I’ve seen people using a 2011 screen on the 2012 model but is it possible to do it the other way round? My 2011 screen died on me and I have a broken 2012 lying around.
As long as they are both Unibody systems! You can’t use a Retina display on a Unibody. Be aware the 2012 systems use a slightly different LVDS connector! Most people are placing the 2011 15” hi-res matte or gloss displays onto their 2012 system. Here the LVDS cable tang needs to be ground down a bit, so it can fit. If done correctly there is no issues. Here you’re doing the reverse! The 2012 display LVDS cable is a bit smaller so make sure you’ve centered the cable in the connector otherwise you risk shorting out! Frankly, I don’t think its wise as you could damage your logic board and the display! The 2011 & 2012 displays are no different otherwise!
Should be all good might be bit hard to connect it.
