hi

just purchased a used ThinkCentre M92P-Tiny and trying to connect to a TV with DP TO HDMI lead 

the machine detects the tv but i get no signal, for the past 2 days i have scoured the internet looking for soloutions and tried everthing but still getting nowhere, all drivers and updates are up to date, the bios is the latest etc  

i am starting to think it is the machine that is faulty or the lead !

before i buy a new lead or even send the machine back i was just wondering if there is something else i am overlooking

any feedback would be appriciated 

thanks
