ASUS RoG Swift PG278Q coil noise/whining

[Shadowsken]

I recently purchased one of these screens as I've heard great things about them, but mine has this horrible high-pitched whine coming from it at all times when the display is on; I first thought it was the included power supply but the noise is coming from the actual screen. It increases in pitch and volume as the brightness is changed; so it's quietest with the brightness set to 0 and very loud when at 100 (can hear through my headphones when in use).

I've been in touch with ASUS support but I have to wait until they open office again on Monday so I was wondering if anyone else had encountered a similar issue, or had any measure to solve the problem. Thanks.

It... kinda happens.

I have an Iiyama 1440p monitor that's supposed to be very very high end, and it squeals like a violated pig as soon as the brightness goes above 0. This tends to be because of cheap caps used in the power supply circuitry, which means you have a couple possibilities to fix it - both of which, unfortunately, involve opening up the monitor and breaking your warranty.

1) You can open it up, find any components that may be squealing and are poorly insulated, and surround them with hot glue. (No, seriously.)

2) You can try to isolate which caps are too weak, and replace them with far more expensive, very high-quality capacitors. This is the better option, but requires you to be handy and confident with a soldering iron.

Definitely do everything you can to talk with Asus before breaking your warranty, though.

I've known electrical goods to whine before, but this is obnoxiously loud. I can't have the screen brightness above ~20 because my housemates can hear it through my closed door, while I get it assaulting me through my headphones. Definitely going to get ASUS to do their thing because this is clearly an issue.

Oooh, yeah, that's really bad. Certainly should be to the point where they should do something about it.

Usually if you complain about coil whine you just kinda get brushed off.
