Nice setup (that i'm looking to copy). I also have an NC750 screen but it doesn't look exactly like the one in your photos. My NC750X 2018 screen is W380mm, H380mm, t=5mm and, whilst the top of the screen is flat (ie horizontal) the screen is curved in x-section, ie put a straight edge across the back of the screen (near the flat top edge) and the gap between the straight edge and the centre line of the screen measureas ~25mm. So any comments pls on whether or not the Universal screen extender would fit before i order one using your link?? Hope above makes sense! Thks.......
