Is it best to have 1080 pixel direct turned on or off in cinema mode when watching blu ray through OPPO BDP-83?

Cinema (not THX cinema), Custom and Professional modes are good because they will not dither down an 8-bit signal, you will lose some overall brightness but have better gradation. If you are watching Standard definition it won't make much of a difference but rendered or uncompressed content will look alot better and retain every bit of detail from the source.


1080 pixel direct is really only useful for PC RGB signals and will kind of unintentionally screw up everything else

If you’re using a PC with the TX-P42ST60B, you can get full 4:4:4 chroma by using the [1080p Pixel Direct] mode, which on its own will result in large edge halos. These can be defeated by setting the “HDMI Content Type” for that input to “Photo”, although this may have an impact on colour accuracy with some content (it appears to make no difference for RGB content from computers, but changes colour decoding with YCbCr video, like what is commonly output by set-top boxes and disc players).
