lg on screen control not detecting monitor

A 4K monitor larger than 27 is not quite retina quality by my calculations. My main goal was pixel density and readability benefits similar to the screen on my Surface Pro 4 and the Retina display on my iPhone. Whew! And I thought I’d have to spend money and change ports or worse, have the board replaced (that’s expensive!).

Question: Q: Macbook Air display not recognized on LG monitor Just got a new LG monitor as a second screen for my Macbook Air (Late 2015), but I cannot for the life of me get the connection to work. I thought the port was the problem because when I plugged my HDMI cable to the other HDMI ports 2, 3 and 4, video and audio worked well and when I reverted back to the HDMI port 1, audio would be absent.

These days HDMI and Display ports are much more popular than VGA and DVI because VGA and DVI are old standards. Video was fine but sound was non existent.

The cable box on my 75”LG on HDMI port 1 lost sound all of a sudden.
