I have tried the Terminal command: ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6 And I get no return line. It just takes me to the prompt again. In the color Profile I have Manufacture listed as 00000610 and the Model 0000A014. Neither give me any info in Google. I have never noticed any burn-in so I assume I have a Samsung.
