Bests & Worsts Reviews from Amazon

I've gone through two of these monitors now, both displaying the same problem (flickering in the top right and left of the screen, and developing dead pixels. Both units worked fine upon delivery. Acer support refused to honor the warranty on the replacement received less than 90 days ago from amazon (amazon replaced the first one no questions asked even though it was slightly outside the 30 day window). Given that I run an IT managed service provider, I will no longer purchase acer products going forward, and will advise my clients upon the same. It's too bad, I've used acer monitors for years, but I've only heard how legendarily bad their support is up until this point. Amazon has stated they will attempt to resolve this once I obtain a certified letter from acer noting the warranty is being rejected.
