As the title states, I am debating whether or not to purchase a new toshiba 1080p hd-dvd player. I currently have the Toshiba HD-A1 connected to a 71 inch Samsung 1080p DLP which has been calibrated by UMR, and I am on the fence as to whether or not I NEED the 1080p or if I should stick with 1080i. Will the difference be noticeable on a 71 inch set? thanks in advance

Well, if you feed your set 1080p60 from a PC, like for World of Warcraft, it makes a difference..

/gloat

But yeah, for cinema content it doesn't matter. Unless Discovery or IMAX start putting out 1080p60 discs!

(if there's a 1080p60 Yule Log I'm SOO THERE... Or 1080p60 fishtank...)

Does your tv accept 1080p?

Does it pass the 1080i deinterlace tests (full resolution on 1080i)?

Just enjoy HD in whatever form you can (Sat, Cable, D-VHS, OTA, HD DVD, or BD).

It's the JVC 56FN97, and it syncs 1080p with a bit of overscan (1836x1024 is the exact res )

Good Q, I still need to pick up a high-def player, since I'm upconverting everything right now but XBox 360 and PC.... Both look gorgeous and no lag whatsoever.

That article was great info, but I'm still confused. A couple months ago I just bought the new 2007 Samsung model LN-T3253H. It is a 1080i TV, not 1080p. Does this mean there wouldn't have been a difference if I bought the 1080p model for HD DVD's?

The 3253 is actually 720p, actually native resolution is 1366x768.
All digital displays are progressive, and convert all incoming signals to their native resolution.
The 1080i on the display means that it will accept a 1080i signal of 1920x1080i and convert it to the displays native resolution of 1366x768p.

It matters if your TV accepts 1080p/24..

See how your Blu-Ray movies stack up. Visit the Blu-Ray Tier Thread Today.

1080p will look exactly the same as 1080i on a TV that excepts both formats. Why? Same exact number of pixels. And if your HDTV is a flat panel, it's displaying both formats progressively anyway. Read Myth Number 2, here: http://www.popularmechanics.com/tech...31.html?page=3

This is not always true. Some displays will look worse with 1080p if they handle it incorrectly. Remember these things are just computers with different I/O and the source or display can have software errors in them. It is also possible for 1080p to look better because you are bypassing poor processing in a display. In most cases they will look the same, but the only way to know is to test.

Since you are here, and this is my thread, you did a WONDERFUL job calibrating my set! It is night and day especially when running my xbox 360 games

Well, the original poster says he has a Samsung 1080p DLP. That means he likely has an HL-S or HL-T model and those are well known to de-interlace properly. I know because I have the HL-S5687 and my site does de-interlace properly.

But in general, it's true that it depends on how well the TV processes the 1080i signal.

Thanks for the report. I've included it in the list of owner's reports that is linked at the bottom of my post.

Because you didn't say much in your report, I assumed that your TV is the HL-S7178, but it might be a HL-R model. I also assumed that UMR didn't calibrate your audio.

It's ok to use the edit button to add more information about your equipment, and to describe what you like most about UMR's calibration results.

My eyes can perceive only subtle differences between 1080i vs 1080p.
Once I was able to spot slight additional details in the background and a faithful color rendition on the skin tones in a bigger screen at a distance of about 3-5 ft. But 1080p won't be deal breaker. May be 1080p/24Hz combination would eliminate the common motion artifacts observed with non-1080p/24Hz signals.
