  • Windows 10 - ver. 1809
  • ASUS ROG Strix Scar II - model "GL704GW-DS76"
  • NVIDIA GeForce - RTX 2070 8GB
  • 32 Gigs of RAM
  • Vizio 4K UDH TV - model D58u-D3

Brand new computer and when I connect the it to my Vizio TV the GPU(around 49%) and CPU(13.5%) spike and the power usage spikes to "very high" when I move the mouse. It is even worse when I am playing a game which reeks absolute havoc on my FPS.


After doing some elimination steps here is what I found. It only happens when the HDMI cable is plugged in to the computer and the other end is connected to an external monitor source. Once I unplug the HDMI from the computer it stops spiking. If I leave the HDMI plugged into computer and disconnect it from the external monitor it stops spiking.

So basically as it sits Windows 10 will not allow me to connect a large monitor and play games...


Is this normal? My guess is it's not so how can I fix this?


I have tried ever trick in the book aside from a reinstall (disk cleanup, clean boot, etc).


So again it only happens when an external monitor is connected via HDMI.


Any help is greatly appreciated,

Kevin
