When I hooked up this computer, there was no video output. Monitor is working flawlessly with my other computers. Had to wait a week for a defective product. Do not buy from this seller.  Now I' going to have to wait for a week for my refund andif I decide to order another it will take another week to get here, so maybe in 2-3 weeks I will be able to acquire a useable machine. A totally unsatisfactory experience all the way around.
