I got his response, I pointed him to this thread. His explanation makes sense but I still worry a little with the contrast that high. But he is the pro so he knows better than me.
Hopefully Chad takes a look at this and confirms everything to put my mind at ease here
Sorry for the asterisk, it seems to happen when I copy paste from gmail.
Thanks for the emails!
I'll addess several things:
1. Contrast in the 90's is fine as long as it doesn't cause large grayscale discolouration or clip the image, which it didn't when calibrated. 43fL is perfectly fine for moderate to dark lighting which is what I categorize your room as. 35fL recommended for dark rooms but for REFERENCE DARK ROOMS which means very darkceilings and walls. Many people seem to forget that point as the 35fL came about for video mastering in studio environments...our houses are not studios... When ceilings are white and walls are of average brightness...this light energy is being reflected back to the screen and then back to your eye...which makes the TV look dimmer and lacking contrast. Thus, 35fL tends to be too dim for most room environments, which is why fL in the low 40s is a good choice. You may find it a bit bright because of eye fatigue and the distance you are sitting from it..but that's contrast ratio for you! Putting a panel light behing the TV will alleviate this problem - part of the reason why it was designed. I'll find out the shipping cost for you.
2. AVS is full of information and misinformation.It is full of posts with users who are not trained in the field I am in and do not have the measurment tools that I use.
3. 43 is perfectly fine for Brightness on your TV. Be careful about real detail vs. perceived detail. Remember the black background pattern with the dark gray and black strip on the black background? The darkest black bar is information in the video signal that is there but was NEVER meant to be seen. Yes, you could raise the brightness control up and see some new information, but that information was never intended for the audience to see which is the reason why those test patterns exist. At 43, 3%-100% video information is being displayed. In order to get a gamma of 2.2 - recommended for your lighting conditions, the brightness control needed to come down below the point when black just disappeared into black. The 4% bar is still light gray at this setting which isn't right either. If we leave it set where the bar just disappears (54-57), that's not the hard-set rule that needs to be followed. Panasonic gamma will dial in at 1.87-2.06 at this setting of 54-57, which is unacceptable for dim room environments. 1.9-2.0 is for bright environments. Given that there is hardly any useable information in the video signal in the 1-2% range and it's the closest thing next to black, it's a more than acceptable trade off to get excellent gamma which is far more important. Does the screen look a bit darker in the blacks? ABSOLUTELTY! That is what you paid for - a Panasonic with excellent black level! If we want those blacks to be gray...well, then there is the LG.*
So, that's the reason why the 2% bar in DVE is gone. It's a judgement call - save 1-2%, or get excellent gamma giving you a three dimensional image. The latter is the better choice! The 4% bar should just barely be noticeable as it's hardly above black! If it is bright then it's not right!
Thanks for the thread link. Your X-Box is passing black at the same level as your other components. Yes, the bottom image is darker, but based on what I can see on this monitor, the details are still there but just much darker which is the decision of the creative content producers. It may be that you are not agreeing with the artists of the game in making a very dark room and find it frustrating to navigate. That may be what they are intending. Also, game production is a bit sporadic...I don't think those guys are up to speed with video creation and monitoring standards as they are in Hollywood. ...and the The Dark Knight...well, that is a dark film! Doug and Chad are good guys. Thanks for keeping it confidential although you are free to share the information I've written you here in your own summary. I will send you your files by week's end
