Yes CRT HDTVs are used a lot, but they are not multiscan. To get a multiscan monitor (like your PC uses) larger than a 19" would be costly, more costly than a large 1080p plasma.

My Westy 47" 1080P ( with overscan/scaling turned off ) looks awesome when connected to a 1080I/P source such as my laptop.

Rbinck, did you ever get yours working over VGA? I wish you could see it in person.

No I didn't yet. I haven't tried very hard because I use the DVI for my computer that I use the computer for computer stuff and the 1080p on that input is awesome. The other HTPC is just for HDTV playback and 1080i is fine for it. Actually as good as it gets.

I agree the 1:1 mapping really gives an outstanding picture.

Awesome. My laptop only has VGA out so that's what I use.

Yes. I know. I said that: "Buy a multiscan CRT (like your PC uses)."

It helps FattyPappy if you READ what I wrote.

Yes, of course, I would expect that any fool would know that "it is cheaper to build a 1366x768 NR FPD than it is to build a 1920x1080 FPD." But why build with a 1366 X 768 instead of using 1280 X 720: as I stated earlier the signal is feeding at 1280 X 720 so why not just use a 1280 X 720 NR display and avoid the scaling? Result: lower cost; higher PQ. Hard to conceive that 7% (768/720=1.07) higher resolution makes any sense especially since the final PQ is probably lost in scaling.

and Lee, if you're going to take another stab at this, please avoid any reference to 1920 as I intentionally left it out of the original question in (what now seems to have been a futile) attemt to avoide obfuscation.

Rbinck's answer was spot on as always, but before you vent any more on Lee, you need to realize your "720p" example is a major part of your confusion.

Although 720p (1280 x 720) is one of the ATSC standard formats in use, *very little* content is actually available in 720p. The vast majority of broadcast HD is 1080i (1920 x 1080) as are Hi-Def discs (HD DVD and Blu-Ray) and will look sharper on a 1366 x 768 display (even when downscaled) than on a 1280 x 720 display.

For that matter, try to find a 1280 x 720 display anymore. It won't be long before *all* LCD's (except the really small ones) are 1920 x 1080 and the only reason you still see lot of 1366 x 768 Plasma displays is it's still much more expensive to make a 1920 x 1080 Plasma (although now that all of the Plasma manufacturers are starting to make 1920 x 1080 PDP's, the price will start coming down as volume and yield increase).

P.S. Now that digtal re-scaling of video resolution is commonplace and cheap, multi-sync monitors are going to go away (as are CRT's I'm afraid--it's just so much easier to build, ship and warehouse flat-panel displays).

Hey troy, Im a little confused on what you put in your sig:

Quote:
HOME MEDIA MAGAZINE: Pricing from several disc manufacturers for 25,000 units of HD-DVDs and Blurays revealed a price differential of only 5-10 cents. (Lowest price: 90 cents versus 100 cents. Highest price: $1.45 versus $1.50.
I just wanted to get your take on the fact that there were over a Billion dvds sold last year alone. Now certainly the next gen formats are a long ways off from those kind of numbers, as is to be expected for competing with the most successful format in the history of man, and dvds have been out for a good decade. But your sig quote makes it sound like a five to ten cent production cost diffence is not significant, am I reading that right? Just for giggles, do the math on what a production savings of "ONLY" ten cents per disk is on one Billion disks. Oh, and try to keep in mind, thats only an annual savings, thats not a savings for the life of the format. Cause, again using dvd as a reference, a format could last ten years or more. See what Im getting at here?

Couldn't get the NXTbooks link to work. The questions to ask there are:

1) Were they comparing DL 30GB HD DVD to DL 50GB BD? If not, then the comparison doesn't mean anything.

2) Were they including Sony's disc pricing? If so, then it's bogus, as Sony is subsidizing disc costs (i.e. undercharging). They may also be subsidizing other disc manufacturers by lowering or waiving licensing fees.

Since nearly-all Hollywood movies are released to 30gig HD DVD, and 25 gig Bluray, that would be a more valid comparison. It would reflect the current state of the market. As to your question, you need to go ask the magazine's editor.

At the point where Hollywood is selling a billion discs, the price differential between Blu-ray and HD DVD will be 0 cents.

(Economy of scale.)

Nope . . . wrong again:

BD has released 178 25GB movies from a total of 297

Okay I was wrong. (shrug). No big deal.

I'm surprised to see BD50 in that list; I didn't think that would be necessary.

Huh?

At one point you were going on about how Blu-Ray was so much better than HD DVD because it had more capacity.

http://www.highdefforum.com/showthre...=37057&page=35

So now you agree with me, the capacity advantage doesn't matter in the real world and 25GB BD will look just as good as 30GB HD DVD? No need for 50GB BD then, right?

Ah well, the facts are, although there are a surprising number of SL 25GB BD movies out there and more to come (because studios found DL 25GB BD too expensive), which, BTW, really pulls the rug out from Blu-Ray claims of superiority, nonetheless nearly half the BD movies out there are 50GB.

You can't have it both ways. The only fair comparisons are either SL 15GB HD DVD with SL 25GB BD *or* DL 30GB HD DVD with DL 50GB BD. Anything else is apples and oranges.

If someone says, "Sorry I was wrong," I treat them as the best of friends. It's only those who refuse to admit they were wrong, that I take to task ("Where's your source/evidence?").

Yes I want the biggest disc possible, so I can store lots of data for my future PC projects.

I did not say that. Don't setup strawman arguments (put words into other people's mouths they did not say). Poor form.

Not as long as the studios keep using the exact-same VLC file for both discs. If you use the same file, of course there's no difference in the picture. But.....

If the Blu-ray consortium had any brains, they would encourage studios to create TWO files - one for HD and another for BD. Thus the Blu-ray would have a better picture (20 more gigabytes), and get glowing reviews for its increased quality.

Similar to how PS2 ports of Gamecube discs included better graphics or extra bonuses. (PS2=8.5 gig, GC=1.5 gig).

The extra disc space gave the PS2 an advantage.
