Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I spoke to John over at Costco, he is one of the people I know that works there. He said people return mattresses all the time, they can be taken back within reason, time wise, is what he said. Didn't give me any specific time frame. They have large plastic bags they give you when you return...
I had the PB278Q before getting my Qnix. I bought a refurb, it developed dead pixels after a few weeks, I also got headaches from the PWM dimming. I have had no such issues with my Qnix.
I can tell you one thing about those, they don't overclock, if you are looking to do that. They skip frames using a higher hz, just like every other multi input monitor.
