Pioneer Elite VSX-84TXsi--- 4 HDMI inputs!

Richard, right now my system is operating perfectly...I just can't switch the projectors...(It makes no sense). 32 ft is no problem at all. I have gone 60....but to me, that is pushing it. I have found that with HDMI 32 ft is about as far as you should go with good thick expensive cables...I get mine from http://www.pacificcable.com/ ....DVI is a differnt story...You cannot go beyond 20ft without problems in most cases.

From experience that means your system is only working. Otherwise you would be able to switch out the projectors.

As for distance DVI is about 32 feet with properly constructed cables and HDMI adds another 10-20 feet, would have to look that one up.

The difference in cable construction and specs show up as you increase the length. The link provides the perfect example of what can happen.

Richard, both projectors are connected to the exact same brand of 32ft cable (and both of these 32ft cables are connected to the same switcher)...So there should be no reason I couldn't swap them out. As I said..."it makes no sense"...I just wanted to let folks know how finicky HDMI can be....BTW, Both projectors use the same bulb, so I decided to just swap bulbs....

I think the problem is in the 700U projector itself...(They must have made some improvement in the 900U as to it's sensitivity to the signal)...My cables are definately not too long...When I get the Optoma HD81 projector I will sell the 700U so that should end my problem.

If the 32' meets specs you are correct. So what brand and model are using for that run?

I use these cables...(the picture is incorrect), but the specs are correct I believe...I called them when I got the cables and they said they no longer send the skinny ones....They sent me the thicker ones cause they were better for longer runs. (My cables are twice as thick as the one you see in that picture...FYI.

It should work. If you are curious take the projector and hook it up with a short run like a 1-2 meter system componet cable. If it passes it's the cable regardless of what they say. If it does not then it is the display.

Richard...thank God this is all going to be moot. I have sent back the 4X2 Switcher for a refund and am applying the bucks towards the new Pioneer Elite Receiver with 4 HDMI inputs and one output. I have been doing tests going straight from the receiver to the projectors and I am able to swap them that way. (So it had to have something to do with the extra draw from the switcher). With the new setup I will be able to be sure all 4 HDMI inputs will play DD+ into the receiver. The Video coming out of the receivers HDMI output can be sent to an HDMI splitter and then to the projectors with no worries of the DD+ audio anymore. (problem solved)...

Sounds like the switcher was having a handshake problem with the projector... Forgot about your switcher. Good troubleshooting!

BTW

HDMI cabling manufacturing could not use the same old techniques used for analog cable manufacturing, the lenght of all the pieces of that HDMI wire has to be exactly equal, or the difference in lenght could produce the fast signal transported on that wire to have different arrival time at the other end, which would have an effect on the image.

Interestingly enough, a superthick cable that some people could prefer for transporting a signal, could produce a problem as HDMI transport if manufacted incorrectly. The super thickness could cause the ends of each piece not to be exactly equal in length when they arrive at the plug. Equipment did not have anything to do with making the signal worst in this case. Some people could have thought a thicker wire could be better in all the cases, ignoring construction, quality of material, plugs, etc.

Hi guys, Sorry for not being around more. I had a bit of trouble logging in so I reset my password and now all seems to be well. Jeff, I am freaking out! I just bought the VSX-74TXvi with 2 HDMI inputs and now they come out with the 4 input model!!!!

Dang it! Anybody interested in buying my almost new 74TXVi? I'll let it go for 800.00 bucks. I want the new 84TXsi as well. I don't want to mess around with these switchers anymore. BTW, I did decide to go with the Panasonic PTAE-900U projector and I couldn't be happier! I like the idea you came up with having an electric screen come down over the dresser mirror in your bedroom! Now I just have to convince my wife!,,,
