mwg Posted September 18, 2013 Share Posted September 18, 2013 Hi, i need to be clear on something Are all dmd sizes the same? What i really need to know are they all the same aspect ratio? The Vishay DMD has Viewing Area: 12.75" [323.8 mm] (W) x 3.15" [80.01 mm] (H) Because this is such a popular dmd i use this as a guide. i have a 9 inch 16:9 ratio lcd for a small cabinet. It has a Active area 198.000(W) mm × 111.696(H) mm so to make a hole with the correct dmd ratio i need to make one 198mm (W) x 50mm (H) right?

mameman Posted September 18, 2013 Share Posted September 18, 2013 Std DMd hole size is 13.5x3.5 with 1/4" rounded corners WWW.Xtremepinball.com Link to comment Share on other sites More sharing options...
mwg Posted September 20, 2013 Author Share Posted September 20, 2013 Thats what i meant, Vishay DMD has Viewing Area: 12.75" [323.8 mm] (W) x 3.15" [80.01 mm] DMd hole size is 13.5x3.5 so my 9 inch 16:9 lcd is only 198mm wide (7.8 inch) then my height must be 2 inch? for the correct ratio?

Lamprey Posted September 28, 2013 Share Posted September 28, 2013 I might be doing my math wrong, but I come out with 7.8" wide x 1.3" high to keep the same ratio (12.75" x 3.15") Link to comment Share on other sites More sharing options...
