If you are looking into Dell’s professional workstations, then you might have already come across the Precision 15 3520 – a durable workforce on the go that has a lot to offer and has little drawbacks along the way. Unfortunately, one of the cons is the presence of PWM from 0 to 99% screen brightness.

We are talking, of course, about the configuration with IPS display and that’s pretty important to note since this is a business-grade laptop, which will probably be used for extended periods of time. However, the good news is that the panel flickers at pretty high frequency – 21 kHz. This will most probably affect only users with extra sensitive eyes and only between 0 and 99% brightness.
If you are looking for a safer option, though, consider checking our PWM ranking, which ranks the laptops we’ve tested in terms of health impact.
