    binentzeles ca 1080p e mai bun
    1080i e interlaced si sare peste imagini


    2. Why 1080p is theoretically better than 1080i
    1080i, the former king of the HDTV hill, actually boasts an identical 1,920x1,080 resolution but conveys the images in an interlaced format (the i in 1080i). In a tube-based television, otherwise known as a CRT, 1080i sources get "painted" on the screen sequentially: the odd-numbered lines of resolution appear on your screen first, followed by the even-numbered lines--all within 1/30 of a second. Progressive-scan formats such as 480p, 720p, and 1080p convey all of the lines of resolution sequentially in a single pass, which makes for a smoother, cleaner image, especially with sports and other motion-intensive content. As opposed to tubes, microdisplays (DLP, LCoS, and LCD rear-projection) and other fixed-pixel TVs, including plasma and LCD flat-panel, are inherently progressive in nature, so when the incoming source is interlaced, as 1080i is, they convert it to progressive scan for display.

    De obicei TV-urile cu 1080i au rezolutia verticala de max. 766 pixeli si sunt HDReady, cele ce "duc" 1080p au rezolutia verticala de 1080 si sunt FullReady.
    Clar 1080p este superior 1080i (dublu ca rezolutie vericala intr-un frame, la transmisie), dar mai conteaza si alti parametri la un TV interesanti.
    Sorry, nu am timp acum sa compar cele 2 TV-uri.

    nu functioneaza,am luat dvd-ul philips cu 1080p,am conectat la lcd samsung hd-ready prin hdmi si am ars un cd cu un clip de pe divx.com care spun ei ca este 1080p dar mie imi spune ca nu poate afisa rezolutia,gresesc undeva?
    la set-up-ul din dvd nu ma lasa sa selectez 1080p,pot intra pe 720p,1080i...
    am ars si un clip cu 720p si nici pe ala nu il pot vedea,de ce?

    Neo tu faci ceva gresit
    nu poti sa folosesti un dvdplayer cu upscaling la 1080p
    daca tv-ul este numai hdready
    dvd-player face upscaling si tv-ul face downscaling deoarece nu este fullhd

    si in plus
    exista diferite 1080p
    1080p/24 /30 /50 si /60


    dar de vazut filmul ar trebui oricum sa poti sa il vezi

    vezi sa nu fie cumva(Tipic la unele dvd-player) sa marga divx numai cu anumite tipuri de dvd(gen +r sau -r sau chiar numai rw(+ / -)

    IN plus uite cum sa faci Regiohack daca vrei sa il faci regiofree:

    1) Go to the Preference page in the Setup menu
    2) Press 1 3 8 9 3 1 on the keypad of the RC
    3) Options will be available to be selected
    4) done!

    Dupa ce m-am oprit din cele 5 minute de ris m-am gindit ca totusi e trist.

    Sunt doua aspecte:

    1. Rezolutia nativa a TV-ului. In cazul tau TV-ul are rezolutie nativa 1366x768 deci un pic peste 720p (1280x720). Indiferent ce alt semnal bagi in el, indiferent de la ce sursa, rezolutia afisata va fi maxim 1366x768.

    2. Sursa de semnal: Nici un player DVD pe lumea asta nu poate reda material encodat NATIV in 1080p sau 1080i sau chiar 720p. Pentru asta iti trebuie fie un Blu-Ray player fie un HD-DVD player.
    Ceea ce exista sunt playere DVD cu upscaling. Asta inseamna ca iti citesc un DVD in 576p (standardul PAL) si prin upscaling ajung cu semnalul de iesire in 1080p, insa materialul original ramine 576p.

    Toate DVD-urile PAL sunt 576p. Cele NTSC sunt 480p.

    Daca vrei 1080p intr-adevar, ti-am zis ce-ti trebuie: un TV Full HD si un player Blu-Ray sau HD-DVD (sau un PC de pe care sa redai material 1080p).

    Tu ai citit ce-am scris eu un pic mai sus?

    TV-ul are rezolutia nativa 1366x768. Mai mult de atit N-ARE CUM sa afiseze. Ca SUPORTA 1080i aia e altceva, inseamna ca poti baga in el semnal 1080i si ti-l va afisa insa nu la 1920x1080 ci cu downscaling la 1366x768.

    "this dvd suports 1080p at 50/60hs" inseamna exact ce ti-am zis: bagi un DVD in el si face upscaling la 1080p, insa n-are de unde saracul sa inventeze rezolutia lipsa. Dat fiind ca materialul original este 576p, o sa se vada un pic mai bine decit pe un DVD fara upscaling, insa nu va fi niciodata rezolutie nativa 1080p de genul Blu-Ray.

    In concluzie: cu acea combinatie de TV/DVD:
    - n-ai cum sa vezi 1080p
    - n-ai cum sa vezi 1080i
    - poti vedea 720p daca ai un player Blu-Ray sau HD-DVD
    - poti vedea un 576p cu playerul actual.
