You have a regular monitor or do you plan to use the tv as one ?
Best to drive all graphics from the gpu if ports are available on it. In the presence of a discrete GPU, one rarely uses the mobo graphics slots.
I have 22inch Monitor, If GPU has HDMI is it necessary to buy mobo with HDMI ? ?
But Try to get one with HDMI, or atleast DVI.. VGA is quite old and obsolete
