Try using a few different video cables before returning. By default, some will use a VGA or DVI cable to initiate the start up. Most monitors should just be HDMI ready and go, but I would check first to see if it's not just a simple legacy error.
Sorry I kinda messed up the format, my monitor responds to my computer and turns on but then it has just a black screen, not even backlit, and then a couple seconds later it turns off.
Is it a brand new monitor? Do you mean it powers on, but then goes to standby w/ light orange or blinking? You might want to try a "factory reset" in the monitor OSD. If that doesn't work, I'd try another output on your GPU, such as DisplayPort, HDMI, or DVI-D. Is this your only monitor? Also, you system specs may help to find an answer.
Yea I bought it a month ago and it was working last night. This monitor just has a light but it turns on like it normally does but the screen just does nothing. I tried another monitor and it works fine, and I tried a bunch of different ports too, I'm almost certain it's just a monitor problem because my computer detects it as a monitor if I plug it in. It's the lg 27ud68-w and I'm running a i7-4790k and a Msi gtx 960
No UEFI/BIOS screen either? Does it come up then go out when Windows itself is loading? If you get nothing, it does sound like the monitor since the other monitor works fine. Factory reset within monitor not work either?

Hello i know this is an old replly but i just bought this same monitor and after switching from the Display port connnecting to a "Better" DP this same thing happend.
The solution was to unplug every single cable/USB/Connection from my computer, let it rest for a minute then woala, the screen worked.
