Greetings to the community of Techspot i am here to ask you for a solution to my problem. (To be honest i dont even know if this is the right thread for my post but i couldnt find a categorie which fit better to it! So let me get to the point. The whole deal is about a wierd message that is appearing to the screen after i shut down my computer and this message is no other than "Check signal cable" Before u propose me anything let me tell/ask you 1-2 things 1:This is not the monitor''s malfuction ( tested it with another monitor)(dont know about the graphic's card thought) 2:Lets say i cant find how to repair the problem is this something that can be harmfull for my monitor? 3:If yes why ? So pretty much thats it! Thanks in advance.
