Where 12.1" Fits
Across the LH Series Open Frame Monitor range, 12.1" is the 5th smallest of the 8 published sizes in this family, sitting between 10.4" and 15".
The 245.76 × 184.32 mm active area is close to a 1.3:1 aspect, near-square enough for legacy 5:4 or 4:3 software layouts — both dimensions matter here, so check the outline against your enclosure; 1024×768 renders natively with no scaling. Against the 10.4" next to it in this family, the active area is 34.6 mm wider and 25.9 mm taller.
