I’d like to share my experience using this monitor.
I bought it a year ago, looking for a bright HDR monitor with excellent color reproduction.
It’s the best monitor I’ve ever owned; the picture quality is simply superb!
I chose a mini-LED instead of an OLED because the OLED isn’t as bright and burns out.

This is a 32-inch 4K monitor with true 10-bit, 60Hz resolution. There’s a 120Hz model in the lineup, but it’s more expensive.
It has a mini-LED backlight with 1152 zones, and the measured brightness in HDR mode is around 1500 nits with a full white background! Moreover, the monitor can maintain this brightness for quite a long time. There are newer models with 2000 and even 4000 backlight zones. Because there aren’t many zones, you can sometimes see a halo effect; for example, when a bright object is on a black background, it’s usually invisible. Personally, it doesn’t bother me much. With more zones, this effect should be unnoticeable. This is one of the minor drawbacks.

Color reproduction out of the box is excellent in both SDR and HDR modes, with a 90% Rec. 2020 color gamut thanks to quantum dots, allowing for very rich colors. The monitor has built-in memory for loading 3D-LUT calibration data directly onto the monitor. Local dimming can also be used in SDR mode, producing deeper blacks. I always have it enabled. Color accuracy in dark tones and shades is excellent. There’s also support for VRR mode.
There are several good reviews of this monitor online, and everything about it is good. Personally, I don’t like one thing: the built-in fan.

The fact that it’s there doesn’t bother me. On the contrary, it’s good that it’s there, but it’s small and noisy, with multiple rotation speeds. The only thing that bothers me is HDR mode. In normal mode, it either doesn’t turn on or runs very quietly, even though my SDR mode is calibrated to 250 nits.
I don’t understand why they couldn’t have implemented proper heat dissipation. ASUS could have installed 2-4 large fans, 140-200 mm, with fluid dynamic bearings and a large aluminum heatsink, which would run very quietly.

If I enable HDR mode in Windows and work in Word or File Explorer, after 20-30 minutes the fan turns on at quite high speeds, even though the white on my desktop isn’t particularly bright. In normal SDR mode, the white is brighter, and the fan doesn’t turn on at all. I don’t understand why this is so.
I want Unscrew the back cover of the monitor and see how it’s arranged inside. Maybe replace the fan or add your own, or make some modifications.
I need help removing the back cover correctly?
There are no screws. I watched a video online, but monitors are designed differently there.

Thanks for sharing your review of the ASUS PA32UCX-PK. I’m glad you’re enjoying it so much! The PA32UCG (a 120Hz variant) has been one of my longest-standing recommendations for colour-accurate work. Unfortunately ASUS never had any review samples they were able to provide for testing, but I’ve used it at trade shows before and have received a lot of positive user feedback.

It’s an interesting observation you made about the fan running at high speeds under HDR regardless of brightness level. You’d expect there to be a temperature sensor element to that rather than what seems to be a pre-planned ramp just because the monitor is receiving an HDR signal. With respect to tearing the monitor down, it’s not something I do myself so it may be worth getting in touch with Simon Baker over at TFTCentral to see if he can assist with that.

The fan doesn’t always work in HDR mode. It has three speeds: barely audible, medium, and like an airplane turbine)) The latter turns on when the monitor overheats, prompting a message to appear on the screen. I’ve only had this happen twice.
The medium speed is quite noisy, which is why I don’t like it. The monitor has a sensor, and the fan turns on and off periodically. I’d like it to be less frequent in HDR mode(

Thanks for the recommendation
