I'm wondering if it is possible to disable the Optoma 750 from constantly searching for input. Each time I put in a game, movie, or start an app like Hulu or Crunchyroll on my PS3, the Optoma searches for a HDMI signal for like 5 seconds. When playing a movie, this can happen a few times, such as when switching between the previews and also the main movie menu.
I disabled all of the inputs on the setup, so that only the HDMI input is enabled, yet this hasn't solved the issue.
Also, and this has happened probably a couple times in the past week, when I put in a 3D movie, the projector just displays a black screen. My default (no input) screen is blue, so the black screen indicates that the projector is receiving input, yet nothing appears on the screen. If I turn off the projector and turn it back on, it re-syncs the HDMI and the image appears, so it is most likely a projector issue. Is this something that others are experiencing (and a known issue) or is my projector is messed up?
