    Daewoo 42" Widescreen Plasma EDTV Display Panel
    Model: DP-42SM

    is this tv a HDTV?

    PRODUCT FEATURES
    42" 16:9 plasma display panel with 480p native resolution (853 x 480 pixels) — accepts inputs in all major DTV formats (1080i, 720p, 480p and 480i), plus PC video

    Less than 3-1/4" deep — comes with table stand, or can be mounted on a wall (using an optional mounting kit)

    Wide viewing angles: 160 degrees (horizontal and vertical)

    Extremely high brightness (600 cd/m²) and contrast ratio (3000:1), with 5 selectable picture modes for excellent performance in a wide variety of lighting conditions

    3D digital comb filter enhances color purity of A/V and S-video input sources, reducing cross-color artifacts like dot crawl and moiré

    RS-232C serial port for future software upgrades and fast service diagnostics

    PC input (15-pin D-Sub), 2 component video inputs (1 wideband), 1 S-video input and 1 composite A/V input; 5 stereo audio inputs

    Picture-in-picture capability (PC on video)

    Dynamic Pixel Management system protects against screen burn-in by orbiting pixels within an assigned grid when an image remains static for too long

    Open air flow design ensures long plasma-cell life, and permits quiet operation with no cooling fan

    Built-in 16-watt hi-fi stereo audio system with flexible 5-band EQ, simulated surround and balance controls — can feed optional, matching 3-way Daewoo tower speakers or other external stereo speaker system (does not include built-in speakers)

    Includes simplified standard remote for intuitive operation

    I do believe that it will accept those signals. If they say it is an EDTV it will only display 480p. It most likely down-converts the signals for display.

    this is not a very good set. i have gone through 2 defective units and have decided on paying the extra for the samsung spn4235. it's a much better set.

    Any plasma that hovers aound $3k is only 480p, therefore not HDTV. They can usually accept an HD 720p/1080i signal but it will be downconverted to 480 lines of resolution. You get what you pay for with plasmas, why not grab a Sanyo Z2? [​IMG]

    "Normal" TV is 480 lines, interlaced, or 480i. This is sometimes now called "Standard Definition" or "SD".

    "Enhanced Definition" or "ED" is also 480 lines, but it's non-interlaced aka progressive scan, or 480p. This is what is stored on DVD. I'm sure that set would look great with DVDs, but...

    "HIGH Definition" or "HD/HDTV" is either 720 lines progressive (720p) or 1080 lines interlaced (1080i). Trying to show a picture with 1080 lines on a set with only 480 lines resolution.. well you can do the math.

    SD = 480i (good ol' TV)
    ED = 480p (DVDs and some broadcast TV stations)
    HD = 720p and 1080i

    Btw that Sanyo Z2 only has 720 lines. Personally for $3k I'd get a RPTV (CRT) and spend the extra cash on a couple dozen DVD discs, beer and popcorn... [​IMG]

    i think most people should actually view a tv with 480p native resolution displaying an hd signal. it's actually really good still. my brother has a rptv panasonic and his picture does not look as good as my plasma spn4235 samsung edtv plasma. i dont think hd is all that neccessary on plasma. atleast in the smaller sizes like 42"

    also, the daewoo plasma is pretty sucky. i suggest an akai from costco if your limited to cash flow. it's a better alternative.
