→AI-powered filters
;Before diving in;
;*Some of the shaders and filters listed below are already included in the chain for some of the [[Shader Presets]] or present as an enhancement/adjustment option (such as [https://www.nvidia.com/content/Control-Panel-Help/vLatest/en-us/mergedProjects/nvdsp/To_use_Digital_Vibrance_to_make_your_desktop_colors_richer.htm digital vibrance]) from [https://www.pcgamingwiki.com/wiki/Category:Graphics_Adaptor GPU driver control panel] or from your digital [[displays|display]] OSD. Some of those things may cause color clipping, over-exposure issues (due to using excessive digital adjustments to image) and [[Input lag]]. It's recommended to avoid usage of color or excessive image options/filters. You But you can use HDR devices (if it[[Displays|analog device/CRT]]'s possibleOSD adjustments. Another proper option for this using the RTX Dynamic Vibrance option (see [[#AI-powered filters]]) to avoid color crashing and top of that using a HDR device with [[High_dynamic_range#Inverse_tone_mapping|Inverse tone mapping]].
==Types==
You can combine those things with these two shader presets: [https://github.com/libretro/common-shaders/blob/master/cgp/tvout/tvout.cgp tvout.cgp] for 240p and [https://github.com/libretro/common-shaders/blob/master/cgp/tvout%2Binterlacing/tvout%2Binterlacing.cgp tvout+interlacing.cgp] for 480p. Both of these allow you to have adjustable signal resolution blur applied horizontally, as well as color controls like gamma, saturation, and the option to use TV color range (16-235) instead of PC color range (0-255), while the 480p version provides a scanline shader that is interlaced on 480-line content. The signal resolution blur works best if you use a large horizontal resolution (1280 or higher recommended) while keeping your vertical resolution at 240 or 480, and setting the aspect ratio of the emulator to stretch to fit. The higher horizontal resolution will make it look natural and convincing, avoiding banding issues. Can be combined with NTSC filters/shaders for maximum authenticity, check out the shader presets in [https://github.com/libretro/common-shaders/tree/master/cgp/tvout /cgp/tvout] and [https://github.com/libretro/common-shaders/tree/master/cgp/tvout%2Binterlacing /cgp/tvout+interlacing] for some examples.

AI-powered filters are a new technology with the potential to further improve the emulation experience. These filters use machine learning to automatically enhance the visuals of content. Nvidia recently release their new Nvidia App[https://www.nvidia.com/en-us/software/nvidia-app/] which comes with new AI-powered filters called "Nvidia FreeStyle", one of the filters is RTX Dynamic Vibrance which is an AI-powered dynamic image enhancement without crashing colors. AI-powered filters offer exciting possibilities for the future of emulation. As the technology matures, expect even more advanced features and use cases to emerge, further improving the way we experience various content such as classic video games.
