SCREEN DISPLAY ONLY SHOWS 2/3RD OF SCREEN
Hi all, I added SDD in my iMAC iMac (27-inch, Late 2013) to convert it into fusion drive. All was done with extra care. Connecting display screen back , I can only get 2/3rd screen working with no obvious issue and right 1/3rd remains dark and not showing any signs or display. Could anyone help ,please.
Thank you
