Why is the image captured by `SCScreenshotManager.captureImage` so blurry?

I am using ScreenCaptureKit to create a screenshot software, but I found that the screenshot captured by the new API, SCScreenshotManager.captureImage, is very blurry.

This is my screenshot. It is so blurry.

But I hope it's like this.

My code is as follows.

func captureScreen(windows: [SCWindow], display: SCDisplay) async throws -> CGImage? {
    let availableWindows = windows.filter { window in
        Bundle.main.bundleIdentifier != window.owningApplication?.bundleIdentifier
    }

    let filter = SCContentFilter(display: display, including: availableWindows)

    if #available(macOS 14.0, *) {
        let image = try? await SCScreenshotManager.captureImage(
                contentFilter: filter,
                configuration: SCStreamConfiguration.defaultConfig(
                        width: display.width,
                        height: display.height
                )
        )
        return image
    } else {
        return nil
    }
}
extension SCStreamConfiguration {
    static func defaultConfig(width: Int, height: Int) -> SCStreamConfiguration {
        let config = SCStreamConfiguration()
        config.width = width
        config.height = height
        config.showsCursor = false
        if #available(macOS 14.0, *) {
            config.captureResolution = .best
        }
        return config
    }
}

Note that SCDisplay’s width and height properties are specified in points, while SCStreamConfiguration may expect width and height to be specified in pixels.
