    When I bought my Zenith HDTV (D36D53), I was not aware of 720p, and it seems that many of the new games on Xbox are supporting 720p, like Soul Calibur 2, Tony Hawk 4, and the new Grand Theft Auto Double Pack.

    I was wondering if there was some sort of reciever that I could purchase that could convert the 720p signal to 1080i? Any info would be greatly appreciated.

    On an interesting side note, my TV accepts a 600p SVGA res

    I'm sorry but I am not familiar with your tv, but both of my hdtv's do the conversion by themselves. Are you sure yours won't?

    Don't all Xbox games that support 720P also do 1080i?

    Some TVs can't take a 720p input.
    Some xbox games are 720p and not 1080i.

    So this can present a problem.

    Unfortunately the only solution I know is one of the very expensive scalers and they start at 1000 bucks.

    Yes, but most 720P fixed-pixel TV will accept both 720P and 1080I analog/digital signals and display them (converting everything to 720P if it isn't already).

    IMO all HDTVs should at least *accept* both signal types even if they convert one to the other. If they don't...it's bad design.

    My TV is kinda old (2001 manufacture date)

    John, you said that you can buy scalers to fix this problem? 1000 bucks is kinda steep, but I'm glad to hear there is a solution. Like any other new-technology based electronic item, the price will probably be cut down to 1/10th the price by the time it becomes a standard.

    Thanks for the replies. Anyone else care to share some info?

    Considering that 1) it takes more horsepower to run games at a higher static res like 1080i and 2) most games are high motion content with aliasing problems already, and 3) most quality games run at 60fps and I'm quite happy with 720p. I see most consumer sets as being able to only display 1080i as a flaw, not something to shoot for in regards to content, especially from video games or computers. Running at 1080i would just throw out half the vertical resolution of the 1080p frame. 1080p on the other hand is an entirely different matter. I agree, though, that all consumer sets should be able to cross convert 720p to 1080i.

    As stated earlier, the only way to cross convert the signals if your TV doesn't support them is with a stand alone scaler or PC card like the Holo3DGraph II and HD Aux input card. The combo will be in the $800 - $1000 range.

    Sean,

    Agreed.

    Hopefully the advent of digital 1080 devices based on LCOS, SXRD, and eventually DLP and other technologies will make 1080P a reality soon enough. As you say, 1080i for critical content like gaming is not a good solution.
