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?

So Asus create a Solution with the new fw for the APL brightness while creatimg a new problem. I think someone from engineering is creating himself an endless loop of work 🤣 What a Dejavu

Its ok... they do at least try something.

The people asked for moore brightness...

And Asus offered moore brightness now! Off course the tradeoff is loosing all details in the highlits.

But hey its bright now.

Maybe in the future they ll find a "middle way".

Yeah, it is inherit problem with OLED panels where the panel capacity is variable.

If you tell the game that "my monitor can do 1000 nits!" but in reality it can only do 1000 nits in very specific situations but in most cases is limited between 270-500 nits, now you have a problem when the game actually tells your monitor to "display these pixels at 800 nits and these other pixels at 200 nits" but the image has too high APL:

• The monitor can either render the content too dim and display those values at 400 nits and 100 nits (scaling whole image half dimmer than what it is supposed to be). This is how the original firmware handled it. HDR 1000 modes were all permanently dimmer.
• Alternatively the monitor can render the lower values accurately at 200 nits, and clip the too bright values at whatever the ABL limit is. This is what the new firmware does in cases where APL is too high.

Now, there is of course a 3rd option: The monitor could display the image at the "accurate" brightness when APL isn't too bright, but only adjust the brigthness / tonemap down when APL is too high. Then you get best of both worlds: Image that isn't too dim when the monitor can display it, and image that becomes slightly dimmer at darker parts when the image has too high APL for the monitor ABL to handle.

Or even better is just tweaking the tonemap curve at the 300-1000 nit range so that values within the "peak capacity" of 1000 nits are always mapped to the monitor output without clipping. This way the overall imge wouldn't have to get dimmer, only the highlights would become dimmer when APL is too high, but without visible clipping.

Optimal solution is probably somewhere between above two. Hopefully ASUS engineers can figure it out and don't give up because of all the complains.

I mean the screen isnt extrem bright its brighter than before but nowhere near an mini led whats understandable and yes a middle would be perfect.

I find the “General Brightness” to be a bit very bright now...

I have to set the "SDR Brightness" slider for SDR content in Windows to 0 now,   that the brightness corresponds somewhat to what I normally use my monitor in SDR

off course the highlits could ever use moore brightness in HDR... but i dont need 400+ nits overall...

You know that you are not supposed to have Hdr enabled all the time,especially when you are not playing games and just using windows and browsing the net.

I am playing Jedi Survivor today and i find the Hdr Console to be sublime.

In some games that use auto hdr like American Truck Simulator/Euro truck simulator there is some loss of detail around the clouds when the sun shines bright during daytime.

But any other proper Hdr game that i have played so far i feel like the Console Hdr mode is spot on,only needs some fine tuning.

I think many of you haven't experienced a bright Hdr panel before and you think that is way too much but actually it isn't..

This is how bright it should have been from the factory.

I know that... but sometimes i dont like to set it on and off everytime. So most of the time i let HDR just on.

And i dont like it this bright...

On firmware 104 i had to set down all paper white settings in games. Because it felt to bright for me.

I am just dont like bright overall images.

I like popping highlits, but the overall brightness low xD.

And dont tell me what a bright HDR Panel looks like! I have a PG27UQ (mini Led) that makes 1000 nits in full screen!

So i exactly know, how a bright hdr panel looks like.

But i still dont need it. 

My Pg27UQ is set to 10% brightness, and my pg32UCDM is set to 30% brightness (uniform brightness on).

I am sitting in a dark room and dont see a reason for moore brightness.

The only thing i like on HDR are small popping highlits. But i dont want to wear sunglasses in front of my monitor xD

I'm sorry i'm not trying to be a ******, but how hard is it to press WIN+ALT+B to toggle HDR on/off?? You don't need to go all the way to the Windows settings to turn off HDR.

Or is that even to much to handle.

You are supposed to have HDR enabled all the time, though.

Windows will render the desktop and non-HDR apps in SDR. There should be no need to disable and enable HDR manually.

[silverbolt81]

 No you are not because it messes with the gamma curve,windows environment is not an Hdr environment.. 

That's also  why in all auto hdr games the gamma is off and the blacks are always raised..
