  • By reformulating your equation or buying a 16:9 projector. – percusse Nov 9 '14 at 22:43

You can use the option aspectratio=169 as percusse says in \documentclass[aspectratio=169]{beamer} to get

Or use the symbol for Laplacian

\begin{align}
\frac{-\hbar²}{2m}∇^{2}ψ(x,y,z)+V(x,y,z)ψ(x,y,z) =     Eψ(x,y,z)\label{ecu-gen}
\end{align}

to get

Or try to split the equation into two lines using amsmath (split/align/multline)

\begin{multline}
\frac{-\hbar²}{2m}\bigg( \frac{∂²}{∂ x²}+\frac{∂²}{∂ y²}+\frac{∂²}             {∂ z²}\bigg)ψ(x,y,z)+V(x,y,z)ψ(x,y,z) \\
=     Eψ(x,y,z)\label{ecu-gen}
\end{multline}

Another solution with the aligned environment and the \mathllap command from mathtools:

\documentclass{beamer}

\hypersetup{pdfpagemode=FullScreen}
\usefonttheme[onlymath]{serif}
%\usefonttheme{professionalfonts}% font de LaTeX
\usetheme{Berlin}
%\usecolortheme{miniframes}

%\usepackage{listings}
\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{amsmath,amssymb}
\usepackage{mathtools}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{tikz}
\usepackage{nccmath}

    & = E\psi(x,y,z)
\end{aligned}
\end{equation}
