Have a PG278Q. Beautiful screen, no backlight bleed, no dead pixels. It's perfect.
DOES seem that the Asus specced power supplies for this screen are a bit on the problematic side though (if you are ever interested, have a google, lots of returns etc).

I'm on my 2nd PSU and it's JUST starting to have issues (screen doesn't wake up/turn on. Have to take power lead out of PSU and plug it back in, screen comes straight on, no issues). First PSU this became a thing I had to do every time I came to use the system, this one... it's about... 1 in 10 at the moment.

Anyone had one of these screens and replaced with a higher spec PSU they could recommend a model number for?
 
I bought a generic "Asus F3S 19V 4.74A LAPTOP CHARGER" seemed to work.

The provided power supplies are definitely cheapest bidder jobbies - I surmised for awhile (its so bad) that they might have been what was causing those monitors to die as the ripple/regulation is so bad but further testing proved that not to be the main cause of the panel failures though might have sped it up a bit.

The whole lot is pretty shoddily put together monitor and power supply TBH takes the mick they market it as a premium product - after 2 dying (and the current replacement intermittently powering off at random so just sitting in my spare parts now) I cut my losses and bought the Dell S2716DG.

EDIT: Unfortunately I didn't upload the videos of it under load and when it was spiking really bad which was 10x worse - this is the stock PSU with no load:

Rather than just being the behaviour due to low load meaning it was out of regulation that is the behaviour of the PSU at its best.

replying to a fairly dead thread here but as my second Asus branded PSU has died. I ended up getting "
DELTA 90W 19V 4.74A AC ADAPTER LAPTOP NOTEBOOK CHARGER" assuming the delta is probably a good bet (assuming it's not fake :p )
