To compare the PG32UCDM3’s performance, I’ve rounded up a group of 32-inch 4K 240 Hz OLED screens. These are all flagship displays. They are Asus’ XG32UCWMG and PG32UCDP, Acer’s X32 X3, Dough’s Spectrum Black, and HP’s Omen 32 OLED.
Pixel Response and Input Lag
Thanks to Nvidia, I’ve recently acquired a new panel response testing instrument, the LDAT or Latency and Display Analysis Tool. It’s a photosensor that attaches to the screen, and with the included software, it can measure real-time input lag and panel response. The latter test has changed for me because Nvidia’s tool measures a small square at the center of the screen, not a full field as I had done previously. That means the new results are not comparable to the old. The PG32UCDM3 measured 0.24ms from black to white in a one-inch square. As I accumulate more data, I’ll be able to chart and compare these values.
The lag test is comparable to what I previously did with a high-speed camera. The sensor connects via a USB cable to my test PC and includes a button that emulates mouse input. I can press it as many times as I like, and the LDAT software will tell me the average lag time. The PG32UCDM3 measured 18ms of total lag (mouse input to screen flash, averaged from 25 clicks), which is on par with the fastest monitors in the segment.
Test Takeaway: The PG32UCDM3 is a very fast display with lower-than-average input lag and the near-instant panel response endemic to OLEDs. There is no motion blur at speeds over 200fps. If you engage ELMB at 120 Hz, it is also free of visible blur with only a slight drop in brightness. The PG32UCDM3’s video processing equals the current state of the art.
Viewing Angles
The PG32UCDM3 has the barely visible green tint common to Quantum Dot OLEDs when viewed at 45 degrees to the sides. This is almost impossible to see in content, so it is a non-issue. There is no change to brightness or gamma, so you can share one of these with a friend if you like. The top view is a tad warm in tone with a 20% brightness reduction and slightly reduced gamma.
Screen Uniformity

I’ve seen excellent screen uniformity from nearly all the premium OLEDs I’ve reviewed. The PG32UCDM3 sits right in the middle at 7.21%. This is well below the visible threshold of 10% where you might see a glow. The PG32UCDM3 has none of that. The image looks perfect from edge to edge at all brightness and color levels.
