U3419W, MacBook, USB Type-C, sleep/wake issues

Hi Robert, thanks for your reply. I got my monitor last month and the firmware update you mentioned was already applied. This doesn’t resolve the issues I’m having. 

Jp1984,

Does the U3419W produce the same issue when disconnected from the Apple and connected to a tested/validated Windows OS PC? Or during the stand alone Built-in Diagnostics (page 64)?  

Unfortunately, Dell did not test/validate the U3419W on the proprietary Apple OS or hardware, so our support is limited to the U3419W functioning with a tested/validated Windows OS PC.

You can see from the U3419W driver page that we did not provide specific Apple OS drivers. We only provided an Apple OS firmware update option.

The U3419W User’s Guide never mentions Apple.

The U3419W Monitor Usage and Troubleshooting Guide only mentions Apple in respect to changing the DisplayPort mode from DP 1.2 to DP 1.1.

Would you be able to send me that U3419W Service Tag number so I can document our discussion?

Thanks.

Since we haven't heard from you, we will be archiving our case.  Should you need further assistance, please reach out to us again.  Thanks.

Sorry for the delay, I monitored this actively for a few days then forgot about it. Please do not close this case as the problem is not resolved and the behaviour of this monitor is unaccepable.

Thank you for your comments. I am running the latest monitor firmware.

I think the fact I am using a Mac is a red herring - the real issue here is that the monitor flashes and beeps when it loses signal on an non-active input. A secondary issue is that this in turns sends a signal down the USB-C and wakes the Mac and makes the monitor flash and beep again.

If I am using display port as my current active input, I do not want to see or hear about the state of other inputs.

What can be done to fix this problem?

Thanks

Based on what DELL-Robert P stated above, "Dell did not test/validate the U3419W on the proprietary Apple operating system or hardware, so our support is limited to the monitor itself.", you NEED to find a Windows OS PC and test the U3419W on it.

I do not have access to a Windows USB-C device and fail to understand how that is related. I have my monitor making obnoxious noises and flashing messages while charging a device over USB-C when I am using a completely different input. This is not about Apple, it is about how this monitor behaves.

And if support is saying Apple is related to this problem, then I would like to mention that I didn't see any warnings about this moniotor not being compatible with Macbooks when I purchased.

Today I tried usinga separate power adapter to charge my Mac while connected to the monitor. It stops the charging sound, but I did notice my monitor wakes up once in a while and displays a message saying it's looking for signal. I wish it would just stay black until I wake up my MacBook.

It is very disheartening to hear a Dell employee saying "Dell did not test/validate the U3419W on the proprietary Apple operating system or hardware" in response to a problem that many people, including myself, are having with the monitor. The U3419W is clearly intended to function correctly when being used with a variety of devices, and Dell certainly has a responsibility to its customers to at least test basic functionality of connected Apple laptops, when those laptops represent at least 12% of the market.

Has anyone tried the 8/19/19 Apple MAC OS/9 firmware M3B106 (Dell_U3419W_FWUpdate_M3B106_macOS.pkg)?

So the new firmware allows the monitor to charge via USB-C when it's turned off, but unfortunately my MacBook keeps making the 'ding'-sound once regularly, as if it's being connected to a new power source. It appears the monitor doesn't provide a continuous charge.

I'm glad I no longer have to see the monitor light up and show a message that it's looking for signal, but it only solves half of the problem. 

I hope this update shows Dell is listening to our complaints and takes their Mac customers more seriously and that we can expect another update soon that fixes the other issues.
