Hello, by far i didn't had any problems, i use it for cad design and I'm happy with it.

Found no issues at all with my BenQ. Very happy with it.

I was goign to buy the new out of stock/updated version PD3220U but your older model at CHF450 cheaper is very tempting, hmmm.

Never had a flicker issue
and sometimes I use the monitor paired with a 25" 2k Dell... so even with different resolutions 0 problem at all
