No.
Use this image: http://www.mediafire.com/convkey/e4a...b9ur3m97zg.jpg You will clearly see that the downscaled in Linear Light keeps the visible brightness as the original image. Look at the small detail squares (AVS HD709 written) ,white text and fine detail. Now turn LL on and off in window mode, and go back and forth fullscreen and window with and without LL.

However, the image by James Freeman is totally synthetical, whilst the image from Wikipedia is actually naturalistic. Are there any real world images that show a real "advantage" with ll scaling? It can definitely look too bright. You can try this with games: Capture one screenshot in native resolution and the other e.g. with 4x higher resolution by DSR. |

your panasonic TV is with it's current settings not 4:4:4.
the result is a little bit strange usually the picture gets more dark not more bright but could be easily the result of an uncalibrated screen. supporting RGB as input doesn't mean it can be displayed same for bit deep. 12 bit input and RGB input is totally normal for all TVs but nearly all of them are not even 10 bit and a lot can't display 4:4:4 too. |

But don't try to set Catalyst to YCbCr 4:2:2, that way you will lose even more. |

One more question .. Should I choose 8bit instead 10bit in AMD CCC for Panasonic TV? I am not sure I can see any differences in picture quality

There were an opinions here that plazmas handle 10 bit their own way without any real benefits. Make sure you have set yours the right way. Personally I always set my TVs to PC mode for decent RGB 4:4:4 handling. That means a playback on 60Hz dispaly, but its ok for me, smooth enough. Check out your TV modes to find out the most suitable for madVR's technology and your visual perception. |

Personally, I would always do a quick test with a good grey ramp test pattern, and if you really don't see differences, then 8bit should be fine, but it's very hard to tell differences with actual movie or video content if you don't have the right samples, so a test pattern will solve that for you pretty quickly.

@madshi
Is it possible to have an option to use D39 overlay in windowed mode and D311 in exclusive mode? I like that overlay keeps the gamma ramp for the desktop and disables it in the player window for use with the 3DLUT. Yet, it seems that I have a 10-bit display and I'd like to take advantage of that which requires D3D11. |

http://madshi.net/madVR8810test3.zip Please let me know if either of them works (or both). If either of them does *not* work, please upload a debug log for that. If both don't work, please upload a debug log for both. Thanks. |
