I'm not sure if that is true as I always thought video decoding was deterministic (ie. every codec produced the same output, assuming effects were not applied etc.).VA + pulldown detection is also what I use with my 4670, and that was also my understanding. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />I have *all* post processing like this turned off entirely, and colour and gamma correction curves at defaults (flat). In fact I think the only other thing I've changed is to enable adaptive anti-aliasing with the highest possible quality.This setting effectively overrides any settings that you apply if they would overwork the GPU and cause dropped frames. I'm pretty sure you're safe from that problem without needing to enable that setting with a 6950! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />For me the golden rule is "whatever looks good to me is good". That may sound a little selfish or stuck up, but honestly I trust my own eyes and since it is my setup I'm not particularly fussed by what other people say or recommend. The other rule I have is "keep it simple". The more messing around, the more chance for issues and quality loss. To be honest there are so many things that can be tweaked in a video "pipeline". From codecs to renderers to GPU driver to display settings. In my opinion if you have a good display and good quality source material then most of that simply doesn't need to be touched. My starting point is always defaults for everything and to apply the minimum changes required until:1. The colour - especially skin colour - looks realistic without over saturation or washing out.2. Black levels are as low as possible while maintaining good contrast.3. Deinterlacing quality is good with smooth motion for horizontal (tickers), vertical (credits) and "random" motion.4. No frames being dropped.I always start with my display colour, brightness and contrast settings first with settings recommended by a good review (tftcentral, prad.de etc.). You have to take them with a grain of salt as each panel will be different and you're not going to get it "perfect" without a colourmeter. At that point I'll use mostly static reference images for evaluation. Then I do the deinterlacing stuff in the GPU driver with high quality high motion video that I know well. Mostly that is all I have to worry about. The rest just falls into place...mm<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
