Thought I would weigh in. I work at a video post production facility. If you can afford to get 1080p, by all means get that. No question. But honestly, I believe 1080i will become the "standard". The key won't be what the big networks have to do to convert over to HD standards. It is what the small affiliate stations have to do. 1080i would be the "easiest" to convert over since it is still based in the NTSC world.


Yes, does seem smart.

Also, 720p TV's will accept that signal and downconvert to 720p, and good 1080p tv's will deinterlace it.
 
Ok, can somebody define 1080p, 1080i and 720p? What's the difference?

Don't quote me on this but i think it goes something like this:

1080p - 1920x1080 native resolution for the TV. Means the monitor will do 480i, 480p, 720P, 1080i and 1080p. The "p" stands for progressive scan which is better then "i," which stand for interlaced. Progressive scan means that it draws all the lines on one pass of the screen. Interlaced means it draws the odd numbered lines ont he first pass then the even number on the second pass. It is usually a better picture if all lines are drawn per screen refresh.

1080i - 1366 x 768 native resolution. Means the monitor will do up to 1080i but no more.

720p - is again progressive scan and the max monitor resolution is[SIZE=-1] 1280x720.

I just recently purchased the Westinghouse LVM-37w3 which should be hear tomorrow. It is a 1080p monitor and i would suggest to anyone that if they are looking to get a TV soon needs to seriously consider getting a 1080p set just to future-proof themselves. Blue-Ray and HD-DVD are 1080p so if you plan on going to one of these formats then why cripple yourself now by buying a monitor that will not give you the best picture from those devices.

I've been looking to get a new HDTV to replace my 800x600 21" TV (almost HD but not quiet lol), but I have one question. I was of the understanding 1080i had 1080 vertical lines, with half (ever other) line being refreshed every frame. I would then think that a 1080i TV would have around 1920x1080 resolution, but most I see are 1366x768. Now wouldn't you lose some sharpness and quality squishing the 1080 lines down to 768 lines, or am is my knowledge of HDTVs incorrect?

You're both making a big mistake. Anything that wants to call itself an HDTV MUST accept and display 1080i input. What this means is that even a TV with 720p native resolution 1280x720, MUST accept and downscale 1080i to its display). This doesn't make it a 1080i set.

And yes, it'll be lower resolution than 1080i, but will still be much better than 480p.

To be a full resolution 1080i set you need the same resolution as 1080p, but somehow to lack the ability of displaying all the pixels in a progressive fashion, but instead only allowing interlaced signals where only half of the pixels are updated each frame.

The reason 720p and 1080i are the broadcast standards and 1080p is not is that these two schemes can both be transmitted in the same channel width as a regular SD NTSC signal. So they are backwards compatible to the old channel allocations.

Keep in mind that there is a difference between what a TV can understand and what it can accurately display.

I have a $129 15" LCD TV I'm going to mount to a wall in the kitchen. I've verified that I can watch 1080i Discover Channel HD content on it, as well as 1080i PBS shows. However, it's a 1024x768 panel, so clearly it's not showing 1080 lines of resolution. For use as a monitor, what matters is the actual resolution of the TV, as well as the resolution it'll accept from its inputs. For example, my older 37" Westinghouse accepts 1920x1080 on one of the DVI inputs, but only a lower res on the other. Be sure to check the (often online) manuals before purchase.

Here's an old shot of my Westinghouse connected to my mini:

 
How big is the TV, and how close will you be sitting to it when you use it?

I have a 50" 720p Sony TV, and I use it with my G4 from across the room. The text is readable at default size (12 point) and it's quite easy for me to iTunes, Safari, even Terminal.
 
Get the 42" Panny. It is only 1080i but, as previosly mentioned, you will only miss 1080p using blueray, hddvd, xbox, or ps3. And missing 1080p would really be minimal vs the expense. Go to an electronics store and find a 1080i tv next to a 1080p with the SAME input and stand back 5ft and then 10ft and see if you can really tell a difference. Also, at 42", the resolution loss for your computer monitor would be minimal vs a 32" 1080p.
 
Enjoy!

or better yet, wait for HDMI 1.3 and 1440p!

Thank you. I looked up mine and it's a 1080i. That'll do me fine for now. ;)

I'll be seating about 5-10 feet away. 10 feet rarely though. Mostly 5 feet ish...
 
Has anyone connected a mini (G4 or Intel) to a 1080p TV?
That is a TV that can do 1920x1080 natively. Not CRT based. LCD, DLP, LCOS or plasma only.

This is all making me curious about iTV.

Yes, I have mine set up that way. Look up a few posts.
 
I guess I should read more carefully. I thought it was a 1280x768 LCD.
How do movies look? comparing DVD player to mini?
Is mini a G4?
What about high def? tried an trailer?
 
HD DVD is not 1080p.

Have a look at the new Toshiba HD DVD player. The HDAXA2, I think? It's going to do 1080p. :)

Also, people should stop misunderstanding 1080i. Just because your set can take it , doesn't mean it is. For instance...42" panasonic plasma (th42px6/60/600) is NOT 1080i. It is 720p. It's resolution is 1366x768. It takes 1080i because some stations like cbs, nbc, and occasionally discovery hd will broadcast 1080i.

Like I've said in countless threads, a 1080i set will have a strange resolution like 1024x1080 (see: http://www.hitachi.us/tv/browse/plasma/plasma/42hds69.shtml)
