Changing screen resolution

Overview

To improve compatibility, operating systems with a graphical user interface (GUI) use a low default screen resolution. If the default resolution does not meet your business requirements, you can change it as needed.

Scenarios

Model training/data science

You need to view multiple windows side by side, such as TensorBoard, W&B, Jupyter Notebook, and system resource monitoring tools (for example, nvidia-smi), to track training status in a timely manner.

You need to clearly view complex charts, feature maps, and 3D rendering results to analyze training performance.

Video editing/graphics rendering

You need sufficient layout space for the timeline, effect controls, media library, and preview window in video editing software to prevent panel overlap.

You need to preview video clips at a resolution close to the target output (for example, 1080p) so that you can check video details.

Remote desktop and debugging

Set the remote desktop screen resolution to the same as that of the local display so that you can perform full-screen operations seamlessly and reduce scrolling.

Prevent graphical development tools (such as IDEs) and database management tools from having broken layouts caused by undersized windows.
