high or low black level?

NAMAJAFF · April 28, 2023

I'm using the lg cx and while browsing the settings I found the black level setting. auto defaults to high but I tried low and it looks fantastic. but the thing is that my pc is using full RGB (or something like that, anyway the "correct" setting should be high), and I used this website to check if high is the correct setting and it is. is it that I just have shit taste or is there something about it?

it's not that the image is better, the high black level gives me super washed-out images when playing dying light 2 at night, and the low black level fixes that (basically on high black level which should be the correct one dark rooms look grey. low black level looks dark as it should be)

I'm honestly just confused if I should leave it at low or if that's a mistake.

I use Low on all my LG monitors as it looks better!!!

2x LG 24in on my workstation, a 22in LG for CCTV, and just got an LG 29in Wide 2560x1080 HDR10+

Unless I edit video or photo then I use the MacBook as its Colour Accurate.

Low Blacks ALL THE WAY EVERY DAY!!

I set mine to high for my PC when my PC always display at full RGB 4:4:4. Other than that, low is intended for limited 16-235 and auto determines whether the source is full or limited.

I kinda get where you're coming from, low can fool me to make the picture look 'better', but it did made dark scene too dark and changing back to high would fix it.

When I manually calibrated my C1 to suit sRGB curve using 22-point White Balance, it fixed dark level issue but it also made the colours less pop. So I made second profile to suit Gamma 2.2 curve to have saturated colours back & darker scene. Then I can toggle sRGB for most contents while Gamma 2.2 for cartoons.

At the end of the day it's your TV, you can set anything you like for better enjoyment. My friend don't like 6500k colour temperature and preferred 'bluer' white, that's fine too.

Limited looks better if you run your desktop in hdr. But if you have your nvidia card or amd card set to full, and you tv set to limited, it might look better/deeper more colorful but you are cutting signal and losing it. Its really meant for you to run full from video card and then full on TV. Like I said, it might seem better but you are losing signal.
