PG32UCDM Console Mode HDR issue

[FallenDeity]

My and other's PG32UCDM monitors have a clipping issue on PC when using the console HDR mode in Windows 11. Currently, the monitor clips at 450 nits in the Maximum Luminance window but it clips correctly in the Max Full Frame Luminance window. Is there a firmware update in the works for this or is this an RMA issue?

Surely others can tell you more.

In the setting description it is asking for "paper white" level. It also says it doesn't affect peak brightness. I think that is more up to preference. I seem to have it around 260 nits, but it depends on whether you want the game to look overall brighter or darker.

Anyway, game settings is definitely off-topic and not related to the original discussion.

Thanks for the input and apologies for being off-topic - just wanted to test the different HDR modes of the monitor, saw Alan Wake being referenced in this thread and wondered what settings people were using to test it.

The maximum brightness in game "should" be set to the max, that the monitor can deliver, and that is ≈ 1000nits in Console mode. 

Sure in real life scenes it can only deliver the 1000 nits in a 2% window. 

But the tone mapping of the monitor does "correct" the values for the monitor. So just set it to 1000 in console mode.

Or in cinema mode you can set up to 1200 nits without any clipping. Because in cimema mode the tone mapping goes all the way up to 1200 nits.

You can see that in "windows hdr calibration" tool.

Try it out, and you ll see that the monitor is "able" to show you 1000nits in console mode and 1200nits in cinema mode. 

Amd that are the values you should set in games as max.

Sure if you would measure the luminance with for real it would only be 250 nits and not 1000. 

The tone mapping of the monitor does map the 1000 nits down to 250

Appreciate the explanation! However, when trying out what you suggested, I notice that the in-game slider only allows up to 500 nits, even though it's correctly reading that the max monitor brightness is 1000 nits (set in the HDR calibration app). So, I'm not sure how that setting affects things, apart from changing the look of the game like @BiscuitJar mentioned.

I dont know Alan Wake...

If its a "paper white" slider then it its not the same as "max brightness".

And some games are a bit "special", has weird HDR Sliders, and or a bad HDR implementation anyway.

Then you have to set different settings.

But if a game has proper implemented HDR, then you should set the max brightness to 1000 (and if a paper white option exists, you can use paper white to make the overall image brighter or dimmer (sometimes paper white only changs the UI Brightness)).

So every game is different, and sometimes you just have to try around a bit, to find good HDR settings that work for you.

In Alan Wake I recommend to use 140 paper white if you are on Console HDR + boost (or Gaming HDR). If higher you will have clipping issues. For example your flashlight will overbright everything in close range.
But if you have just Console HDR leave paper white by default (or you can up the slider little bit)

Hi everyone!

Zigzag still remains on APL 25-100%. Will it be eliminated in future update?

Hi,

New Gaming HDR mode is too bright for me, my eyes hurt after few min. Console HDR without boost is my setting. Is it possible to set Gaming HDR and then reduce the brightness a bit?
