You're using all the xrandr functions regardless if USING_XRANDR is defined.
No point in having the define if you ignore it like that.

It's not even that -- MythContext unconditionally included it, but libmyth.pro
conditionally compiled it.

Extra work? You'd be replacing the 'gContext->displayRes' with
'GetDisplayRes()'. No extra work.

It's not a question of being a member, it's a question of it being a public
member. It _should_ be private.

I'm not talking about the data of the DisplayRes class, I'm talking about
having a member variable be visible in the public MythContext for absolutely
no reason.

The context is global. Not knowing anything about it is rather pointless.

'if' without a space after it is horribly annoying. 'if' is not a function.
The displayres class is full of tabs as well.
