BenQ monitor: turns off on its own + takes a while to restart/power on

[Ghastn]

Hi,
I bought my BenQ XL2411Z a week ago and it has been working fine until today when several display modes started causing it issues (plugged into laptop: so laptop screen + BenQ monitor)
For example, when I try to switch to "Second Screen only", it displays an "Out Of Range" error message.
However, the worst is when I try to duplicate (instead of extend) the display. It simply crashes? I cannot turn it on anymore and after 15 mn of screwing around it finally powers on.
I just tried to use HDMI instead of VGA and it looked fine at first but then the image became red then disappeared? It got turned off and I had to unplug for a minute before turning on again.
Any ideas what could be wrong? I am flying abroad tomorrow, so I won't be able to use my 30-day free returns from Jet.com (where I bought this from). I wonder if BenQ's warranty could take care of this or if a simply Firmware refresh could fix this?

Thanks,

Hello, if you still have warranty support then you should RMA it. It's possible the problem is internally, if it's not the power cord, so I wouldn't waste any more time and try to get a replacement!
