Video I did a while back
Had this monitor for three years, at 100% brightness no PWM but high pitched buzzing 
Unfortunately some days I can't handle the 100% brightness so I'm looking for a new 27in monitor that doesn't use PWM at all if possible (and the BenQ flicker free has some image ghosting I heard)
Filmed with CanonT5i at 720p@60fps using manual mode (allows shutter speed control). Seems slower shutter speed makes the PWM easier to spot (darker bars and all that)
That gets really bad at 0%.
Check out this link I posted: http://www.tftcentral.co.uk/articles/flicker_free_database.htm
They have some at 27" that are verified to not flicker. Using a U2414H (24") they checked and it's worked very well.
A embed media extension got created.. Let's see how it works..

Not too bad!

Not too bad!I have a decent camera. What are the best settings do you think for spotting PWM? Thanks.
Also, http://testufo.com/#test=blurtrail can be used to detect PWM.
If you can stand looking at the screen long enough to identify it :\
Bah I just use a slow enough shutter speed, works 100% of the time (unless it's very high frequency around 2Khz, at what point it wouldn't affect you anyway),

Spoiler of new video I filmed at best buy (MacBookPro 15in 2015 and iMac fine, bunch of shitty PC laptops with flicker 
)
SOMEONE HALP ME WITH THIS MIGRAINE AHHHHH
