Oh I see, okay that's a key piece of info, thank you.

I am not aversed to research but Heads is seeming enigmatic, do you have 
any suggestions for guides etc. any advice you could give me would be much 
appreciated.

Will I have to add my FHD 1080p screen to the build?

Thanks,

Stacey

Hi Sven,

That's great info, thank you!

Other than these issues mentioned above, your fhd mod worked smoothly? As 
in, no need to add change anything during the heads build process?

I will certainly let you know how it went although, I will probably be back 
asking more stupid questions in the future before it's finished lol

Thanks,
Stacey
