Which TV?

Olevia 37" 1080i for 550 or sharp 32" 720p for 599? Seems like a no brainer to go with the Olevia, but just wanna get a second opinion.

Also, does anyone know what time target opens on friday?

Isn't 1080i/720p the same thing. I mean, I think both TV's will do 1080i or 720p. I could be wrong though.
I know Olevia makes good stuff so I would probably tend to get that one also, especially since it's bigger. But Sharp is a better brand, so hopefully someone that has seen both of them will chime in.

All LCD and Plasma displays (except for Hitachi) are progressive displays. If they have 1920 x 1080 pixels, then they are "1080p" displays.
Some 1080p displays accept both 1080i and 1080p input signals, while some only accept 1080i input signals. If such a display accepts only 1080i, then it will de-interlace the 1920 x 1080 interlaced image into a 1920 x 1080 progressive image. If the display has a good de-interlacer, there will be no difference between a 1080p signal and a 1080i signal on the same display.
So to answer your question, no 720p and 1080i displays are not the same.

There is a significant difference between a 37" set and a 32" set, and given the prices, and the fact that, as XDRoX points out, Olevia makes good stuff, it makes good sense to go with the Olevia.

As for display, both sets have native resolution of 1366 x 768, so both will display at 720p (or more accurately, 768p).
Also, both will accept input signals of 1080i, so in the case of the OPs original question and the fact that both sets are 720p/768p native resolution, it is reasonable to say that 1080i/720p are the same thing and yes, both TV's will do 1080i or 720p/768p.

I have a 27 in Olevia which is less than a year old. IT is an OK display, but no where near the first tier products like Sharp, Panasonic, Samsung, etc. Our JVC LCD runs rings around it in picture quality and my older Panasonic TAU is also more pleasing to look at although it is a CRT based tv.

The rage about Olevia is a bit over done in my experience (ONLY IN MY EXPERIENCE so FLAME OFF). But screen size may be the deciding factor for you.

But Ed, what content/programing are you watching on the 27", what connections are you using?

Don't get me wrong I am not slamming the Olevia, it is simply not the pq of our other sets, but it was intended as a cheap second bedroom set. I notice the contrast is no where near as good as the JVC LCD and The Olevia also has a few peculiar quirks:

Sound volume usually runs around 1 or 2 (Not due to HD box)
Remote does not work well (some times fails to respond)
Have had a couple of lock ups where it failed to show a picture and had to be turned on and off again (not really very often though and not worth complaining to Olevia about).

All in all, it is just not the well honed performance of a first tier tv, but not bad for the money!!!

Ed in Sacramento, where my Olevia runs off a DishNet HD box using HDMI and is tuned to the Discovery Channel, History Channel, CNN News, PBS, and BBC (Ok some football).

Don't forget to add FUNAI to your list...:) Don't get a 32" as it is too small when you have to do WindowBox would make it a 27" view. 37" would give you 32" view for WindowBOX.

Your posts are making less and less sense. Since you list yourself as an A/V guru, please tell the professionals here just what is a WindowBOX.

I'm guessing he means 4:3???

I guess, like most people, I have grown tired of tipster's constant, absurd and for the most part stupid barrage of Funai crap!!
I'm about ready to block him.
So, much as I hate to admit that his use of the term is somewhat correct, it is:

Pillarbox: black bars on the sides of the screen. usually seen when SD program is displayed on a 16:9 set.

Letterbox: black bars on the top and bottom of screen, most often seen on 4:3 displays when widescreen program is displayed.

Windowbox: black bars on both the sides and the top/bottom, often seen when SD program is broadcast in HD and displayed on a 16:9 display.

I assume, as do you, that we know what he means. I just want the A/V guru to explain it so I know for sure what he means.

As to screen size:

While diagonal screen measurements mean the area is the same for all aspect ratios...

Because widescreens are stretched out in the horizontal plane (duhhh) a 32in 16:9 will not have as tall a picture or display text at the same apparent size as a 32in 4:3 set.

Simply said, if upgrading from an existing 4:3 set people might want to go up a couple of screen sizes if they want to keep talking heads the same height.

Would just hate to see someone mail order a 32in 16:9 and then realize that it is smaller in the vertical dimension than their old 4:3 32in tv.

Is that worthwhile pointing out guys?

Nonsense.

For a given diagonal screen size, the area of a 16:9 screen is about 11% less that that of a 4:3 screen.

Area of 32" 4:3 screen = 491.5 square inches

Area of 32" 16:9 screen = 437.6 square inches

OTOH, your comments regarding requiring a larger 16:9 screen size to obtain the same height of screen is valid. Multiply the 4:3 screen size by 11/9 to get the minimum 16:9 screen size with the same screen height. i.e. the 16:9 size has to be about 22% greater.

I thought the whole idea of a diagonal measurement is that the screen area can not be fibbed...guess was wrong!

Ed

The idea behind specifying the diagonal measurement was probably to make the screen sound larger. :) (Actually it was the diameter of the original CRT screens. They were circular).

The area of a 4:3 screen = width x height
= (0.8 x ScreenSize) x (0.6 x ScreenSize)
= 0.48 x ScreenSize^2

The area of a 16:9 screen = width x height
= (0.8716 x ScreenSize) x (0.4903 x ScreenSize)
= 0.4273 x ScreenSize^2
