Any ideas on why when I boot up the boot screen only shows up on my
second monitor ,,which is my tv ,, so if it is not on I see nothing .

Do I need to unplug it or is there something in the boot menu to change ?
MB is http://www.asus.com/Motherboards/P8Z77V_LX/

and both my main monitor and tv are plugged in to the graphics card.

It is not a big issue but ,,Why would the primary monitor not also show the boot screen ,
or the post info?

Switch the plugs on the video card. At boot time the BIOS does not know which monitor you have designated as primary. So it probably goes by the port.

A lot of monitor preferences are determined by the cables. I use (2) monitors on an Nvidia card.

I first plugged all in with HDMI cables, but my monitors (Asus VW246H) will not automatically power down on HDMI.

So now, I have one monitor on DVI, and the other on HDMI adapted to DVI. Now both monitors are on a digital feed, and auto-shut off.

My monitor #2 is to the left of monitor #1. The post screen comes up on #2 (DVI) and the W7 boot screen comes up on #2 (HDMI adapted to DVI)

Anyways, it appears (at least on my Nvidia card) that the DVI port takes priority over the HDMI port, at least on POST.

Xhi is correct, but you may want to vary the type (HDMI vs DVI) as well to see if that helps.
