Always use 3440x1440p to avoid pixelation on ultra-wide screens.

Modern implementations often use GPU-accelerated shaders (via software like Wallpaper Engine) to render the effect in real-time. This allows for interactive elements, such as the code reacting to mouse movements, without taxing the CPU.

Moving beyond simple neon green to include "phosphor glow" and trailing gradients that mimic old CRT monitors.

To achieve an "excellent" rating on an ultra-wide monitor, a screensaver must address three primary technical hurdles:
