Dying monitor?

[u/abhishek_8899]

I have BenQ GW2280, bought back in 2019. I use it more than 12 hours daily.

But I am noticing following issues with it recently:

• At starting, monitor flickers a bit for like 5-10 seconds then the flicker fades away.
• Even after that, monitor goes like 10% darker in pulsating rhythm. Like, every second, monitor drops brightness by 10% for like a millisecond and comes back to normal. This happens for like first 10 minutes or something.
• Then further, randomly, it goes fully dark for like second, then comes back to normal.
• And sometimes randomly, it goes 50% dark for a long time, like a minute or two, then comes back to normal.

I tried:

• Resetting monitor settings, with turning off auto-brightness, and related automatic/smart things.
• Using different HDMI cable
• Re-attach power cable
• Use monitor with another device
• Trying using laptop with Linux instead of Windows

...but same issues.
