1.MKS TFT 2.8″ connection socket graph

It is highly recommend to use external 12V/1A adapter to supply power to MKS TFT 2.8″ screen. Before plug the 12V power adapter to 2.8″ screen, please plug the “power select” jumper into DC12V position.

2)Connection

MKS TFT2.8″ use a special  8 pin parallel cable to connect the board to ramps1.4  main board. This cable is different from traditional 8 pin parallel cable which is often used to connect DVD and hard driver. We highly recommend you to use the Osoyoo factory 8 pin cable which comes with the 2.8 inch screen.

Sometimes your screen might not display anything. This is because you have used a traditional 8 pin cable, you need turn cable head 180 degrees and then push it by force  into the “mainboard interface” socket, then the screen will work.
