PC Gaming@kbin.social – 1 points – I've just discovered that my monitor of the last 2 years (HP X27q) supports HDR 400. Not great, but an improvement over SDR nonetheless, I'd say. Only problem is, when I enable it, the monitor begins to emit a very high pitch whining noise. It's incredibly quiet, so quiet I didn't notice it for a few days. But now that I know it's there, it's definitely there and I can't go back to not hearing it. What in the world is going on with the HDR setting?
Id say it might be coil whine from the higher power draw. Coil whine is generaly safe
@Bandicoot_Academic Good to know that it's safe, but it is incredibly annoying. Do you know of anything I can do to make it stop short of disabling HDR?
It could be related with non official ink cartridges that you've tried to use in your HP printer.
Just a wild guess...
Coil whine my beloved
@aBundleOfFerrets Could HDR be causing enough of a difference in power draw to make it happen only when it's on?
Absolutely. Coil whine can be caused by other factors as well. You can find lots of ways to modify PCBs to remove coil whine online, but they will all be fairly invasive. I would recommend getting the manufacturer to replace it if possible.
