HOW TO: correct output range (btb/wtw) displayed

THX-UltraII · 3rd March 2010, 12:12

Been following the 'BTB/WTW' topic on the avs forum for some time now. I still don t understand how to config my system properly.

Here s some information:

- I only play standard def. and HD1080p video content (dvd, blu-ray, m2ts, wmv, mkv, mpeg, mov)
- I own a JVC RS20 projector that has a 'HDMI range' option that can be set to 'Standard' or 'Enhanced' (set it to standard)
*video card:- My HTPC has a ATI 5670 card and I use the original HDMI output of the card. I have the latest cat. beta 10.3 installed and the Realtek HDMI 2.42 audio driver.
- I have set the ati CCC Pixel Format on 'RGB limited'**
*mpc-hc:- I use the latest MPC-HC with EVR custom as renderer
- In the renderer settings in MPC-HC the 'Output Range' is checked at 0-255 (default)
*ffdshow:- use ffdshow video for all my content
- configured ffdshow as RGB32HQ output
- checked the box 'select closest matching colorspace' in ffdshow (default)
- changed the input levels in ffdshow from 'Standard (Y: 16-235, CbCr: 16-240)' to 'Auto'
- Output levels is set to 'Computer monitor (RGB 0 - 255)' (default)

**I used to have it on 'RGB Full' and my projector on 'Enhanced' with my ATI 4xxx card, but the new 5xxx-serie seems to have a problem with the 'RGB full' Pixel Format (not sure about this, maybe someone can confirm?)

All in all there are a LOT of settings that can be changed and I really don t know how to configure everything correcly since there are so many different settings that might have influence on showing the correct blacks and whites.

Hoping for some tips and input.

Cheers and thanks!

Check out this post. You basically want the same results from his attachments.

You want to avoid double compression/expansion type of issues or your PQ will go to hell.

I set MPC output levels to 16-235 to match the video encoded levels. then if required, I tweak the video drivers to give me what I want. I use the test images/videos to help ensure I've got things right.
