I used nVIDIA Shadow Play to take these but there are other methods available.
The files can also be viewed on an SDR display by the way.

A little experiment.
In the first image if you look closely at the ceiling, or at other dark areas, there are several black dots. I think they’re there for some kind of dithering, to have some sort of shadow effect, but even with my usual settings, which aren’t thtat bright, they’re noticeable. Looking directly at the monitor and not at a screenshot, it’s worse.
Messing around with the usual settings (brightness, bloom and such) didn’t do the trick. I think that the main problem is just the LED technology, which lacks something in the contrast/black areas (I have an Asus MX7AQ monitor, not bad at all, but still). So here’s what I did: I’ve added a little of Black Level (value: -10). That seemed to work, without impacting too much on the overall balance of the image (second screenshot).
Modifying the Contrast value produced a similar effect, but impacted more on the overall balance of the image. So, Black Level is the way to go if you have a similar issue.
Let me know what you think (open in a new tab).

Lots of games require brightness or gamma adjustments. (Especially arcade games) Bottom pic definitely better
Here are some more HDR screenshots, showing the blending of dithering in some TurboGrafx16 games in order to make new colours while attempting to preserve some sharpness.
The following files are all in jxr format so you’ll need a jxr viewer to view them if you’re not using Windows 10 or 11.

Here’s a link to a jxr viewer. The native viewer in Windows 10 and 11 is probably better though.

Trying to emulate those fascinating dot matrix advertising led displays, I can stay dazed in front of them on the street while paying zero attention to the content 
When this rotates, it is hypnotic to me;

This is sexy. The bloom variant is my favorite one followed by the smooth version. Also like that you can switch over to the xm29plus lut on the fly.

Hi thanks again. Is your shader exist for 4k displays? Thanks

Thanks I will give a try regards
Imitating Trinitron colors on Android with crt-sines. Android looks different than PC so had to use something like color-profiler to tweak hue and every screen is a bit different than another.

After these days of rest, I made a new preset based on my old presets, but I made a few tweaks. I wanted to make it a bit more realistic. Your opinions are always welcome…

@Hyllian I wanted to experiment swapping out the LUT pass with the grade shader. Came out interesting I think.

Place preset right into the shaders folder

Nice! It looks like the LUT-1 (ntsc from guest).
Though the preset got the default royale params.

Thanks lol. I tried copying over everything you used for the “bloom” preset but it wasn’t coming out right for some reason, the diffusion setting was still showing that weird “halo” that you spoke of around things so I knew something was off so I ended up just doing my own custom settings and leaving other settings that you may have tweaked on default. I switched the first LUT setting (enabled it) in the grade shader and that made a world of a difference in colors. I might try switching that in my presets next to see what happens as well.
Also @Hyllian is there a way to make a 1440p version? I saw in another post on how to do the 4k variant (haven’t tried it yet though). Curious because who knows, this may become a new project to go along with the guest presets. Guest and royale presets together sounds nice actually.
I would just disable vertical curvature and lower horizontal curvature a bit to avoid you know what from occurring but that’s just me.
Other than that, it looks pretty realistic to me.
Looks nice and sharp in the screenshots as well.

Never tried. If you’re interested, you can tweak that same parameter I mentioned to make it work in 4k. So you can find a good value for 1440p. I’ll only work in 1080p for now, as it already encompass a lot of presets and next version will have a ntsc variant incorporated.
