I thought I'd share my experience with Asus support on getting mine swapped after it developed the fault. I put it on the back burner for a while since I bought an X34, but I've been playing more CS again recently, so the try-hard in me needed the swift.
Anyways, the RMA process itself was quite painless. One online form to fill in, a slight delay whilst I provided a video of the issue, and a swap on my doorstep was arranged in a few days (form completed Sunday, swap took place today). I was happy with that, until the replacement arrived today.
In the top-left hand corner, the panel isn't flush with the screen, it sticks out a few mm, none of the controls on the back work, the power light doesn't work on either the bottom panel, or the surround of the base, and the whole bezel has marks where someone has stuck a screwdriver in to wrestle the panel out.
On top of that, the "Light in Motion" option is permanently on the screen, and as the controls on the back panel do not work, I can't choose an option to get rid of the menu, rendering the monitor practically useless.
Shocking, SHOCKING quality control on the refurbs. I'm understanding where Asus support get their reputation from now.
I've emailed support, as well as the MD of Asus UK with a lightly worded, constructive email about my issues. No reply from either as of yet.
