Where 8.4" Fits
Across the LH Series Open Frame Monitor range, 8.4" is the 3rd smallest of the 8 published sizes in this family, sitting between 7" and 10.4".
The 170.4 × 127.8 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; 800×600 renders natively with no scaling. Against the 7" next to it in this family, the active area is 16.2 mm wider and 41.9 mm taller.
