S2721DGF, black screen no OSD menu
Hey Dell team,
Yesterday my Dell s2721dgf monitor wasn't waking up when I powered on my PC. The screen is black (like power off black, not no-signal black) and the white power light is on. It seems to be stuck in deep sleep mode and not receiving and signal. My secondary monitor (also a Dell but different model) works just fine. This is the first time I've encountered this issue since owning the S272DGF. I typically power off my PC at the end of the day and boot it up in the AM. I've been doing this since I've owned the monitor and haven't ran into any issues until today. Here are some things that I've tried:
- Swapping display cables. I tried DP as well as HDMI
- Swapping computers. I tried getting the monitor to wake on my PC and Mac, no dice.
- Running a diagnostic check. I'm unable to do this because the monitor shows no OSD. Also, can't change auto-select input source for the same reason.
- I tried a power cycle per this reddit post
- Also tried multiple iterations of unplugging, holding the power button, then plugging back in like this response.
Haven't found anything that's worked yet. Any ideas what could be the issue here?
OS: macbook pro + windows
GPU: NVIDIA GeForce RTX 3060
Display cables: DP, HDMI
Edit: Some more troubleshooting information. On my Mac, the monitor is being recognized by the computer as display option but still the monitor doesn't wake. My PC doesn't seem to recognize the monitor as connected.

Confirming that you did the "No cables, power button reset" as shown here, (3) ?
If yes, to receive assistance from Dell chat Technical support, they need to first verify the warranty status. Click the "Get Help Now" icon on the right to start a live chat session. Provide to them the private S2721DGF Service Tag.

If the stand alone S2721DGF Self-Test (page 56) fails, the monitor is faulty.

For what it's worth, I tried downloading the latest drivers which didn't resolve the issue. Also downloaded the Dell Display Manager Application. This monitor is supported by the Display Manager Application yet, when I plug the monitor in and power it on, it states "Please connect a supported Dell monitor."
I guess the monitor is faulty. One day working, and the next day faulty.

I am running into the same problem with my monitor backlight going out and the LCD portion still working. I thought there was a power issue, but I have everything on a power conditioner. Furthermore, I have a P3421W connected also, and it is running fine. I have had 4 S2721DGF go out in this fashion (all replaced under warranty) with no solution with technical support yet. Anyone has ideas on what is happening, I would greatly appreciate it.

@Vandelbart @fuzzymango I found a post that apparently the monitor goes into Deep Sleep and needs to be reset. This feature requires a full power cycle of unplugging the monitor wait for the power to dissipate and then plug back in and plug back in the signal (HDMI/DisplayPort)

I have this exact same issue with both my monitors (2x S2721DGF).
Both of them got replaced by warranty, but this issue still exists today.
Unfortunately the OSD menu won't work, so the only way to get image back on the display is to power toggle both screens. This is very annoying to the point i'm wanting to change to other monitors and ditch these.
When they DO work, they are very good. Very high brightness and HDR. Also the responsiveness and 165hz for gaming is absolute great. This strange sleep issue is a very big downside of these monitors.
Buyers beware!
