I'm getting nowhere with the AVS retards. I should have posted here to begin with. Let me know if you know anything about this (reply on this forum please!): http://www.avsforum.com/avs-vb/showthread.php?t=1035075

Your set is probably Plug and Pray. Have your tried just connecting it to see what happens?

I'm afraid to! I don't know if feeding it more bandwidth than it can handle will hurt it or not.

[MikeEby]

Plug and play is what the jibber jabber about the EDID was in the guys post. If your worried have it set to 800X600@HZ60 then fire it up, its under warranty.

Phil, have you tried some things and had problems? Why don't you just fire it up and see what happens? I'd do that first. Like Mike says, EDID might provide all the available resolutions and refresh rates the set will handle for you.

What are you worried about? It'll handle 1080p/60 - just don't go over that for starters. Besides, like Mike says, it's under warranty.

Anyway, if EDID fails, I'd try 1920x1080 @ 59.94 (standard 1080p timing) first and see what that looks like. Then, you could also try standard 1080i, or at worst, standard 720p/60. The last thing I'd try would be the 720p/72 - it would be a rare consumer display that would be capable of syncing to a non-standard refresh.

Hopefully, it has a "pixel-perfect" or "computer" mode so you can map the video signal pixel-for-pixel to the panel. Otherwise, you get to search for the "magic" combination - the perfect active/porch combination to eliminate overscan like so many CE displays have built-in.

Um..try 1080 24p.

It's a digital device.

You're confusing everyone with all this talk of interlacing and bandwidth, that's why you are getting no answers.

Oh, by the way, my plasma is an *interlaced* display, even though it has 1920x1080 pixels. Apparently this is due to limited bandwidth.

No, 24p will not flicker. Unlike a CRT display, which scans and refreshes according to the input signal, in a panel-based display, then panel and panel driver have their own native resolution and refresh. The display merely reformats any input signal to match the display. For instance, most digital displays have a 60hz native refresh - meaning the panel is updated 60 times per second, regardless of what you feed it. Some of the newer displays can handle 24p, meaning it will simply accept the input, but will judder because it's a 60hz display. Higher-end displays will actually re-sync the panel drive to match an even multiple of 24hz - as in 48hz or 72hz.

As for your particular display, it may be that if you feed it a 24p signal, that the display will automatically synch to an even multiple refresh... if you're lucky. If not, it will simply add 3/2 pulldown to display at 60hz, in which case there will probably be no advantage to running 24p.

Again, the display isn't technically interlaced. Only a scanning CRT is truly interlaced. From what I remember Dave saying, it sounded like Hitachi was doing some sort of pseudo-interlacing alternating-line update scheme. Since it may or MAY NOT be like interlacing, I wouldn't focus on that as far thinking about what sort of signal you want to input. I'd just do some tests - preferably with some motion tests and some resolution charts like on BD DVE, and see what looks best. Who knows, 1080/24p may look the best. 1080i/59.94 may look the best. 720p/59.94 may look the best (though I doubt it). Hell, until you try some stuff, it may not even handle anything besides those resolutions. It may not synch to ANY resolution at 72hz (that would be my suspicion) - it would be a rare CE display indeed that would synch to 72hz. Not even any consumer RPTV's I'm aware of would have synched to 72hz.

You're spoiled. Welcome to the world of consumer electronics. Now where did you put that G-70

You guys are helping me a lot! I never was into video until I bought a G70 6 or 7 years ago. Being very content with my G70, I've paid little attention to anything else. Hence my total ignorance about everything.

Quick update on my TV's performance. I haven't had much time to play around with it, but here's what I think of it so far:

The motion problems I saw at Circuit City, and especially at Best Buy, are something I see very little of on my plasma. Turns out it was just a demo loop problem. Speaking of bad demo loops (I don't think I've seen a good one yet), there's really no excuse for them. Certain HD material looks fantastic on my plasma. Common sense says that only this type of material should be used when creating demo loops. But that's not the case! I was in Wallmart today and made a quick glance at their HDTVs. There was SD video playing, and not even particularly good SD!

We should go into the demo loop business. These stores have no clue how to properly display HDTVs. No wonder HD has been so slow to catch on...

While my TV looks very nice at times, most of the time it's not very impressive. While there is occasional weirdness that I have no idea what it is or why it happens, the main problem is the low contrast ratio. My TV supposedly has a 10K:1 ratio, but it's pretty hard to believe that's true.

I've found that I get the best picture (not good, but best) by cranking up the brightness. If I run the brightness at lower levels, it not only crushes the blacks, but it crushes all of the colors as well. Bottom line: it doesn't have near enough contrast ratio. There's nothing that can be done to make it look good. You can't get even half way decent blacks without crushing the sh*t out of everything. The scenes that do manage to look good are always very bright scenes, where the lower ire poor performance isn't as noticeable.

It should display 24p as 24p....that's the whole point.

Otherwise it will accept STANDARD 1080i 60hz and convert to 1080p 60hz.


I assume you are using HDMI.
