Hi all, i just got a x2401 HP monitor recently and found a some problems with it. It is intermittently flashing on and off and sometimes the screen will be black all of the sudden for no reason. I am using hdmi to hdmi port for it. Is it something wrong with the monitor? Anyway to test it out on my own without bring it back to the shop? Any help or advice is highly appreciated. Thanks in advance

try use your onboard graphic( if have )
if dont have use another pc/laptop to test

Tested it on my laptop and tv, all same error. send back to the shop..turns out the hdmi cable is faulty..changed a new one and alll is good. Thanks for the helpful suggestion c:
