是否可以全屏显示整个屏幕？当我使用全屏选项显示我从 Beamer 演示文稿创建的 PDF 文件时，我发现屏幕的右侧和左侧浪费了一些空间。但我们知道全屏模式下的 PowerPoint 会覆盖整个屏幕而不会留下任何黑色空间...任何帮助都将不胜感激。

\begin{frame}{Introduction}
Random sampling is done to gather data about the population in order to make an inference that can be generalized to the population.\\
\vspace{12pt}
Steps in sampling
\begin{itemize}
\item Define population $(N)$ to be sampled
\item Determine sample size $(n)$
\item Control for bias and error
\item Select sample
\end{itemize}
\end{frame}
% FRAME 2
\begin{frame}{Introduction}
\textbf{Define population to be sampled}: - Identify the group of interest and its characteristics to which the findings of the study will be generalized.\\
\vspace{12pt}
\textbf{Determine sample size $(n)$}:- The size of the sample influences both the representativeness of the sample and the statistical analysis of the data.\\
\vspace{12pt}
\textbf{Control for bias and error}: - Be aware of the sources of sampling bias and identify how to avoid it and decide whether the bias is so severe that the results of the study will be seriously affected.\\
\vspace{12pt}
\textbf{Select sample}:- A process by which the researcher attempts to ensure that the sample is representative of the population from which it is to be selected.

可能是宽高比投影机的屏幕比例与演示不匹配？您可以尝试使用 更改为 16:9 \documentclass[aspectratio=169]{beamer}。正确的比例取决于您的投影机。顺便说一句，请尝试使用平均能量损失。
