+The effect combines several classic CRT artifacts that you can dial in independently: scanlines (**Line width** and **Line contrast**), screen **Curvature**, static **Noise**, and a darkened **Vignetting** around the edges. Set **Interlaced Lines Speed** to make the scanlines scroll, and **Noise Frequency** to control how often the static is refreshed (0 keeps a fixed noise pattern). Enable **Show vertical lines** to add vertical lines on top of the horizontal ones.

Instead, it's starting from the original output and displays the screen differently based on the displacement map. For example, if a displacement map pixel has red = 1 and the filter scale is 20, this filter will output the pixel approximately 20 pixels to the right of the original.
 
+The **Scale on X axis** and **Scale on Y axis** properties set how strong the displacement is on each axis. Larger values produce a more pronounced warp, and you can set them independently to distort more in one direction than the other.

 This is a faster version of the traditional "Blur" effect. It's recommended that you use this one rather than the "Gaussian" blur effect.
 
+The **Blur** value sets the overall strength of the blur. **Pixelize X** and **Pixelize Y** let you stretch the blur along one axis only — for example, a horizontal or vertical motion blur. Increasing the **Quality** produces a smoother result at the cost of performance, so keep it low unless you need a very strong, clean blur.
