I upgraded from Sanyo Plv z1080hd and epson amazes me.
Tried 2d to3d conversion, it's better than my Samsung plasma tv d7000 59 inch
The good thing is I can use my Samsung glasses for epson too
I have posted many times on this forum about HDMI problems. You can search my name and find some info on HDMI. The 40' cable is probably the culprit. Move your projector near your equipment or vice versa whichever is easier and test the system with short cables 2 meter or less. If it works you have a cabling problem, plain and simple. I don't care if it works with one item and not the other, that is analog thinking and there is a lot more going on with digital signaling and you won't find the root of the problem that way. You need to find out if you have a cabling problem or an equipment problem and the easiest way to do that without test equipment is test with short cables.
When one component works and another doesn't does not mean the cable is Ok. I'm sure the cable is fine as far as not having a short or loose wire, it is just not capable of the bandwidth you are using. With HDMI you have to look at the whole circuit and there is enough variability between equipment to make it work with one device and not another. That doesn't mean the equipment is bad, just one can handle something a little more out of spec than the other. In other words you got lucky. I know it is a bit of a pain to get all the equipment together but it saves a lot of tail chasing once you rule out whether it is the equipment or the cable. If it is the cable there are solutions to solve it. If it is the equipment then it is time to go through all your settings and possibly replace one of your components. But, that is a little more tricky to figure which component is causing the problem. With HDMI it is often not the one you think. Receivers get blamed a lot and Yamaha is one of the VERY few companies that actually submits their products for HDMI/HDCP testing.
But, do the test with short cables and let us know what happens. Sometimes it can be a problem with one of the short cables but this is a lot less likely. For someone without test equipment this is the best they can do to start the diagnostic process.
Well, the first thing to check is some of the settings of the equipment. I'm not familiar with the iView so I don't know it specifically. On the Yamaha set everything to pass through and in the advanced menu set monitor check to skip.
If the iView has deep color or higher than 8 bit (24 bit) than turn those off. Turn off RGB and us 4:2:2 setting if it has one. Turn off CEC on all devices.
Try the iView at lower resolutions first. try 480i/p then 720p. Do any of the resolutions work?
Do this testing with short cables to rule out any other variables.
Magnavox, Channel Master and Tivo make DVR OTA Tuners. The Tivo charges a monthly fee though.
