HDMI does support DPMS. It just that TVs don't. I doubt well every see
a display port connector on a TV and/or DPMS support because that would
rob them of being able to have an almost identical product that is only
a slightly tweaked TV that is little to no cost to them that they can
charge charge a whole lot more for.

I think the problem is today is that they DO handle changing monitor
setups, but that they require devices to probably report themselves to
the system for it to work. For people using TVs, what they need to do
is have a checkbox that says something like, "Make the current setup
permanent". The checkbox would essentially break the plug and play
system completely and hard code each display to its function. The
computer would then spray video out the port no matter what, even if it
doesn't detect a device.
You mentioned that you were using curved Samsung TV. That is exactly
what I'm running as well. This probably won't help you, but maybe
someone else that's reading this; for my shut down needs I set the
computer to sleep the display after a certain amount of time which stops
sending video. Then I set the TV to automatically shut off after a
certain amount of time with a loss of connection. Now all I have to do
it wiggle the mouse or press a key to wake the system up and press power
on the TV when I want to start using it.
