Meant to be Seen

I realise the screen on the DK2 is just taken from a Galaxy Note 3, but I can't seem to find the actual physical dimensions of the screen anywhere (I am sure I am just not looking in the right place). Does anybody know it in mm?

Please don't just convert 5.7 inches to millimeters, I can do that myself, it's the X and Y physical dimensions I am curious about.

Thank-you!

From http://pdadb.net/index.php?m=specs&id=5 ... e_3_td-lte :
- 2.79 " x 4.95 " (70.74 x 125.77 millimetres)

I did find other references with the same values in the Android GPU implementation IIRC but I can't find them anymore.

Thanks Fredz

Just a note for future reference in case you only find one dimensions listed, there are 3 measurements for screen dimensions.

Like here is the Sharp 5.9"

Active Area : 72.9×129.6 mm (W×H)
Bezel Area : 73.9×130.6 mm (W×H)
Outline : 76.2×139.1×1.65 mm (W×H×D)

If you only find one listed measurement, it may not be the one you need. Like if the display you want is part of an assembly it may be listed as much larger than the display panel itself.

In this specific case the values are given for the viewable display size though, but thanks for the precision.

If you know x and y resolutions hence aspect ratio you can do calcs
