I suspect amdgpu_connector_dp_detect might need similar logic as
amdgpu_connector_dvi/vga_detect related to amdgpu_connector->detected_by_load .

It looks like this might be chipset/firmware specific.

I had this problem with MSI R9 270 Gaming 2G
(https://www.msi.com/Graphics-card/R9-270-GAMING-2G.html) which broke last week
(I couldn't power on computer). I replaced it with Sapphire Nitro+ Radeon RX580
8GB GDDR5
(http://www.sapphiretech.com/productdetial.asp?pid=B66182B7-1EA6-42A9-8762-FCCE003B491A&lang=eng)
which does not exhibit this behaviour even though the rest of the system is the
same: same hardware, same OS.

Now when running:
sleep 5; xset dpms force off

monitor goes permanently into sleep.

Correction : this happens to me on RX560 card - R7 240 was the one that worked
fine. It happens with 1xAcer 1x Dell monitor combo as well 2x Lenovo ones - so
monitor brand doesn't seem to matter.

5:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin
[Radeon RX 460/560D / Pro 450/455/460/555/560] (rev e5)

Also to answer your question it happens when I set it manually using xset dpms
force standby for example. But problem also happens when desktop tries to enter
dpms state - tried with various distros/GNOME/KDE with same results - the
monitor fails to go to sleep. The difference being in the first case the screen
turns black for a second or so, monitor power light is still white and then the
screen comes back on. 

In the second case I either see grey screen with mouse some times and lock
screen in others but I am able to move the mouse and log back in - nothing
seems broken in either case other than the fact that both monitors fail to
sleep.

Just to add a data point - problem card in my case is a XFX Radeon RX 560. 
1xDP 1xHDMI outputs - disconnecting the DP cable from one monitor doesn't help
- same issue with single monitor over HDMI.
