So I have a 52" LCD HDTV from 2011 here is the model number:
It's having problems connecting up with our new Lenovo workstation laptops. It will work for plugging in the first time with a laptop but after that I have to unplug and plug back in the HDMI cord on the back of the TV (which is a pain to get to). I'm thinking that it is a software upgrade issue simply because we've never done it. What software should I load on a USB to update it with?
