Oh okay, thats a bit disappointing.  I can live with it I guess.  Was hoping there was some way to use a pointer to touch the buttons. Hopefully Dell won't make any more monitors with touch buttons.

Your only recourse is to leave it on all the time and set the operating system power management to "sleep" the monitor after 5 minutes of not using it. Then moving the mouse or pressing a key on the keyboard will wake the monitor up.

Not exactly what you're after, but would ordinary Windows shortcuts on your desktop work for you? If so, you can create shortcut on your desktop to switch inputs using Dell Display Manager, and to turn the monitor off and - on some monitors at least - turn it back on again.

Thanks I'll look into that.  Might work out well.  

This may not be obvious, but the shortcut command-line syntax for the U2414H would be as follows:

path/ddm.exe /n:SetActiveInput DP1   // to switch to DP

path/ddm.exe /n:SetActiveInput DP2   // to switch to miniDP

path/ddm.exe /n:SetActiveInput HDMI1   // to switch to HDMI/MLH1

path/ddm.exe /n:SetActiveInput HDMI2   // to switch to HDMI/MLH2

path/ddm.exe /n:SetControl D6 05   // to power the U2414H off

path/ddm.exe /n:SetControl D6 01   // to power the U2414H on again

where path is the full path to DDM and n is the monitor number in the DDM list if you have more than one Dell monitor. If you only have the one, then you can omit the n.

Since I just have the one monitor do I need the : before the  / ? Also it doesn't seem to want to switch back to display port once I switch it to HDMI 1. I set up hotkeys with Windows 10. Thank you for posting the power codes as I was using the set power mode option and it didn't seem to work very good.

Looks like once I switch to HDMI 1 the computer hot keys no longer work as I can no longer switch back to display port. Also the power off command works but I can't power back on.

Once you switch to DP, you need to execute the command on the DP side to switch back to HDMI. Typically, you can only execute commands on the active input port.

I tested on a U2414H and I can power the monitor off and back on again.

Oh I see, my computer is on DP and my PS4 is on HDMI. So I guess once I switch to HDMI I would be stuck there until I could push the on screen buttons? I set up the power commands like you said and only the off works. When I tried the hotkey command for the on command it doesn't work.

This is the on command that doesn't work for me.

"C:\Program Files (x86)\Dell\Dell Display Manager\ddm.exe" /SetControl D6 01

That's the correct command, and it works on my setup - perhaps there was a running change in the model revisions and/or firmware or you're executing it when the active input has been changed to the PS4. But since your other input is a PS4 and cannot run DDM, it doesn't sound like this is helpful anyway...  

It appears my monitor loses connection from the PC when I turn it off hence why the power command fails.  Any ideas?

I'd like to be able to use the power on command with a hot key but it doesn't allow me to because the display disconnects when I power it off. I'm connected via display port in Windows 10 with a Nvidia GeForce 660 GTX. I have the latest driver installed for the video card and the driver for the monitor installed. Is there something I need to do with the on screen menu of the monitor? Since I only use this monitor and a TV is a secondary display I didn't set the display port to 1.2.

I'm using AMD graphics and that could explain our different results. Even though the monitor is still connected, NVidia may be dropping the connection because it senses the monitor is powered down. I'm afraid it is up to the graphics/display driver, not the monitor, to establish and maintain connections. Because of that, it is possible that new drivers from AMD could break my setup, and new drivers from NVidia could make yours work.

If you are forced down this path, I think you'll find the buttons on the P-series of Dell monitors are better suited to your needs than the buttons on the U and S series.

Thanks for your help. I will have to look for something else.
