So, at the moment I have 2 24" monitors and I am wanting to connect my 40" TV to watch some movies on. I have one of my 24" connected via HDMI. Another using a HDMI to DVI converter and the 40" TV using again, the HDMI to DVI converter. For some reason, when I go to screen resolution and go to the monitor, it says you 'You must select Apply before making additional changes.

I click apply and this happens 'Unable to save display settings'.

I dont know if this should be in this section.
Is this a hardware issue?
Or a Operating System issue?

Depends on your CPU and motherboard.
A Sandy Bridge CPU can only support 2 monitors, and an Ivy Bridge CPU can support 3 monitors as long as 2 of them are DisplayPort - otherwise only 2.
Not sure about AMD, or Haswell.

If you're connecting the monitors via a GPU, it depends on the GPU - a low-performance one won't support 3 monitors.

A teacher, you say? :lol:  Well, we all learn something everyday. I've learnt a lot on this forum - mostly from being corrected :p 

And aiye, not much point in upgrading to Ivy from Sandy, I've heard :p

I have the radeon 7770, and it has 3 display adapters on the GPU, as well as a i5 3470

Best solution

The 7770 will not support 3 monitors - it is not powerful enough.
I believe only the 7950 onwards supports 3 monitors, at reasonable performance.

Sorry to be the bearer of bad news :( 

EDIT: The 3 display adapters on the 7770 are simply for connectivity to cater for the range of monitors that people own - it cannot use all 3 ports at once.
