Dell P2419H monitor will not wake from sleep with HD Graphics 530

[Kali]

There are two monitors connected to HD Graphics 530:

1 - Dell E2310H monitor connected DisplayPort to DVI. It behaves as expected, no problem.

2 - Dell P2419H monitor connected DisplayPort to DisplayPort. It works properly on boot up, but when being woken after sleeping it displays the message: 

The current input timing is not supported by the monitor display. Please change your input timing to 1920 by 1080, 60 Hz or any other monitor listed timing as per the monitor specifications.

Based on other similar posts, I have:

- confirmed that the display settings are correct. 1920 x 1080 @ 60 Hz is the native resolution for this monitor

- updated BIOS and all drivers

- swapped cables

- I installed an old NVIDIA Geforce 230 graphics card, and connected both monitors to it and they both worked properly.  When I noticed an updated graphics driver being automatically installed earlier this week, I removed the NVIDIA card and reconnected the monitors to the HD Graphics 530, but alas the problem was not resolved with the updated driver.

The problem can be worked around by (1) turning off the monitor then turning it on again, or (2) changing from extending the display to just using one monitor, then extending the display again. Either method is only workaround, a nuisance, and not a fix. 

Any solutions? or suggestions? Thanks.

4. Generate report.
5. Save the file. 
6. We will be waiting for your answers.

Hi Jose

Thanks for your help with this issue. The Intel System Support report is attached.

Here are the BIOS power options:

Checked:             Runtime Power Management

Checked              Extended Idle Power State

Unchecked:        S5 Maximum Power Savings

Checked:             SATA Power Management

Checked:             PCI Express Power Management

Checked:             Power On From Keyboard Ports

Unchecked:        Unique Sleep State Blink Rate

I could not find any specific option to allow/disallow the device to wake the computer. Since one of my monitors wakes without a problem, I presume the problem lies elsewhere.

I forgot to mention in my first post that I also tried disabling DDI/CI on the monitor, without success.

Thanks again for your help.

Hi Kali,

Thanks for your response.

Please provide the missing information to check;

• Provide an Intel® Graphics Command Center report.

1. Open Intel® Graphics Command Center.
2. Click on support.
3. Click on the tab System Diagnostic.
4. Generate report.
5. Save the file. 
6. We will be waiting for your answers.

• Provide a DxDiag report

1. Open Intel® Graphics Command Center.
2. Click on support.
3. Click on the tab System Diagnostic.
4. Generate report.
5. Save the file. 
6. We will be waiting for your answers.

• Is it possible to use an HDMI to HDMI connection? if yes, please use it and let us know if the issue persists.

• Verify Monitor updates and firmware.

• Install the latest driver Version: 27.20.100.9126 https://downloadcenter.intel.com/download/30100/Intel-Graphics-Windows-10-DCH-Drivers
• It is important to know that is recommended to use the original equipment manufacturer drivers, since they are the ones who build your system and know the components and the structure they have, also they release firmwares, patches and drivers for every system to work correctly, the ones from Intel are the generic ones.
• If the issue persists after using Intel drivers, please use the ones from your manufacturer.

Regards.

Hi Jose

I tried each of the steps you suggested, including checking for monitor firmware updates, using the latest Intel driver, then using the latest HP driver. Nothing worked. Since everything failed, I started troubleshooting from scratch again, and discovered the problem was resolved with a new DisplayPort cable. 

Thank you very much for helping me resolve this issue. Although it proved to be unrelated to the Intel driver, you were able to put me on the right path. Thanks again.
