Uncalibrated – Maximum Backlight Level

The PA32UCDM is an exceptionally bright monitor among OLEDs with a 1,000-nit capability. This can be measured using a 3% window pattern. I use 25% and was able to see over 706 nits, so Asus’ claim tracks. This is with Uniform Brightness turned off in the Natural preset. Otherwise, the peak is around 250 nits which is plenty of output for SDR content in a moderately lit indoor environment. Like any OLED, black levels and contrast cannot be measured.

After Calibration to 200 nits

The brightness slider has 400 possible settings and suggests that its value will match the actual output level. It’s close but not quite. I found it was offset by 11 to 84 clicks, depending on where in the range it was set. With Uniform Brightness on, 284 was right at 200 nits. Each click is less than 1 nit so it’s possible to dial in very precise levels. Black level and contrast measurements were not possible for either static or ANSI (intra-image) values.

Test Takeaway: The PA32UCDM adds flexibility with its Uniform Brightness toggle feature. For SDR and workday content, the 250-nit peak is plenty of light. For video and HDR material, 1,000-nit peaks mean lots of dynamics and punch to the image. It’s great for gaming and movie watching.

    No Displayport? That's just weird to me.

    Is it possible to use a usb-c to display port adapter backwards to plug in a graphics card to the monitor? A single HDMI input and no display port is a real PITA for those of us with normal graphics cards that also want to plug in a gaming console.

    I've read the gaming sections of this review twice. I bought a new PC for Lightroom and flight Sim 2024, Hunt Showdown and Age of Empires with a 9800x3d and 5080.

    I'm wanting a monitor to photo edit (hobby enthusiast) and game.

    Given adaptive sync cuts at 120hz but I may able to achieve above this. Will I get screen tearing or any issues. I've only ever known my 165hz 27" that supports gsync to the refresh rate limit of the monitor.

    Is this something they can update with firmware. Guessing it's a limit of the HDMI port.....wish they included display port.

    Basically should I buy this or get something like the Gigabyte Aorus fo32u2p or PG32UCDM??

    No bling advert.. coff review will shake the fact this product is a utterly fail at this price point. No monitor justify costing more than a grand, even $600 for every other 32 inch OLED is kind of too much already. And you know, 32 inch is such a dumb size l, c'mon. It's 27 for 2k and 40 for 4k, in between is dumb. Just give it another resolution if you want to sell it at 32

    Thought I'd come back and say I decided not to go with this screen and Bought the Gigabyte Aorus FO32U2P which RTINGS had as a great gaming and photography monitor.

    Asus did a big fail not making this a proper use for color critical workers who also game in the offline at home. All they had to do was add DP1.4 (or 2.1) and add features from their 32" PG32xxxx gaming line and it would have been a home run.

    Asus support on the phone told me VRR 120Hz cap is a hardware limit and won't be able to go to 240hz in future firmware updates.

    Plenty of us gamer dads are willing to pay slightly more for something not so RGB crazy in their office. Hopefully in the future they add a DP port and VRR through to the max frame rate of the monitor.
