Uncalibrated – Maximum Backlight Level
The PG34WQ hits about 305 nits in SDR mode, which is plenty of light for any work or gaming application in an indoor environment. There’s more output available for HDR content, nearly 500 nits, so the headroom is there.
The default black level is great compared to an IPS monitor but a bit below average among VA panels. That limits contrast to 2,219.3:1.
After Calibration to 200 nits
Calibrating the RGB sliders and turning down the contrast slider from 50 to 35 makes a huge difference in image quality. I still wished for darker gamma, but the contrast increases to almost 3,100:1, which helps with depth and color saturation.
ANSI contrast stays consistent at 2,886.4:1, a solid result. Though the other VA monitors score higher in the contrast tests, the PG34WQ delivers decent quality. A darker gamma would move it up the rankings.

digitalgriffin Looks like I bought the Dell version of the WQHD 34" a little too early.Reply
To be honest I am really unhappy with that monitor. In HDR mode it's colors are horribly muted and dull even with the custom monitor profile. My sons happy with it and it's his monitor so I kept it. But man, what a let down for a gaming monitor.
