I bought it in February. I'm using the HDMI input on the monitor. No problems for six months. Then I got no video. Tried a different monitor and a different cable, both of which work fine on my Windows PC. Took it to the store where I bought it, hooked it up to a new monitor and it was fine. Bought the new monitor. After a week, same thing; no video. Hooked my Chromebook to the monitor, no problem. Mac Mini- no video.
