We consider the nonparametric Euler–Lagrange equation which arises from an elliptic parametric functional with integrand F depending on normal directions only. We show that every entire solution must be an affine linear function, if F is C3-close to the area integrand and |Du(x)|=O(|(x,u(x))|γ), γ∈(0,1).
