Wife and I have two very large widescreen Dell monitors immediate adjacent in our study and they don’t particularly seem to upset the WiFi or Bluetooth or anything else.

It could just be a dodgy power supply or a degrading DC/DC converter within the circuit board (both which run at very high switching frequency) which is emitting the excess RF noise. Switch monitor off from wall and check?

When the mains power is switched off the noise stops. I have tried a different power cable to rule that out, and it's deffo from inside the monitor itself as that made no difference. If I turn the monitor to standbye/off from the monitors buttons (so it'll still have some small amounts of current whilst in standby) the noise also disappears.

I need to get my network cables terminated and use them. Only been dangling out the walls for nearly 3 years lol.

I thought I'd order a new digitally tuned radio from China to see if I have anymore luck with regards to this. This one works much better than the manual one I used before as I can set to 612mhz exactly.

612 mhz? Just over 0.5 Hz - that is rather low.

Unless you mean 612MHz - which itself if way above/below any potential interference an rado do not normally go to that frequency

Swap out the monitor? You could otherwise go wired network, but your other wireless devices, mouse etc would presumably still be affected by the interference caused by the monitor.

Presumably he meant 612 kilohertz (in the AM range). 612 MHz (megaHertz) is upper UHF band and 612 milliHertz simply makes no sense, despite the small ‘m’ shorthand used above.

612 MW is what my trusty Roberts is tuned to.

Yes Sir. 612 medium wave = 612 kHz (amplitude modulation)

It's not clear from your post but is this actually causing any problem? Do all your Wi-Fi and Bluetooth issues clear up when you turn this display off?

At the moment all we know is that you've found that a component in your monitor is putting out noise on a certain frequency, but that's all.

When shifting the monitor out of the office and using just the laptop screen the issue seems to go away for the mouse/keyboard. I am not totally sure yet if the problem is erradicated as the WiFi issues are mainly seen on my PC/server (which obviously needs a screen and it's where there appears to me micro interruptions rather than the signal is not usable. This means pressing F5 a lot.

Oh yeah, 612kHz (or 612KHz as the radio labels it) although i'm sure you all knew this

If ya say so ….. I just wanders round listening I does.

And if it sounds interesting enough the 444 meter comes out as well.

What does a 444 meter measure?
