Default [Q] HDMI and VGA Connections

Hi everyone... This is my first post... So I hope everyone will be lenient if I do not things right...
I have asked this question on many forums and asked many people but it does not seem to interest many people... Yet it is of paramount importance to me... I connect my phone to TVs and video projectors every day for my work... So far, this has only been possible on TW 4.1.2 roms... Does anybody know if it it still possible with the new samsung kitkat 4.4.2 stock roms? If I can upgrade? Many thanks for your response....!
