HDMI connected on Google Nextbook 8 when no HDMI connected Recently, my Nextbook 8 has been acting oddly. What it does is switches into HDMI mode, though there is no HDMI cable plugged in.

I first noticed this on Sunday. The screen was refusing to rotate, even for apps that required a different screen orientation. When I figured out that HDMI Switch was on, I turned it off and that fixed the problem. Temporarily.

Now, the screen flashes frequently as it "connects" and "disconnects" from HDMI, which makes using it next to impossible. Sound stutters when it does this, and if it's "connected," I can't watch videos on it.

I've never once connected HDMI to it, and I take care of my electronics. I've never dropped it, I have anti-virus on it that finds nothing wrong, and I haven't downloaded any new apps. I've found nothing online to help me solve what could be causing this, though I've been searching since Monday. All problems I've found through searching have been "HDMI not connecting" issues instead.

Any help would be greatly appreciated in this matter.
I actually had this very same issue. 

I contacted Nextbook and it was very hard to get in touch with them by phone or email. Finally I got an email back with some ideas, including doing a reset for the whole tablet. 

However, I believe what actually fixed it is that I bought a cheap HDMI to mini-HDMI cable on Amazon to plug into my TV (which works quite nicely) and once I plugged it in and out, that seemed to fix the problem of sound not working/screen rotating. I haven't seen the problem happen again, so I think there was just some slight connection problem that is now okay. I hope it works for you.
