Looking at getting a monitor in the future, and this one fits the bill for me - cheaper than most of the other ones, includes a sun hood (yeah I know, simple things!), HDMI input (bargain), good size, and adjustable settings etc.

One thing that interests me is the Tally Light - I notice on the back of the monitor, there is what appears to be some sort of RJ45 connector (ethernet) - is this what controls the tally light?

If so, or even if not, how can you control the tally light simply? It'd help me certainly when I'm recording, as the only indicator normally is (other than on the front) on-screen on the 'built-on' LCD/EVF, which wouldn't be used if the monitor was in use.
