Bought the following brand new at Best Buy on 8/22/14, and trying to get setup: Lenovo K450e desktop tower, keyboard, and mouse. LG 22MP56HQ monitor MS Office 2013 (key code) Webroot internet security (disc) After connecting everything according to the instruction of both the Lenovo and LG instructions, double & triple checking all parts accounted for and connected properly, here's what happened.. Lenovo tower boots up fine, disc drive in tower opens and closes properly, Lenovo keyboard and mouse both detected. Great so far except... LG monitor does not turn on at all. In the back of the monitor, two things are connected: blue HDMI connector with pins on both sides is connected to HDMI connection in back of tower. AC DC adapter plugged into electrical outlet and other end directly into monitor. Everything works when power booted up except monitor shows no life - no light indicator, and black screen. Monitor just doesn't turn on at all. There are driver discs for both lenovo win 8.1 and the LG monitor, and like I said, I can insert them into the tower and close, but nothing happens on the monitor display. Best Buy said it should be no issue using the LG monitor with the Lenovo PC tower. They will charge me $100 to come out to my home, even though I bought two year Geek Squad plan, They also said I would still get charged even if they were unable to get me setup. Seems like there is one probably really easy fix, but I don't want to pay $100 to have them come out if I get charged regardless of the outcome. Anyone out there with any idea what could be preventing the monitor from powering up (other than it's bad, which is unlikely, as it was brand new, sealed in the box)?? Thanks.
