im having a reslly hard time with the "black level" tv setting and my PS4 Pro.

Low is exactly the same as Auto. Zero difference, but High makes the colors washed out and puts this hazy filter on the screen that makes bright objects less bright, but putting it on auto makes the shadows too harsh and while bright light looks brighter, the dark shadows look too sharp and dark

Is there a happy medium? Why doesn't low do anything?

Thank you for any help!

Make sure the PS4 is set to ‘limited’ RGB level in its menu and not Automatic. PS4 = limited, OLED = Low will give correct results.

Sadly that doesn't do anything when I tried. Low is still exactly the same as auto. Both have shadows that are too sharp and harsh, while High is slightly washed out

But have you set the PS4 to Limited instead of Automatic for RGB level? The automatic setting does not work correctly and results in black crush.

Auto will be low, but the ps4 doesn't always do a great job at selecting the correct setting and mismatches the settings on ps4 and TV.

Select limited on PS4 and low on TV.

Then perform the HDR calibration setup on the ps4.

As others have said Low/Limited is correct.

There should be no difference in sharpness so I'm unsure what your seeing there.

Something else you could try is change the PS4 Pro video output resolution from 2160p-RGB to 2160p-YUV this is technically a degrade in 8-bit SDR image quality but its worth a try to see if you perceive a difference (LG actually processes YUV a little better than RGB).

YUV has no Low/High it is equivalent to Low only & all HDR output on the Pro is 10-bit YUV.

I should Clarify im talking strictly about HDR as that's all I play on ps4.

Then it should be on Low for both SDR and HDR.

Run the PS4 HDR calibration tool in its video settings and beyond that its TV game mode picture settings that you should be tweaking to your liking not any setting on the PS4.


Under HDR game mode picture options there are two other modes which affect HDR output;
HDR dynamic tone mapping - works on all HDR games but can alter output beyond what creator intended making some scenes darker and brighter.

HGIG - works only with compatible HDR games to optimize them based on the displays HDR capabilities, so doesn't alter the output too much but there are only a handful of games on PS4 Pro that support it.

Its a tough one. Sometimes the High black level makes the shadows less harsh and the overall picture has this pleasant filter on it and colors looks better, but in night or dark scenes its way too bright and not in a natural way , just looks like contrast is on to high. But in bright day time scenes with it set to Low the shadows can be really harsh and the overall shading makes somethings darker and less vibrant but on the plus side, bright objects are way brighter .

I dont know which i prefer tbh

I've been testing quite a lot on PS4 Pro on my CX last night, it seems that as of now (latest FW) Auto is perfectly fine on both, and actually the best choice.
When switching between HDR and SDR games, the TV mode changes (there are two profiles), it seems like the HDR profile defaults to low on both from auto, while on SDR it defaults to high from auto. Or something like that, but on both profiles auto seemed to be the correct one.

is this still confirmed? i read a lot of different things beause some people tested it and saw that best settings is "full rgb" and high blacks on sdr and low blacks on hdr

For SDR games the correct setting can either be RGB Full (PS4) and HDMI Black Level High (TV), or RGB Limited (PS4) and HDMI Black Level Low (TV). Either of those combinations will give exactly the same results.

For SDR video content the correct setting is RGB Limited (PS4) and HDMI Black Level Low (TV).

For all HDR content the correct setting is RGB Limited (PS4) and HDMI Black Level Low (TV).

The easiest solution is to just set the PS4 to Limited and the TV to Low for absolutely everything and be done with it.

Never use Auto on either the PS4 or the TV, it's broken.

You can use a different combination of settings if you wish, but your image will be incorrect.

thank you for the reply. low blacks on sdr looks awful tho. I did some tests and on sdr it definitely looks better with high blacks, as default in that game sdr mode by the way. for me they didn't gave me the same results. how come?
and who has the automatic mode broken? the ps4 or the TV?

Low blacks on SDR won't look awful as long as you have the PS4 set to Limited and the TV set to Low -this is literally how it is supposed to be viewed.

If you set the black level to High on the TV then that's also fine as long as you set the RGB to Full on the PS4. It will look exactly the same as Low & Limited; again, how it is SUPPOSED to look.

The above is for SDR games only.

SDR videos and all HDR must be set to Low & Limited or the image will be incorrect.

If you still think the above settings look awful and a different combination look better then that's fine, but, as I said above, your image will be incorrect.

I believe it's the PS4 that the auto setting is broken on however it's better not to use it on either the console or the TV just to be safe.

Set everything to Low and Limited and you will 100% have the correct image :)
