# 更改 UEFI 虚拟机的分辨率
通过修改 OVMF 平台配置的显示设置来更改基于 UEFI 的虚拟机屏幕分辨率的步骤。
在基于 UEFI 的虚拟机（VM）中，屏幕分辨率由 OVMF（Open Virtual Machine Firmware）平台配置控制。默认情况下，VM 只能使用平台设置中配置的分辨率。如果您需要更改显示分辨率，请按照以下步骤操作。
## 更改屏幕分辨率的步骤
1. **重启 VM** 并保持连接到控制台（通过 VergeOS UI 或您正在使用的任何控制台管理器）。
2. 当 VM 启动时， **按** ESC 进入 UEFI 设置菜单。
3. 进入 UEFI 菜单后，导航到 **设备管理器**.
4. 在设备管理器中，选择 **OVMF 平台配置**.
5. 选择您所需的 **首选分辨率** 从可用选项列表中。
6. **保存** 配置更改，并重启 VM，使新分辨率生效。
## 注意事项
* 可用的分辨率选项取决于固件和来宾操作系统的显示能力。
* 如果您仍然遇到分辨率问题，请确保您的来宾操作系统已安装必要的显示驱动程序。
* UEFI 设置可能会因 VM 和配置而略有不同，因此在某些环境中，部分步骤看起来可能会有些差异。
按照这些步骤，您可以成功调整基于 UEFI 的 VM 的屏幕分辨率。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.verge.io/knowledge-base/zh/virtual-machines/changing-resolution-on-a-uefi-vm.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
