Which video card specification has the greatest impact on display quality for a video editor?

The specification that has the greatest impact on display quality for a video editor is the refresh rate. A higher refresh rate can lead to smoother motion and reduces the likelihood of motion blur, which is crucial when editing video content. Video editing often involves reviewing footage frame-by-frame, and a higher refresh rate allows for a more fluid experience on the screen. This is particularly important for capturing fast-moving action or making precise edits without visual artifacts.

While memory size, GPU speed, and the number of outputs all play significant roles in the overall performance of a video editing setup, they do not directly influence the quality of the display itself in the same way that refresh rate does. Memory size is important for handling larger projects and high-resolution footage, GPU speed affects rendering times and real-time previews, and the number of outputs pertains to the capability to connect multiple displays or projectors. These factors contribute to the editing process, but the refresh rate more directly influences the visual experience during editing.
