Re:Intel graphics 630 can't read correct EDID in Windows11

hachu · ‎06-13-2022

Hello,

I have some problems with Intel graphics 630.

OS=windows 11

Driver = newest

Description1

When I plug a VGA cable with A monitor (1920x800), it can't read correct EDID with moninfo.

I have check registry, it seems not correct.

Q1.How can I read correct EDID from EEPROM not registry or how registry can record correct EDID from EEPROM.

Description2

Then I changed the A monitor to B monitor(1920x1080), it still keep to A monitor (1920x800),

status and can't adjust the resolution , 1920x1080 doesn't shown in list and just keep 1920x800.

Description3

I found no matter I connect which monitor , it can't re-detect till I restart PC, so maybe it keep

last status.

Q2.How can I set to let PC can re-detect monitor when I connect a monitor every time.

PS. DVI and HDMI work normal and can read correct EDID.

I change other OS PC (windows/8/10 with intel 620) and no problem.

Thank you a lot.

Hello @hachu

Thank you for posting on the Intel® communities.

In order to understand better this request and review this further, could you please confirm or provide us with the following details?

1- When you said "can't read correct EDID with moninfo" (Description1), do you mean you are using the tool "Monitor Asset Manager 2.9"? Is this correct?

If not, could you please confirm the exact name and version of the tool you are using? You may also share a link as a reference.

2- When you said "I have check registry, it seems not correct." (Description1). What exactly do you mean by "seems not correct"?

What is "not correct"? What is the exact problem/behavior that this is causing? Please provide more details.

3- Why are you trying to read EDID from the monitor? Is this to review some information/capabilities, to debug an issue, or for development purposes (hardware or software)?

4- Maker and model of both monitors:

5- When you said "Then I changed the A monitor to B monitor(1920x1080), it still keeps to A monitor (1920x800), status and can't adjust the resolution, 1920x1080 doesn't show in list and just keep 1920x800" (Description2).

Is "monitor B" also connected via VGA cable?
Where are you trying to set resolution 1920x1080 for "monitor B"? Is it on the Intel® Graphics Command Center Display settings? Or is it on Windows* Display settings?

6- Regarding this behavior: "I found no matter I connect which monitor, it can't re-detect till I restart PC, so maybe it keep last status" (Description3).

Just to make sure, when the monitor "cannot be re-detected", what is the exact behavior? Is it not giving any display/image on the screen (a black screen)? Please elaborate more on the exact behavior:

7- Please provide a Report for Intel® Graphics Drivers following the steps on the link. Make sure the monitors in question are connected to the computer when running the report.

8- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system:

Download the Intel® SSU and save the application on your computer
Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
To save your scan, click Next and click Save.

Hi, Andrew ;

Thank you for your reply.

I send a mail to you , I don't sure you receive it or not.

And I try to explain more to you with some photos.

So if you don't receive it, I will try to reply here.

Thank you again.

Best Regards,

Hi, Andrew ;

It seems can't reply by mail directly, I reply here again.

1- When you said "can't read correct EDID with moninfo", do you mean you are using the tool "Monitor Asset Manager 2.9"? Is this correct?

If not, could you please confirm the exact name and version of the tool you are using? You may also share a link as a reference?

Ans : Yes , I used Monitor Asset Manager 2.9.

2- When you said "I have check registry, it seems not correct.". What exactly do you mean by "seems not correct?

What is "not correct"? What is the exact problem/behavior that this is causing? Please provide more details.

Ans:The registry was same Monitor Asset Manager 2.9 read, but not correct. So I don't sure how registry was written from EEPROM or other.

3- Why are you trying to read EDID from the monitor? Is this to review some information/capabilities, to debug an issue, or for development purposes (hardware or software)?

Ans : I want to use this PC with Monitor Asset Manager 2.9 to test our AD/B and check the EDID was correct or not.

4- Maker and model of both monitors:

Ans : We are a AD/B design company. The monitor's AD/B was our product. I try same condition with 2~3 different PCs, but only this PC (Win 11 with 630 graphics) has problem. In this Win11 PC , the DVI & HDMI source was no problem when you connect DVI/HDMI cable to monitor you can see the PC detect new one every time but VGA source can't, it just only detect 1 time in first power on PC and always keep this monitor's status till you re-start PC.

PS. No matter the AD/B we designed or customer designed were same result, but other PCs

(Win10+graphic 620, Win8+graphic 4600) were no problem.

5- When you said "Then I changed the A monitor to B monitor(1920x1080), it still keeps to A monitor (1280x800) status and can't adjust the resolution, 1920x1080 doesn't show in list and just keep 1280x800"

Is "monitor B" also connected via VGA cable? Where are you trying to set resolution 1920x1080 for "monitor B"? Is it on the Intel® Graphics Command Center Display settings? Or is it on Windows* Display settings?

Ans: Only VGA has problem ,DVI & HDMI was OK. Intel Intel® Graphics Command Center Display settings & Windows* Display settings are same result.

I enclosed some photos for explain to you .

1.Connected to A monitor (1280x800)

The EDID was not correct but the display was normal, you can compare follow 2 photos. It's same monitor but different EDID.

2nd photo was read by other PC (Win8+graphic 4600)

2.Then connected to B monitor (1920x1080)

Monitor Asset Manager can't be shown correct EDID, it seems empty but actually the EDID was existed.

B monitor's correct EDID.

You just only can see the resolution keep as A monitor not B and till re-start PC.

6- Regarding this behavior: "I found no matter I connect which monitor, it can't re-detect till I restart PC, so maybe it keep last status".

Just to make sure, when the monitor "cannot be re-detect", what is the exact behavior? Is it not giving any display/image on the screen (a black screen)? Please elaborate more on the exact behavior

Ans : Just only removed VGA cable from A monitor and connected to B monitor , no other setting or behavior, it always keep A monitor's status . If A monitor resolution was 1280x800, B monitor was still keep 1280x800, and the resolution list can't show B's correct resolution as I mentioned on item 6.

7- Please provide a Report for Intel® Graphics Drivers following the steps on the link. Make sure the monitor in question is connected to the computer.

8- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system:

Download the Intel® SSU and save the application on your computer Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View". To save your scan, click Next and click Save. Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

Ans: I will try to do it.

Hi, Andrew

I attached a report for your reference.

AndrewG_Intel · ‎06-16-2022

Hello hachu

Thank you for your response and for all the details.

Before we move to review this further, and just to make sure we have the proper information, could you please confirm the following details?

1- What do you mean when you said "AD/B"?

2- Checking the website for "Monitor Asset Manager 2.9" it says it is supported "under every Microsoft OS from NT 4.0 to Windows 10". There is no mention of support for Windows® 11. Have you checked with them if this is correct or if it is supported also for Windows® 11?

Note:

We apologize for the inconvenience, but we didn't receive the email since there is no option for users to initiate an email conversation regarding a thread. We appreciate you shared all the information here in the thread.

Hi , Andrew ;

Thank you for your reply.

1.AD/B means Analog to Digital board, every monitor has this PCBA.

2.Actually , I don't have other PC with OS Win11 can double check this issue.

Even so Monitor Asset Manager 2.9 cannot support Win11 , the PC should be detected monitor

when connect one every time but it was not.

And as I mentioned , it just VGA source has problem , DVI & HDMI was no problem.

It shouldn't stay stuck on the previous monitor all the time even change to other different monitor, it's my opinion.

Best Regards & thank you again,

hachu.

Hi, Andrew ;

Updated my test result for your reference.

I install a graphic card (ASUS EAH5450) and connect to monitor through VGA source.

All my problem almost solved except it can't auto-detect when connect a monitor,

but it can manual press detect to solve , unsatisfactory but acceptable,

I hope it can auto-detect when connect another monitor.

I don't sure it's Wndows11 feature or not.

From some reasons I need a PC with Intel's graphic.

Although above test seems can solves the problem, but it's not what I want.

Best Regards,

hachu.

AndrewG_Intel · ‎06-23-2022

Hello hachu

Thank you for your response.

From the Intel® Graphics Command Center app, it is possible to pull a graphics report that includes EDID information. We may use it to check the differences between the EDID information on the apps. You may also check the information from both tools and let us know if you notice any difference or something that we should examine.

Please provide the Report for Intel® Graphics Drivers following the steps on the link. Make sure the monitor in question is connected to the computer when running the report.

Also, please confirm the following details:

1- By any chance, if you test another monitor from a different brand with VGA port, does the app read it well?

2- Just to make sure, when using the graphics video card ASUS* EAH5450, did you also check the EDID using Monitor Asset Manager 2.9? Do you get "correct EDID information"?

hachu · ‎06-24-2022

Hi, Andrew ;

I enclosed Report for Intel® Graphics Drivers as attached file "Intel® UHD Graphics 630 - Friday, 24 June 2022.txt"

1- By any chance, if you test another monitor from a different brand with VGA port, does the app read it well?

Ans: No , it is still incorrect or empty EDID. But EAH5450 was always correct.

2- Just to make sure, when using the graphics video card ASUS* EAH5450, did you also check the EDID using Monitor Asset Manager 2.9? Do you get "correct EDID information"?

Ans:Yes , I always use Monitor Asset Manager 2.9 to read EDID. You also can see the correct EDID as attached file "OK edid.jpg"

Maybe you can compare EDID from Graphics 630 and EAH5450.

I don't know why same PC can read different EDID by different graphics.

Hello hachu

Thank you for your answers and for the Graphics report. We will review this and once there is additional information to share, we will post it here in the thread.

Hello hachu

Thank you for your patience in this matter.

After reviewing this further and considering the app specs it is showing OS support (x86 and x64) list below:

Windows 10

Windows 8

Windows 7

Windows Vista

Windows XP

Windows Millennium

Windows 2000

Windows 98

Windows NT

Windows 95

In this scenario, we cannot warranty this works with Windows® 11 as per third-party tool specifications.

If EDID is showing correctly on HDMI & DVI works we can understand graphics are ok. Our recommendation is to try a VGA adapter to DP or HDMI and see if that works.

Also, we recommend contacting the Original Computer Manufacturer (OEM) and verify VGA and Windows 11 are compatible and supported.

Hi, Andrew ;

Thank you for your reply.

I understand the app didn't support Win11.

But my problem was that there are 2 different graphic card in this PC with OS win11,

why 630 can't read correct VGA EDID, but external graphic is no problem.

If due to the app can't support OS win11, the external graphic should be had same problem,too .

It's my opinion.

PS. I have asked Original Computer Manufacturer same question but not reply yet.

Thank you again.

Best Regards,

Jean_Intel · ‎07-13-2022

Hello hachu,

If I may jump into the conversation. I want to clarify that the VGA is no longer natively supported; thus, the VGA is an OEM implementation by converting DP to VGA (Digital to analog), and this in itself can cause the EDID issues you mentioned. So, I recommend you refer to the OEM for further information and support.

Also, it is important to mention that the app has no information about whether or not it works on a Windows 11 environment, so we can't warranty this application would work with Windows 11.

Best regards.

Hi, Jean ;

Thank you for your information.

May I know it's Intel graphic chipset feature??

Or which H/W version was implement no longer natively supported?
