Purchased this due to the 4 hdmi inputs on a 2015 Sony Bravia tv no longer working and save expense of repairing or purchasing a replacement TV.
Simple to set up but no connecting cables are supplied to make sure you have them already. Other than the conversion box itself, the only other item included is an AC/DC adaptor to power the box. The one I received didn’t work but I was able to use a plug I already had to power the unit. Simple setup when using to connect a MacBook to TV. Obviously the picture quality is not as good as direct HDMI connection but cheaper than replacing the TV and good enough for the odd time I need to display the computer on a larger screen.
