Brightness and Contrast

Uncalibrated – Maximum Backlight Level
In our SDR signal test, the PD2700U easily beat its claim of 350 nits max brightness. It is a very bright screen, so you’ll want to turn the backlight to about half its range to achieve a more-comfortable 200 nits.
At max brightness, black levels were excellent among the other IPS panels here with the PD2700U showing a slight edge over its brother, the SW271. Note, the SW271 is a professional display and costs a bit more ($1,089 / £1,055 at the time of writing). Resulting contrast was an excellent 1,196.1:1.
After Calibration to 200 nits
Calibration to 200 nits brightness improved the PD2700U’s black level advantage quite a bit, though it still couldn’t keep up with the VA-based AG322QC4. We lost an insignificant amount of contrast when making our adjustments, but the slight gain in color saturation was well worth it.
ANSI contrast was strong at 1,010.2:1. Any IPS monitor that delivers over 1,000:1 in this test—a good measure of real-world performance, since the test pattern mimics actual content—is above-average. Our PD2700U sample would have performed even better were it not for a slight hotspot in the lower right of the screen.
