Well, sorry I think it is correct.
The web and many manufacturers give Gamut data on their monitors...including LCD/TFT/CRT
eg

As far as I am aware there is not a single monitor on the market that can display colours longer (ie redder) than a 620nm wavelength (this is the point at which red is displayed at in intensity of 255 with G, B at zero).
What a monitor tries to come up with and reality are invariably two very different colours. (unless the colour being displayed lies within the monitor's triangular gamut boundary)
But to keep it really simple.....I invite anyone to take look at the sun through a H-Alpha filter/scope. 652nm, viewed directly, appears as a *very* deep red to the human eye.
You can make H-Alpha look whatever colour you like on a monitor, but unless the monitor has a Red gamut boundary lower than 620nm (if you find one, let me know! ) the representation will be too orange.
