 ## Description
 
-The `setKmsCanvas` method configures a kernel-mode setting (KMS) canvas, enabling the CheerpX Linux instance to render graphical. The dimensions of the canvas are defined by the `width` and `height` parameters, allowing the application to adapt to different display sizes dynamically.
+The `setKmsCanvas` method configures a kernel-mode setting (KMS) canvas, enabling the CheerpX Linux instance to render graphical output, for example via Xorg. The dimensions of the canvas are defined by the `width` and `height` parameters, allowing the application to adapt to different display sizes dynamically.
 
 ## Example
 
 ```ts
 function setScreenSize(display) {
-	// Determine scaling factor
-	let scaleFactor = 1.0;
 	const displayWidth = display.offsetWidth;
 	const displayHeight = display.offsetHeight;
 
-	// Minimum width and height for the canvas
-	const minWidth = 1024;
-	const minHeight = 768;
-
-	// Adjust scale factor if the display is smaller than the minimum
-	if (displayWidth < minWidth) {
-		scaleFactor = minWidth / displayWidth;
-	}
-	if (displayHeight < minHeight) {
-		scaleFactor = Math.max(scaleFactor, minHeight / displayHeight);
-	}
-
-	cx.setKmsCanvas(
-		display,
-		displayWidth * scaleFactor,
-		displayHeight * scaleFactor
-	);
+	cx.setKmsCanvas(display, displayWidth, displayHeight);
 }
