Hello,
About 2-10 times per day my U2415 suddenly shows an error message reading "Current Input timing or resolution not supported." even though it is never run with any other resolution or input timing than it requests. It is also shown in the OSD menu.
I then have to turn the monitor off and on and the problem is gone. Even though it's quite easily fixed, it's still really annoying when gaming or working.
What I tried so far:
- I changed the cable from the DP to mDP provided by Dell to a new high quality DP to DP cable (link above).
- I uninstalled the graphics drivers completely and reinstalled the latest.
- I did a factory reset on the monitor changing nothing afterwards except the color scheme.
- I unplugged the USB connection, having the monitor only connected to elictricty and the DP of my PC.
- I tried out DP 1.2 in the OSD options.
- I changed the input timing from 59 to 60 Hertz in the windows options (changes back after reboot).
- I ran the monitor with and without Dell Display Manager software.
Nothing I tried resulted in a state where the problem did not occur. I bought the monitor in April and the problems started about 1 month after purchase if I remember correctly. I don't know what I could have done at that time that could have caused the issues.
Sometimes the problem occurs 3 times within 10 minutes (when gaming), sometimes it occurs once in multiple hours. I occurs when gaming as well as when working on the desktop in text editors.
Since I configured Windows a few days ago to turn off the monitor after 5 minutes of idle, I also sometimes encounter an issue when waking up the screen. It then shows a washed out picture with white snow above the screen. When I restart the monitor, it's gone.
I don't think the 2 problems are necessarily connected and I can live with the second one which only occured once or twice but the first is really annoying. I found a lot of threads about the same issue but most of the time it was people who got the error message already on boot and there was never a solution that I could try for my case.
Can you please help me?
Best regards,
Manuel Fink

On all ports, the maximum is 1920x1200 60Hz, so it would not hurt to test video card HDMI out --> HDMI to HDMI cable --> U2415 HDMI in to see if the issue continues. if it does, get it exchanged. If it does not, then I would suspect the operating system and video card driver and how it interacts with DP and mDP.

It's hard to say if it's the graphics card or the monitor that's the problem. I got this "unsupported timing" message on my U2515H during the BIOS part of boot, using my GTX 260 card with a DVI to HDMI adapter, but changing to a different card (an R7 250), the BIOS displayed fine.
In your place I would use HDMI since there's no advantage in using DVI unless you're daisy-chaining, but obviously wouldn't be happy not knowing whether the monitor is faulty. If you could get hold of a different graphics card with DP to test, that would settle the issue. Maybe buy a new card and send it back if it doesn't fix the problem?

Hey everyone,
Thanks for the answers!
The last week I have been lucky and only got the error once. I am not 100% sure but I suspect that it was caused by my phone that I used to lay right beneath the monitor (sometimes charging it via the monitor's USB port).
However, I also got the error once yesterday with the phone in my pocket.
I can live with it for now if it occurs that seldom. If it goes back to occuring more frequently I will try an HDMI cable next as you suggested. It would certainly make sense to test it on another graphics card but right now that is too much of a hassle for me.
Apart from that problem, I'm totally in love with the monitor btw. The image quality is superb and I like the slim bezel and 16:10 format. Now if only the foot stand was black like the rest of the monitor... Maybe on my next Dell monitor? :)
