I love Onda V820w HDMI output as I can use it as set-top box or game console. You can setup HDMI output on Windows 10 just like other normal monitor. And plug and play on Android. There is an advanced HDMI features on Android actually but hidden away. You get to select HDMI resolutions, scaling and overscan compensation once enabled. Note – root access is required though. By the way, is your Onda V820w HDMI working? If no, do refer to this guide to fix it – How to fix Onda Tablet HDMI port not working? No need to send back for warranty claim.

Err… Onda V820w dual OS tablet’s font is a little bit small for both Windows and Android. Not an issue on Windows as fonts are clear and sharp thanks to ClearType feature. However, it’s kinda blur on Android. Is there a way to fix it? Yes, but root access is required in order to change it. We need to increase its LCD density from 160 to 210 dpi (which I prefer). You can always change to any value that suit you. Basically, this method works on every Android device. By changing LCD density, you can change the UI layout from phone to tablet. Or the other way around. Just don’t go over 220 dpi on Onda V820w else you will get phone layout then. By the way, the optimum dpi for Onda V820w is 188 dpi. But I prefer a bigger one…

Help! My Onda Tablet micro HDMI output port is not working. Yes, my Onda V820w is having this issue. Not sure other Onda Tablet like V919, V989, V891, V116w, oBook 10 and 11 are facing this kind of problem or not. Anyway, here is a solution for this problem. And it is working perfect on my Onda V820w Dual OS Tablet. And it should work for yours too. Basically, Onda tablets have deeper micro (not sure about mini version) HDMI port which requires same length as male micro USB head. Therefore, generic micro HDMI cable will not work as the male HDMI head is not long enough to get proper connection. Luckily, the fix is very simple. Get yourself a new HDMI cable that match your Onda tablet. Or modify yourself by following below guide…
