RGB or YCBcr422? (New TV)

djshauny1 · 11 Jun 2018 at 19:50

Hello everyone,

I recently purchased a new TV (a Samsung ue50mu6120) and Im unsure what I should use when using my PC and PS4 with it.

Link to the TV http://www.samsung.com/uk/tvs/uhd-mu6120/UE50MU6120KXXU/

Do I use RGB or YCBcr422 on the PC/PS4? I cant get the picture looking right.

Any help would be great. Thanks.

Generally speaking, RGB limited is best.

On my TV do I need to set the black level at low or normal?

Are you not able to select YCBcr444 or RGB Full?

Yes I can select that but Im not sure if my TV supports it. Two samsung support reps have said different things lol.

Well if they can be selected, quite likely they are supported. Try them and if it doesn't appear any worst than other options, then use it

I am not sure what your TV does to blacks under low or normal. In this case best to leave it to normal. I suspect 'Low' will brighten up things at cost of poorer black levels. See what pleases your eyes.

for blu-ray playback you are better going ycbcr, since blue ray encode is natively that, and players make errors converting to rgb
I had bookmarked this showing OPPO RGB errors

for PS4 (maybe it was xbox), i had thought they internally convert everything to rgb, so rgb is the best you can get out of them, silly to ask it to re-convert to ycbcr, giving further errors.

Well I don't know much about your specific TV

But I imagine that:
RGB Limited should be Black level low
RGB Full should be Black level normal

From a PC you'd really want RGB full and normal black levels anything else will look odd.

It's the same thing, it doesn't make a difference on PC.

With consoles in the mix it does though. I'm fairly sure the Xbox doesn't even support RGB full for instance, so then the TV would be washed out unless you were using a different HDMI input that had its own settings.

When I set the black level to normal everything looks kind of washed out. Any suggestions? Cheers.

your tv must be interpreting signal as full rgb, if it is limited range from pc/ps4 then black is 16, but for a tv on full 0-255, 16 will be lighter/washed-out.
... so look for an adjustment on the tv.
