Hello everyone!
I recently purchased the Dell Alienware AW2523HF monitor, and I couldn’t be more excited! Without a doubt, it’s the best monitor I’ve ever used. Issues like IPS brightness and backlight bleeding didn’t bother me at all. However, I did notice the dreaded coil whine, which made me wonder: is it just bad luck on my part, or is this a common issue with all AW2523HF units? I would really appreciate it if other owners could clarify this.
In my case, the noise seemed to come from the lower left corner of the monitor, and that area was visibly hot — almost uncomfortable to the touch. The unit I bought is the Rev A08 version, manufactured in September 2024, and I purchased it in January 2025. I’ve tested all available drivers and firmware, tried different outlets, and experimented with various grounding configurations, but the issue persists. Any help would be much appreciated, thank you in advance!
As for the noise, I noticed it was quite noticeable at 360 Hz, a bit quieter at 300 Hz, and it gradually decreased as I lowered the refresh rate, becoming almost inaudible around 165 Hz during regular PC use. However, it never completely went away. Interestingly, the monitor was completely silent at 60Hz. Any refresh rate above that seemed to trigger the infamous coil whine.
The sound seems to be directly related to the monitor’s refresh rate. What intrigues me is that some people can clearly hear it, while others cannot. I want to understand if those who report not having this issue simply cannot hear the frequency of the sound, or if their unit genuinely doesn’t have the coil whine.
The monitor didn’t make any sound when it was powered on. The coil whine only appeared once the Windows desktop appeared. If I power on the monitor with the PC turned off, no sound is noticeable. However, if I power on the monitor, let the Windows desktop appear (set to 360 Hz), and then turn off the PC while keeping the monitor on, the sound persists.
In the first image, the arrow points to the part of the monitor that gets very hot. In the second image, I’ve highlighted the back area of the monitor where the noise seems to come from.
Additional information: While I know that coil whine doesn’t affect the product’s longevity, the noise is so annoying that I can’t use the monitor without headphones. Additionally, I had a dead pixel in less than 24 hours of use, and Dell Brazil refused to replace or repair it. Because of this, I decided to return the product. However, I’m considering purchasing it again, as it was the only IPS monitor I’ve tested where the IPS brightness and backlight bleeding didn’t bother me.
I would greatly appreciate any information on this, as I’ve heard reports from people who didn’t experience the problem, while others have encountered the coil whine. However, I’m not sure if those who didn’t notice the noise simply cannot hear that frequency, which leads them to believe their unit doesn’t have the issue.
So, can anyone who has the same monitor or has experienced coil whine in monitors help me with this?
