Uniform Brightness Setting on OLED Panel (Asus PA27DCE)

Dear all

I have a Asus PA27DCE (Oled) monitor, which i use as a reference monitor. There is the option of the Uniform Britghtness Setting, which is in my understanding supposed to tackle the issue with ABL on Oled panels. In my case, i only use the monitor in full screen, with my Ultrastudio 4K mini, so i am not worried about the image decreasing in brightness when scaling windows. When i work in Rec709 2.4, in the default calibration from Asus, the output is much brighter when the setting is toggled off, and vice versa.

When it is toggled off and the screen outputs much more brightness, i get the picture looking like i desire for an Oled Panel with decent brightness capability. When it's toggled on, the output looks much more like one from a low brightness LCD Panel and i would find myself pushing the highlights quite a bit to get a decent picture.

Now i guess it all translates what the viewing devices will be in the end. When i use the low brightness setting, i can much better adjust the exposure to be reflected properly on low brightness LCD screens (PC Monitors), but makes it much harder mastering it for High brightness TV's like my Samsung QE65QN90B with 1600nits. And of course again, vice versa.

I am normally delivering for the web, but currently also for broadcast.

What are your suggestions?

Thanks for any help!

Since you are working in SDR 709 2.4, calibrate the screen for 100 nits. On or off will likely provide a more accurate and stable image than the other. Use that setting. (I assume it will be "off").

Thank you for your answer!

I dont have an output meter to check what the nit-levels are and i would rather not recalibrate (in which case i could tune it with the Spyder/i1 Pro to 100nits), since i don't have a proper calibration software, that's why i wanted to stick to the out of the box calibration, which is supposed to be excellent.

Now that you mentioned the 100nits though, i did find in the manual of the Screen, that the "uniform brightness" setting limits output to 200nits. Now in the Rec709 preset of the monitor, the brightness is by default 50% which i assume translates to roughly 100 nits.

So i will stick to the "uniform brightness" setting on, and 50% brighness.

That is fine. That will work.

When you can and if you want to pursue color grading further, I highly recommend acquiring a colorimeter. That and calibrating software (there are free ones online), will allow you to calibrate your monitor. And the added bonus of providing a better understanding of some of the technical terminology of color science.
