Playback magazine received the following projector-related technical inquiry from one of its readers:
Comments: I am a big fan of your publication, although I wish it was still available in print form. I have a Dwin TV-3 projector that is just now in need of a new bulb. It will cost $500 to replace. I've also been seriously thinking about purchasing a new Bluray player, but I'd like to know a few things about compatibility first. The Dwin is only 720p, not 1080p capable. I was assured at the time that I bought it that it had an “HDCP compliant” DVI input. This was before HDMI entered the picture. Recently I've been told that I may run into problems with a DVI/HDMI conversation cable because not all Bluray players will complete the "handshake" with DVI inputs.
I'm inclined to buy a new bulb for the Dwin and settle for 720p resolution for a while, but I want to make sure a Bluray player will work properly with the Dwin. I'd hate to buy a new bulb and Bluray player and then discover that they won't work together without forcing a "downrez" to 480p. Would you please let me know whether I’ll have compatibility problems with this combination? If so, I’d rather save the bulb money and put it toward a new 1080p projector.
Also I can't seem to be able to contact Dwin either by phone or e-mail. I've left multiple messages for them using both, but have received no response. The dealer from whom I purchased the projector says they usually respond to an inquiry the following day, but
I've heard nothing from them. Perhaps they would respond to an inquiry from your publication?
Thanks in advance, Warren Poitras
We'll post the answers we've come up with in a separate response, below, but invite other forum participants to contribute help and insights on this one, as well.
