I always see a kind of noise in the screenshots you post.
Just curious, is it intended or just jpg compression artifacts?
It‘s intended. I had a Samsung plasma tv in the past, which always looked restless if you took a closer look. Maybe Samsung added it to prevent burn in. I add dynamic noise to get this restless messy look. It can also be disabled.

Another one from my Xperia Xz1, that doesn’t do really well with precision at above 4x scale but powerful enough to run every shader there is.

I think I’ve gotten closer to my goal of obtaining a preset that combines the blending potential of composite with the color vibrancy of RGB while retaining as much sharpness as possible. This is using a preset consisting of NTSC-Colors and CRT-Guest-Advanced-NTSC:
While it’s not razor-sharp, it’s still sharp enough that you don’t feel like it’s murdering all the details of the pixel art just to blend that damn waterfall. The colors are, of course, nice and vivid, courtesy of disabling all the NTSC parameters that tend to mute them, as well as giving them a nice boost through the NTSC-Colors shader. I’ve also begun to experiment with the Mask Boost parameter, which gives a nice brightness boost along with getting back some of the mask detail lost through the Bloom parameters. The image is actually bright enough that I can more than comfortably play with my monitor’s backlight all the way down to the lowest setting, and according to the 240p suite, while I am missing some color bars, that is purely down to the NTSC-Colors shader, which is a tradeoff I am willing to live with given how much it improves the colors of the image IMO.
Here is the preset, if anyone wants to check it out:

Trying to bright up 4K, I find it more difficult than 1080p. But I think is getting better.

Alright, this is my first post (so I can only post 1 image, so here goes!), after watching this thread for awhile, here is my favorite shader settings so far. Works very well with non-integer scaling. The rainbow effect from ntsc is visible too…
It’s nes-raw decoder + checkerboard dithering + ntsc 3 phase composite + lanczos3-fast + zfast-crt
Tweaked settings:
UseGamma = “0.200000”
CD_BLEND_LEVEL = “0.400000”
CD_MITIG_LINES = “1.000000”
LANCZOS3_ANTI_RINGING = “0.000000”
BLURSCALEX = “0.400000”
BRIGHTBOOST = “1.400000”
MASK_DARK = “0.350000”
EDIT: Forgot the gamma setting (checkboard-dither), thanks for the approved post. I will post later, once I can post more than 1 image

I hope it’s okay to reply to myself, here are the other screenshots, same settings nes-raw decoder + checkerboard dithering + ntsc 3 phase composite + lanczos3-fast + zfast-crt Tweaked settings: UseGamma = “0.200000” CD_BLEND_LEVEL = “0.400000” CD_MITIG_LINES = “1.000000” LANCZOS3_ANTI_RINGING = “0.000000” BLURSCALEX = “0.400000” BRIGHTBOOST = “1.400000” MASK_DARK = “0.350000”

zfast-crt-composite overhaul to be kind of crt-consumer light version. Here on my old xiaomi note 3 pro, on top of chromaticity and simple color controls, GLSL. That cellphone produces the exact same image as on my PC without any precision issues.

Ok, 2nd 4K brightness attempt, I hope there isn’t too much this time…

nes-raw-decoder + lanczos3-fast + ntsc 3 phase 256px composite + zfast-crt. Looks great!, still provides subtle rainbow, subtle blending, text looks more clean. Again this is nice for non-integer scaling and very lightweight…
shader parameters:
LANCZOS3_ANTI_RINGING = "0.000000"
BLURSCALEX = "0.400000"
BRIGHTBOOST = "1.500000"
MASK_DARK = "0.350000"
Edit: Just a quick edit for clarity on the order of the shaders… I just noticed the screenshots had the “saved message” re-doing it…
