So what's the consensus on white segment on/off ?? I have it turned off right now.


Are there any cases where the white segment turned on gives a better PQ?

Checking it on increase brightness but lessen contrast. So if you're watching with lights on, checking it on may help improve brightness. Watching it with it on in dark is too bright in my opinion. Image appears washed out a bit with less contrast.

The above thread on LT 150 blacks seems to point out that LT150 white segment infact would give a better CR if it is on??


Grant smyth also seems to favor this. Grant, can you educate me further on this??


Thanks

I prefer watching movies and other video sources with the white segment off. The only time I have it on is when I'm using the PJ with a Windows desktop in high ambient light conditions. For example, I hosted this year's fantasy football draft at my place (in the home theater) and the CBS Sportsline site looked nice and bright with the white segement on.

The other thing I have noticed is with white segment off, colors are more saturated and realistic.

Currently, I have my white segment turned on. For me having the segment on, but the brightness setting turned lower seems to increase the shadow detail.


This is not definitive, just what I've been playing around with lately.

Take a look at Thumper's postings concerning the LT150 with white segment on and off. With it on he has measured contrast ratio at 1000:1 and with it off at 600:1 - both extremely good for just about any pre 16:9 DLP. For the good transfers (and most recent transfers are very good) I am now leaving the white segment on and with the screen I am using I am getting a great image - don't forget I am using an ISCO II anamorphic lens and this might improve shadow detail just by itself! If a transfer exhibits "crawlies" and other video noise then I switch it to off.


Part of the fun of this hobby is experimenting - try different settings and see what you like - it's your HT so you're the boss. Let me know what you prefer and if you're trying other settings pass them on and I'll give them a try.


Cheers,


Grant

If you want to maintain even color temperature across the greyscale range, white segment must be off. Contrast ratio will suffer a bit, but your colors will be more natural and more accurate.
