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
