Here are also some general "rule-of-thumb" recommendations we recommend:

Bright Room: 50-60 fL
Dim Room: 40-50 fL
Theater Room: 30-40 fL
Theater Room Projector: 14-30 fL

This of course, measured at 100 IRE luminance level.

I have the following question about fL for LCD TV in a bright room:

I calibrated my Panny projector AE4000 for a light-controlled environment with 14 FL @ 100IRE. Everything is fine, including the overall picture brightness. Then I went ahead to calibrate my Samsung LCD TV. Since I always do my TV viewing with a lot of in-room lighting, I thought 50 fL is probably the target for me to go. However, the before-calibration measurement revealed that ~12 fL @ 100IRE and gamma of 2.11. The fL seems incredibly low but I'm comfortable with that level of brightness (at a viewing distance of 9 ft). So I ignored that "recommendation" of 50 fL and calibrated the set with the resulting gamma of ~2.0 (since the viewing environment is bright) and ~11 fL @ 100IRE. I am comfortable with the overall picture brightness. How to explain the fact that my result is so different from the "recommended fL"?

The calibration environment was totally dark; and the colorimeter (Spyder3)was sit tight on the LCD screen.

If you are calibrating in a totally dark environment, 50fL is going to be like a flashlight! I personally can't even stand 30fL.. only maybe during daytime.
In a totally darken room, 12-14 is what I feel like really good enough. 11 might be a bit low, but it is all about your own taste. A bit higher may give you the extra "pop".
The next thing to do is watch yours in a bright setting. I am pretty sure 11fL is not going to be enough for you if you turn on a few light.

I do watch it in a bright setting (i.e. with in-room lighting) with 11 fL. Not sure if it is the issue related to my measurement, or in fact my eyes are not adapted to such "bright" (> 11 fL) pictures in a LCD TV.

For projector, I'm perfectly fine with 14 fL in a dark environment.

11 fL is pretty close to the range. You mainly want to avoid getting down into the mid single digits, as that starts to infringe on perceived picture quality. Personal preference is a phrase I generally like to avoid when discussing calibration settings, but I think you can certainly make a valid case to be on the lower side of the range, especially if you are the type with more sensitive eyes or one that watches for extended periods of time.

Yes it's quite low. It's unlikely it's correct since at that level a typical direct view display would be completely washed out by almost any light that impinged on the front.

I'm assuming that when you say bright you don't mean simply relative to your projector settings but you mean typical evening lighting in your living room.

Yes, I meant the evening lighting in the living room.

Thanks both bodosom & Louerhardt for your response.

I glanced at the manual and didn't see much there that would possibly affect overscan. The only thing I can think of would be to ask in the owners thread where people would be more familiar with the TV.

First of all, thanks for putting this together.

As far as my Philips BDP3020/F7 with latest firmware, it doesn't work with either the Patched or AVCHD burned discs.

But does work with the HDMV disc.

I ended up using the MP4 files on my PC connected to my 32EX400 through VGA input.

The HDMV version will fit on a DVD. Some (most?) BR players will accept BR video on DVD.

One of the Magnavox players was reported to not play the AVCHD or Patched, but it would play HDMV on DVD. The online specifications for the Philips do not list AVCHD, and it does list BD-R/RE, so it's possible it may play HDMV on DVD. The "Write files/folders" option in ImgBurn can be used to do this. The program should identify the need to switch the disc formatting from the defaults and ask the user if the change should be made, or else the UDF formatting can be set on the options tab for "Filesystem = UDF" and "UDF Revision = 2.5".

Hello guys,

I'm new to this, I bought my first plasma today, it is a Panasonic TH-P42A20M and I'm looking to adjust the settings the best I can. I downloaded the DVD, however, I don't really know where to start. Will running the "Basic Settings" menu be enough? I don't have any calibration software or programs you are talking about, all I have is my plasma, this DVD, and a PS3 to run the DVD. Any suggestions or recommendations?

Thank you very much.

DVDs are useful in getting Brightness, Contrast, Color and Tint fairly close on your display. If you are unfamiliar with how to use the patterns, this forum and many YouTube videos have some great descriptions of this.

Remember that Brightness is your Black Level and affects shadow details - the difference between a video black and the next step up. Contrast is your white level - here you ensure there is a visible difference between the brightest white and the next step down on the greyscale.

I recommend seeing how some patterns are used, and again YouTube has some great videos to reference in this regard.

Good Luck and enjoy the new TV!

Have you looked at one of the Patterns documents attached to the first post in this thread? It has instructions.

I just do the basic settings by eye myself. To do color you'll need a blue filter unless your display has a blue-only calibration mode. I use the THX glasses: http://www.costore.com/THX/producten...=87&pid=930793

Thanks for doing AVS HD 709! I've found it to be very thorough.
I'd like to get some of this, especially the APL patterns, to play on a WD TV Live via a USB Cruzer stick.
I downloaded the MP4 files and put them on. They play, but the WD doesn't skip back and forth in the chapters; for example, I can't skip from the 0% to 10% patterns.
Is there anything I can do to fix this? If I get a bigger USB stick, I could put one of the different format .iso files on it, but I'm a bit of a newbie when it comes to media servers and burning disc images, so I don't know if that would fix the problem.

Unlikely the WD TV can read .iso file...
You try fast-forward? It might take a while, but usually each pattern last for like 3-4 mins, and it should advance on its own. If you can skip chapters, maybe you can fast-forward it... I personally have not try, so that's all just my $0.02.

While using Misc patterns A4 - Flashing primary colors, I find the red boxes to be flashing when viewing through a red filter(My TV has inbuilt Red,Green,Blue filter). Green and Blue boxes show little to no flashing when viewed through respective filters. I am a bit hesitant to adjust the color since green and blue seems ok.. Should I adjust the Red color/Red tint/Red contrast/Red Brightness? Please advice..

Yes, it does fast forward. I guess that can do in a pinch. Thanks!

I've found fast forwarding is pretty clumsy and time consuming, though it does work.
What about downloading the images themselves? The WD TV live can display images or video. Spectracal uses it displaying photos as a pattern generator. That's actually what I have, but I think it would be very helpful to have APL patterns and some others, so I'm trying to add to it.
I've looked through the thread for a while and can't find any info if that is possible.

MP4 doesn't directly support chapters. There are some work around options, but none seemed to be widespread enough to consider including. The current MP4 version was just created to fulfill requests for a more computer-centered version with as little time invested as possible. Having individual video clips would probably make more sense for the MP4 version, but it's not how the main Blu-ray based project was developed. Having individual clips would appear to work for the WD TV Live, since the manual lists skipping between video clips. On a quick search the only other possibly viable option I ran across would be using mkv chapters from a pulldown menu on the WD TV Live.

Attached are the files that we use to create the Basic Settings (decompress .zip and .7z). The "1-BasicMod.avs" can be used to create the first chapter from the Basic Settings if you place the .yuv files in C: on your computer and follow the instructions from step 3 in http://www.avsforum.com/avs-vb/showt...4#post16837914 to create the video. The rest of the project could be produced this same way, but the files here are just an example of what would be required for anyone that might be interested in having individual MP4 clips.

Red color and red tint would probably correspond with the test if you have that much control. Current mainstream TVs usually don't have that option to split colors and they just come with one color and tint control, so I cannot really anticipate any items that might arise from adjustment. The two TVs that I've spent much time with that had these sort of options had different items to consider when making changes. Basically where I'm going here is that I would personally be more comfortable making these sorts of changes if there was a meter to check any other changes that might happen, or else I'd have to fall back on just watching video material to check what subjective changes happened with adjustment.
