P2419HC, connectivity question

Dell P2419HC

Dell P2419HC

I goofed and bought a used P2419HC today, and it requires a USB-C connection. None of my computers has USB-C . Yes, it's my bad, the seller showed the monitor working on a video plugged into her laptop, she was supplying the cables, I assumed it was HDMI, and well, here I am. Plugging in HDMI half works, except that the monitor times out after a number of seconds insisting that it MUST HAVE USB-C to function.  Short of adding a card to provide USB-C to the desktop where I was hoping to use the monitor, I was wondering if I could use a USB-C to USB-3 cable and power the monitor that way?  Thanks for your help, and sorry for the duh-uh question.

I'm sure you will have success with using the HDMI port for your (old?) monitor and DP for your new dell monitor. 

Please note this Dell monitor has 2 Display Ports, (in and out) and only 1 will do what you want.  

So don't connect the computer to Out port. (usually has an orange cap on it)

Does your existing monitor have a display port? 

Please note normal USB-C ports do not output video. You need a Thunderbolt port for that or a DP enabled port. 

They look the same.

@Andy K​ Success, at last. The new to me Dell monitor is on the left.

I was able to connect it using DP to the one available DP socket on the Nvidia Card.

Worked perfectly.  Took a little while to juggle things around to get the screens in the right orientation so the one on the left is an extension of the one on the right which is the main screen, but 5 minutes took care of that. 
Thank you and @DELL-Chris M for sticking with me.  I appreciate your help. Now I can get down to working with my music notation program and with PremierePro on this machine.

The online P2419HC User's Guide pages 10 and 13 shows us that it has the following video in ports =
HDMI
DP
USB-C

Using PC HDMI out --> HDMI to HDMI cable --> P2419HC HDMI in port should work and not require anthing connected to the USB-C?

Do any of your computers have DP out port to test to see if the same message appears?

@DELL-Chris M​ Thank you for your response, Chris.  I had the User's Guide open when I made the connection from the HDMI in port on the monitor.  I got a message saying it was doing something with the signal and a progress bar.  When the bar got to about 25% I got the message that no USB-C connection had been detected, and the monitor was going to shut down. I was wondering if I could plug the male USB-C piece of the device shown below into the monitor's USB-C port, then run a USB-A 3.0 cable to my PC, if that could work?

None of my computers have a DP out port.
I have a medium level dedicated NVIDIA video card in the computer I want to use with the new to me monitor.

I can't remember if I have an open PCI-E slot, but if I do, if the adapter solution I'm asking about here won't work, I'll go shopping for one of those.  If you, or anybody else, have any recommendations for reliable cards at reasonable prices, please let me know here.

That USB-C to USB-A dongle --> USB 3.0 cable should work. But before doing so, open the Menu -->Input Source.
- Be sure HDMI has the check
- Turn Auto Select to Off
- Exit the Menu saving changes and retest

You can't use a USB  A>C adaptor for Video.

That monitor you purchased is a good standard. It accepts video over USBC, DP and HDMI. I would be surprised if your PC had non of those! Look for an HDMI connector on it.  And the use HDMI cable

As said, go into the input menu, and select HDMI or whatever (go away from auto)

I wonder if the 25% progress bar was coming from your computer? And at that point it switched off the video output. 

the monitor went hunting for another active video source, couldn’t find anything and switched off ?

@DELL-Chris M​ Thanks for your reply, and thanks Andy K for your input as well.  As to where things are:  if there was a mistake to be made, I've made it.  I plugged the HDMI cable into the motherboard socket; I should have plugged it into one on the GeForce GTX360 graphics card instead.  When I did that, the monitor lit up and worked, no USB-C cable seemed to be required.

But, the version of the gtX360 that is in my machine only has ONE HDMI slot, so that can't work for me.  It does have an unused DP slot, and as soon as the cable arrives from Amazon on Saturday, I'll hook it up, and I think it will work like that.  Will let all y'all know the outcome. I investigated HDMI "splitters", but the reasonably priced ones only work in mirror mode. I will want "extend" mode, so looking at the different options, I'll try for DP first. Second up will be a USB-C card. I do have an open PCI-E slot in the machine, and I may spring for a USB-C card, just to have that capability in this machine. 

Thanks for walking through this with me.
