[QUOTE="Postal, post: 1851772, member: 404595"] So for those with a similar issue here are some observations (& assumptions) now that I have it sending the signal to an external monitor: 1. Seems the boot process needs to be quite far along before it will accept the Command F1 to send it to the external monitor - as mentioned, I didn't have a working boot disk so I guess it never reached that stage - plus the fact that I couldn't see the laptop screen to see what was happening. I think I assumed that as on a windows MOBO the signal would be output to the external monitor as soon as the laptop was turned on - like the windows BIOS info etc.. seems not to be the case. 2. To get working, I created a high Sierra USB install disk and then created a fresh copy of Sierra on an external SSD that was attached to my Macbook Pro Late 2013 machine. This SSD was then put into the 2010 machine and hey presto after 30 sec it output to the external monitor. None of the Kernel crashes I expected to see occured and it recognized all the components CPU, GPU , non retina display etc. without issue. [COLOR="#FF0000"]Next thing I would like to figure is if I can disable the Nvidia GPU and try the Intel HD graphics to see if its the GPU or the LCD - can this be done... and if it can, can it be made permanent? I don't need a dedicated GPU for what I'm doing.[/COLOR] thank you all for the input... hope the above helps someone else with a similar issue. [/QUOTE]
