So the night before last my monitor started making a sharp popping noise at a rate of about 1 pop per second that lasted about three minutes. After three minutes, the rate of popping decreased over a period of about 30 seconds until it stopped completely. At no point after this did the monitor make any more noise, and everything seems to be working fine.
I used it for about 3 hours last night and the event did not repeat itself.
The question is, should I return the monitor and seek out something else, or stick with it and hope that it was nothing? If Amazon were doing replacements, I wouldn't hesitate, but unfortunately they're only doing refunds on this particular item. So I'd have to order one from somewhere else for more than what I paid for this one (and risk getting a panel with problems ala dead pixels or unacceptable backlight bleed), or buy a different monitor. I have 1 day to decide, after that point it will no longer be eligible for return and I'll have to RMA.
What would you do in my situation?
