Want to connect laptop to projector....

[kevhed72]

.....so should I just run a 2nd HDMI cable to the projector (with the first HDMI cable to the AVR), or should I run it through the AVR....and what cables / connections will I need?

Computer-> AVR->PJ.

Is the PJ your only display device? You would need two HDMI cables.

My setup is HTPC to AVR. AVR has two HDMI outs, one to LCD TV and another to the PJ. Does your laptop have HDMI?

PJ will be only display. The laptop has plenty of USB ports and 1 of those 7- pin plugs with the 2 screws (RS-232c connector?). The AVR's owner manual states:
"RS-232C connector
Use for connection to a PC for graphical output when
using Advanced MCACC or Full Band Phase Control."

I am assumming I can just connect the RS-232C connector from the laptop to the AVR, and then just run an HDMI cable from AVR to PJ (?)

RS-232 is a COM (communication) port, which doesn't have much to do with video output. You need either VGA (15-pin blue connector, analog), DVI (white connector, digital) or HDMI (digital). Of course, you can also use a yellow composite connector or S-video connector - both are analog, and won't give you more than 480i.

What is the laptop make and model#?

The 232 port is primarily for automation controls.

What Pioneer is saying is you can run MCACC and have a PC connected with their software installed via RS232 and see graphically what their room correction software did on the AVR.

The Pioneer software will query the AVR over the 232 and pull that data and show it to you graphically.

Pretty cool stuff actually like waterfall plots, phase, correction etc...

I'm sure that he wants to do exactly that... We have done some weird stuff with RS-232 including video runs at my previous job at NASA...
