I'm not sure what happened I ordered it came to me damaged from the delivery driver like they must have been throwing it around in the truck it was an easy exchange but I feel like I got the same product that was previously damaged no signal for the monitor that I connected bought a HD monitor no signal for that it comes on but I can't see anything of course so I'm just not going to bother I suggest that nobody buy this cuz they don't do a good job in caring for their package so I have a tower that turns on but can't hook up to a monitor
