Read my 2 last posts on this page. The tv supports deep color but the problem is that not blu-ray discs nor dvds are currently made to use deep color. For what I have read deep color has nothing to do with Color Space aka limited (16-235) or full (0-255). The numbers mean blacker than black and whiter that white colors. For most tvs the correct color space is limited, and this option is to be set on the device you use for playng movies not the tv. Movies and videos are 8 bit color wich means 8 bits for blue, green and red each. Deep color means that you have 10 or 12 or 16 bits depending or the TV, in our case the hx850 is a 12 bit color. So if you active deep color you will have 12 bits for blue, red and green each. You cannot activate deep color on the tv perse but on the device you are using to see movies and videos, so you cannot use deep color with your cable box or dvr but instead just with your bluray player (if the player suppors it of course). I use a ps3 for my movies and you have the option under the display settings to activate it or not.
Now, the real problem is that for the deep color to work properly 3 things must work together: 1. Have a tv that supports deep color (check) 2. Have a player that can output deep color (check with ps3) 3. The most important thing to have a blu-ray or dvd disc that is recorder with deep color information from the start (a here lies the problem). There are not any movies that have deep color encoded, maybe with next generation consoles and nex generation Tvs(4K) they will begin producing deep color movies.
So if you activate the deep color feature with your ps3 or any bluray player that supports it, you'll be seeing different colors indeed (they will be more saturated and color banding non existant) but the adittional colors are not encoded in the discs but created / estimated by player, hence the colors are wrong!. Iniatilly you will think when you see the picture that is beatiful but on close inspection you'll notice how bad the colors are represented and in fact a less detail picture. For example blood will not be deep red but with a litlle pinkish tone.ATTENTION FOR PS3 USERS, BEWARE OF THIS PROBLEM
: The deep color option under display settings is set to automatic by default. In our case with the hx850 the ps3 reads that the tv can output 12 bit color, so it activates the deep color funtion automatically without you knowing. The problem is that with this option enable the PQ will be lessen by the innacurate colors!. Until blurays or games comes with deep color encoded THIS OPTION MUST BE SET TO OFF. You will know if the signal from the ps3 is in deep color by hitting the display button to verify if its says 1080p/720p 12 bit. Deep color is a feature dependant of your tv, some tvs with deep color on automatic will continue to output the same image but with hx850 is not the case. I have compare video games and movies with the option on and off and you can see difference indeed. Do yourself a favor a set the option to OFF. Also turn the super white funtion On only to calibrate your tv then you must turn it Off again, because if not it will also lessen the PQ.Edited by fegam2 - 7/22/13 at 12:27pm
