Why aren't HD plasmas naturally 16:9?

    Most HD plasmas are 1024x768. A more natural resolution for the shape of the screen would obviously be 1280x720.

    Why are the panels made 1024x768? I read that it often gives people problems trying to display a PC picture properly. A friend of mine with an ALIS panel (1024x1024) has this problem too.

    Why make the panels like this when 1280x720 would also be a much better fit for 720 line output as well (no need to add lines)?

    The plasmas are phsically 16:9 but their native resolutions are not, resulting in rectangular pixels?

    1366x768 plasma have 16:9 physical size and native resolution. :)

    Many displays come from PC world where 16:10 is more common ratio -- you may notice that many LCD are actually physically 16:10 (but advertised as 16:9) as are their resolution.

    Historically panels were driven from PCs for commercial use, long before HD resolutions appeared -- hence use of 1280x768 rather than 1280x720.

    I know the screens are 16:9 in shape the question was why do they have resolutions that are 4:3? As you say this results in rectangular pixels which seems odd to me. I know there will be some reason (almost certainly economic) but wondered what the reason is...

    As above "Historically panels were driven from PCs for commercial use, long before HD resolutions appeared -- hence use of 1280x768 rather than 1280x720."

    Which is why other display technologies like VP and RP, that were developed for TV and Home Cinema applications from the start, can easily be found in 1280x720 resolutions (and with multimedia connectivity rather than PC connectivity btw), while plasma's have been entering the HC arena at a later stage, coming from a PC monitor/Biz' application...

    StooMonster forgive me if I'm being thick but HD plasmas are generally 1024x768 not 1280x768 - is that what you meant to type?

    Pioneer's 50" models are 1280x768, and the 43" ones are 1024x768.

    http://www.ivojo.co.uk/plasma.htm will give you a nice table.

    You could be right, I may have been thinking about LCD.

    Either way, it's because they were computer displays first and home entertainment devices second; that's the economics.
