| 247172 | 2004-06-23 22:52:00 | Do LCD screens have a longer life than CRT screens? I will be upgrading to a new system and cannot decide if LCD is the way to go. They are of course more expensive but I seem to recall reading that the only long-term replacement needed is a small bulb that will eventually burn out - if true, this is a big advantage over a CRT since if it burns out then it is virtually non repairable. A 17 inch LCD is appealing, but in Wellington yesterday (at ATech Computers) they had a 19 inch CRT with incredible resolution. I want a screen for video and photo editing and possibly for viewing DVD movies (but not for gaming). I have heard that CRTs still have a better refresh rate and resolution compared to LCDs. Would I be disappointed with a LCD ? If LCDs last longer would they be a better buy in the long run e.g over 5 or 10 years? Thanks -- Steve L |

| 247175 | 2004-06-24 12:06:00 | Thanks guys. Godfather says "Life is limited by the backlight. New screens seem to be rated at 60,000 hours. 6 years +" .... but I still wonder if the "backlight" he mentions can be replaced. It is still not clear to me. After 60,000 hours (that is a LOT of time!!) can the backlight be replaced? If so, then this is a BIG advantage over CRTs when they burn out and have to be junked. By the way, I went into our local newspaper this afternoon (had a fantastic photo with a story that they will print tomorrow) and lo and behold the reporter-journalist-editor-or whatever they are called had a 17in Ultrasharp LCD screen - as seen in current Dell systems; she raved about how good it was and she was processing photos as I stood there. Reading Godfather's account (as per the link given above), another thing is not clear: can LCD screens be damaged, i.e. scratched - or do some of them have glass over them to protect the screens? |

| 247176 | 2004-06-24 12:10:00 | But, much better things may be coming along by 2010... Holographic screens anyone? |

| 247177 | 2004-06-24 12:10:00 | Perhaps this person raving about the screen should have mentioned they don't display colours correctly. And once you've seen a near brand new screen with a couple stuck pixels that aren't covered by warrenty you won't be at all worried about the backlight. |

| 247178 | 2004-06-24 12:11:00 | ..... just to clarify..... Godfather states that there IS glass..... but maybe it was a typo error on his part. I don't think there is glass over LCD screens but maybe on some newer models?? To shell out extra $$ for a 17in LCD, and then to have my wife or some visiting kid scratch it with a ring, finger nail or pencil - egad!!! |

| 247179 | 2004-06-24 12:15:00 | "with a couple stuck pixels that aren't covered by warrenty" Egad again! I recall a friend who dropped his laptop (he is old and has the shakes and is an absent minded type) and wound up with only half a viewable screen. I guess LCD screens are easier to drop since they are so light and easily movable compared to heavy CRTs that are moved slowly with care. Was set to go with an LCD but now I dunno. :( |

| 247180 | 2004-06-24 12:16:00 | a comparison. compreviews.about.com putting lcd vs crt into google pulls up a boatload of articles. and putting crt vs lcd into google pulls up another entirely different boatload. |

| 247181 | 2004-06-24 12:19:00 | You don't need to drop them to get a dead pixel,its a weakness in the tech and can happen at anytime to any lcd,irrilvent of which brand or how much you pay. I would stress paying the extra and purchasing a screen with a 3 year stuck pixel warrenty,and make sure its in writing. |
