iiyama G-MASTER GB3461WQSU-B1 fault?

[Tony123]

Hi I have the
iiyama G-MASTER GB3461WQSU-B1 computer monitor 34" 3440 x 1440 UWQHD.

yesterday all of a sudden the screen went black, tried turning off and back on, the white logo screen came on and off but no picture, I tried pressing the settings button, but the option menu flashed on screen for 1/2 a second. There is power to it. I tried another screen incase it was my pc, but its working fine.
I also removed the power lead and refitted incase it was loose, but that was fine. Has any one else had this or know a quick fix? I only had it since Jan and bought brand new. Thanks for any help

Thanks for link, no its.not my settings it broke during a game. I removed the monitor cable and left it for a day, turned it back on not connected, the screen is still dead apart from the initial start up logo. And settings ui pops up for less than 1/2 a second
