The only downside I've found is the displays don't dpms power-down, so they'll go into screensaver mode and stay on until you power them off.  Which in turn triggers pretty much every linux desktop to freak out and do weird things when it loses all of its displays, so most time I just leave them on with their screensaver.  Last time I ran into someone with an actual samsung 30" 4k "monitor", it did the same thing, so caveat emptor.

When I initially got my 50in display, I found that I had to leave it on all the time to avoid the system freaking out, but that hasn't been the case for over a year.  I now setthe  GPU to shut off the display which doesn't actually shut off the display, but I have the TV set to shut off after a certain amount of time with no input.
I do have to turn it on my hand whenever I want to use the computer, but it's quick to power up and really hasn't been a big deal ever since they fixed the issues with the system freaking out because of a lack of displays.

There is also the possibility to use a USB to CEC adapter to shut down and wake up your TV.

I picked one of them up and got it to turn on and off the TV from a script, but I haven't been able to locate how to hook it into the power management properly to get things automated.
