I hope this is being posted in the correct forum. I have been having a hard time getting my tablet to cooperate with a 2nd display via HDMI.
I have an UnBranded brand Windows 10 tablet. It has a micro-HDMI port. I have tried to mirror the screen to a TV or computer monitor using HDMI cord, and I have learned that this seems to be impossible. There are a few display options that are available. One of these options makes the picture on the monitor a very small duplicate of the image on the tablet, and it will not go fullscreen. Another option allows me to extend the desktop, which puts a blank desktop wallpaper on the 2nd monitor and I cannot get the monitor to show any of the activity that is actually happening on the tablet. The 3rd option I have will broadcast the tablet very well in full screen on the 2nd monitor, but it will turn off the tablet screen. The tablet obviously is controlled by touching the screen and so this option makes it impossible to control when the tablet screen is off.
Then I attempted to use a Bluetooth keyboard with a BT dongle plugged into the tablet. This worked great for controlling the tablet on the 2nd monitor while the screen is off. However, when I tried to play streaming video that normally plays very well on the tablet, the video moves in slow motion on the 2nd display, and there is no audio.
Is there something that I am doing wrong in this process? If not, what is the point of everyone wanting tablets that have HDMI if the hardware is unable to scale the video to a 2nd larger display?
Thank you in advance for any guidance you can give.
