1DGJSX1 isn't a PC model number. Your model will be "Inspiron" followed by a # or "XPS" followed by a #.
How are you trying to turn the monitor back on?
If mouse/keyboard don't do it, go into Device Manager and find listing for USB root hubs. Double-click each one and then click the Power Management tab. Uncheck box "Allow PC to turn off..". Repeat for all USB root hubs.
Then find Human Interface Devices in Device Manager, open each entry and if it has a Power Management tab, uncheck the same box. Exit DM.
Now open your Power plan and click Advanced Options. Look for USB settings on the list and disable USB Selective Suspend. Save the change and exit.
Reboot and see if that helps...
