I first got this working about a month ago and noticed on here almost everyone with Intel graphics still hasn’t got it working. I recorded a video to show you how I did it. Not mentioned in the video but I am running the latest BETA drivers for Intel Graphics from Intel’s website. Older graphics wouldn’t let me change the timings which is essential to get to work.
Please reply here if this works for you as I am interested to see if it works the same way for other graphics adapter, TV and HDMI cable combinations.
