S2721DGF, ongoing black screen issue
Hello All,
I want to post my ridiculous time today with Dell Technical Support. I also have the same issue as most with the black screen happening upon deep sleep mode when the idle times out on these monitors. It doesn't happen to just one monitor, it happens to both. Mind you, I have a 3 monitor setup, two 27" and one 32". All Dell's, and the 32" doesn't have the issue. Dell doesn't seem to want to fix the issue or resolve it. As a matter of fact, the technical support agent I was on the phone with today had the nerve to tell me I need to buy a "Dell System" for the monitor to be compatible. REALLY. So a Dell monitor is only compatible with a Dell system, what kind of statement is that? The agent kept trying to install software and some kind of dell system updater on my computer when I gave them remote access. He didnt even know how to use the log file gather batch file, and I had to do it.
The issue with these monitors is clearly an firmware issue. It never happens to my Dell 32" monitor, just the 27" ones. I have done all the recommended troubleshooting, replaced GPU, reinstalled Windows, ands nothing resolves the issue.
This is the email I received:
FROM: Dell Tech Support <technical_support@help.dell.com>

TO: Dell Tech Support
Excuse me, but a dell system that is compatible with a monitor? What kind of is that. That is the most ridiculous statement ever said from someone who was supposed to be a tech support agent. No, I will not be buying a Dell system, that is utterly ridiculous and for you to make a statement such as that, is completely unacceptable.
I will be posting this interaction online for people to see how dell fixes issues with their customers. So a dell monitor only works with a dell system? Is that the statement you really want to make here? I am a Network/System Engineer by trade. Work with all types of servers and systems each and every day. Forgive me when I laugh at the lack of intelligence in that statement! and make it a priority to identify the problem and understand the customer issue!

<Do not start multiple threads. Merged this to your original thread. DELL-Admin>
Today I contacted Dell Support for my S2721DGF going black after powersave, and would not show anything until I pull the power cord and reset the monitor. The screen is black when this happens, it is no longer lit. The power button -is- lit. The screen does not drop from Windows provisioning (e.g., my second and third screen does not start acting as the 'main' screen) until I press the power button. The sound of a device being disconnected also plays.

I love the fact that they don't know how to fix this and want to pass the issue to another piece of hardware! Latest reply from a Dell Supervisor who clearly doesn't know

Dear TONY,
Hope you are doing good! The monitor is a plug and play device. The issue you are reporting is a system setting issue. You will have to contact Asus for further support.
In case you need any further help with your computer, please contact us by replying to this email (DO NOT change the subject line). Once we receive your email, you will get a response from my team within 24 working hours or within the time-frame specified by you.

"How is it a system setting issue, when you unplug the DisplayPort Cable, the onscreen notification doesn’t appear and neither does the OSD. That, Sir is NOT a system setting issue. That Sir, is a MONITOR issue! As the uploaded video to the support representative was given that clearly shows that. Would you like to tell me another dishonest statement?"

To clarify,
* When troubleshooting the S2721DGF, the other two monitors and associated video cables should be disconnected from the computer. 1 computer to 1 monitor via 1 video cable.
* Do step #3 in the Pinned Posts, Read this FIRST before posting. Then retest
* When any Dell monitor is not connected to a computer video out port via the one video cable, the standard OSD menu is NOT supposed to appear. The only thing that should appear is the messages =

@DELL-Chris M
I understand how to troubleshoot the monitor and have a clear definition on what should and should not appear. In troubleshooting the black screen issue that "Many users" have complained about with this monitor, is when the monitor goes into a sleep mode, or even at startup from a cold state, disconnecting the DP cable, doesn't present the "NO DP CABLE" message when the black screen error is occurring. Nor does it show an OSD display as an preventative measure. The monitor is detected by the computer, the computer acts as if the monitor is working as standard, however the monitor itself has no display until it is power cycled/hard reset.
This is clearly one of several things.
There have been enough users in this forum with NO FIXES and all over the internet that have complained about this very specific monitor and the issues that occur with it. Some to which your troubleshooting assistance is posted with no resolutions. Dell has done nothing to resolve the issue specifically. Even the replacements for the ones that were replaced, didn't resolve the issue as the replacement monitors do the same thing.
Now, I have all DELL monitors, 3 in total. I have two of the S2721DGF's and one 32" G3223D that this issue as never occurred with. It's specifically the two S2721DGF's since new out of the box. I have replaced the video card, the DP cables, different drivers, reinstalled windows 11 and the issue follows the monitors.

So community, after repeated conversations with DELL SENIOR MANAGERS, they claim the issue is with the ASUS ROG STRIX VIDEO CARD and it's Power Delivery. WOW! More side stepping and passing the issue off to another manufacturer. They just don't listen, nor do they following instructions. Kept over talking me and when I would ask technical questions he would try to overtalk me mid sentence and shut me down so I couldn't talk, then wanted me to be professional about it. Since when does incompetence on this level deserve professionalism? I was not having that. They also want to replace the monitors but the last person I just spoke with said it's clearly the video card. I have never in my life experienced such incompetence on a level that is just comical from a company who clearly cannot understand the issue nor do they want to truly resolve the issue. Truth is they simply don't know how to fix the issue and just want someone to blame or point the finger at.
Professional incompetence at it's very best, thank you DELL!

More incompetence from DELL:
