    I am in the process of purchasing my first home theatre projector and my choice is between LCD (NEC VT 540) or DLP (In Focus LP 350 or 530).<br />I have heard that LCD may lose pixels over time resulting in nasty fixed dots on the screen while DLP is relatively immune to this problem.<br />Is this true?<br />Any recommendations on what may be my best choice in this price range?

    A word of warning about DLP - some people are sensitive to the "rainbow effect" which makes DLP unwatchable for them. Some DLP projectors are better at masking it than others. e.g. on the sim2 HT200 and HT250 I notice annoying flashes every couple of seconds. With the HT200DM I only noticed it once during about 3 minutes. So, before you decide on DLP, take yourself, family and anyone else that's likely to be watching it along for a demonstration.

    After that note of doom and gloom <img src="wink.gif" border="0"> I have to say that the sim2 HT range have very good contrast and colours, and they have reduced the rainbow effect greatly with the 6 colour wheel on the DM model.

    As far as dead pixels go, I believe (and this is the point where someone like Chris Frost jumps in to correct me <img src="wink.gif" border="0"> ) that the number of dead pixels does not increase over the lifetime of the device.

    I'm not exactly sure what your price range is, but you probably want to look at the Sanyo PLV30 (excellent contrast for LCD) at around £2300 and the Sony WH10HT which is being discounted heavily as the 11 model is due out soon (now?).

    Cheers,<br />Liam

    DLP is certainly less prone to dead pixels than LCD.

    LCD projectors can lose pixels over time if they get very hot because of poor ventilation or blocked filters, or if they are handled roughly. However, this isn’t normally a problem in a typical Home Theatre unless the projector is moved frequently or boxed into a sound proof housing.
