While I believe you have the monitor back already, few thoughts, because I had to use Benq and Repairtech RMA process again these days.
To realise how fast their turn is.
a) Filled the email form reporting the issue with the 2730Z on Wednesday (two days ago)
b) Yesterday a technician asked me to check few things with the monitor.
c) Last night when I went home, replied to his email.
d) Today RMA process is ON and my replacement monitor is already with the carrier to be delivered on the next working day. (monday).
Had I contact them on Tuesday or Monday, I would have had my monitor replacement today or yesterday.
And since I was checking my email history with Benq & repairtech.
When had to RMA the monitor again for same issue, the process was again two of working days until the carrier was due for deliver the "next working day".
(Reported the issue Monday and Thursday had the replacement monitor).
When asked them to update the firmware back in June 2016, they picked the monitor Friday, and had it back on Tuesday.
In my opinion Benq and Repairtech provide the BEST service around here.
And if the refub monitor goes pop again, and I am out of warranty, I will buy again a BenQ product.
At least I will wont have to face some horrific stories you hear about the likes of Asus.
