Windows 7: Monitor flickers

Monitor flickers

I've got this monitor -- LG 29UM65 Black 29" 5ms Dual HDMI UltraWide screen LED Backlight LCD Monitor IPS Panel 300 cd/m2 5000000:1 Built-in Speakers - Newegg.com

All of a sudden, my screen flickers and goes nuts.

I have to shut down the comp and reboot.

I heard a crackle the last time it happened coming from the monitor.

It's only a month old.

Bad monitor or something else?

Could the PSU be failing?

Thanks,

Paul

If you mean the Power Supply built into the monitor, that could possibly be it. The computer's PSU has nothing to do with the monitor itself. I've had monitors do what you describe and it was the monitor power brick (or internal power) which was usually the culprit. Being brand new, I'd look into an exchange. Before doing that I would hook it up to another computer. If it does the same thing you will be sure it's something to do with the monitor.

Thanks for reply,

It's been all right for the last hour or so
Maybe just a hiccup?

I'll connect it to my laptop and let it run for a while.

If it happens again, I'll have to return it.
