    Hello all<br />I may be able to get one of the following projectors cheap. Does any body have any of the following or any thoughts on the following.<br /> <br />PLC-XP18 highlight 2000 Lumens, Unique progressive scan system for high quality video images <br />PLC-SW15 850 Lumens <br />PLC-XU20 1000 Lumens<br />PLC-SU20 1200 Lumens

    All do 16:9 widescreen. All can zoom.<br />Questions:<br />What is Uniformity? This differs slightly on each of the projectors.<br />What is contrast ration again this differs on each.

    What difference does the size of the LCD panels make? They range from 0.7" to 1.3".

    Looking at the specs the XP18 sounds great although its going to be the hardest for me to get hold of. So thoughts on all 4 would be appreciated.

    Thanks<br />Luke

    If you want these for a powerpoint presentation then fine. Several are very suitable.

    If you want these for Home Cinema, then I would advise you to look elsewhere. Sanyo has spent a not inconsiderble amount of time and money in optimising the PLV30. They have done it for a reason.

    A good powerpoint projector does NOT make a good home cinema projector.

    Some of the Sanyo LCD projectors make excellent Home Theatre projectors. Certainly the XP18N and the XP21N would be much better than the PLV30 as long as a HCPC or a good scaler is used. The PLV60 would also be a good choice again as long as an extrernal scaler is used. If you just want to plug in a DVD player or Sky (directly) then the PLV30 is a better choice because being low res it doesn't have much scaling to do and has been designed for this purpose.

    Hello<br /> Thanks for the replies. The Projectors that I have listed are the only models I can get. They come into where I work most of the times they have not been used but we do not resell them. Normal cost it £700 so as you can see a very good cost saving. I currently have a PLC-SUO7N its very good but the models have have listed have a higher lumens rating and other differences.

    Thanks<br />Luke

    I have used all of the machines on your list extensively (including the SUO7)<br />so my choice from the list (excluding the XP18) would be the XU20,<br />a very underated machine,and in some ways better even than the XP18!.

    I would still like the following questions answered:

    What is Uniformity? This differs slightly on each of the projectors.<br />What is contrast ration again this differs on each.

    What difference does the size of the LCD panels make? They range from 0.7" to 1.3".

    Thanks<br />Luke

    Luke, OK, here goes...

    "What is Uniformity?" - it's a measure of how evenly the projector illuminates the screen. 100% would mean that the image is equally bright from the centre to the edges. No manufacturer has yet achieved this figure with off-the-shelf products.

    90% means the image looses 10% of its brightness at the edges. This is a respectable score.

    The lower the figure, the more pronounced the difference in brightness from screen centre to edge.

    Projection screens can also affect uniformity. A high quality screen will give more evenly illuminated image; a wall painted with white emulsion paint will produce a much poorer result.

    “Contrast ratio” is the difference between the image brightness from black to white. Higher contrast ratios are generally better as this means black areas in the image should look less washed out; this is desirable for home cinema.

    A LCD projector designed for business use might achieve 250:1; a home theatre LCD projector might produce 500:1. A typical home theatre CRT projector would achieve 1000:1. Don’t get too hung up on the difference between contrast ratios for LCD projectors; higher projector brightness (ANSI lumens) can skew the figures. I would rather live with a PLV30 (500:1 contrast, 500 ANSI) than a Sanyo XP18 (700:1, 2000 ANSI).

    “What difference does the size of the LCD panels make?” There are lots of technical differences, but in general, smaller panels are easier to illuminate so produce a brighter image from the same power lamp. They also allow manufacturers to make smaller projectors.

    Specifications are only a rough guide to performance. You should always look at the image and decide for yourself if you are happy with the performance.

    Regards
