There are enough 4K 240 Hz OLEDs in my database to field a full group for the PA32UCDM’s comparison. The others are Asus’ PG32UCDP, Acer’s X32 X3, Dough’s Spectrum Black 32, Aorus’ FO32U2P and HP’s Omen 32 OLED.
Pixel Response and Input Lag

The response test puts all screens on an even playing field. 4ms is what’s expected from a 240 Hz monitor, regardless of resolution. The PA32UCDM delivers the same smooth motion resolution in moving patterns and content as the other monitors.
In the lag test, the PA32UCDM is behind the HP by just 1ms, an imperceptible amount. It is therefore one of the fastest 4K OLEDs currently available. It may be a professional reference monitor, but it can game with the very best.
Now, about the Adaptive-Sync at 120 Hz thing. I noted that limitation during testing, so I added a few observations to see if it really made a difference. The Nvidia Pendulum graphic includes sliders for minimum and maximum refresh rate, so I tweaked the max downward to see when frame tears would appear. They didn’t happen until around 100fps, which means you won't see any tearing even when limited to 120 Hz. That is not to say there won’t be blur. That line is a bit higher at around 160fps. However, I could clearly see from this test that Adaptive-Sync is not needed above 120 Hz. And that tracks since that is the limit of today’s gaming consoles from Sony and Microsoft.
Test Takeaway: The PA32UCDM may not have dozens of video processing options like other gaming monitors but it is no less capable of delivering a premium play experience with smooth motion and very low input lag. Though you can buy a less expensive 4K 240 Hz OLED and get the same video processing performance, none will have the PA32UCDM’s high-end look and feel, or color precision and flexibility.
Viewing Angles
I’ve noted slight color shifts from other QD-OLED monitors due to the extra screen layer involved but the PA32UCDM does not show this trait. It looks almost identical at 45 degrees to the side as the center view. You can see that it’s a tad warmer but only if you look hard. Brightness and gamma do not change. The top view has slightly lower (lighter) gamma, but it too is largely the same as the direct view. This is excellent performance that is a bit higher than other OLEDs.
Screen Uniformity

The PA32UCDM posts an average result in my screen uniformity test. It’s well below 10%, the visible threshold, and I could not see any hotspots or artifacts in a 10% field pattern. This is as it should be for a high-end reference display.
