    You need to read the specs and the reviews for the various models you are considering. The Faroudja DCDi is a good deinterlacer. Performance varies will additional frame memory and feature licensing. You need to read the advanced reviews to get this information.

  2. Before i focus on the positives i also need to be concerned about the negatives.

    I've come across concepts like bleeding, clouding, ghosting, juddering, image retention, break-in, burn-in and some others.

    Can we quickly compile a complete list with such issues so that i can research the models i have in mind if they experience these things, and also to check after i purchase problems it might be susceptible in and possible return it?

    So what other concepts such as the ones mentioned, should i be concerned about?

    Add analog/DVB PAL upscale quality since you mostly receive standard def.

  4. I'm thinking I should go for a budget tv set so I can save money.

    There's this plasma lg at 42inches vut it has a resolution of 1024x768.

    Since it's wide it
    must have a non square pixel ratio but what dies this mean?

    That it will display 4/3 in full and 16/9 with black bars at the top Ns bottom?

  5. Do NOT buy any HDTV with a 1024x768 or 1024x720 native resolution, the pixels are not square. 1280x720 and 1365x768 are acceptable.

    That LG is probably 2-3 years old, they only sell 1365x768 and 1920x1080 now.

    No, it will display the picture the same shape as any other HDTV. It will just have less resolution on screen than a 1920x1080, or 1366x768 HDTV.

    If you are going for a low end plasma, get the current models. Prices have been dropping and performance has improved. Plasmas have gained resolution while lowering power consumption. SD performance will be better for the current models.

    For game/computer use at close distance, get at least 1366x768 display resolution.

  8. The lower end plasma have either this weird 4/3 ar or 1366x768 which i'd rather avoid.

    I still dont get how they can display 16/9 as wide?since the original ar is 4/3 displaying a 16/9 format will produce blavk bars i reckon.

    Anyway i'd much rather avoid having anything to do with a 4/3 resolution on a wide format screen.

    An additional questions is, will a 720p screen (I mean an absolute 1280x720) display 720p video signal better than 1366x769 and 1920x1080?

    Happy new years everyone. Cherrish the ones you love and live a happy and prosper life full of health and whatever it is you wish.

    1280x720 HDTVs are nearly non-existent. And if you find one it will probably not have pixel-for-pixel mapping when given a 1280x720 signal. It will upscale to about 1344x756 and display the inner 1280x720 -- to simulate overscan. If it has a VGA port it might give you pixel-for-pixel mapping with that. So generally, no, a 1280x720 HDTV will not give you a better picture than a 1366x768 HDTV with a 1280x720 source.

    The 1024x768 monitor displays 16x9 but the pixels are 4x3 wide.

    Few 1280x720p displays exist. If they did they would still upscale 3-7% for overscan, just like few 1920x1080 native displays actually show 1920x1080 except in special non-overscan modes (e.g. Samsung "just scan" mode).

  11. I know about overscan, i just thought that TV's used 1:1 pixel mapping. If a TV is FullHD 1080p and you need to see a 1080p blu ray disc, then why should it overscan and then position to 1080p? That's absurd, i dont see any reason for it, since it can account for every pixel of the source...
    Quote Quote  
  12. Manufacturers make TVs overscan because broadcasters often have junk at the edges of the frame. Broacasters don't worry about junk at the edges of the frame because they know TVs overscan and nobody will see it. It's a vicious circle, There's no way out.

  13. Thing is I don't even care for tv beoadcasting since I only Need to project my own media so I fall victim of this crappy overscan feature

    how can I make sure that a certain unit does 1:1 pixel mapping?

  14. Samsung calls it "just scan" other manufacturers call it by different names. You'll have to find out what those names are and which models have the feature.

  15. 1:1 pixel mapping is usually on LCD HDTV's. Toshiba, LG and Samsung have the feature.

  16. Sony LCDs have pixel-for-pixel mapping options too. And some 1080p plasmas now have the option.

    Even my Samsung 56" 1080p DLP has the "just scan" function

    Just do your research on the model you are considering. Many LCD/Plasmas are fixed to overscan.

  19. Until i get my new TV Monitor i have been playing on my PC Monitor.

    I enabled 720p video signal from my PS3 (Default is 576p) but it upscale to the full extent of my PC Monitor and i'm concerned for distortion.

    PC Monitor AR is 1680x1050 which makes it 16/10. Shouldnt i have a little portion of black bars at the top and bottom in order to display 720p correctly?

    Does my PC monitor have an internal upscaler and handles the 720p and uspacles it to full screen?

    Some monitors scale whatever input they get to full screen.

    Yes but a computer monitor has a simple upscaler. That is why you feed it native resolution it you want a sharp picture.

    It simply converts 16x9 1280x720 to 16x10 1680x1050 thereby stretching pixels from square to tall.

    The only way to get them square again is to adjust vertical size on your monitor any time you want to watch video.

    An LCD-TV will have a more intellegent scaler that maintains aspect ratio through use of letterbox. Depending on the model purchased, an LCD-TV will also have a more sophisticated interpolating upscaler with deinterlace and inverse telecine features.

  22. The PC Monitor does have options to stretch horizontal and vertical sizes but they appear greyed out and i cant use them.

    Although on the menu osd it does display the incoming signal as 1280x720. So the only thing for sure is that it understands what res the incoming signal is.

    Now i got to find a way to allow it to display correctly.

    Any idea as to why it wont let me touch the horizontal and vertical posish?

    Yep that's a good thought. i dont have a VGA cable though for my PS3 to see if that is indeed the case.

    Do you guys play any video games? In comparison with video playback, video signal coming from games is dynamic. Meaning that polygons are generated according to how the game plays out, and that's possible for various resolutions without having distortions.

    That's why in most PC games you can choose amongst many common resolution keeping in mind the power of your graphic's card and such.

    I dont know if the same applies to console gaming. I am not sure if they are supposed to have a fixed resolution (ie 720p or 1080p max) or if they can adapt to various other resolutions and generate environments without AR distortions.

    Most XBox360 or PS3 games are native 720p or less. The HD output resolutions are hardware scaled in the console.

  27. But are the environments re-generated in better quality or is it scaled as a picture like the TV would scale a lesser image to its native?

    That's what i'm trying hard to understand.

  28. Many games are rendered at lower resolution then the 2d image is upscaled by the display hardware. This is because the 3d chips don't have enough power to render very large frames.
    Quote Quote  
  29. How do you know though, for each game what stands?

    Cause for the time being i have set my playstation to output 1080p. If the graphics arent being rendered in that resolution maybe it could be better to set ps3 upscale to 720p, so the TV will handle upscaling the image to native 1080p.

  30. I just bought this monitor i like it
    i'm not a gamer but it would probably suit your need as it's got a 2ms response time. DVi & HDMi, 16/9, Full HD 1920x1080p

    This review regarding the previous model helped me a lot.
