Do TV's obey PC "sleep" commands?

[Gimpymoo]

I know not a "monitor" but do TV's obey "Sleep" modes from a PC?

Maybe they do not but my LG stays active when told to "sleep" as you can see the backlights on the screen, does not fully goto standby.

Oddly, it never shows "no input" either meaning the PC is giving it a "black" screen rather than zero output.

Any way of working around this?

Thanks.

What I am confused with is that when it detects "no input" from a STB or other source, it does have a "no input screen" but with the PC, it always detects an input, for example when PC is told to put monitor to sleep, but instead of detecting NO Input, it detects a blank screen. Odd.
