Good deal bro! Do share your thoughts when you've had some time with it.

Hey guys RS20 is looking great. I have it on THX setting right now.. I was going through the settings and under "HDMI" its on AUTO, I changed it to STANDARD and the black levels increased noticeably! I changed it to ENHANCED and they decreased. The setting AUTO & ENHANCED the black levels looks the same but STANDARD really gives the deeps blacks. I tested this out during credits.

What is the recommended setting for HDMI? Auto,Standard or Enhanced?

Just make sure you're not mistaking black crush for better black level. You should not loose shadow detail. If your source is outputting enhanced, what you describe seeing when setting the RS20 to standard may be black crush. If there are features visible when viewing in enhanced that disappear into the blackness when viewing in standard I think the video level is not matching.

I hope that makes some semblance of sense. It's late an I'm tired.

EDIT: The recommended settings depend on what your source is set to. Just make sure they match. Some go after whiter than white and blacker than black but I recommend just getting the levels agreeing first and then you can learn about WTW and BTB later and figure out whether the advantages out weight the disadvantages.

I think I understand. My source is a media player. I stream all my blu-rays from a server to the PopCorn Hour A-110. I'm not sure if popcorn hour has a setting to switch between standard/enhanced to match the rs20..

I find that the auto setting doesn't always work correctly. You do need to adjust the brightness and contrast controls based on whichever you use...if not the levels will be off (and note they will be different for each mode).

Is this something I can adjust or it should wait for calibration.
post #4837 of 5082
If you have a test disc, you can set the brightness and contrast yourself (the full calibration will do more complex things like grayscale, gamma, CMS, etc...).

Agree with the above. If you use 'Standard' HDMI, the Br and Cst settings both come out ~ 0 for most people; if you use 'Enhanced', they are typically Br ~ -5 and Cst ~ + 6 or a bit more.

+1, except I'll toss in that +6 on Cst is good if you don't want to clip WTW. For those looking to maximize brightness and CR the Cst can be set closer to 12 or 13.

My RS20 is finally getting shipped back to me today. It took a week to get there and then there was a 2 day wait for parts and then the next day it was being repaired and today it gets shipped back to me.
I had the problem with no lights at all and the lens clicking, like it was trying to turn itself on as long as it was plugged in. I couldn't locate on their website as to what they actually repaired. I hope it's on some paperwork when I get it back.
At least it was under warranty, but the shipping from MI to CA was $119.00 including the $55.00 for insurance. I won't have to pay for the return trip.

So say I put HDMI as Standard.. Is there a recommended setting to put the BR & CR at? Or is it different from each projector?

It's in principle different for each, but I think most people find Br = Cst =/~ 0 to be correct. (I know I do if I'm in 'Standard'.)
post #4844 of 5082
So I was playing around with the hdmi settings and had 2012 playing. Enhanced and Auto look like the brightness is to high. I am using THX mode here. If I lower the brightness to -1,-2 the image doesn't look washed out. -5 the image looks a little to dark. Would you guys suggest lowering the brightness to -2?

I have a DVE disc but I am clueless when it comes to calibration. Don't really know how to use the dve disc. Something I know I need to learn one of these days.

Also I have aperture set to -9

Break out a THX DVD or BD and use it for brightness and contrast setting. Invest in an EyeOne LT somewhere down the line, or just have it professionally calibrated.

Yes you do. I was exactly where you are just a few years ago, when I decided to make the plunge into front projection. It has been a great deal of fun, and the more you learn the more fun it is. I started with AVIA and then DVE and went from there.

I encourage you to make the effect if you have the time, for it is a very rewarding hobby.

I actually find from doing the RS series pretty extensively that most are -1 for brightness and -1 to -2 for contrast. However, as we know everyone is different and the source can definitely play a part in that.

Both values are slightly reduced?

Chrisx510:

I know I posted this on your theater design page as well. I also know that someones elses settings are no substitute for a proper calibration, but I tossed in the Rec 709 settings by Manni01 on the calibration thread: http://www.avsforum.com/avs-vb/showt...0#post16662220 with good luck on mine with the new bulb. I did tweak his brightness setting from -6 up four clicks to -2 as he is running his in high lamp mode and I am in normal. For the record my projector HDMI setting is in Auto, and my blu-ray player is in auto as well. Again no substitute for proper calibration but for me it definitely added some noticeable pop over the THX preset.

Yuppers. That is too avoid crushing the blacks and clipping the whites. Again though, a lot is source dependent (that is using a test pattern generator).

Did you mean to say +1 (instead of -1) for brightness? As you mentioned certainly there can be variations in the setups, but in my case I can say for certain that -1 on brightness would definitely crush blacks.

In fact the technically correct level for brightness in my setup is +1, but I leave it at 0 because I'll take the slight black crush in exchange for the inky blacks.

right now I have my HDMI to Enhanced on THX mode with brightness at -2. +1 makes the image look a little washed out.

Every setup is different...I am saying that taking a large sampling (not just 1 projector) overall they are -1. In addition, if you are measuring from your BluRay/DVD it is entirely possibly your player is skewing the settings. I use a test pattern generator and then fine tune the player to the projector at that point.

You need to AT LEAST throw in a test disk and set brightness / contrast to the appropriate test pattern. Just punching numbers in that someone suggests gets you nowhere.

Actually it does get you somewhere, it's just that you don't know where you are.
post #4856 of 5082
Yeah, there is pretty wide variation, when one takes into account the gamma settings as well. IE, you might be tempted to turn down brightness when really what you need in order to retain black levels and not have haze in darker scenes is some adjustment of gamma.

Do yourself a favor and get the Spears & Munsil BR disc. It is a great disc for beginners with explanations for each setting. Very easy to use and well worth the money to get the basics right.

Thanks I will look into that one.
