    Id like a good explanation from somebody who is well in the know. Im looking at the Vizio 37" LCD and it supports up to 1080i. Is that good enough?

    Will i notice a big difference?

    I figured he would se this eventually ...lol

    This TV brand has been talked about before a while ago. I think Compubolt got one if im not mistaken but its a good deal price wise.

    Its all about pixels. 1080p has twice as many pixels as 720p which is supposed to be similar to 1080i.

    The thing is though. To be able to view 1080p the broadcast has to be in 1080p. They're just coming out now with more 1080i and 720p broadcasts. But its still pretty limited.

    I'd go for a 1080p if your planning on hanging onto your t.v. for 10 years or more. But I'm not sure when stations will be able to broadcast in that format.

    but it is true. ONce you see 1080i or 720p or 1080p you'll never want to view any other format. Its amazing how clear it is.

    Jolt,
    1080p means 1080 "progressive"...1080i means 1080 "interlaced"

    the 1080 refers to the horizontal lines of resolution the set has...1,080...(720p = 720 lines of resolution...)

    Interlaced means that the lines are scanned or pulsed alternately so there are never more than 540 lines illuminated at one time (of course the lines are scanned or illuminated in milliseconds so your eye really cannot see the the flickering)
    Progressive means all 1,080 lines are scanned or illuminated at the same time...
    the more lines illuminated, the better the picture...
    (standard tv is 480i...standard DVD's are 480p...you can see the difference between standard tv and DVD as DVD provides a MUCH better picture...that is the difference between Progressive and Interlaced...

    Now, there are not currently (and may not be for 3 to 5 years) any 1080p broadcasts in the US, (HD programs in the US today are broadcast in either 720p or 1080i and most LCD's and Plasmas will receive both...ABC, ESPN and Fox broadcast in 720p which is better for sports and shows with lots of movement across the screen. CBS, NBC, HBO, Showtime, PBS and Discovery broadcast in 1080i which is better for movies and slower camera and screen movement) but all the new HD-DVD and Blu-Ray DVD's and players are 1080p (although I wouldn't touch one of those players with a 10 foot pole as they are having a format war similar to the Beta vs. VHS wars of the 70's and they are also having nightmares with the HDMI technology that must be present for the HD DVD/Blu-Ray units to work with your TV)...
    You can get a smokin deal on many 1080i TV's and they will be very useful for the foreseeable future...
    The Vizio's are decent but I have seen the MUCH better Panny's and Pio's for near the same price at Costco.com...
    (EC has a Panny...talk to him about the amazing "deep black" the set produces...the one weakness with Plasma and LCD tv's is reproducing Deep Black...most can only do a dark grey...the Panny;s have BY FAR the best deep black detail...Pio's and Hitachi are next)...

    I like my vizio, heck they have the same TV for 1500$ right now online at circity for thr 50inch. But seeing panny 50 inch for 2K, I woul d buy that in a heart beat. Good thing is, I know I can afford a new tv in 2 - 3 years once the burn in starts to set in. Plasma's/lcd's should be super cheap by the time I need a 1080p display.


    just a get HD tv, no matter what it is, it will change your life. :)

    Whats a panny. And good review o'rielly. Yah know your hdtv's.

    i think thats the question now. There just won't be any 1080p programming for years. IF I were boltjolt i'd get a fairly good 1080i/720p hdtv. And then in 5 years move up to a 1080p.

    Panny = Panasonic

    Only reason to have a 1080p right now is BluRay and HD-DVD's if movies are yer thing.

    So let me see if im getting this right.

    If i have a 1080i...i will never actually get 1080 out of it because it only illuminates 540 at a time? Wouldnt that mean that 720p is better?

    I read an article that said they couldnt tell the difference between 1080i & 1080p but of course thats one persons opinion....or two. Dont know how many took the challenge.....lol

    I also didnt see anything on costco.com in Panasonic and they dont have any pioneers.
    The Vizio is a great price for what you get in the size of the TV. The 32" is only $699....all the other brands are $999.

    I just wanted to know if 1080i is really lacking compared to 1080p.

    Thanks for the info. Later on ill probably get a DLP for the living room. I really like the pictures of the Mitsubishi's. Wish Costco had some that werent so big. I really only need a 50" for the living room....46" would even work fine.

    The Vizio's have a no burn in guarantee. Is this new since you bought yours?

    Best 42" TV on the market for under $4,000...
    http://www.costco.com/Browse/Product.aspx?Prodid=11165568&whse=BC&Ne=4000000&N=4001381&Mo=20&pos=0&No=3&Nr=P_CatalogName:BC&cat=3314&Ns=P_Price|1||P_SignDesc1&Sp=C&ec=&topnav=

    1080i is great for movies...720p for sports...some can see a bit more pixelizing/macroblocking or artifacts in 1080i...especially during really bright scenes like an explosion...not sure if you will notice it...both resolutions are exponentially better than standard 480i...

    Burn-in is not the problem it used to be with plasma as most if not all newer (last 3 years) plasmas have orbital pixel programs that decrease burn-in by 95%...but if you leave a static image on the screen for a couple hours, it will burn in...I'm not sure I would play video games on a Plasma...:lol:

    Judging by your football takes you clearly do not see well therefore the Hitachi shouldl suit you fine...




    :lol:


    Actually, the Hitachi set is an outstanding unit and that is a great price...I have a 42" Pro model Hitachi in office...

    Plasmas do have a great picture but ive been hearing they dont last nearly as long as the LCD which is why im leaning towards those. They tell me the picture fades faster than the LCD.

    Today's Plasmas have a 60,000 hours to half-life guarantee...
    That is about 12 years of watching 8 hours a day...the fade problem is a myth...
    If you are going to put the tv in a room that gets lots of sunlight or like to watch with a light on then get a LCD...if not, get a Plasma...

    That job at Best Buy is really starting to pay off. :icon_rofl:
    Isn't this about the time when you try to upsell Boltjolt the extended warranty?
