Question / Help Full Range vs Limited Signal Path

[jesyjames]

So I'm using a magewell 4k capture card.. I have a 1440p mirrored full range rgb signal going into capture card from HDMI out on graphics card. Now if I am in OBS and go into the properties I can change the YUV Color Range from Partial to Full. I can also do the same thing in the advanced settings of OBS and toggle between Partial/Full. Do I set both the same? One to full, one to partial?

Is there a correct path? Does the source factor in at all? What got me wondering is on my PS4 when I capture that I have the TV set to full and the PS4 set to full otherwise it looks wrong. But then on the capture card do I set that to full? Do I leave one at full and another at partial?

I read somewhere that video players typically assume a limited signal but I don't know if OBS converts everything to the correct range or if information is being lost. Hopefully someone can help. Thank you.

If you have the option to give full color range to your feed on your Capture Device.

ex. Color Range 0-255 on the LGP or something along those lines.

Then leave/set the Properties settings on OBS to 'Partial'...Partial in this case would equate to 'unchanged'...if you don't have such setting on your Capture Device & your feed looks odd to begin with...in terms of contrast/colors, then set the setting to Full on OBS.

TL;DR - If you have Full Color Range option on Capture Device, set it to 'on' & leave OBS Capture Device's setting to 'Partial'.

'Video Capture Device' properties YUV Color Range specifies type of the input video color range (how to decode it).

Settings>Advanced Settings, YUV Color Range : specifies color range for encoder's input (how to encode it).
