You may not notice PWM right away as you will be too busy enjoying that drop dead gorgeous display, but I started experiencing eye strain after using it for a few days. Did some research and found out about OLED PWM flicker. I experienced eye strain even though I use phones with OLED panels, which was surprising and disappointing.

The main issue with this model is that the PWM starts below 50% brightness and the frequency is a bit low which can cause headache to people sensitive to it.

Ended up with the 14p Gen 2 with 2.2k IPS instead and feel better. The OLED was gorgeous, but man I was scared of burn in. People say not to worry, but I didn't want to chance it especially with all the static stuff in windows, office and games. Prob shouldn't have to worry anymore, but I'm happy.
Got the 5800H now…Miss having the 5900… for reasons 😅
Currently the only 2880x1800 14" 90Hz OLED Panel is from Samsung and the model is Samsung SDC4154. The main issue with this panel compared t 15.6" 4K Panels are the lower PWM frequency which is 300-360 Hz and gets triggered below 50% brightness. Asus VivoBook Pro 14/14x use the same Panel there are multiple reviews available for that. It is highly unlikely that all the review channels like NotebookCheck, UltraBookReview did make that measuring mistake.
That definitely doesn't look like DC dimming like the monitor behind it. Whatever it was, it was very noticeable next to a non OLED display (desktop monitor and another laptop I have), and it was leading to eye fatigue over extended periods of use. I was so bummed about it too. It was such an incredible laptop in every way, but I just couldn't keep something that could cause eye strain if I stared at it for hours every day. Very very disappointing as I absolutely love OLED displays on phones.

Varry Bright basically try to adjust the display qualities like Brightness, Contrast, Color Modes (sRGB, DCI-P3, aRGB) dynamically and it can affect your display's quality to a big way, especially in battery mode. Even if you trying to reach the max brightness, it won't allow you to reach that and will try to down it back. In LCD Displays, the image looks less sharp with poor contrast. Nor for OLED displays, that may be behaving a bit differently.
