The PG34WCDN is the first 360 Hz WQHD OLED I’ve reviewed, so I don’t have a truly fair comparison group available. I chose the most recent 34-inch ultra-wides in my database, which run from 175 to 240 Hz. They are Acer’s X34 OLED, Alienware’s AW3425DW, Corsair’s 34WQHD240-C, AOC’s AG346UCD, and Gigabyte’s MO34WQC2.
Pixel Response and Input Lag
I just started using Nvidia’s LDAT to test panel response and input lag, so previous response test results don’t apply. After testing one LCD and three OLEDs, it is clear that the OLEDs are far quicker to draw a one-inch white square, and the refresh rate doesn’t necessarily go hand in hand with the response time. The PG34WCDN drew the square in 0.24ms, same as the 240 Hz PG32UCDM3. But the 280 Hz Gigabyte managed the feat in 0.16ms. As I gather more data, trends will become more apparent.
In the lag test, the PG34WCDN nearly broke my database record set by LG and Philips. It hit an average of 10.3ms for 25 mouse clicks, which is incredibly fast. Competition gamers will want to add this monitor to their toolkit, as it has a clear advantage in input lag over the other screens. The 360 Hz refresh rate is the primary contributor to this result. I look forward to testing future 360 Hz screens to see what trends develop.
Test Takeaway: The PG34WCDN is one of the fastest monitors I’ve ever tested. Its input lag is well below human reaction potential, and it keeps the action smooth with very fast panel response. It is fully qualified for pro-level competition and delivers an addictive quality to gaming of all kinds. At this time, it doesn’t really get better than this.
Viewing Angles
The PG34WCDN is a Quantum Dot OLED, but I can’t see the telltale tint in this example. There is something to the RGB Stripe tech here that has eliminated any polarization. I’m being very picky here, as you won’t see any change at 45 degrees horizontal from any OLED showing real-world content. But it’s worth noting that QD and Stripe together are clearly a winning combination. The top view is a tad green in tone with lighter gamma but equal brightness to the head-on photo.
Screen Uniformity

OLEDs, including the PG34WCDN, continue to ace my uniformity test. Asus is last with a 6.64% average deviation, but that is still among the best I’ve seen from any monitor. It’s safe to say that with years of testing behind me, it is extremely unlikely that you’ll find an OLED monitor with visible issues.
