If I use a slow laptop with a bad CPU to connect to a much faster desktop PC would the slow laptop look and act fast? Or would the poor CPU make experience slow on the laptop?
Thanks for posting.
You will be able to access all the power of the faster desktop PC.
The things that would make it seem slower is:- TeamViewer works well with low bandwidth, but if your connections latency is high or if the connection is unstable this may affect your experience
- The Slower PC still needs to have the power to render the image from the remote side.'
I hope this helps -Scotty
So as long as the laptop has power and a decent internet connection, it will be able to mirror the desktop PC's screen even if it has a terible CPU or GPU for example?
