ACER XG270HU started Blinking....still having the same issue.

Sadeem · January 2023

So I have 2 27" XG270HU, they both worked great without issue and 144h.

Oneday I turned them off, went to bed, woke up, turned them on and one of them started to blink.

I thought it was the cable HDMI and DP, I changed both that and didn't work.

I thought It was the monitor powersuplly, I switched it with the one that works and still having the same issue.

I removed all the cables from both and just turned them on, one of them starts blinking the other works fine.

I did not install any new driver to the OS or Firmware to the monitors.

Note: the Power does not go away, it keeps showing a blue light as it's working normally, it just the LCD

Since I can not attach a video, I uploaded to this link

Turn off the monitor and unplug all the wires goes to the monitor. Than press and hold the power button on the monitor for 30 seconds.

Than connect the cables and check . May i know to which device you have connected the monitors?

I tried this method too, it didn't work.

I tested it again with 1 Min, still have the same issue.

Seems like an electrical issue or something that overheats maybe (IDK)

I have 2 monitors connected to a laptop via HDMI.

1 directly connected to the laptop, the other is via USB-C hub that has HDMI output.

I've been using this configuration since COVID hit.

Were you ever able to figure out a fix or is the monitor just toast?

Mine started doing the same thing today. I also have two of the same monitors and it is just one of them doing it.

replace the HDMI cable or maybe the monitor becomes defective
