The contrast ratio on DLPs is so great that it can cause eye strain in some folks when watching in a dark environment. The standard fix for this is to put a small light fixture behind the set reflecting off the wall. This helps keep viewers' eyes dilated. I've not had a problem with this either.

I've seen that the very brightest whites on our DLP -- for example,
when a show fills nearly the whole screen with white -- hurt my eyes a
bit when the room is completely dark. I've been considering putting a
small lamp behind the set, and I have a question:

I saw a website where some guy was selling a special lamp that's
supposed to be the very best for this purpose. I can't remember if
it's because it was exactly the right brightness, or because it was
wide and filled the area behind the set evenly in some way, or maybe
it was supposed to have a more natural light that was more pleasing to
the human eye.

Is there anything to this? I can't find the site's URL right now, but
I definitely recall that it cost a lot more than getting that old
upright lamp we've got in the garage, sticking a 15-watt bulb into it
and being done with it. Something like the difference between $50 and
free.


By the way, this is a pretty rare event, my feeling that the picture
is too bright. I think I've noticed it most on the bright default
menu of our Philips DVD player. Usually, all we do when we want to
turn off all the lights in the room is change the TV from "Standard"
to "Movie" mode, which we've set a little darker than Standard mode.

But I'm still curious about the special lamp from some website I can't
remember. Has anyone tried it? Is it any more pleasing to the eye
than any old lamp with a dim bulb?


I don't watch my set in a completely dark room (that would freak my parrot out), so I haven't had that problem and have done very little research on it. There were several large threads on avsforum.com discussing the issue with suggestions for "backlighting".

I'd assume the more expensive "specialty" fixtures have more appropriate mounting options and and the bulbs have some specific white balance, but that's just a guess.
