Plasma TVs for Video Games?

moonboy asks: "As plasma televisions continue to come down in price (Gateway even has a 42" available for $2999) I'm considering purchasing one. Has anyone here had any experience with these and particularly playing games on them? I'm thinking about both console and PC games however, I'm concerned about refresh and resolution. How do they compare?"

    It shouldn't, most plasmas are progressive scan and 1080i- hence they should refresh every pixel VERY quickly. Progressive Scan means that the entire screen is redrawn in a certain time interval not just the pixels that change. 1080i is just a form of HDTV.

    1. Re:No Problem by Cecil · · Score: 5, Informative

      Uh. 1080i and progressive scan are mutually exclusive. The 'i' in 1080i stands for 'interlaced' which is the opposite of progressive scan.

      720p is a progressive scan HDTV format with 720 lines. 1080i is an interlaced HDTV format with 1080 lines.

      Which one is better is debatable, but knowing they are seperate makes your post nonsensical, and that's besides the fact that neither of these directly relate to the speed of the refresh rate, only the resolution of the picture.

      What were you trying to say?

      Progressive or interlaced has nothing to do with refresh rate[1]. A display be could called progressive even if its refresh rate were 1 frame per second[2]. In the same way, an interlaced display could display 200 fields per second and therefore be able to display 100 frames per second but it would still be interlaced. That's because term "interlaced" means that every other line is refreshed at once (all the odd lines or all the even lines), usually from the top to bottom and then the other lines are refreshed in the same way. Interlaced does not mean that only pixels that don't change are refreshed. With slow enough phosphor interlaced displays look good with static images but they are inferior to progressive displays when there's any movement. In addition, slow phosphor decreases image quality during movement (like extra motion blur effect without an option to toggle it off).

      If specs of plasma or LCD display say that it supports progressive inputs it doesn't mean that it can display the full progressive stream but simply that it can display some kind of image. For example, many new LCD projectors allow progressive VGA signals with 90kHz horizontal sync and 85Hz vertical sync. You can be pretty sure that LCD display isn't able to refresh its pixels at that rate but the spec is only saying that it can sync to the input data. If the display cannot keep up with the data some intermediate pixel values will be skipped and the end result can be pretty close to slow phosphor effects - in the best case.

      That being said, plasma displays should be plenty fast for progressive HDTV signals but that's only because HDTV image really isn't that high quality. Any 19" CRT monitor can display much higher resolutions with higher refresh rates than HDTV setup. Don't expect to be able to get high quality image from PC. I suggest previewing the cheapest plasma displays before buying, though. They might have used low quality components to reduce price.

      [1] Except that with low quality components it's easier to do a viewable interlaced display than a progressive display.
      [2] For example, a slide projector is progressive display.

  2. Progressive scan vs. interlaced by HeroicAutobot · · Score: 3, Informative
    Actually, 1080i is interlaced mode, which means that every other line is drawn on each scan.

    I don't know of any TVs that support 1080p, which is what your describing. (Not that they don't exist.)

    Usually 720p is the highest progressive scan available.

    There's a fairly good description of progressive vs. interlaced at Panasonic, but it concentrates on 480p vs. 480i. (The basic idea is the same though.)

      A lot of mid-high to high end projectors designed for home theater support 1080p, but note that (I beleve I am correct on this but it's possible I misuderstood something), you'll see some broadcasts in 1080i, but never in 1080p because there is not enough bandwidth allocated to any HDTV channel to support a 1080p broadcast. Perhaps once we get past the digital drop-dead date (yeah right), we'll have some satellite providers helping out with beautiful 1080p feeds.

    Plasma displays are completely different from LCD's. They change color quickly, even quicker than CRT's, so in this respect they might even be better.

    Heh, funny you would say that.

    I just made exactly this decision. I had the money saved and wanted a high end viewing solution to go with my high end audio solution.

    What I think it boils down to is how it's going to be used.

    When you start comparing resolutions vs $ etc. Size is a matter of perspective - how close are you to the screen. How close /can/ you be to the screen?

    If it's going to be more than just you viewing the screen, then a large screen makes sense. But my primary usage was personal. I wanted something to play games and watch movies on. Other than what would end up being perhaps 1 movie night a month with a group for friends, 99% of the time it would be just me viewing.

    Huge dollars for $ 1024x760 on a big screen, or less $ for 1600x1200 on a smaller one?

    The other major consideration in a major purchase like this is HDCP. High Definition Copy Protection. If your prospective set doesn't have it, don't buy it, cuz there is a good chance you might not be able to view future HD content. (thanks MPAA)

    I chose to spend my money on a 21" Viewsonic LCD and an Nvidia Ti4600 to drive it, leaving enough left over to upgrade that purchase much sooner than I could of with the big screen.

    Because light guns rely on the horizontal and vertical blanking that's inherently a CRT thing. :-)

    Plasma and LCDs don't refresh that way, ispo facto: your light gun won't work.

  7. Gateway Plasma is NOT HD by tswinzig · · Score: 4, Informative

    I was amazed when I heard Gateway was coming out with a $3000 plasma HDTV. Then I found out why it's so cheap... it's not HDTV. You'll notice no where on their site do they refer to it as an HDTV or capable of DISPLAYING at that high resolution. You'll see stuff like, "capable of accepting 1080I and 720p HDTV signals," or "16:9 Wide Aspect Ratio," or "compatible signals include computer display resolutions up to 1280 X 1024 and HDTV signals including 720p and 1080i."

    However, notice the native resolution of the TV is only DVD quality (approximately 480 horizontal lines). That's twice as good as regular TV, but for $3000 I'll either fork out more for a real plasma HDTV, or a little less for a good rear-projection HDTV.

    I wonder how many people out there will buy one of these Gateway TV's assuming they are HD, just because they're plasma, 16:9 screens?

      Er, its a HDTV monitor. It does NOT have a built in reciever (hence the part that its capable of accepting those signals from an external source)

      Er, no it's not. An HDTV monitor can not only accept HD signals, but also DISPLAY them. A true HDTV monitor (i.e. capable of displaying at least 1080i) must have a native resolution of at least -- you guessed it -- 1080 pixels.

      Notice on this rear projection HDTV (which I bought a year ago for $2400) has 1600 lines of resolution... well over the 1080 needed to view a native 1080i broadcast. (The more lines the better.)

      The native resolution on the gateway plasma is 480 scan lines of resolution. It's not HD.

  8. Re:Burn-in by pbox · · Score: 3, Informative

    Most high end plasmas move their virtual screen around on their physical screen. This is a really slow process (ie. 1-2 minutes cycle time) and it only moves a few pixels up and down, so it is unnoticable. This is because they also realized that burn-in is an issue and they need to do something. I have personally watched a Sony 50+ inch at Good Guys for several minutes but it was unnoticable, unless I put my fingertip at the edge of the picture.

    However, it might not protect against burn-in in case of more static screens, like video games or public ad displays.

    To read about how the work (exactly), look here. As for the point, light guns shouldn't work (at least traditional ones). He's right that they depend on timing information. Interesting to see how House of the Dead III on the XBox gets around this, since the XBox can put out progressive scan. Anyway, it's the same reason (I think) that Timex Datalink watches only work with CRTs.

    Of course, light guns are based on technology almost as old as arcade games are (70's at least) so maybe someone will come around and develop a new one soon that will work with LCDs. I think we can all agree that LCDs are going to become common: they use less electricity, less space, and are 'cooler' ;)

    I watched a review of House of the Dead 2 on CNN HLN and they had it running on the plasma screen so you could see the graphics and then flipped over to a smaller CRT to show the light gun. They specifically mentioned that the light guns don't work on plasma screens, because of the lack of the blanking period.
