"Some surface-mount capacitors exhibit acoustic noise when operated at frequencies in the audio range." [1] I see that this screen has alternating black and white lines. I count 43 black lines on my monitor. Assuming 60 Hz refresh rate, that is 2580 Hz in terms of the pixels being off or on, which is a perfectly audible frequency. Even with 120 Hz refresh rate, that would be 5160 which is still easily audible. Withou…
I mocked up a quick JS canvas page that varies the bar width and I do indeed hear the tone changing: http://thume.ca/screentunes I also put some ideas on the Github Readme including using feedback from the microphone to calibrate a width->pitch mapping to play music using your screen.
Hey, I forked your repo and added tuning, so that everyone can adjust it for their display

Maybe I'll get to get it play music (a json with timings and notes would suffice, I suppose?)

That's so cool! I can hear it on my Nexus 5 if I put it right up to my ear!

#144This somehow manages my monitor to make a high pitched sound. It's an LCD monitor. It's the actual monitor making the sound. Switching to a different window or tab makes the sound top. Taking a screenshot of the tab, and closing the tab but viewing the screenshot, produces the sound.
I recently tested my new TFT (TN-panel) monitor with a monitor test application, and noticed an high pitched sound on a very specific blue line pattern too. I turned down the brightness from 100% to 80% and that reduced it.

#146Nifty. This effect reminds me of the old-school color cycling animations that 8bit games from the 90s used to have. Someone actually made a canvas viewer to show off how it works: http://www.effectgames.com/effect/article.psp.html/joe/Old_S...
Ah, palette shifting, that takes me back... but man, Mark J. Ferrari, truly a master in the 8-bit field. Really took palette shifting to another level. And the site does a great job exposing what's going on under the covers. Great link!

Hey, I have done some work on my fork, and now it plays NYAN CAT (didn't have any better idea...)

You have to calibrate it before it starts playing.

Inductors do this as well. The changing magnetic field causes the windings to vibrate, creating an audible sound. The sound my work monitor makes sounds like an inductor to me.
The power supply on the old Apple II "chirped" when switched off. I always understood it to be the oscillator decaying down from 20 KHz to DC in half a second or so.
