Question:

“I’m experiencing an issue with my Surface Pro 4’s miniDisplayPort to HDMI connection. I’m using [this specific adapter](https://www.amazon.com.au/dp/B00S0BWR2K?ref=ppx_yo2ov_dt_b_product_details&th=1), and while the second display is recognized in both Windows settings and the Intel Graphics Command Center, I’m unable to extend or duplicate the display. It defaults to ‘show only on 1’ and reverts back to this setting after attempting to change it. Additionally, enabling the second monitor in the Intel Graphics Command Center has no effect. The device manager does recognize a second generic monitor and even identifies the LG brand. What could be causing this issue and how can it be resolved?”
