This is a good computer. I had the HDMI port stop working with the TV after about 5 months. After trying several different things (checking to make sure the ports worked with other devices (which all worked), changing the HDMI cables, reinstalling windows, unscrewing the bottom and taking out the battery to restart bios, changing settings in bios...), I determined that it was the transfer rate of the HDMI port (I'd guess it was transferring as if it were a HDMI 1.4 vs the 2.0 port). The computer would work with computer monitors and a few TV's, but not the ones I wanted to use it on. Corresponding back and forth with Kingdel in China via email, they tried suggesting several things and very quick in response.  After trying many different ideas (using an HDMI switch, HDMI booster...), I found that an HDMI to VGA adapter with a micro usb power cable was exactly what I needed. It gives me the same good quality on the TV screen as when I used it the previous five months.
