Can You Plug Monitor Into Motherboard & GPU
Plug monitors into the motherboard or GPU. If you plug it into an uncharged battery, then the charge will go straight into that battery and not be wasted on powering a monitor. For example, if your laptop is plugged in but has no power left for its battery, it's best to use the power from your wall outlet instead of using up more power from your laptop's charger by trying to charge both at once. The same principle applies with motherboards and GPUs as well - they don't need a monitor plugged in all the time!
Plug Monitor into Motherboard or GPU using an extender cable Unplug monitor and place somewhere safe where it won't be wiggled or unplugged by accident, such as your laptop bag or your pocket If you're worried that the motherboard/GPU might lose power, use a surge protector with battery backup to spare yourself from data loss and downtime.
You can find these at any general electronic store such as Best Buy or Radioshack. Plug the monitor into the surge protector with battery backup.https://motherboardinfo.com/plug-monitor-into-motherboard-or-gpu/
