Hello,
I just recently purchased an Acer W4 tablet. One of my biggest reasons for going with this instead of other competing tablets was the HDMI option. However, I cannot get HDMI to duplicate the screen onto a TV. I have tried to connect it to different TV brands and all of them show an extended screen rather than the duplicate. Since I do not have a mouse connected I cannot even use the touch screen of the tablet to use the extended screen and it's really a deal breaker for me. when I try the duplicate version but to no avail. I tried searching the threads for a solution but could not locate one. I have made all ACER and Windows updates just to make sure it wasn't a driver issue.
If there is any recommendations or ideas to help me, then it would be well appreciated.
