LG OLED 4K TV -- RFI?

  • Question
  • Updated 2 years ago
I'm looking at the current series of LG OLED 4K HDTV sets (6B, 6C, 6G, 6E) and want to determine if they are known to generate RFI in the HF frequencies. Do any community members have experience with one of these sets in their home or shack?

We are facing the same questions ....

So I decided to purchase a i5 Intel NUK which was delivered today. It’s going to be my dedicated Flex PC. Step 2 is to use one 40” 4K TV as the monitor which should allow me to have the Flex software, my logging program and one other program on one large screen. I’m also wondering who may have already done this, and which TV’s are acceptable from an RF noise standpoint? I’d prefer Samsung as I have a close friend who works for Samsung and can get me a good price. LG sees to be the other company who offers small 4K panels.

I'd really like to hear how the NUK does as far as RFI.   Can it be powered by 12v DC?  I run everything here in the shack other than the amp off of 12v DC.

I don't have any experience with those in particular.  What ever display you decide on, just make sure it is capable of Chroma 4:4:4 sub sampling.  That's pretty important.  k6ozy has some pretty good info on the community regarding this.

As far as RFI goes, I'd be interested in hearing from anyone using any of these TVs as monitors for their Flex station.

I was going to go that route but a few months ago I decided to check for something I have been looking for at Good Will.   Geez am I glad I went in there.  I found a few 27" Dell HD monitors for $7.99 each.   Granted, these aren't very large, but they work really well and holy smokes $7.99 for HD monitor!   I couldn't pass them up.

Several people I know are using the NYC and there's no RFI issue I believe they run and 19 volts comments to follow

Runs very well at 11.5V - so the 12V battery will supply it well past normal drained voltage.  Used my 12V system on a NUC for years.  Watch for an increased current draw as the voltage becomes too low.  I won't post a voltage as YMMV significantly.

I helped setup a network and vpn on a NUC a couple of months ago. No RFI to speak of, at least not more so than ordinary PCs.

I'm concerned about interference from the TV not from the NUC

I own an LG 65EG9600 OLED set.   It is about 25 feet from my station and 80 feet from my main antenna for HF.   NO RFI at all on any band.   Only RFI warning is for the set its self in that it is a little sensitive to close by WIFI transmitting equipment and advise to place  WIFI equipment more then 6ft from the set.  By the way wonderful picture after full calibration.  

PS: Also use NUC with 6500, but installed with better PS.  OLD supply started getting noisy after a few months of use.

Thanks, Pat -- very helpful.  I'll probably purchase a LG OLED  B7 (new model for 2017) from the local Best Buy, which has price matching and a 15 day, no hassle, return policy.  Hopefully, there haven't been any significant changes in the power supply design that might generate RFI on the HF bands.
