Why a normal weight result can still need review
LG publishes a 5.5 kg bare panel with 104.4 mm physical depth. The LX 45-241-224 has a depth-related capacity condition above 89 mm. This panel reaches that condition, so its nominal weight window alone cannot establish fit.
Curve radius and physical depth are different measurements
The LG sheet records 1,900R curvature. The physical depth is the front-to-back dimension without the stand, not the diagonal or the curve radius. Pivots with a stated curvature scope need their own applicability check.
Do not swap in a similar LG model’s figures
This guide is for 34GN85B-B. Do not substitute 34GP83A-B or 34GN850-B figures without verifying those exact models. A similar name or screen diagonal does not establish identical mounting geometry.
