NEC LT170 – Image Quality

Image Quality: Data (computer): Clarity and Color Handling

Clarity is excellent, with the lens having no problem providing a sharp image from edge to edge.  Everything is nice and crisp looking, without the far more visible pixels of an LCD projector.

I observed the NEC LT170 at native resolution (XGA 1024×768) and it was excellent.  I also fed the projector UXGA (1600×1200) and was impressed by the compression technology.  As expected, smaller type became thick, and less than beautiful, but it handled my test spreadsheet with various fonts, sizes of type, and colors, extremely well.  If you feed it that high a resolution on large type, like Powerpoint, any degradation is minimal and probably only detectable to the “front row.”

Color Handling

I better start by saying this is a DLP projector, and accurate color is a huge problem for most 1 chip DLP models (all DLP projectors under 30 pounds and $20K).   This is hard to say.  If accurate colors are important – you need bright reds, and bright yellows  and you don’t want those reds to be dark wine colored, or those bright yellows to appear a muted, mustardy greenish yellow, then the NEC LT170, out of the box, isn’t the projector for you.

That is because the LT170, in its normal Presentation mode, gives you muddy greenish yellows and dark wine colored “bright reds”.  The image to the left, should have a bright red background and a bright yellow pie slice in the front left, and should look like this:

Below you can see a shot of the projected image, with the screen of my Dell laptop, below, in the foreground.  The color difference is obvious.
