B580 No displayport until windows (can't view bios)

ZeeKay — Mon, 27 Jan 2025 04:04:54 GMT

From searching around I seem to be having the opposite problem of other people. I have a Sparkle B580 and I am unable to view the bios when using displayport, and it does not work until Windows and the driver loads.

The bios does work great with HDMI and no delay or anything in the monitor waking up.

With DP it will be in an 'on' state but a black image until windows, no bios or splash screen.

The monitor is an older 34UM94-P, with DP 1.2.

Windows 11 Pro, Driver 32.0.101.6259.

Hello ZeeKay,

Basically, your BIOS shows up fine with HDMI but not with DisplayPort, which only works once Windows and the driver load. This could be due to driver issues, so make sure you have the latest driver. Sometimes, an older driver might work better. It might also be a compatibility issue with your monitor's DP 1.2 version. Check if there's a firmware update for your monitor. Also, look into your BIOS settings to ensure the primary display output is set correctly. Using a high-quality DisplayPort cable can help too. If nothing works, you might have to stick with HDMI for BIOS access and switch to DisplayPort once Windows loads.

Sparkle only provides/links to the official Intel drivers. There is no firmware available, and other GPUs have worked fine in the past with this monitor.

Hello ZeeKay,

To further investigate the issue may I ask for additional information about the system?

Can you please run the System Support Utility (SSU) and share the logs with me?
What is your previous graphics card installed on your system?
Did you try to updates graphics driver? if yes, how did you perform the last update? Did you use a device manager-clean installation or Display Driver Uninstaller (DDU) before updating to the latest graphics driver?
Any software or hardware updates on the system aside from GPU?

Providing this information will help me diagnose the system more accurately and check for available solutions. Thank you for your cooperation, and I look forward to your response.

Best regards,

Randy T.

Hey Randy,

1. SSU output is attached

2. This is a new build, previous PC worked with display port in bios with this monitor

3. This is the latest driver from the Intel website, there were no previous drivers as this was a new build and fresh Windows install. The issue happened from first boot.

4. Again, new build. There was not a change in behavior, it just never worked. Displayport never shows the bios (and is black until Windows loads), but HDMI works fine.

Hello ZeeKay,

I recommend trying the following troubleshooting step to address the instability issues you've been experiencing:

Troubleshooting Steps:

Deactivate FreeSync: Access your monitor's menu and turn off the FreeSync feature.
Check Display: Verify if BIOS is now displayed on the monitor using DisplayPort.
Restart: Restart your computer.

Please let me know the results after you've had a chance to try this.

Best regards,

The monitor does not support FreeSync so this is not possible to disable

Hello ZeeKay,

I wanted to clarify some information, could you please provide answers to the following questions?

Are all the DisplayPort (DP) ports experiencing the same issue?
Could you try using a different monitor to see if the issue persists?
Is the cable you're using a direct DP to DP connection?
When using the DP port, do you see a "No signal" message, or is the screen completely black?

Additionally, please check this article on resolving the "Black Screen, No Display Issue after Installing Intel® Arc Graphics Driver with AMD* Processor.

I do not have another DP monitor for testing

> Is the cable you're using a direct DP to DP connection?

> When using the DP port, do you see a "No signal" message, or is the screen completely black?

The screen is black, not 'no signal'. The screen wakes up as expected and simply shows a black image until Windows loads.

Disabling SVM was able to resolve the issue. I took the following steps:
Access bios via HDMI
Disable SVM (it was under an overclocking section for some reason, using the search function was useful)
Shut down
Unplug HDMI, use Displayport only
Reboot, now able to access bios via DP, and see the splash screen/Windows loading page

Thank you for the help, although I'm unsure of the effects of disabling SVM may cause.

Hrm, maybe not 100% solved. It seems to be some issue if its set to 60hz at 3440x1440? At 50hz it works fine, as if when I disable the DP 1.2 option in the monitor. This effectively caps it out at the HDMI 1.3 standard.

What I noticed was that when it did work, it wouldn't allow me to select the higher refresh rates in windows, such as if it didn't negotiate the higher DP1.2 speeds on boot. When I've rebooted since then, with 60hz showing available, the bios is not viewable. Disabling DP 1.2 in the monitor (reverting to 1.1) seems to allow everything to work fine, but is not an acceptable method.

Not really sure why it wouldn't be able to sync with DP 1.2.

No that is not related.

I shouldn't have mentioned it, but only noted it because if I disabled DP 1.2 (in the monitor), the lower resolution is the max. This is expected. However, in doing so, the bios shows via DP (running 1.1).

Windows works in all cases and any driver or settings there don't seem to be applicable. I would think this is more of a firmware issue preventing the EDID from being read or something, I'm not really knowledgeable on that.

Hello ZeeKay,

Can we try using a different DisplayPort cable to see if the issue persists? because based on Display Configuration of this card it should work with these resolutions 60hz at 3440x1440.

Ensure that you are using a high-quality DisplayPort cable that is certified for DP 1.2. Some cables may not support the full bandwidth required for 3440x1440 at 60Hz.

I can try, but it's weird that it would work in Windows in that case.

I have ordered a new cable as I did not have a spare as I thought I did. I will let you know the results.
