    I've got a Dell SE2717H that is occasionally going black for a second before coming back on, and it appears to coincide with the fridge compressor switching off (which it does with a popping noise).

    The fridge has done this since I moved in, and my last monitor didn't have the problem.

    Is it the fridge, the screen, neither or both?!

    Any help very appreciated!

    Ground issue perhaps?

    I've no idea. It's a head scratcher. Not sure if I should RMA the screen or ask my agent for a new fridge.

    How frequent is the issue? Could test by switching the fridge off for an hour or two.

    I have this at work on one of my two screens. It'll randomly go black for a couple of seconds.

    I would get a UPS tbh. It really doesn't sound good. Do you have your PC on the same supply?

    If it's a ground issue the monitor may think that the PC has been shut down, turning itself off.

    - Stick the fridge on a surge-protected strip
    - Wrap a the power cord for the fridge through a Ferrite Choke

    If that fails

    - Ferrite Choke for the screen too (power cable and video cable)
    - Surge protected strip for the screen too.

    Thanks for the input. I was going to try a new HDMI cable for the screen. I'll definitely put the fridge on a surge protector and see. The monitor already has one.

    I don't have any Ferrite Chokes. Is this something one can just add to an existing power lead?

    It is very infrequent. Coinciding with the fridge compressor which happens a few times a day. Not sure if I should still RMA the screen, as it may be very susceptible to electrical noise.

    I had this with my 4K display when I turned my A1 Amp on.
    After lots of fiddling and cables. I found the only fix was to use a thick insulated HDMI cable.

    2 other displays connected to the same PC gave no problems when using the same cables as I had issues with on the main display.

    I have now put a surge protector on the fridge lead. I can try a ferrite choke and thicker HDMI if that doesn't work. So far it hasn't happened, the compressor is running on the fridge as I type this. So, we'll see.

    Thanks for the advice, all.

    Having tried the above I can say that the monitor is faulty. It goes black in reaction to at least two devices in my home.

    Lamda-tek have asked me to return it at my own cost. I'm not sure about that, I've only had it a few days. Other retailers pay for return shipping on faulty new items.
