Effect of dimming the display?

I’m in the habit of using the Dim button on the remote to dim the displays on my PS Audio gear while listening. I do this mainly to prolong the life of the display. I also find it less distracting at night not to look at the blue glow.

I have read that displays are electrically noisy. Does using the Dim button actually turn the display off (which might reduce noise), or are the displays just not visible but still active?

Magister, I’d also be interested in the answer. If nobody knows, you could call PS. Someone there should know the answer.

FWIW a post on the topic from Ted

P20 & P15 Regenerator Performance Tweaks and Digital Stream Enhancements, plus BHK Preamp

Displays are always noisy. In the DS turning it off (using the Dim button) makes a noticeable difference. I expect that it will on the P20 as well. I always run with the display “dimmed” on both. Most displays require voltages other than just 5V so there is usually some switching regulator to generate those voltages which will radiate and also cause noise on the input power. The speed of the dots turning on and off is high enough that there is radiation from the display driver. The loops i…

Thank you Ted.

Ted, I presume your answer also applies to the P12 (which I have)? And what about the much smaller display format on the new Steller Gold DAC?
