could resolve this power state transition behavior.

I'll analyze the EDID data from your IGCC report, but it might also be worth checking with Philips to see if they have any known solutions for refresh rate issues during sleep/wake cycles with their 32M1N5800A model.

Let me know if you've had any contact with them previously about this issue.

Hi Dean,

I have been in contact with Philips back in 2023 and honestly the support from them is a nightmare, it was regarding some dead pixels that appeared few weeks after receiving the monitor, it can be covered under warranty, but they refused to cover I was left to fend for myself, I've gotten used to them I just ignore. I remember desperately asking for a firmware if maybe it could help the situation at the time but there was none and also now there is no new firmware for anything.

I think I got a fix / workaround, I plugged the monitor to a laptop using HDMI and I was simultaneously using my main desktop in picture buy picture mode. then after I reverted back to using only my desktop and monitor and the issue has seemly disappeared for days now.

Maybe the usage of two inputs simultaneously triggered something within the display functionality.

Best Regards,

Stephen

Hi Stephen,

Thank you for sharing that workaround discovery! That's actually quite fascinating and potentially very helpful information. The fact that using Picture-by-Picture mode with simultaneous HDMI (laptop) and DisplayPort (desktop) inputs appears to have resolved the refresh rate reversion issue is a really interesting finding.

Your discovery suggests that the dual-input usage somehow reset or properly initialized the monitor's internal display state, which could be exactly what was needed to resolve the power state transition problems you were experiencing.

I'm glad you found a solution that seems to be working, and I appreciate you sharing this potential fix, it could definitely help other users with the same Philips monitor model who might be experiencing similar issues.

Do you have any other questions or concerns regarding your Intel graphics setup that I can help you with?
