Oh well, here I attach proof of VGA working on my ASUS X550LDV with a ancient Samsung 800x600 VGA TV.
Here goes the ioreg as proof.
I dont know why it works but it does. As a side note I have been trying HDMI audio patches and they havent been working, although I do get HDMI video working.
Who said it couldn't be done?

Well, I only tried the "would-be" VGA connector types 1000/0100/0001 on existing connector numbers found in the vanilla Azul frame buffer (0105/0204/0306). I never tried a made-up connector number such as 0602 (or otherwise) for instance.
Agreed, Haswell GPUs do support VGA, just not in OS X as far as I'm concerned. And I never even loaded a Linux OS to check the IOReg when VGA output was used.
I'm sure that far more clever people than me would have found out by now if it were possible. Even if connector numbers that applied to SNB and Capri FB differ in Azul FB.
