Plasma or LCD? 356

WeeBit asks: "I saw a news article on why you should buy Plasma instead of LCD TV's. It just sparked my interest. Flat panel TV's have the market now, and our analog TV's are on their way out. I am sure many will be thinking of purchasing their new flat panel within the next couple years. Have you given this any thought? Panasonic, has been pushing ads that sell the consumer on the plasma TV's over the LCD's. Is this a good argument, or is it just hype? Which do you prefer Plasma or LCD? Why?"

Plasma or LCD?

    Panasonic are the best manufacturer of Plasma displays, bar just about none. Even those painfully expensive Bang & Olufsen plasmas are Panasonic panels with upgraded processing components and a nice box.

    Meanwhile, their current range of LCDs aren't that great, and are generally considered to be, if anything, worse than their previous generation (they're cheaper to make, though). They're losing market share hand over fist to Sony right now.

    Exactly how unbiased do you think a press release from them extolling the virtues of Plasma are going to be? Roughly as much as the one explaining why you should buy one of their Blu-Ray players, instead of Toshiba's HD-DVD, really.

    Personally, I think both technologies have their place. Plasma really comes into its own at 50" and larger sizes, where LCD's finer dot-pitch is less of an issue, and you can't even get a decent-value plasma below 42" - the rare 37" ones are ludicrously overpriced in comparison to LCD. But Panasonic are definitely over-selling Plasma in their marketing.

    That's generally a good write-up, though I'd quibble with their first bit. Plasma being manufactured at generally larger sizes than LCD isn't really a 'win' for Plasma.

    Most people choose where they want a TV to go, and buy one that is the right size for the space, or smaller if they can't afford one that big. If you've got a 50" space to fill, then sure, Plasma is the winner. If it's 32" or lower, Plasma can't fit your needs. Overall, I think it's a fairly neutral thing - 40" seems to be the hotspot, and both are fine there.

    The problem (at least here in the UK, I don't know the US that well) is that ever since LCD went huge there isn't such a thing as "high-end CRT" any more. Anything over about 24" is going to show geometry problems to some extent (dear GOD am I glad I don't have to worry about geometry or convergence now I've gone to LCD), and when you get to 32" 16/9 sets its a pretty serious issue.

    Then there's the fact that the two of us nearly did ourselves serious injury taking my 32" CRT up the stairs. The 32" LCD that replaced it weighed 17kg. Including the packaging, which never made it up with the CRT, because that wouldn't have negotiated the corner.

    For small sets, CRT is still unbeatable on value and image quality. But for the living room it's dead as a dead thing.

    What happened to the promise of a cheap laser TV? Is this still in the works?

    I had a plasma for 4 days.

    On day 3 I watched an inning of baseball. Turned off the TV. Went to the store.

    When I came back I could still see the score. (The red sox were winning). I was very angry.

    The next morning the score was still there.

    I returned the TV on day 4.

    Good plan!

    If the (currently vaporware) SED TV [wikipedia.org] ever gets out it will make plasma and LCD obsolete.

    I bought a Pioneer plasma screen back in 2003 and it took no less than four months before I started getting burn in. I began leaving on a bright grey screen generated by my computer on it (second monitor output, grey desktop w no icons) and it reduced the effect but never wholly eliminated it. After about a year of owning this television, I began experiencing red/blue snow where there was supposed to be black. I literally threw it out, and have been using LCD ever since without complaint. Also, some of the newest generation LCD screens display at 120 hz, and alternate an all black frame between frames, this greatly increases contrast and eliminates motion blur. I think it's Samsung that is making these, I saw a demo a few months back and was quite impressed.

    Oh wait, they did that too with red, green and blue LEDs, which is killer because there's no gold at the end of that rainbow effect
    The fundamental cause of 'rainbow effect' is not a wheel spinnig around, it's having only one primary on the screen at any given instant in time. The LED array if implemented properly will have the equivalent effect of very high RPM color wheels (which they already are doing). I haven't noticed rainbox effect, but if someone theoretically did notice with high rpm wheels, they might theoretically notice with LED array. I don't know how they time the LED array intervals and by extension what the equivalent RPM/size of a color wheel wold have to be to equal it, but at the end it's the same basic strategy.

    The LEDs definitely have shorter time to full brightness, I hear they enable the sets to do a richer color gamut, and of course are much more longer lasting and less sensitive to power cycles. With LEDs DLPs ought be *the* sets to have if you have longevity in mind. LCD panels theoretically could break down more easily under heat, and I know damn well how easily LCD panels get dead pixels (every flat panel I've had developed at least one screwed up pixel within two years). The heat doesn't apply to flat-panel sets so much, but the dead pixels do. Plasma I hear has been criticized for losing quality over years, as well as burn-in. There have been improvements, but still... You're left with LCoS type systems, CRT, and DLP. DLP and LCoS may benefit equally from LED light instead of lamp. CRT projection has been very solid over the years, but subject to burn in.

    Well, yeah, the glass used in CRTs contains quite a bit of lead.

    My CRT Sony WEGA weighs over 200 pounds and I think that most of the weight is in the face of the CRT. This set requires a special TV stand just to hold the weight and there is NOTHING to hold onto when moving it. The old Sony TVs were rectangular boxes that had carrying handles, the newer ones are odd shaped round cornered blobs with no handles; the only flat parts are the bottom of the cabinet and the face of the CRT.

    It pissed me off when the set was delivered. I had paid for in-house delivery and box removal, which the salesman said was supposed to mean that the TV would be unpacked and set in place. I live on the 2nd story of a condo with a significant number of stairs from the parking lot up to the common door of the condo. I would have been happy if the set had been carried up the stairs and left in my living room, still in the box. I took the day off of work to be home when it was delivered. The delivery truck driver arrived by himself, with no helper.

    The driver told me that the warehouse didn't know that the set weighted so much so they didn't send a helper and that either I had to help him carry it up the stairs or he would leave the set at the curb. I called the store that I bought it from and was told that the delivery was my responsibility and that they had just arranged it for me. I called the delivery company and was told that they didn't have anybody to send out to carry it in and that they would refund me the difference between curb side and inside delivery. I was also told that if the driver helped me carry to it upstairs that I wouldn't get the $15 refund. If I refused delivery, I would have to pay for the delivery attempt, pay for storage, and pay again for another delivery. I helped the driver carry it upstairs.

    I talked to a lawyer about it and was told that I was out of luck; the law was on the side of the cartage company and the retailer was totally out of the loop, they had simply acted as my agent to arrange delivery.

    Never, never, never base your purchase on this!

    It is very common practice to modify screen settings to sell the preferred (ie larger profit) display.

    If you have the time (and patience), you can sit there and tweak each individual display to see the 'best' picture each can achieve.

    I don't see why this was modded as funny, I completely agree.

    LCDs and Plasmas are both being heavily marketed like we simply HAVE to have one or the other, a bit like Republicans/Democrats or Labour/Conservative. Personally I see problems with both technologies and I WILL stick with my 20+ year old Decca CRT until it actually fails. Just two months ago I recycled my old 14" portable which had served me well for around 20 years, but I haven't bothered replacing it since I can live without TV in the bedroom. I only hope that when the main TV does finally pack in I'll still be able to get a CRT to replace it.

    DVDs can still be watched via computers, but our little ones get by just fine without any TV shows of any kind.

    Small Miss did watch “Bird Television” one morning for breakfast, by sliding the curtains wide & looking out into the front yard. That’s the one regression we’ve seen — & it was cute.

    As well as power, you save a lot of space; not just for the box itself, but for the watching area.

    I am very sensitive to the rainbow effect. The other day I was watching my friend's new big screen tv... it was a black and white film. The rainbow effect was getting to me and I asked "is this DLP rear projection?" and he said "no, it's plasma". That's when I realized that plasma has the same problem with rainbow as old-school crt did: namely, it uses phosphors and those phosphors have different decay rates. I would have thought this would be eliminated because plasma doesn't need to SCAN. But apparently this plasma screen did scan, or something equivalent, which meant that I saw rainbows. Can someone please explain this?

To program is to be.
