Dear AV Gurus,

I hope someone here can provide me some help. I had a BenQ PB6200 which died on me. I was told the PS is most likely the culprit. Anyway, I looked around on Craiglist, and found a BenQ PE8700 ( for sale. PO hardly used it and unit was in excellent condition.

Quote taken from
"The PE8700 connector panel gives you three inputs in the "video group" and two in the "graphic group." The video group consists of one composite RCA, one S-video, and one set of three component RCAs for component interlaced input (no 480p available on this input). The graphic group gives you one DVI-I connector and a set of 5 BNCs for component interlaced, component progressive, HDTV, and computer input."

So, I have a DVI-D to HDMI transceiver. I tested the connection to my Dish receiver. Initially, the projector would not detect the signal when both units are on. However, when I re-seat the HDMI from the back of the Dish receiver, the projector detects the signal on the DVI.

I then take the setup one step further. I connect the Dish receiver to one of the HDMI port on the back of the receiver, and connect another HDMI cable from the receiver's HDMI out to the projector. I turn everything on, but I do not get any output on the screen. I tried reseating the HDMI cables, and still no luck. FYI, I did switch the receiver to the correct output channel...

I know the DVI connector on the PE8700 will only accept up to XGA resolution, but I am not sure about the signaling frequency on the XGA. I assume since DVI is a subset of HDMI, and both are digital, the transceiver should work. Any help or advice is much appreciated...

Thank you.
