no signal from computer to H7530d

Have been using my computer connected to an H7530 for a couple years now.  Was using a DVI to HDMI cable.

 

Also have the cable tv, and BD player hooked up to the projector.  Switching is done thru a 3-way hdmi switch.

 

The BD plays fine at all resolutions, the Cable TV works fine with all resolutions, but starting about 2 weeks ago, when  I start the computer, I get "no signal"

 

If I hook the computer back up to my 24inch lcd, the monitor works fine, no matter what cables I use to connect it.

 

I hooked up the computer directly to the projector with the DVI to HDMI, and get no signal

 

I got a 6ft hdmi cable, and bypassed the 3way switch with a direct connection from the computer HDMI  to the projector HDMI with no luck.

 

I got my previous computer out, and hooked it up directly to the projector with an DVI on the computer end to HDMI on the projector end, and got "no signal"  This other computer does not have HDMI on the video card, but it does have an S-Video, so hooked up the computer to the projector with an S-Video, and got a signal, but S-video does not support 1080p.

 

Neither computers have video cards with VGA out, so could not try that out.

 

I am pretty much at a loss at what could be going on here.  Everything works fine with the projector except the 2 computers I have here.

 

I guess it could be a power issue on the computer end, but the lcd monitor still works, and we are still talking about 2 computers that can not be hooked up to the projector.

I sympathize with complicated configuration issues.

 

Basically, other devices can send HDMI to the projector and work fine. 

The computers that are hooked up are not able to do so.

 

If other devices are sending HDMI and it's working, that would indicate that the HDMI port is operating properly.

You also note that the S-Video port works as well.

 

Other than a configuration change, or Windows Update, I'm unsure why you would suddenly be unable to send HDMI signals only from the computers and everything else still work.
