Title: YCC or RGB?
Post by: JrPinto on April 28, 2025, 09:16:13 am

Hi, there!

What's the best option to set on graphic display software for JRVR: YCbCr ou RGB?

My TV is an LG OLED C3 and can handle both. But I'd like to set the graphic display the best way for JRVR.

Thanx in advance.

Mister Pinto, I think I understand why nobody responds to your 'question'...
Do you know what YCC and RGB stand for? If you do then your question is not for this Forum. JRiver Media Center has NO options for YCC or RGB.
JRiver has a great Support Team, ready to help someone who is using Media Center and wants to get the most out of the software.
Maybe you can find answers on one of the forums of Avforums.com, maybe you could ask LG or the maker of your PC about YCC/RGB...

I think the general consensus is to leave everything in RGB as that is the native color scheme for computers.  Since the processing chain for video can involve multiple steps, the idea is that you want to avoid conversion between YCbCr<->RGB as there is the potential depending on what is doing the conversion to lose precision.  It's like making successive copies of an analogue tape - every subsequent copy based on the last loses fidelity.

You have Windows, your video driver, Media Center, and your TV all involved in the chain to produce an image, and little insight (if any) at what exactly is taking place in the software as the video is processed along the way.  So best bet - leave it RGB.

Far more knowledgeable people can weight in here, but I think this topic - if you do some searching both here in the forum and elsewhere - will show many discussions that will drive you crazy, and has been beaten to death over the years.

For me, I run RGB/10bpc at 4K resolution on my LG OLED.  My video card is an nVidia 4090.

TheShoe, that was the answer I was looking for.

All I want is to have the most direct signal directly from JRiver to my TV. I´ll set my display card to RGB 10 bits, so as you do.

Thanx a lot for your polite and helpful answer.

I remember this coming up in the MadVR days and it was mentioned somewhere that MadVR immediately converts everything to RGB Full for all it's internal processing, so I've always kept the video drivers at RGB Full.  No idea if JRVR works the same way, but I've continued to use only RGB Full 10 bit and it looks great.
