Ok, just watched my first Blu Ray on my new PJ. (Viewsonic PRO8200). Its mounted in a room measuring 10ft wide x 12ft deep. Mounted at approx. 11ft from the wall on which it is projected on (just showed up two days ago so haven't built a screen yet) and is stock settings.

We were watching "The Dark Knight Rises" tonight and the scenes that were lighter were incredible. However, the scenes where its really dark ie caves (which this film has a lot of: like 70% ) it was so dark that you couldn't make out any details other than a faint glow on the faces of the characters.

So I know that I need to calibrate my PJ, and I know I need to get a screen mounted. (I've ordered the Disney Calibration Blu Ray and plan on building a projector using black out cloth this weekend) But when I do these, what specifically do I need to pay attention to, to make sure when I watch this again, I can actually see some stuff during all those super dark scenes??? Also should I be using something other than Black Out Cloth to make it brighter??

I plan on watching the movie again tomorrow on my Plasma to get a comparison as my buddy who was over and had seen the film said it was super dark on his TV, but I feel like this PJ could do better in those dark scenes. I cranked up the brightness, and it helped, but didn't really change the hues I guess.

Anyways, I'm a complete noob to this and would appreciate any information you all could offer. Thanks in advance!

Try Brightness 53 contrast 47 (I think, forgot). Although depends on how dark you have your room.
Somewhere around there should get rid of most of the crush unless your bluray player is adding it, also turn off HDMI enhanced or deep color in your Bluray player as it may cause the VS to crush blacks.

Ok, I'll give that a try. I went in before the movie yesterday and turned off Deep Color on my PS3. But I turned on the 24hrz would that have anything to do with it? Also my room was completely dark, one window has blinds and drapes on it but it was also night time, the door was closed, so the only light was coming from the PJ.

It was almost as tho the darks this PJ produces is too good haha. I'm very impressed, just know I need to tweak it. I think building a screen will help a lot too.

Thanks for the reply.

Thank you! Fantastic information. Really appreciate you taking the time to cover all those settings. I'm working on building the screen today and will make these adjustments. I'll report back with what I find.

Most likely it's an issue with gamma.

Read this, very educational:
http://www.curtpalme.com/forum/viewtopic.php?t=10457 and also this
http://www.curtpalme.com/forum/viewtopic.php?t=6861

I think those posts are a bit outdated but the info is still good. If I'm not mistaken ColorHCFR was abandoned by it's original creator and then picked up by other folks so there have been changes. Judging by other folks here it seems that calman and chromapure software is better than ColorHCFR but HCFR is free.

You probably need to calibrate the greyscale and if you still find it unacceptable then you'll either have to

lose details in the dark areas or
turn up brightness and lose some black level (could possible lose white detail) or
buy a device that has gamma boost

Those "calibration" discs are okay for what they are. But just realize it's just an eyeball calibration, it will help adjust basic controls but to get the blacks to stay dark where they are supposed to and also get decent dark detail while maintaining proper luminance in mid and higher IREs you really need to be able to measure and correct greyscale. The guide I posted to above is a good intro into calibration. Actually on second thought, there is no reason to ever buy a calibration disc, not when some fine folks here at AVS put together a disc for FREE.

http://www.avsforum.com/t/948496/avs-hd-709-blu-ray-mp4-calibration

Also make sure you have controls that will let to adjust greyscale before shelling out money for a meter and software. No reason to see all the errors in a display if you can't correct it, it will just end up irking you.
