Processor's Graphics Output Slower than usual.

[waffleRL]

I've noticed that lately my monitor stopped supporting 144Hz due to Pixel Clock maxing out at 297 MHz. It has worked at 350MHz (as advertised) for the last 2 months so I have no clue why that is happening just now... I would like to have 144Hz back, playing at a non-native frequency makes the games look very stuttery in comparison (to me).

Included a SSU report in the attachement.

Hello waffleRL,  

Thank you for posting on the Intel® communities. I am sorry to know that you are having issues with your  Intel® UHD Graphics for 11th Gen Intel® Processors.

In order to better assist you, please provide the following:  

1. Did the issue start after a system update (BIOS, drivers, Windows)?

2. What is the brand and model name of your monitor?

3. Are you using an adapter or a straight connection?

4. To confirm, is this issue present with drivers from MSI?

5. To confirm, did you update the monitor's firmware?

6. Have you checked this issue with MSI?

Regards,

1. I think it has, I've checked the event viewer for some info and exactly when my issue started a driver has been configured/modified, so I assume that is what happened, though after Installing my old drivers (the ones which 144 was present) nothing really happened. There is one thing I missed though, the first time I've installed those drivers my OS was Win10 not 11. I'm considering downgrading to 10 and see if those drivers end up working, but that would erase all my data which I don't really want to do.
2. Don't think it's the monitors fault here but it's a msi G24C4 144Hz monitor
3. No adapters, just HDMI.
4. The ones that worked were the Win10 drivers reccomended by the msi driver center software at the time, the issue started with them installed too (unless the drivers updated themselves which I think is what happened). Now at Intel's latest drivers the issue persists
5. I installed the monitor drivers the day I got it, there hasn't been any updates to them since they came out in 2019 though I'm afraid.
6. Haven't done that yet, but if all else fails (Even the Win10 downgrade) I will eventually do it.

Hello waffleRL, 

Thanks for the information provided. In order to continue further, please try the following:

1. Check with MSI to confirm that you have installed the latest BIOS version (E16R6IMS.10D):

• https://www.msi.com/Laptop/GF63-Thin-11UX/support?sub_product=GF63-Thin-11UD

2. Check with Nvidia to confirm that you have installed the latest drivers on their part.

3. Try to load BIOS settings to default, as a test.

Best regards,

Sadly, none of those solved it. Tried restarting the graphics driver after each step and nothing changed.

Hello waffleRL, 

Thank you for the information provided 

I will proceed to check the issue internally and post back soon with more details.

Backed up all the files, installed Win10 and the old drivers, It did nothing but waste time.

Hello waffleRL, 

Thanks for your patience. In order to continue with the investigation, please provide the following:

1. What is the exact brand and model name of the monitor?

2. Provide the Report for Intel® Graphics Drivers with the monitor connected: 

• https://www.intel.com/content/www/us/en/support/articles/000005848/graphics.html 

3. Where are you seeing the Pixel Clock maxing out at 297 MHz?

4. What is the exact resolution that you want to use with a 144Hz refresh rate?

5. Do you remember what was the update that changes this? what do you mean by driver configured/modified?

6. Are you using a high-speed HDMI cable?

7. Test with the MSI driver 30.0.100.9864

1. msi Optix G24C4

2. Attached

3. I figured it out by brute forcing custom resolutions, the highest one that worked was 131,4 Hz which is ~297 MHz. Going even 1 MHz above that makes it not show up on windows advanced display properties.

4. Same as before, 1920x1080

5. I haven't updated anything that day, but it happened after I came back home with the laptop and plugged everything in like I do everyday. That's what event viewer said, I'll include the event history and the description of the event that caused all this.

6. Yes, a HDMI 2.0 Cable, it's the same cable I've used with the 144 working.

7. Was worth a try, but still no 😕

Hello waffleRL, 

Thanks for the confirmation. I will proceed with the investigation and I will let you know about any updates as soon as I have any details for you.

Hello waffleRL, 

Thanks for your patience. I would like to let you know that since the issue occurs with both drivers (Intel and MSI) I do not think this issue is related to the drivers. Also, it used to work before, so it is not probable that this problem is caused due to a bandwidth issue.

I noticed that the drivers for the monitor (https://www.msi.com/Monitor/Optix-G24C4/support#driver) are Windows 10 supported and you are using Windows 11, just for you to know. In this case, I recommend you the following:

1. Try to check the monitor settings and see if there is an option for the resolution.

2. The best thing to do since you set up is from MSI, would be to check this issue with them since they may need to run some tests on their devices.

I've contacted them, and we have checked that it's 100% not the hardware and It's something within the Windows OS doing it, I installed Ubuntu and 144Hz worked to my surprise, also the Pixel Clock gap - thing was gone and it could run at it's normal speeds. I won't switch to a different OS just to get 24 more Hz but It's got even more annoying now that I know the issue is not up to me or the hardware and I'll have to either wait for an update that removes the cap or find old Windows builds that did not have it.

What if the iGPU is recognizing the monitor as a TV and therefore shows those resolutions? I know you can switch between that and PC resolutions on nVidia control panel but there's none on IGCP
