When it comes to adjusting your display’s resolution, you might encounter two options: GPU scaling and display scaling. Both methods aim to resize the image to fit your monitor, but they work in different ways. Let’s break down the key differences and help you decide which scaling method is right for you. Both GPU scaling and display scaling have their merits. The ideal choice depends on your specific hardware, use case, and personal preferences. Scaling is a crucial aspect of modern computing, especially for gaming and graphic-intensive applications. But when it comes to deciding whether to perform this scaling on the GPU (Graphics Processing Unit) or the display itself, there are several factors to consider. Let’s break down the key elements of GPU scaling and display scaling, their advantages and disadvantages, and how to make the right choice based on your specific needs.

Choosing the Right Scaling Method: GPU vs. Display

Understanding GPU Scaling and Display Scaling

GPU scaling utilizes your graphics card’s processing power to adjust the resolution of the image. It offers more flexibility in terms of scaling algorithms and settings. Some GPUs even have specialized scaling technologies like NVIDIA’s DLDSR (Deep Learning Dynamic Super Resolution) or AMD’s Radeon Super Resolution (RSR). However, GPU scaling can increase GPU load and potentially impact performance, especially in demanding games or applications.

Display scaling relies on your monitor’s internal scaler to adjust the image resolution. It generally has less impact on performance compared to GPU scaling, as it doesn’t burden your graphics card. However, the quality of display scaling can vary depending on the monitor’s scaler. Some monitors may introduce artifacts or blurring when scaling, while others may have excellent scaling capabilities.

  • GPU Scaling: This method uses your graphics card’s processing power to resize the image before sending it to your monitor. It offers flexibility and often provides better image quality, especially with older or less capable monitors.
  • Display Scaling: This method relies on your monitor’s built-in scaler to resize the image. It can reduce input lag and may look better on high-end displays with advanced scalers.
