Flickering monitor - random

MrChris37

I recently (within the last 3 months), purchased two LG 24" monitors back on 2/27. One of the two monitors randomly flickers off and on and is very unstable. I've done all the troubleshooting I could think to do.  Different power strips, different display cables, different graphics cards and different computers altogether.  I even reset the monitor to defaults to no avail.  The monitor will still black out and come back on then black out again. Doesn't matter if it's during POST or when the OS is fully loaded. I don't have the original packaging or box because it had been working fine for a while.  Is it possible to get an even exchange for another monitor, or something like that? I have the original receipt.
