I think I have an answer about the black crush that I've been seeing.
This player chooses on what it outputs regarding 0-255 or 16-235 in YCbCr mode. Yes it outputs 0-255 in YCbCr.
I have been able to repeat the problem. I do not know how this works with HDR, or if it is a problem with HDR, but it seems to be plaguing my 1.4 [email protected]
8bit SDR JVC projector.
I first noticed the problem when watching Netflix on the player and blacks were smashed. I also noticed that the menu had crushed blacks. I double checked the color format, it was set to YCbCr, my JVC was set to Standard.
I switched the player to RGB (Standard) and the black crush was resolved while the absolute blacks were still black. I then switched it back to YCbCr and the picture remained the same. I thought that was odd.
I started an UHD disc, the loading menu was... loading... and then when I was prompted to resume (yes or no) my screen flicked black for a second and the black crush came rushing back in. It seems the disc demands 0-255 over YCbCr.
I went back to the player's settings and tried the cycle again, and the same thing repeated. Then I decided to run the settings on the player at RGB (Standard) while playing a disc. The black crush was gone and a "proper" 16-235 mode was present.
So at this point I have two choices for a proper gamma.
1. Run the player's settings at RGB (limited) with the projector in Standard input.
2. Run the player's setting at YCbCr with the projector in "Enhanced" input.
One member here said that 0-255 was not a thing over YCbCr and my projector must be interpolating, but clearly 0-255 is being sent over YCbCr. So why is this happening, and why don't I see anyone else talking about this?
