Second Monitor automatically start up with IMac.

Hi, I've just recently purchased an OMEN monitor for my IMac. It works great side by side with my IMac. One day I was going through my login items and saw something I wasn't sure what it was. So I deleted it without thinking about it. The next day I realized what it was. It was the start up for my other monitor. Now whenever I shut down my IMac or it automatically shuts down, I have to manually turn on the OMEN monitor. I know its not a big deal but I was wondering if there was a way for me to get that login item back. If you need the specs of the OMEN monitor or my IMac just ask. Anyone have a fix?

iMac, macOS Sierra (10.12.4)

They are basic Apple resets that do not disturb any of the User Data on the computer. What they do, is clearly explained in each of the articles.

They could very well osmosis your Mac into recognizing the connection path and monitor, like they have for so many other users.

Not sure why the monitor would needed a startup item to work or turn on. If it is connected using a Mini DisplayPort to Display Port cable or an HDMI cable, then your iMac should automatically recognize and wake it from standby mode. If not, then I would check in the monitors menu to see if the Source is set-up correctly.

If the monitor's Source is set correctly, then reset the iMac's

SMC as per > Reset the System Management Controller (SMC) on your Mac - Apple Support

and then the NVRAM, as per > How to reset NVRAM on your Mac - Apple Support

to see if that solves the problem.

not sure what an omen monitor is but if it connects by other then hdmi, DisplayPort or dvi or vga

but by usb or something it will require software running on the computer to operate and if that was the

software you removed from auto start then you will have to reinstall or reenable or manually start it I would say.

It is connected using USB Type-C to HDMI Adapter since there isn't an HDMI plugin on the back of my IMac.

OK good, USB-C to HDMI..

Did you check the monitors input Source...?

Did you reset the iMac's SMC and NVRAM...?

Ok, what exactly will that do? I just don't want to "reset" something without knowing whats all going to be effected by it. Sorry I'm not the smartest with these types of things.
