I FOUND A FIX FOR HDR ISSUE ON PG39WCDM

[scarecrow420]

I bought the PG39WCDM last month on a good sale from Newegg. I was very excited for it but once i got it and installed, I was very disappointed in HDR looking terrible out of the box. The SDR looked like how HDR should look. I ran with SDR for the month and it was fine but i didn’t buy this for SDR. Now i know with OLED monitors it requires some tweaking but this monitor wasn’t just a simple tweak. No matter what firmware, color profile, and other HDR settings i tried, It would look super washed out and terrible. Tried looking for a fix everywhere but everyone was either saying they are waiting on a firmware fix or just returned the monitor. I then thought about the Nvidia control panel and my prayers to find a fix were answered. If anyone is having troubles with the HDR here's what you need to do to get it looking how it should’ve in the first place

Steps i took:

Updated firmware on monitor

Reset all settings on the monitor

Go into windows settings and turn on HDR

I then went and downloaded windows HDR calibration. Calibrated with these numbers 0, 700, 700, and 80 on the HDR slider. (Tweak to whatever works for you but this works for me)

Go into Nvidia control panel and go into adjust desktop color settings

I put my settings to 60% brightness, 100% contrast, 1.00 gamma, 60% digital vibrance, 0 hue (you can tweak settings however you please but you might need to calibrate the display after again)

*MIGHT NEED TO GO INTO WINDOWS HDR SETTINGS AND ADJUST THE SDR SLIDER AS I HAD TO CHANGE IT FROM 100 TO 80*

Screen now looks like a proper OLED monitor.

Hi @scarecrow420 ,

Regarding your inquiry, we would like to inform you that we previously received user feedback about color banding and abnormal skin tones when HDR is enabled. The team has addressed these issues and released a new firmware version MCM103 on January 15th this year to fix them.

Could you please confirm if your current firmware version is 103? Additionally, please provide a photo of the distorted image with HDR enabled and a normal image in SDR mode for our reference.

We greatly appreciate your understanding and cooperation.

Thank you.

@Aureliannn_ROG  The firmware update made a slight improvement but didnt fix it all the way and a lot of others have claimed the same. Good news is I was able to fix HDR via windows HDR calibration and NVIDIA control panel as stated in my post :). I have provided some photos and hopefully you can see the difference. 

Here's some photos for comparison 

This is the stock SDR settings:

I'm on firmware MCM103

This is my custom fix for HDR:

you should test it see it if it works properly on HDR videos , i've done the same thing today on my PC and got good results the thing is i play on console , there is few asus monitor out there with HGIG which improves the colors , contrast and the brightness ,from my understanding asus lacks of knowledge in making HDR monitors no matter which one you buy , OLED , Edge lit , WOLED it doesn't matter they use Gamut color P3 without any other HDR formats like dolby vision , HGIG ...except the one specifice monitor (XG43UQ Xbox edition does have HGIG)

having control over brightness and colors could fix the HDR with little increase in brighness , contrast and color

the thing is they don't like it ! they force you to use sRGB with super low brightness  and calling it HDR ! they don't even asnwer my topic .

not everyone playing on PC i have an 4050 RTX not powerful enough for 4K gaming and HDR sucks on console ! their customer service is online and they don't answer to me

I will try console when I'm next to my setup again. I know for console there is no ultrawide support and so it stretches the image and doesn't represent actual quality. Console uses 16:9 ratio. ASUS does have some terrible HDR profiles but might not be so bad with console and a 16:9 ASUS monitor. But for 21:9 like the PG39WCDM console is terrible. I know youtube HDR videos and movies look good tho not as good as TV even with my fix applied but i don't know about console.

i can confirme the HDR in cheap TCL TV does looks better than this i could've buy QLED TCL for half of the price of this monitor

for HDR content people should stick to sony , LG , TCL brands

buying a OLED monitor from ASUS is waste of money

Hello Asus Forums,

That’s awesome that you found a fix! HDR issues can be super frustrating, especially when a monitor doesn’t deliver as expected right out of the box. Tweaking settings in the Nvidia control panel is a great tip—sometimes, the right adjustment makes all the difference. For those looking to enjoy their newly optimized HDR experience, I’d also recommend checking out sites like netmirror to truly see the full potential of your display.
