Hi,

My living room LG 4K HDR TV is connected to a GTX1030 in a SFF PC.

However, when the fridge or other electrical device switches on or off the TV black screens for a second.

I understand this is picking up the transient spike on the HDMI cable and the TV protection circuit is kicking in. I've seen it before.

The HDMI cable I'm using is a generic one that came with some monitor.

I checked on Amazon, but... Scamazon, lots of generic brands claiming better picture quality, which is ******** snake oil.

Is it safe to go with something like Belkin?

I don't want audiophooled or glitz ware, just a well shielded HDMI cable.
 
I understand that an HDMI cable, being digital is, it either works or does not work. However, HDMI cables are meant to be shielded. This is usually the first thing to be cut back on to profit. A cheap barely or unshielded HDMI will work fine unless there is electrical noise when it will just stop working. The symptoms are often black screen for a second.

The house wiring is fine and this is the second house I have seen this happen in. Last house was built in 2004. That time it was a Acer predator monitor, I left it undone, but it was solved when I upgraded the whole PC and used a DP cable instead.
 
Just wanted to point it the shielding works both ways.
If you have been plagued by that bzzzdupdupdupdupbzzzzzzzbzbzbzzzzzdupdupdupdupdupbzbzzzzzzz background noise on your headphones which changes when you move the mouse or open/close windows... ONE of the sources of that noise can be that your audio signal wire is running beside your unshielded hdmi cable.
Note I said "ONE" of the sources of that noise, there are others.
 
Also on wiring.
A fridge or freezer has a relay contact which fires the compressor motor. Even with starter windings or caps that relay contact will arc due to the high inductive load of the compressor.
If you had a radio turned on near by, like within 100m, you will hear a POP as an arc is just an omniband radio emitter and with several kW behind it any unfiltered reciever nearby will experience a loud (in radio) wide spectrum pulse.
Most things are not bothered, but a 4k display on HDMI cable is quite sensitive.
Remember Marconi's first radio transmitter was just a switch contact that produced an arc.
