    Projectors aren't my thing, but I do come across a lot more LCD projectors than CRT, what are the pro and cons of CRT vs LCD? I'm not really looking to buy one, I would just like to know to satisfy my know knowledge. Thank you in advance to anyone who can help with this.

    LCD – Pros: small, convenient, easy to use, lower entry level cost, video quality improving with new generation Home Theatre friendly designs from Sanyo, Sony, Toshiba.

    Cons: Picture quality still lower than CRT because of poorer contrast, colour rendition lacks the subtle shading of CRT, have problems with dust pollution which means they need cleaning, pixels are known to fail and lamp replacement costs can be an issue.

    When choosing an LCD projector try to remember that most of the products advertised in magazines are designed for PC presentation rather than video. Simply buying the cheapest brightest highest resolution LCD projector won’t guarantee good performance with movies and TV. Do a search on LCD in this forum and you’ll find people discussing contrast ratio, colour accuracy, progressive scan etc. You’ll also see the same manufacturers products mentioned time and again.

    CRT – Pros: Superior video performance, the highest contrast ratio, excellent black level for good shadow detail, capable of producing a wonderful 3D image, quieter than the majority of LCD projectors, many have the flexibility to work well with either 4:3 or 16:9 screen shapes. Low running costs. Upgradeable. Tweaky type product – you can have as much fun setting these things up as watching movies.

    Cons: Higher entry-level price than LCD, physically larger, generally requires a specialist to install them and set-up the convergence, will require convergence tweaking once or twice a year. Few non-specialist dealers understand the technology so I'm affraid you'll find a lot of mis-information from dealers who sell just single lens product.

    CRT is a well-established technology that has been refined over a number of years. The choice of projectors isn’t as large as with LCD but you will find many CRT projectors are clearly dedicated for the home theatre enthusiast.

    Choose a projector that allows at least line doubling – Seleco 420/500/800, Barco Cine 6/7/8, Ellie, Sony D50 (if still available) and go and audition them. There is a big difference in price between some of the models listed here, a good dealer should be able to explain quite clearly why these differences occur.

    Choosing the right dealer for CRT is just as important as choosing the right projector. You need someone who knows the product well and can get the best from it.

    Good luck in your search.
