HD 520 flickering with latest drivers

Andrius — Wed, 30 Sep 2020 19:25:06 GMT

Hi, I’m facing issues using latest graphic drivers 27.20.100.8778 on Dell latitude 7470. Screen flickers, downgrade of drivers does not help, have anyone faced something similiar?

Issue goes away if using “dummy” ms driver.
Using Win Pro 64 bit
Version 2004
OS build 19041.508

This is a laptop. Laptops often have their drivers modified to support special features like focus and brightness adjustment. If the laptop has a dual-graphics solution, there is an even higher chance that the drivers have been modified to support the two solutions working together. As a result, I suggest that you return to the most-recent set of drivers that HP provided and see if they alleviate the problem.

Hi @n_scott_pearson ,

thanks for Your input on this

this is Dell Latitude. And I have used latest drivers from Intel (27.20.100.8783) as well as from Dell, I still face issues.

If I use generic driver provided by MS it works, or if I do force install HD 600 (26.20.100.7262) it works as well (except I can't start HD Graphics Control Panel by Intel).

Regards, Andrius

Can you post a video showing this flickering? People overuse the 'flickering' description for so many phenomena that I need to actually see what it is doing.

Ah. That's not flickering. That's a data glitch and a tear. Still, it is something that shouldn't be occurring.

@Ronny_G_Intel - can you get the team to look at this?

Hi @Maria_R_Intel

Does the issue the start just after the driver update?
Totally fresh install of Windows PRO 2004, and latest driver install
Provide the specific versions of the drivers you tested.
Here is a list which driver versions I've tried:
21.20.16.5127
21.20.16.5145
26.20.100.8142
27.20.100.7990
27.20.100.8581
27.20.100.8691

Are you able to test an external display? Please, let us know if the issue persists (provide a video if possible)

Yes, I;ve tested it. No glitch or tear on both screens (using Duplicate on both). Glitch (tears )starts only when I disconnect HDMI cable, but if HDMI is connected both screens are OK.

Regarding logs, I could provide you those, but not in public forum, since it contains Dell Tag, as well as some serial numbers.

Thank You

Regards, Andrius

Hello Andrius,

Thank you for the information.

I would like to check this internally, I'll post back on this thread as soon as I have more details to share.

Hello Andrius,

Thank you for patiently waiting. After checking this internally we found some steps that may help you with the issue, please check them below:

Change the refresh rate of the display.
Go to BIOS (Basic Input Output System) and load the default settings to perform any BIOS changes to contact the motherboard manufacturer. (Dell*)
Test the processor using the Intel® Processor Diagnostic Tool.

As per the previous steps performed we think that the issue may be with the hardware, this because the issue disappears when you connect an external display through HDMI*. Why?

Graphis portion of the processor
The screen itself of the laptop, because at once you connect to an external monitor the connection becomes stable
To confirm this and if the issue persists after the troubleshooting performed, please contact the Laptop Manufacturer.

Best regards,

Hi @Maria_R_Intel , highly doubt that it is HW issue. Installed latest Beta drivers (GFX Driver Version: 27.20.100.8873) no more issues.

Re:HD 520 flickering with latest drivers

Maria_R_Intel — Fri, 16 Oct 2020 21:38:23 GMT

Hello Andrius,

I am so glad to hear that!

Keep in mind that you are using a BETA driver, BETA drivers are provided just for testing and are not stables versions. However, is the base we use to develop our next stable version.

If you agree, I can let this thread open in case the issue came back or to test the new stable version that we hope to have soon available for our customers.

Re: HD 520 flickering with latest drivers

Maria_R_Intel — Thu, 29 Oct 2020 00:03:34 GMT

Hello Andrius,

We want to know if by any chance do you test the newest driver, version 27.20.100.8853? This is a stable version which includes the improvements we tested on the previous BETA driver you were using 27.20.100.8873.

Please, we encourage you to test this driver and install it with a clean installation:

Download the latest DCH drivers and save them on the computer:

Stable 27.20.100.8853 version.

Disconnect from the Internet so no new drivers are automatically installed by Windows Update.
Uninstall the driver and the Intel Graphics Control Panel from Control Panel > Programs and Features.
Restart the computer.
Confirm in Device Manager > Video Adapters the controller is listed as 'Microsoft Basic Display Adapter' > if not, repeat steps 2 through 4.
If the adapter continues to be listed as ‘Intel HD Graphics’ or similar, and no other Intel Graphics driver is listed under 'Programs and Features' for removal, then it means Windows has switched to a previously installed Legacy driver. At this point we can remove Legacy drivers from Device Manager:

Right-click on 'Intel HD Graphics' or similar, and select 'Uninstall Device'
In the pop-up window make sure 'Delete the driver software for this device' is checked.
Click on 'Uninstall'.
Restart. (Repeat steps 6.1.1 through 6.1.4 until the device gets listed as 'Microsoft Basic Display Adapter')

Install the DCH driver that was downloaded on step 1
Restart the computer.
Reconnect to the Internet.

Please, let us know the outcome, any feedback will be appreciated.
