Replied to your same post in the Yukimura firmware thread. It's gone for me too. I'm guessing/hoping this was an unintentional result of deploying the new patch and it will be fixed with a 2.5.1 or 2.51...if it was intentionally removed the reason should have been documented in the release notes.Do you guys still have this option in Video output settings after yesterday's patch? It's used to right below RGB option - above deep color option. Now it's gone and graphics don't look as good through my monitor. WTF.
Your $700 monitor is RGB, not YCbCr, as is the case with every TV and monitor sold. Also, whoever said that RGB is standard def color space has absolutely no clue what they are talking about. They are simply spreading false information. The PS4 games I've played since the patch have looked the same as it did before the patch.
Have you calibrated your monitor?
The real issue (and point that I forgot to make) here is that YCbCr looks exactly the same as RGB, IF you recalibrate your monitor after switching. There will be no difference between the two if you recalibrate.
So if you had everything set up and calibrated for RGB and switched over to YCbCr, your calibration is now off and your picture quality is "technically" degraded. I say technically because people often misconceive more color saturation, contrast boosting, etc. as better, when it is in fact degrading your picture quality.
If you're manually setting the eizo to limited RGB there's no conversion or processing happening. If you manually choose it on the PS4 either one or the other is going to be an exact match for auto, most likely limited. I dont even think the PS4 will ever output YCbCr in games or anything but video, so I dunno why you're perceiving any difference in games regardless of what you choose for that.The Eizo monitor handles the conversion alot better than PS4. I set the video output on PS4 to Auto and let the Eizo handle the conversion process. If you try it, you will notice eizo gives much better processing than ps4. Limited range set on the Eizo and auto for ycbcr and rgb range, the picture looked absolutely spectacular on the eizo. Now that's it's gone, picture is degraded. Sony said they will bring it back next patch, so I guess I'll have to waut. Thanks for the r3commendayion, I'll give it a try sometime.

Honestly, sounds like you just had the settings mismatched and were crushing blacks, which leads to a darker and more saturated picture that makes the correct picture look hazy in comparison. If you like that look you're better off setting it up correctly and then raising the gamma to 2.4.I don't have a technical explanation as to why there is a difference when y/pb/cb/prcr was taken out since I don't know much about video processing, but I can absolutely tell there is a difference. I don't have the time right now to look into it in detail but I'm sure there is a technical explanation as to what my eyes were seeing if i ever decide to look into it in future. The richness, depth, and contrast all looks degraded and anti aliasing also looks like it's been turned off. This is a dissappointment and very very annoying. For starters, just by the general look of things, since there was a ycbcr option other than rgb to begin with, I suspect they are 2 different individual signal and conversion/processing, and not 2 are the same - therefore would result to different outcome of picture. I just don't understand why they would take this option out when every HD player and PS3 still have it in their menu. Atleast have the option there where users can turn it off or on. One other thing I do notice is better framerate in games when ycbcr etc. option was taken out, but not worth the degration of picture quality imo.
