Its pretty strange, and to tell the truth, I'm pretty baffled. Heres the situation. I recently changed out my Onkyo 805 in favor of an older B&K receiver that doesn't have a hdmi switching. Last night I hooked up the new receiver and finish setting up all my equiptment around it. I bought a monoprice 4 to 1 switcher to take over my switching duties. Now, the Dish Network box and Oppo dvd work fine, but for some reason, I am not getting any display from the ps3. I've moved it to another TV in the house, and it works fine, but it doesn't show up on my projector. I then bypassed the switcher, and still nothing. I really don't know where to go from here. I figure the next step is to call Sony or Infocus, but I was hoping someone might give me a little advice before I have to sit on the phone forever. Thanks in adavance.
