So I have recently installed host 188.8.131.52 on my Windows 10 x64 Dell E7450 laptop. I noticed something very strange. The remote screen is smooth when the lid is open. But when I close the lid, the screen update will be like one frame per 4-6 seconds.
The only difference I noticed is that when the lid is closed, the PnP Display lock (RU host monitor driver) disappears from the device manager and when I open the lid, the driver re-appears.
But what I don't understand is, I have anther 7-year old Dell E4300 running the same version of RU Host and Windows but it does not seems to show any difference no matter the screen status.
