I am using the dvi output with a dvi to dp active adapter cable.
No dp cable dell monitor u2415.
If you use the hdmi port for 1920x1080 then the image will not scale correctly it will be stretched vertically and there is no way to correct this using the monitor or windows settings.
When i start the monitor i get no dp cable.
To enable mst refer to instruction on section connecting the monitor for dp multi stream transport mst function.
I have tried swapping out the hdmi cable for another i have tried connecting the dp to usb 3 cable i ve tried installing the drivers etc.
Recently the monitor failed so i purchased a new dell u2415 monitor from amazon expecting it to work out of the box.
Other monitors can do 1920x1200 through the hdmi port but not this one.
Almost false advertising to call it a 1920x1200 monitor.
7 audio line out connect your speakers.
Dp 1 1 monitor can only be connected as the last monitor in the mst chain.
8 usb upstream port connect the usb cable that came with your monitor to the computer.
The monitor displays no dp cable so it does not recognize the active adapter cable.
This is one of the major reason that people have problems with this monitor.
Two cables were supplied with the new monitor.
I ve tried different hdmi cables but it still goes to sleep without waking up.
I hooked it up to my computer via an hdmi cable.
Dell u2415 won t detect displayport input.
I connect the dell to the laptop using a hdmi cable as there is no display port on the inspiron.
Dp 1 1 monitor can only be connected as the last monitor in the mst chain.
The default cable that is packaged with dell displayport capable displays is the mini displayport mdp to displayport dp cable if your system does not support a displayport connection you must purchase the appropriate cable for your system.
I tried both hdmi ports but no change.
I just purchased a u2515 monitor.
I tried an old dell monitor and it worked fine.
7 audio line out connect your speakers.
Got brand new dell u2415 monitor to go with it.
Now the computer says no dp cable and goes to sleep and won t wake up.
However when i attempt to connect the monitor i get no dp cable.
Here are the most common problems solution for the dell u2415 monitors.
One of the main weird feature of the dell u2415 is that you must enable the displayport input in the monitor menu before being able to use it.
Fortunately i have another very old monitor which i am able to use without which i would be really stuck.
