Question DisplayPort to HDMI converter behavior

[isaacntk]

Hi, I just got a graphics card with 3 DisplayPort, 1 HDMI and 1 DVI-D port.

I also have one monitor which supports HDMI and DP. A second, old one which only supports VGA(connected to my motherboard for now planning to replace with another HDMI/DP monitor).
I just learned of this inexplicable behavior of DisplayPort that it is PnP and will destroy the windows extended desktop when I turn it off. So I switched to HDMI.

Here's the question. If I get another monitor, and use a DisplayPort to HDMI adapter, will that PnP issue still be present, as in windows' extended desktop will be removed on monitor off?
Or is using a DVI-D to HDMI adapter a better option (if so, what are the limitations of such a connection such as refresh rate or resolution)?

Or alternatively if there is a way to fix the behavior of DisplayPort (unlikely from what I've found so far)

Edit (System specs):
OS: Windows 10 (Update 1809)
GPU: Palit GTX 1070 TI
Monitors: Dell P2418D

Recommend that you update your post to include full hardware specs and OS.

GPU make and model likely being the most relevant.

Also include the make and model information for your monitors.

When using a DisplayPort to HDMI adapter, it behaves the same way as an HDMI device. When the monitor is turned off, it will not behave like the monitor has been disconnected the way a pure DP connection does.
