Question about Optoma Projector Multimedia Projector
Hello, I hope you can help me with a problem that I have been having with an Infocus LP640 projector. I have been trying to get it to work at 1080p resolution with a Playstation3 and a HP dv 9600 laptop that has a HDMI connector. I am using a standard HDMI gold plated 3 ft cable and an M1 to HDMI adapter shown in the attached picture. Everything works fine at 1080i but as soon as I try 1080p the projector will show a signal out of range message. If I hit some of the remote?s buttons the image will appear but distorted, out of scale, and bad quality, also I am not able to make any adjustments to the projector since the menus are not available for changes in the projector?s setup display. When I bought this projector the specifications in my manual show that it is 1080p capable but if you go to the Infocus website now it shows it is only 1080i compatible. It also says that this projector is not HDCP compatible. I have remote router to laptop and an desktop I have the laptop to VGS and the desktop to DVI inputs, only get a signal through VGS input. Why will the DVI not work?
Hello, The LP640 will NOT down-convert 1080p
1080i is the max it can down-convert.
As far as the DIGI input, it is not DVI... It's a proprietary
InFocus format they call M1-D P&D and is NOT HDCP compatible. I have several LP640 manuals, some quite old and none of them claim that 1080p is a valid resolution. interesting that your manual says it is... very odd indeed.
