Turn ANY Mac into a SECOND MONITOR! (No Target Display Mode Needed!)

This video will show you how to use any Mac or PC desktop or laptop as a second monitor for another computer. These methods are DIY alternatives to commercial options like Luna Display or Duet Display.

Please note these specific items below have not been personally tested, but are suggested based on knowledge and experience. I tried select reputable products, but if you've done your research feel free to opt for cheaper options. Please read over each before purchasing, as sellers do sometimes change the products behind a product page.

-- USB HDMI Capture --
"El-Cheapo" 4K* - https://amzn.to/3FLw7kJ
UGREEN 4K (more reputable!) - https://amzn.to/4c6wBOg

*The USB capture shown in the video is similar to this one I call "El-Cheapo", but not the exact same one or seller I bought. It had drivers baked into Windows and Mac (or pulled from Windows Update?); I would NOT recommend installing any CD that is included! Although they look identical, they are made by many sellers in China and not necessarily the same. Some people don't feel comfortable plugging in no-name USB devices made in China into their computers, which I understand, which is why I also included the suggested UGREEN which would be considered more reputable. The UGREEN is also USB 3.0, and likely is also using better processors for much better performance and lower latency. If you happen to use the UGREEN, please comment below how it compares to the "El-Cheapo" one that I used as far as latency.
