October 2003 issue of "Stereophile Guide to Home Theater" has a warning on page 102 from Thomas J. Norton under the headline "Getting in Deep with DVI." It is included as part of a review of the iScan Ultra. He writes:


" We're seeing a variety of problems with this (DVI)interface in different combinations of source and display. Some combinations do work properly--for example the V Inc. DVD player into the Fujitsu P50XHA10U plasma. So it's too early to state definitely just where the blame might lie when they don't. In the meantime, a word to the wary. If you have your heart set on a DVI llink between your dispaly and a video processor, HD tuner or DVD player, make certain that the source will function properly with you specific video monitor or projector."


Put this comment together with what Randy Tomlinson had to say in the latest Perfect Vision about DVI and posts here over the past few weeks about DVI problems with the Panny PA2OU and the Zenith STB and I think we have to recognize a potentially big problem. Exactly how is one to make use of Thomas Norton's advice? You can hardly buy a new monitor that doesn't have a DVI. But I have not found a single store that was able to connect a STB with DVI output to a monitor with DVI input. There are going to be a lot of angry consumers out there when they discover that the "future proofing" feature they waited a year or more for does not work. In the meantime, the AVS Forum could serve the public well if we were able to compile a listing of compatible DVI devices.


Since the Panasonic 6UY and PA2OU are very popular on this site, perhaps we could begin with them. Can new owners confirm what STBs, DVD and video processors with DVI outputs work correctly with the Panny's? By correctly, I assume we mean that DVI output of 1080i, 720p 480p and 480i in 4:3 or 16:9 appear where they should with accurate colors etc. And if not, that you can easily adjust for it. (Tomlinson in Perfect Vision for one says you would be making a big mistake to purchase a monitor which did not allow you to adjust DVI signals since they are not uniform.)


How about the Fujitsu 42" and 50" plasmas which have had DVI for the better part of the past year? I recall that one or two AVS members said they had tried using DVI successfully, but don't recall with what devices. Surely there are more Fujitsu owners out there by now who have tried using DVI.

Malachy,

If you do a search for 'arungupta' and look at one of his posts you

will find a link in his sig that points to a "Practical Guide to DVI" or something,

and in that document is a "compatibility matrix" like you suggest.


And if anybody here has a DVI display and knows how it works or not

and it is not listed in arun's doc, please update the thread in

the DVD Players forum that is dedicated to his guide.

1. Zenith HD-SAT520 not compatible (left side of picture clipped)


2. Samsung HD931 compatible with DVI mode set to A, incompatible with DVI mode set to B (left side of picture clipped like SAT520)


Waiting to hear from Panasonic about these issues.

Hmmm, it's a shame the Panny's have these issues with DVI. Lot's

of folks have been waiting for the DVI input before buying.

Larry:

Thanks for pointing us to arungupta's "DVI-A Practical Guide." He deserves credit for beginning what is likely to be a bigger task than he perhaps imagined. It looks as if he has only begun to scratch the surface on publicizing compatibility issues. Perhaps what people should do is post a copy of their reports here on this forum about plasma and lcd DVI compatibility to arungupta's forum titled "DVI-A Practical Guide." It is part of the HDTV Hardware forum. I would include a link if I could figure out how. If he continues to update the guide, it could become extremely valuable. For now, it is still of limited use. I hope we and arungupta hear from more AVS members about their monitors and various DVI input devices.

I agree with the suggestion to keep posting about compatibility issues:


keep after the manufacturers to implement the fixes needed for DVI compatibility


many manufacturers will respond and fix issues once reported- keeping the pressure on them by posting problems will help

I encourage everyone to post their compatibility issues in the "DVI - A practical guide" thread. I am planning an update to the guide in 4-5 weeks that will have a significantly expanded section on DVI compatibility issues.


P.S. I am currently on a 4 week trip abroad, hence my limited participation in AVS forum.

Yep, yep, yep.


A year and a half ago I held off my plasma purchase for the promised DVI-capabilities of the Panny 4UY - which turned out to be a useless implementation of a DVI card in that model.
