Really bizarre problem with my monitor. Wtf???

[starry]

So I have a Samsung S23C350 1080p 60Hz LED monitor.

When I flip the switch for the ceiling fan in my room the monitor flickers off for about 30 seconds??

Any ideas at all??

It's probably interference on the line voltage from the fan making its way to the PSU and through that, or perhaps disrupting the monitors PSU or worse the PC's PSU.

I have a pretty solid PSU, EVGA SuperNova 650w 80+ Gold.

Could that still be an issue through that?

I doubt it. It probably has to do with the wiring of your residence. My room light flickers when I turn on my stereo because my house is old with wiring from 1975.

Dirty wall power.

Time to throw down 60 on a UPS >.>

Thank you for the help.

Solid PSU with good filtering, so my bet would be the monitors PSU then. Could be bad wiring. I live in Ireland and over here we have laws saying ceiling lights must be on a separate circuit, however some countries don't stipulate that, or someone who didn't know what they where doing could have done the wiring. Also could be an old fan with lots of commutation noise, however a ceiling fan shouldn't use a commutator, more likely a reluctance motor, those can also produce noise. Consider getting an electrician in to check, redo the wiring or replace the fan with a better one if it annoys you a lot.

Just so nobody is confused, the MONITOR itself is not powered by your system's PSU.

Getting a UPS for just your monitor should resolve your problem.

The question is whether or not you have to get a UPS for your entire system.

Try plugging your monitor into a different circuit.

A USP would fix the symptoms but the problem would still be there, I'm not an electrician so I can't say for sure, and I'm  not in your house to tell either, but I doubt it's dangerous, but something to keep in mind if the wiring is more than a few decades old, it might be wise to consider getting new wiring, usually a painful thing to think about due to cost.

Simple solution is to have an electrician come check ur cables out... nothing wrong with your monitor its your wiring in the house/apartment that are faulty... in my current flat when i have 2 pc´s in my room and switch both on with a 10s delay.. power A on 10sec later power B on my room shutsdown... according to electricians its due to the "phase" for the room only supporting 1500w throughput... and its also linked with the kitchen according to them.. so having the microwave running / coffee machine and flipping on a extra pc = overload = shutdown the flickinging your experiencing is a drop of current in that socket which you have the monitor connected... i would have that checked out immidiatly !

I would totally get it checked if I had a way to pay for it, Im pretty tight on money but at least now i know how I would fix it. Thank you.

always though when there is a shortage of cash ;/ , you could try a different power outlet for your monitor while having the pc on another.. even if there are 3-4 outlets in a room most of the time they run on 2 diff phases
